Security and Electronic Signature Standards

AGENCY: Health Care Financing Administration (HCFA), HHS.

ACTION: Proposed rule.

-----------------------------------------------------------------------

SUMMARY: This rule proposes standards for the security of individual 
health information and electronic signature use by health plans, health 
care clearinghouses, and health care providers. The health plans, 
health care clearinghouses, and health care providers would use the 
security standards to develop and maintain the security of all 
electronic individual health information. The electronic signature 
standard is applicable only with respect to use with the specific 
transactions defined in the Health Insurance Portability and 
Accountability Act of 1996, and when it has been determined that an 
electronic signature must be used.
    The use of these standards would improve the Medicare and Medicaid 
programs, and other Federal health programs and private health 
programs, and the effectiveness and efficiency of the health care 
industry in general. This rule would implement some of the requirements 
of the Administrative Simplification subtitle of the Health Insurance 
Portability and Accountability Act of 1996.

I. Background

[Please label written or e-mailed comments about this section with 
the subject: Background]

    In order to administer their programs, the Department of Health and 
Human Services, other Federal agencies, State Medicaid agencies, 
private health plans, health care providers, and health care 
clearinghouses must assure their customers (such as patients, insured, 
providers, and health care plans) that the confidentiality and privacy 
of health care information they electronically collect, maintain, use, 
or transmit is secure. Security of health information is especially 
important when health information can be directly linked to an 
individual.
    Confidentiality is threatened not only by the risk of improper 
access to electronically stored information, but also by the risk of 
interception during electronic transmission of the information.
    In addition to the need to ensure electronic health care 
information is secure and confidential, there is a potential need to 
associate signature capability with information being electronically 
stored or transmitted. Today, there are numerous forms of electronic 
signatures, ranging from biometric devices to digital signature. To 
satisfy the legal and time-tested characteristics of a written 
signature, however, an electronic signature must do the following:
    <bullet> Identify the signatory individual,
    <bullet> Assure the integrity of a document's content, and
    <bullet> Provide for nonrepudiation; that is, strong and 
substantial evidence that will make it difficult for the signer to 
claim that the electronic representation is not valid. Currently, the 
only technically mature electronic signature meeting the above criteria 
is the digital signature. There is no national standard for security or 
electronic signatures. Of necessity, each health care provider, health 
care plan, and health care entity

[[Page 43243]]

has defined its own security requirements.

A. Legislation

    The Congress included provisions to address the need for security 
and electronic signature standards and other administrative 
simplification issues in the Health Insurance Portability and 
Accountability Act of 1996 (HIPAA), Public Law 104-191, which was 
enacted on August 21, 1996. Through subtitle F of title II of that law, 
the Congress added to title XI of the Social Security Act a new part C, 
entitled ``Administrative Simplification.'' (Public Law 104-191 affects 
several titles in the United States Code. Hereafter, we refer to the 
Social Security Act as the Act; we refer to the other laws cited in 
this document by their names.) The purpose of this part C is to improve 
the Medicare and Medicaid programs, in particular, and the efficiency 
and effectiveness of the health care system, in general, by encouraging 
the development of a health information system through the 
establishment of standards and requirements to facilitate the 
electronic maintenance and transmission of certain health information.
    Part C of title XI of the Act consists of sections 1171 through 
1179. These sections define various terms and impose several 
requirements on HHS, health plans, health care clearinghouses, and 
certain health care providers concerning electronic transmission of 
health information.
    The first section, section 1171 of the Act, establishes definitions 
for purposes of part C of title XI for the following terms: code set, 
health care clearinghouse, health care provider, health information, 
health plan, individually identifiable health information, standard, 
and standard setting organization.
    Section 1172 of the Act makes any standard adopted under part C 
applicable to: (1) Health plans, (2) health care clearinghouses, and 
(3) health care providers that transmit any health information in 
electronic form in connection with the transactions referred to in 
section 1173(a)(1) of the Act. The security standard to be adopted 
under Part C is not restricted to the transactions referred to in 
section 1173(a)(1) of the Act, but is applicable to any health 
information pertaining to an individual that is electronically 
maintained or transmitted. This section also contains the following 
requirements concerning standard setting:
    <bullet> The Secretary may adopt a standard developed, adopted, or 
modified by a standard setting organization (that is, an organization 
accredited by the American National Standards Institute (ANSI)) that 
has consulted with the National Uniform Billing Committee (NUBC), the 
National Uniform Claim Committee (NUCC), Workgroup for Electronic Data 
Interchange (WEDI), and the American Dental Association (ADA).
    <bullet> The Secretary may also adopt a standard other than one 
established by a standard setting organization, if the different 
standard will reduce costs for health care providers and health plans, 
the different standard is promulgated through negotiated rulemaking 
procedures, and the Secretary consults with each of the above-named 
groups.
    <bullet> If no standard has been adopted by any standard setting 
organization, the Secretary must rely on the recommendations of the 
National Committee on Vital and Health Statistics (NCVHS) and consult 
with each of the above-named groups.
    In complying with the requirements of part C of title XI, the 
Secretary must rely on the recommendations of the NCVHS, consult with 
appropriate State, Federal, and private agencies or organizations, and 
publish the NCVHS recommendations in the Federal Register.
    Paragraph (a) of section 1173 of the Act requires that the 
Secretary adopt standards for financial and administrative 
transactions, and data elements for those transactions, to enable 
health information to be exchanged electronically. Standards are 
required for the following transactions: health claims, health 
encounter information, health claims attachments, health plan 
enrollments and disenrollments, health plan eligibility, health care 
payment and remittance advice, health plan premium payments, first 
report of injury, health claim status, and referral certification and 
authorization. In addition, the Secretary is required to adopt 
standards for any other financial and administrative transactions that 
are determined to be appropriate by the Secretary.
    Paragraph (b) of section 1173 of the Act requires the Secretary to 
adopt standards for unique health identifiers for all individuals, 
employers, health plans, and health care providers and requires further 
that the adopted standards specify for what purposes unique health 
identifiers may be used.
    Paragraphs (c) through (f) of section 1173 of the Act require the 
Secretary to establish standards for code sets for each data element 
for each health care transaction listed above, security standards for 
health care information systems, standards for electronic signatures 
(established together with the Secretary of Commerce), and standards 
for the transmission of data elements needed for the coordination of 
benefits and sequential processing of claims. Compliance with 
electronic signature standards will be deemed to satisfy both State and 
Federal requirements for written signatures with respect to the 
transactions listed in paragraph (a) of section 1173 of the Act.
    In section 1174 of the Act, the Secretary is required to establish 
standards for all of the above transactions, except claims attachments, 
by February 21, 1998. The standards for claims attachments must be 
established by February 21, 1999. Generally, after a standard is 
established, it cannot be changed during the first year after adoption 
except for changes that are necessary to permit compliance with the 
standard. Modifications to any of these standards may be made after the 
first year, but not more frequently than once every 12 months. The 
Secretary must also ensure that procedures exist for the routine 
maintenance, testing, enhancement, and expansion of code sets and that 
there are crosswalks from prior versions.
    Section 1175 of the Act prohibits health plans from refusing to 
process or delaying the processing of a transaction that is presented 
in standard format. The Act's requirements are not limited to health 
plans; however, each person to whom a standard or implementation 
specification applies is required to comply with the standard within 24 
months (or 36 months for small health plans) of its adoption. A health 
plan or other entity may, of course, comply voluntarily before the 
effective date. A person may comply by using a health care 
clearinghouse to transmit or receive the standard transactions. 
Compliance with modifications to standards or implementation 
specifications must be accomplished by a date designated by the 
Secretary. This date may not be earlier than 180 days from the notice 
of change.
    Section 1176 of the Act establishes a civil monetary penalty for 
violation of the provisions in part C of title XI of the Act, subject 
to several limitations. Penalties may not be more than $100 per person 
per violation and not more than $25,000 per person for violations of a 
single standard for a calendar year. The procedural provisions in 
section 1128A of the Act, ``Civil Monetary Penalties,'' are applicable.
    Section 1177 of the Act establishes penalties for a knowing misuse 
of unique health identifiers and individually identifiable health 
information: (1) A fine of not more than $50,000 and/or imprisonment of 
not

[[Page 43244]]

more than 1 year; (2) if misuse is ``under false pretenses,'' a fine of 
not more than $100,000 and/or imprisonment of not more than 5 years; 
and (3) if misuse is with intent to sell, transfer, or use individually 
identifiable health information for commercial advantage, personal 
gain, or malicious harm, a fine of not more than $250,000 and/or 
imprisonment of not more than 10 years. Note that these penalties do 
not affect any other penalties which may be imposed by other Federal 
programs, including ERISA.
    Under section 1178 of the Act, the provisions of part C of title XI 
of the Act, as well as any standards established under them, supersede 
any State law that is contrary to them. However, the Secretary may, for 
statutorily-specified reasons, waive this provision.
    Finally, section 1179 of the Act makes the above provisions 
inapplicable to financial institutions or anyone acting on behalf of a 
financial institution when ``authorizing, processing, clearing, 
settling, billing, transferring, reconciling, or collecting payments 
for a financial institution.''

    (Concerning this last provision, the conference report, in its 
discussion on section 1178, states:
    ``The conferees do not intend to exclude the activities of 
financial institutions or their contractors from compliance with the 
standards adopted under this part if such activities would be 
subject to this part. However, conferees intend that this part does 
not apply to use or disclosure of information when an individual 
utilizes a payment system to make a payment for, or related to, 
health plan premiums or health care. For example, the exchange of 
information between participants in a credit card system in 
connection with processing a credit card payment for health care 
would not be covered by this part. Similarly sending a checking 
account statement to an account holder who uses a credit or debit 
card to pay for health care services, would not be covered by this 
part. However, this part does apply if a company clears health care 
claims, the health care claims activities remain subject to the 
requirements of this part.'') (H.R. Rep. No. 736, 104th Cong., 2nd 
Sess. 268-269 (1996))

B. Process for Developing National Standards

    The Secretary has formulated a five-part strategy for developing 
and implementing the standards mandated under part C of title XI of the 
Act:
    1. To ensure necessary interagency coordination and required 
interaction with other Federal departments and the private sector, 
establish interdepartmental implementation teams to identify and assess 
potential standards for adoption. The subject matter of the teams 
includes claims/encounters, identifiers, enrollment/eligibility, 
systems security and electronic signature, and medical coding 
classification. Another team addresses cross-cutting issues and 
coordinates the subject matter teams. The teams consult with external 
groups such as the NCVHS' Workgroup on Data Standards, WEDI, the ANSI's 
Healthcare Informatics Standards Board (HISB), the NUCC, the NUBC, and 
the ADA. The teams are charged with developing regulations and other 
necessary documents and making recommendations for the various 
standards to the HHS Data Council through its Committee on Health Data 
Standards. (The HHS Data Council is the focal point for consideration 
of data policy issues. It reports directly to the Secretary and advises 
the Secretary on data standards and privacy issues.)
    2. Develop recommendations for standards to be adopted.
    3. Publish proposed rules in the Federal Register describing the 
standards. Each proposed rule provides the public with a 60-day comment 
period.
    4. Analyze public comments and publish the final rules in the 
Federal Register.
    5. Distribute standards and coordinate preparation and distribution 
of implementation guides.
    This strategy affords many opportunities for involvement of 
interested and affected parties in standards development and adoption 
by enabling them to:
    <bullet> Participate with standards setting organizations.
    <bullet> Provide written input to the NCVHS.
    <bullet> Provide written input to the Secretary of HHS.
    <bullet> Provide testimony at NCVHS'' public meetings.
    <bullet> Comment on the proposed rules for each of the proposed 
standards.
    <bullet> Invite HHS staff to meetings with public and private 
sector organizations or meet directly with senior HHS staff involved in 
the implementation process.
    The implementation teams charged with reviewing standards for 
designation as required national standards under the statute have 
defined, with significant input from the health care industry, a set of 
principles for guiding choices for the standards to be adopted by the 
Secretary. These principles are based on direct specifications in 
HIPAA, the purpose of the law, and generally desirable principles. To 
be designated as an HIPAA standard, each standard should:
    1. Improve the efficiency and effectiveness of the health care 
system by leading to cost reductions for or improvements in benefits 
from electronic health care transactions.
    2. Meet the needs of the health data standards user community, 
particularly health care providers, health plans, and health care 
clearinghouses.
    3. Be consistent and uniform with the other HIPAA standards--their 
data element definitions and codes and their privacy and security 
requirements--and, secondarily, with other private and public sector 
health data standards.
    4. Have low additional development and implementation costs 
relative to the benefits of using the standard.
    5. Be supported by an ANSI-accredited standards developing 
organization or other private or public organization that will ensure 
continuity and efficient updating of the standard over time.
    6. Have timely development, testing, implementation, and updating 
procedures to achieve administrative simplification benefits faster.
    7. Be technologically independent of the computer platforms and 
transmission protocols used in electronic health transactions, except 
when they are explicitly part of the standard.
    8. Be precise and unambiguous, but as simple as possible.
    9. Keep data collection and paperwork burdens on users as low as is 
feasible.
    10. Incorporate flexibility to adapt more easily to changes in the 
health care infrastructure (such as new services, organizations, and 
provider types) and information technology.
    A master data dictionary providing for common data definitions 
across the standards selected for implementation under HIPAA will be 
developed and maintained. We intend for the data element definitions to 
be precise, unambiguous, and consistently applied. The transaction-
specific reports and general reports from the master data dictionary 
will be readily available to the public. At a minimum, the information 
presented will include data element names, definitions, and appropriate 
references to the transactions where they are used.
    This proposed rule would establish the security standard and 
electronic signature standard for health care information and 
individually identifiable health care information maintained or 
transmitted electronically. The remaining standards are grouped, to the 
extent possible, by subject matter and audience in other regulations. 
We anticipate publishing

[[Page 43245]]

several separate regulation documents to promulgate the remaining 
standards required under HIPAA.

II. Provisions of this Proposed Rule

[Please label written comments or e-mailed comments about this 
section with the subject: Introduction/Applicability]

    We propose to add a new part to title 45 of the Code of Federal 
Regulations for health plans, health care providers, and health care 
clearinghouses in general. The new part would be part 142 of title 45 
and would be titled ``Administrative Requirements.'' Subpart A would 
contain the general provisions for this part, including the general 
definitions and general requirements for health plans. Subpart C would 
contain provisions specific to securing health information used in any 
electronic transmission or stored format.
    In this proposed rule, we propose a standard for security of health 
information. This rule would establish that health plans, health care 
clearinghouses, and health care providers must have the security 
standard in place to comply with the statutory requirement that health 
care information and individually identifiable health care information 
be protected to ensure privacy and confidentiality when health 
information is electronically stored, maintained, or transmitted. The 
Congress mandated a separate standard for electronic signature, 
therefore, this proposed security standard also addresses the selected 
standard for electronic signature. The proposed security standard does 
not require the use of an electronic signature, but specifies the 
standard for an electronic signature that must be followed if such a 
signature is used. If an entity elects to use an electronic signature, 
it must comply with the electronic signature standard.

A. Applicability

    With the exception of the security provisions, section 262 of HIPAA 
applies to any health plan, any health care clearinghouse, and any 
health care provider that transmits any health information in 
electronic form in connection with transactions referred to in section 
1173(a)(1) of the Act. The security provisions of section 262 of HIPAA 
apply to any health plan, any health care clearinghouse, and any health 
care provider that electronically maintains or transmits any health 
information relating to an individual.
    Our proposed rules (at 45 CFR 142.102) would apply to the health 
plans and health care clearinghouses as well, but we would clarify the 
statutory language in our regulations for health care providers. With 
the exception of the security regulation, we would have the regulations 
apply to any health care provider only when electronically transmitting 
any of the transactions to which section 1173(a)(1) of the Act refers.
    Electronic transmissions would include transactions using all 
media, even when the information is physically moved from one location 
to another using magnetic tape, disk, or compact disc (cd) media. 
Transmissions over the Internet (wide-open), Extranet (using Internet 
technology to link a business with information only accessible to 
collaborating parties), leased lines, dial-up lines, and private 
networks are all included. Telephone voice response and ``faxback'' (a 
request for information made via voice using a fax machine and 
requested information returned via that same machine as a fax) systems 
would not be included. We solicit comments concerning any adverse 
impact the above statement concerning voice response or faxback may 
have upon the security of the health information in the commenter's 
care.
    With the exception of the security regulation, our regulations 
would apply to health care clearinghouses when transmitting 
transactions to, and receiving transactions from, a health care 
provider or health plan that transmits and receives standard 
transactions (as defined under ``transaction'') and at all times when 
transmitting to or receiving electronic transactions from another 
health care clearinghouse. The security regulation would apply to 
health care clearing houses electronically maintaining or transmitting 
any health information pertaining to an individual.
    Entities that offer on-line interactive transmission must comply 
with the standards. The Hypertext Markup Language (HTML) interaction 
between a server and a browser by which the data elements of a 
transaction are solicited from a user would not have to use the 
standards (with the exception of the security standard), although the 
data content must be equal to that required for the standard. Once the 
data elements are assembled into a transaction by the server, the 
transmitted transaction would have to comply with the standards.
    With the exception of the security portion, the law would apply to 
each health care provider when transmitting or receiving any of the 
specified electronic transactions. The security regulation would apply 
to each health care provider electronically maintaining or transmitting 
any health information pertaining to an individual.
    The law applies to health plans for all transactions. Section 
142.104 would contain the following provisions (from section 1175 of 
the Act):
    If a person desires to conduct a transaction (as defined in 
Sec. 142.103) with a health plan as a standard transaction, the 
following apply:
    (1) The health plan may not refuse to conduct the transaction as a 
standard transaction.
    (2) The health plan may not delay the transaction or otherwise 
adversely affect, or attempt to adversely affect, the person or the 
transaction on the basis that the transaction is a standard 
transaction.
    (3) The information transmitted and received in connection with the 
transaction must be in the form of standard data elements of health 
information.
    As a further requirement, we would provide that a health plan that 
conducts transactions through an agent assure that the agent meets all 
the requirements of part 142 that apply to the health plan.
    Section 142.105 would state that a person or other entity may meet 
the transaction requirements of Sec. 142.104 by either--
    (1) Transmitting and receiving standard data elements, or
    (2) Submitting nonstandard data elements to a health care 
clearinghouse for processing into standard data elements and 
transmission by the health care clearinghouse and receiving standard 
data elements through the clearinghouse.
    Health care clearinghouses would be able to accept nonstandard 
transactions for the sole purpose of translating them into standard 
transactions for sending customers and would be able to accept standard 
transactions and translate them into nonstandard formats for receiving 
customers. We would state in Sec. 142.105 that the transmission of 
nonstandard transactions, under contract, between a health plan or a 
health care provider and a health care clearinghouse would not violate 
the law.
    With the exception of the security standard, transmissions within a 
corporate entity would not be required to comply with the standards. A 
hospital that is wholly owned by a managed care company would not have 
to use the transaction standards to pass encounter information back to 
the home office, but it would have to use the standard claims 
transaction to submit a claim to another payer. Another example might 
be transactions within Federal agencies and their contractors and 
between State agencies within the same State. For example, Medicare 
enters into contracts with insurance

[[Page 43246]]

companies and common working file sites that process Medicare claims 
using government furnished software. There is constant communication, 
on a private network, between HCFA Central Office and the Medicare 
carriers, intermediaries, and common working file sites. This 
communication may continue in nonstandard mode. However, these 
contractors would be required to comply with the transaction standards 
when exchanging any of the transactions covered by HIPAA with an entity 
outside these ``corporate'' boundaries.
    The security standard is applicable to all health care information 
electronically maintained or used in an electronic transmission, 
regardless of format (standard transaction or a proprietary format); no 
distinction is made between internal corporate entity communication or 
communication external to the corporate entity.
    Although there are situations in which the use of the standards is 
not required (for example, health care providers may continue to submit 
paper claims and employers are not required to use any of the standard 
transactions), we stress that a standard may be used voluntarily in any 
situation in which it is not required.
    This proposed regulation would not mandate the use of electronic 
signatures with any specific transaction at this time. Instead, the 
regulation proposes that whenever an electronic signature is required 
for an electronic transaction by law, regulation, or contract, the 
signature must meet the standard established in the regulation at 
Sec. 142.310. Use of this standard would satisfy any Federal or State 
requirement for a signature, either electronic or on paper.
    We note that the ANSI X12N standards for individual transactions 
which have been proposed for adoption as national standards in a 
separate proposed rule do not require the use of electronic signatures. 
Standards for additional transactions that the Secretary may propose 
for adoption in the future, including one for claims attachments, may 
contain such requirements. We solicit comments on whether electronic 
signatures should be required for any specific transactions or under 
specific circumstances and what effect such requirements would have on 
electronic health care transactions.
    We also note that the NCVHS is required by HIPAA to report to the 
Secretary recommendations and legislative proposals for uniform data 
standards for patient medical record information and the electronic 
exchange of such information, with the implication that HHS should rely 
on such recommendations to adopt such standards or propose the passage 
of such legislation by the Congress. We solicit comments on whether the 
standard proposed below for electronic signatures would be appropriate 
for consideration as part of such standards.

B. Definitions

[Please label written or e-mailed comments about this section with 
the subject: Definitions]

    Section 1171 of the Act defines several terms and our proposed 
rules would, for the most part, simply restate the law. The terms that 
we are defining in this proposed rule follow:
1. Code Set
    We would define ``code set'' as section 1171(1) of the Act does: 
``code set'' means any set of codes used for encoding data elements, 
such as tables of terms, medical concepts, medical diagnostic codes, or 
medical procedure codes.
2. Health Care Clearinghouse
    We would define ``health care clearinghouse'' as section 1171(2) of 
the Act does, but we are adding a further, clarifying sentence. The 
statute defines a ``health care clearinghouse'' as a public or private 
entity that processes or facilitates the processing of nonstandard data 
elements of health information into standard data elements. We would 
further explain that such an entity is one that currently receives 
health care transactions from health care providers or other entities, 
translates the data from a given format into one acceptable to the 
intended recipient and forwards the processed transaction to 
appropriate payers and clearinghouses, as necessary, for further 
action.
    There are currently a number of private clearinghouses that perform 
this function for health care providers. For purposes of this rule, we 
would consider billing services, repricing companies, community health 
management information systems or community health information systems, 
value-added networks, and switches that perform this function to be 
health care clearinghouses.
3. Health Care Provider
    As defined by section 1171(3) of the Act, a ``health care 
provider'' is a provider of services as defined in section 1861(u) of 
the Act, a provider of medical or other health services as defined in 
section 1861(s) of the Act, and any other person who furnishes health 
care services or supplies. Our regulations would define ``health care 
provider'' as the statute does and clarify that the definition of a 
health care provider is limited to those entities that furnish, or bill 
and are paid for, health care services in the normal course of 
business.
    For a more detailed discussion of the definition of health care 
provider, we refer the reader to our proposed rule, HCFA-0045-P, 
Standard Health Care Provider, 63 FR 25320, published May 7, 1998.
4. Health Information
    ``Health information,'' as defined in section 1171 of the Act, 
means any information, whether oral or recorded in any form or medium, 
that--
    <bullet> Is created or received by a health care provider, health 
plan, public health authority, employer, life insurer, school or 
university, or health care clearinghouse; and
    <bullet> Relates to the past, present, or future physical or mental 
health or condition of an individual; the provision of health care to 
an individual; or the past, present, or future payment for the 
provision of health care to an individual.
    We propose the same definition for our regulations.
5. Health Plan
    We propose that a ``health plan'' be defined essentially as section 
1171 of the Act defines it. Section 1171 of the Act cross refers to 
definitions in section 2791 of the Public Health Service Act (as added 
by Public Law 104-191, 42 U.S.C. 300gg-91); we would incorporate those 
definitions as currently stated into our proposed definitions for the 
convenience of the public. We note that the term ``health plan'' is 
also defined in other statutes, such as the Employee Retirement Income 
Security Act of 1974 (ERISA). Our definitions are based on the roles of 
plans in conducting administrative transactions, and any differences 
should not be construed to affect other statutes.
    For purposes of implementing the provisions of administrative 
simplification, a ``health plan'' would be an individual or group 
health plan that provides, or pays the cost of, medical care. This 
definition includes, but is not limited to, the 13 types of plans 
listed in the statute. On the other hand, plans such as property and 
casualty insurance plans and workers compensation plans, which may pay 
health care costs in the course of administering nonhealth care 
benefits, are not considered to be health plans in the proposed 
definition of health plan. Of course, these plans may voluntarily adopt 
these standards for their own business needs. At some

[[Page 43247]]

future time, the Congress may choose to expressly include some or all 
of these plans in the list of health plans that must comply with the 
standards.
    Health plans often carry out their business functions through 
agents, such as plan administrators (including third party 
administrators), entities that are under ``administrative services 
only'' (ASO) contracts, claims processors, and fiscal agents. These 
agents may or may not be health plans in their own right; for example, 
a health plan acting as another health plan's agent as another line of 
business. As stated earlier, a health plan that conducts HIPAA 
transactions through an agent is required to assure that the agent 
meets all HIPAA requirements that apply to the plan itself.
    ``Health plan'' includes the following, singly or in combination:
    a. ``Group health plan'' (as currently defined by section 2791(a) 
of the Public Health Service Act). A group health plan is a plan that 
has 50 or more participants (as the term ``participant'' is currently 
defined by section 3(7) of ERISA) or is administered by an entity other 
than the employer that established and maintains the plan. This 
definition includes both insured and self-insured plans. We define 
``participant'' separately below.
    Section 2791(a)(1) of the Public Health Service Act defines ``group 
health plan'' as an employee welfare benefit plan (as defined in 
current section 3(1) of ERISA) to the extent that the plan provides 
medical care, including items and services paid for as medical care, to 
employees or their dependents directly or through insurance, or 
otherwise.
    b. ``Health insurance issuer'' (as currently defined by section 
2791(b) of the Public Health Service Act).
    Section 2791(b) of the Public Health Service Act currently defines 
a ``health insurance issuer'' as an insurance company, insurance 
service, or insurance organization that is licensed to engage in the 
business of insurance in a State and is subject to State law that 
regulates insurance.
    c. ``Health maintenance organization'' (as currently defined by 
section 2791(b) of the Public Health Service Act).
    Section 2791(b) of the Public Health Service Act currently defines 
a ``health maintenance organization'' as a Federally qualified health 
maintenance organization, an organization recognized as such under 
State law, or a similar organization regulated for solvency under State 
law in the same manner and to the same extent as such a health 
maintenance organization. These organizations may include preferred 
provider organizations, provider sponsored organizations, independent 
practice associations, competitive medical plans, exclusive provider 
organizations, and foundations for medical care.
    d. Part A or Part B of the Medicare program (title XVIII of the 
Act).
    e. The Medicaid program (title XIX of the Act).
    f. A ``Medicare supplemental policy'' as defined under section 
1882(g)(1) of the Act.
    Section 1882(g)(1) of the Act defines a ``Medicare supplemental 
policy'' as a health insurance policy that a private entity offers a 
Medicare beneficiary to provide payment for expenses incurred for 
services and items that are not reimbursed by Medicare because of 
deductible, coinsurance, or other limitations under Medicare. The 
statutory definition of a Medicare supplemental policy excludes a 
number of plans that are generally considered to be Medicare 
supplemental plans, such as health plans for employees and former 
employees and for members and former members of trade associations and 
unions. A number of these health plans may be included under the 
definitions of ``group health plan'' or ``health insurance issuer'', as 
defined in paragraphs a. and b. above.
    g. A ``long-term care policy,'' including a nursing home fixed-
indemnity policy. A ``long-term care policy'' is considered to be a 
health plan regardless of how comprehensive it is. We recognize the 
long-term care insurance segment of the industry is largely unautomated 
and we welcome comments regarding the impact of HIPAA on the long-term 
care segment.
    h. An employee welfare benefit plan or any other arrangement that 
is established or maintained for the purpose of offering or providing 
health benefits to the employees of two or more employers. This 
includes plans that are referred to as multiple employer welfare 
arrangements (``MEWAs'').
    i. The health care program for active military personnel under 
title 10 of the United States Code.
    j. The veterans health care program under chapter 17 of title 38 of 
the United States Code.
    This health plan primarily furnishes medical care through hospitals 
and clinics administered by the Department of Veterans Affairs for 
veterans with a service-connected disability that is compensable. 
Veterans with nonservice-connected disabilities (and no other health 
benefit plan) may receive health care under this health plan to the 
extent resources and facilities are available.
    k. The Civilian Health and Medical Program of the Uniformed 
Services (CHAMPUS), as defined in 10 U.S.C. 1072(4).
    CHAMPUS primarily covers services furnished by civilian medical 
providers to dependents of active duty members of the uniformed 
services and retirees and their dependents under age 65.
    l. The Indian Health Service program under the Indian Health Care 
Improvement Act (25 U.S.C. 1601 et seq.).
    This program furnishes services, generally through its own health 
care providers, primarily to persons who are eligible to receive 
services because they are of American Indian or Alaskan Native descent.
    m. The Federal Employees Health Benefits Program under 5 U.S.C. 
chapter 89.
    This program consists of health insurance plans offered to active 
and retired Federal employees and their dependents. Depending on the 
health plan, the services may be furnished on a fee-for-service basis 
or through a health maintenance organization.

    (Note: Although section 1171(5)(M) of the Act refers to the 
``Federal Employees Health Benefit Plan,'' this and any other rules 
adopting administrative simplification standards will use the 
correct name, the Federal Employees Health Benefits Program. One 
health plan does not cover all Federal employees; there are over 350 
health plans that provide health benefits coverage to Federal 
employees, retirees, and their eligible family members. Therefore, 
we will use the correct name, the Federal Employees Health Benefits 
Program, to make clear that the administrative simplification 
standards apply to all health plans that participate in the 
Program.)

    n. Any other individual or group health plan, or combination 
thereof, that provides or pays for the cost of medical care.
    We would include a fourteenth category of health plan in addition 
to those specifically named in HIPAA, as there are health plans that do 
not readily fit into the other categories but whose major purpose is 
providing health benefits. The Secretary would determine which of these 
plans are health plans for purposes of title II of HIPAA. This category 
would include the Medicare Plus Choice plans that will become available 
as a result of section 1855 of the Act as amended by section 4001 of 
the Balanced Budget Act of 1997 (Public Law 105-33) to the extent that 
these health plans do not fall under any other category.

[[Page 43248]]

6. Small Health Plan
    We would define a ``small health plan'' as a group health plan with 
fewer than 50 participants.
    The HIPAA does not define a ``small health plan'' but instead 
leaves the definition to be determined by the Secretary. The Conference 
Report suggests that the appropriate definition of a ``small health 
plan'' is found in current section 2791(a) of the Public Health Service 
Act, which is a group health plan with fewer than 50 participants. We 
would also define small individual health plans as those with fewer 
than 50 participants.
7. Individually Identifiable Health Information
    Section 1171(6) states the term ``individually identifiable health 
information'' means any information, including demographic information 
collected from an individual, that--
    a. Is created or received by a health care provider, health plan, 
employer, or health care clearinghouse; and
    b. Relates to the past, present or future physical or mental health 
or condition of an individual, the provision of health care to an 
individual, or the past, present, or future payment for the provision 
of health care to an individual, and
    (i) Identifies the individual, or
    (ii) With respect to which there is a reasonable basis to believe 
that the information can be used to identify the individual.
8. Standard
    Section 1171 of the Act defines ``standard,'' when used with 
reference to a data element of health information or a transaction 
referred to in section 1173(a)(1) of the Act, as any such data element 
or transaction that meets each of the standards and implementation 
specifications adopted or established by the Secretary with respect to 
the data element or transaction under sections 1172 through 1174 of the 
Act.
    Under our definition, the security standard would be a set of 
requirements adopted or established to preserve and maintain the 
confidentiality and privacy of electronically stored, maintained, or 
transmitted health information promulgated either by an organization 
accredited by the ANSI or HHS.
9. Transaction
    ``Transaction'' would mean the exchange of information between two 
parties to carry out financial and administrative activities related to 
health care. A transaction would be (a) any of the transactions listed 
in section 1173(a)(2) of the Act, and (b) any determined appropriate by 
the Secretary in accordance with section 1173(a)(1)(B) of the Act. We 
present them below in the order in which we propose to list them in the 
regulations text.
    A ``transaction'' would mean any of the following:
    a. Health claims or equivalent encounter information. This 
transaction may be used to submit health care claim billing 
information, encounter information, or both, from health care providers 
to payers, either directly or via intermediary billers and claims 
clearinghouses.
    b. Health care payment and remittance advice. This transaction may 
be used by a health plan to make a payment to a financial institution 
for a health care provider (sending payment only), to send an 
explanation of benefits remittance advice directly to a health care 
provider (sending data only), or to make payment and send an 
explanation of benefits remittance advice to a health care provider via 
a financial institution (sending both payment and data).
    c. Coordination of benefits. This transaction set can be used to 
transmit health care claims and billing payment information between 
payers with different payment responsibilities where coordination of 
benefits is required or between payers and regulatory agencies to 
monitor the furnishing, billing, and/or payment of health care services 
within a specific health care/insurance industry segment.
    In addition to the nine electronic transactions specified in 
section 1173(a)(2) of the Act, section 1173(f) directs the Secretary to 
adopt standards for transferring standard data elements among health 
plans for coordination of benefits. This particular provision does not 
state that these should be standards for electronic transfer of 
standard data elements among health plans. However, we believe that the 
Congress, when writing this provision, intended for these standards to 
be an electronic form of transactions for coordination of benefits and 
sequential processing of claims. The Congress expressed its intent on 
these matters generally in section 1173(a)(1)(B) of the Act, where the 
Secretary is directed to adopt ``other financial and administrative 
transactions * * * consistent with the goals of improving the operation 
of the health care system and reducing administrative costs.''
    d. Health claim status. This transaction may be used by health care 
providers and recipients of health care products or services (or their 
authorized agents) to request the status of a health care claim or 
encounter from a health plan.
    e. Enrollment and disenrollment in a health plan. This transaction 
may be used to establish communication between the sponsor of a health 
benefit and the payer. It provides enrollment data, such as subscriber 
and dependents, employer information, and primary care health care 
provider information. A sponsor is the backer of the coverage, benefit, 
or product. A sponsor can be an employer, union, government agency, 
association, or insurance company. The health plan refers to an entity 
that pays claims, administers the insurance product or benefit, or 
both.
    f. Eligibility for a health plan. This transaction may be used to 
inquire about the eligibility, coverage, or benefits associated with a 
benefit plan, employer, plan sponsor, subscriber, or a dependent under 
the subscriber's policy. It also can be used to communicate information 
about or changes to eligibility, coverage, or benefits from information 
sources (such as insurers, sponsors, and payers) to information 
receivers (such as physicians, hospitals, third party administrators, 
and government agencies).
    g. Health plan premium payments. This transaction may be used by, 
for example, employers, employees, unions, and associations to make and 
keep track of payments of health plan premiums to their health 
insurers. This transaction may also be used by a health care provider, 
acting as liaison for the beneficiary, to make payment to a health 
insurer for coinsurance, copayments, and deductibles.
    h. Referral certification and authorization. This transaction may 
be used to transmit health care service referral information between 
health care providers, health care providers furnishing services, and 
payers. It can also be used to obtain authorization for certain health 
care services from a health plan.
    i. First report of injury. This transaction may be used to report 
information pertaining to an injury, illness, or incident to entities 
interested in the information for statistical, legal, claims, and risk 
management processing requirements.
    j. Health claims attachments. This transaction may be used to 
transmit health care service information, such as subscriber, patient, 
demographic, diagnosis, or treatment data for the purpose of a request 
for review, certification, notification, or reporting the outcome of a 
health care services review.
    k. Other transactions as the Secretary may prescribe by regulation.

[[Page 43249]]

    Under section 1173(a)(1)(B) of the Act, the Secretary may adopt 
standards, and data elements for those standards, and for other 
financial and administrative transactions deemed appropriate by the 
Secretary. These transactions would be consistent with the goals of 
improving the operation of the health care system and reducing 
administrative costs.

C. Effective Dates--General

[Please label written comments or e-mailed comments about this 
section with the subject: effective dates]

    In general, any given standard would be effective 24 months after 
the effective date (36 months for small health plans) of the final rule 
for that standard. Because there are other standards to be established 
than those in this proposed rule, we specify the date for a given 
standard under the subpart for that standard.
    Health plans would be required by part 142 to comply with our 
requirements as follows:
    1. Each health plan that is not a small plan would have to comply 
with the requirements of part 142 no later than 24 months after the 
effective date of the final rule.
    2. Each small health plan would have to comply with the 
requirements of part 142 no later than 36 months after the effective 
date of the final rule.
    Health care providers and health care clearinghouses would be 
required to begin using the standard by 24 months after the effective 
date of the final rule.

(The effective date of the final rule will be 60 days after the final 
rule is published in the Federal Register.)
    Provisions of trading partner agreements that stipulate data 
content, format definitions, or conditions that conflict with the 
adopted standard would be invalid beginning 36 months from the 
effective date of the final rule for small health plans, and 24 months 
from the effective date of the final rule for all other health plans.
    If the HHS adopts a modification to an implementation specification 
or a standard, the implementation date of the modification would be no 
earlier than the 180th day following the adoption of the modification. 
HHS would determine the actual date, taking into account the time 
needed to comply due to the nature and extent of the modification. HHS 
would be able to extend the time for compliance for small health plans. 
This provision would be at Sec. 142.106.
    Any of the health plans, health care clearinghouses, and health 
care providers may implement a given standard earlier than the date 
specified in the subpart created for that standard. We realize that 
this may create some problems temporarily, as early implementers would 
have to be able to continue using old standards until the new one must, 
by law, be in place.

D. Security Standard

[Please label written comments or e-mailed comments about this 
section with the subject: Security Standard--General]

    Section 142.308 would set forth the security standard. There is no 
recognized single standard that integrates all the components of 
security (administrative procedures, physical safeguards, technical 
security services, and technical mechanisms) that must be in place to 
preserve health information confidentiality and privacy as defined in 
the law. Therefore, we are designating a new, comprehensive standard, 
which defines the security requirements to be fulfilled.
    In fact, there are numerous security guidelines and standards in 
existence today, focusing on the different techniques available for 
implementing the various aspects of security. We thoroughly researched 
the existing guidelines and standards, and consulted extensively with 
the organizations that developed them. A list of the organizations with 
which we consulted can be found in section G. below. As a result of 
these consultations and our research, we identified several high-level 
concepts on which the standard is based:
    <bullet> The standard must be comprehensive.
    <bullet> Consultation with standards development organizations, 
such as ANSI-accredited organizations, as well as business interest 
organizations, revealed the need for a standard that addressed all 
aspects of security in a concerted fashion. The HISB noted in its 
report to the Secretary that:
    ``Comprehensive adoption of security standards in health care, not 
piecemeal implementation, is advocated to provide security to data that 
is exchanged between health care entities.
    By definition, if a system or communications between two systems, 
were implemented with technology(s) meeting standards in a general 
system security framework (Identification and Authentication; 
Authorization and Access Control; Accountability; Integrity and 
Availability; Security of Communication; and Security Administration.) 
that system would be essentially secure.
    * * * no single standards development organization (SDO) is 
addressing all aspects of health care information security and 
confidentiality, and specifically, no single SDO is developing 
standards that cover every category of the security framework.'' [Page 
189]
    <bullet> The standard must be technology-neutral.
    Our proposed standard does not reference or advocate specific 
technology because security technology is changing quickly. We want to 
give providers/plans/clearinghouses flexibility to choose their own 
technical solutions. A standard that is dependent on a specific 
technology or technologies would not be flexible enough to use future 
advances.
    <bullet> The standard must be scalable.
    The standard must be able to be implemented by all the affected 
entities, from the smallest provider to the largest clearinghouse. A 
single approach would be neither economically feasible nor effective in 
safeguarding health data. For example, in a small physician practice, a 
contingency plan for system emergencies might be only a few pages long, 
and cover issues such as where backup diskettes must be stored, and the 
location of a backup personal computer (PC). At a large health plan, 
the contingency plan might consist of multiple volumes and cover issues 
such as remote hot site operations and secure off-site storage of 
electronic media. The physician office solution would not protect the 
large plan's data, and the plan's solution would not be economically 
feasible (or necessary) for the physician office. Moreover, the statute 
specifically directed the Secretary to take into account the needs and 
capabilities of small and rural health care providers, as those terms 
are defined by the Secretary. The scalability of our approach addresses 
this direction. We are not proposing specific definitions of ``small'' 
and ``rural'' health care providers because the statute provides no 
exemptions or special benefits for these two groups. However, we 
solicit comments on the necessity to define these terms.
General Approach
    We would define the security standard as a set of requirements with 
implementation features that providers, plans, and clearinghouses must 
include in their operations to assure that electronic health 
information pertaining to an individual remains secure. The 
implementation features address specific aspects of the requirements. 
The standard does not reference or advocate specific technology. This 
would allow the security standard to be stable, yet flexible enough to 
take advantage of state-of-the-art technology.

[[Page 43250]]

The standard does not address the extent to which a particular entity 
should implement the specific features. Instead, we would require that 
each affected entity assess its own security needs and risks and 
devise, implement, and maintain appropriate security to address its 
business requirements. How individual security requirements would be 
satisfied and which technology to use would be business decisions that 
each organization would have to make.
    The recommendations contained in the National Research Council's 
1997 report For The Record: Protecting Electronic Health Information 
support our approach to the development of a security standard. This 
report presents findings and recommendations related to health data 
security, and is widely viewed as an authoritative and comprehensive 
source on the subject. The report concludes that appropriate security 
practices are highly dependent on individual circumstances, but goes on 
to suggest that:

    ``It is therefore not possible to prescribe in detail specific 
practices for all organizations; rather, each organization must 
analyze its systems, vulnerabilities, risks, and resources to 
determine optimal security measures. Nevertheless, the committee 
believes that a set of practices can be articulated in a 
sufficiently general way that they can be adopted by all health care 
organizations in one form or another.'' (Page 168)

    The specific requirements and supporting implementation features 
detailed in the next section represent this general set of practices. 
Many health care entities have already implemented some or all of these 
practices. We believe they represent those practices that are necessary 
in order to conduct business electronically in the health care industry 
today and, therefore, are normal business costs.
    Inherent in this approach is a balance between the need to secure 
health data against risk and the economic cost of doing so. Health care 
entities must consider both aspects in devising their security 
solutions.
Specific Requirements
    The proposed standard requires that each health care entity engaged 
in electronic maintenance or transmission of health information assess 
potential risks and vulnerabilities to the individual health data in 
its possession in electronic form, and develop, implement, and maintain 
appropriate security measures. Most importantly, these measures must be 
documented and kept current.
    The proposed security standard consists of the requirements that a 
health care entity must address in order to safeguard the integrity, 
confidentiality, and availability of its electronic data. It also 
describes the implementation features that must be present in order to 
satisfy each requirement. The proposed requirements and implementation 
features were developed by the implementation team based on knowledge 
of security procedures and existing standards and guidelines described 
above. This was an iterative process that involved extensive outreach 
with a number of health care industry and Department of Commerce 
security experts. We also drew upon Recommendations 1 and 3 in the 
National Research Council's 1997 report, For The Record, that were 
recommended for immediate implementation.
    ``Recommendation 1: All organizations that handle patient-
identifiable health care information--regardless of size--should adopt 
the set of technical and organizational policies, practices, and 
procedures described below to protect such information.''
    The proposed security standard addresses the following policies, 
practices, and procedures that were listed under Recommendation 1:

<bullet> Organizational Practices
    1. Security and confidentiality policies
    2. Information security officers
    3. Education and training programs, and
    4. Sanctions
<bullet> Technical Practices and Procedures
    1. Individual authentication of users
    2. Access controls
    3. Audit trails
    4. Physical security and disaster recovery
    5. Protection of remote access points
    6. Protection of external electronic communications
    7. Software discipline, and
    8. System assessment

    ``Recommendation 3: The federal government should work with 
industry to promote and encourage an informed public debate to 
determine an appropriate balance between the primary concerns of 
patients and the information needs of various users of health care 
information.''
    This proposed security standard was developed in the spirit of 
Recommendation 3. The security standard development process has been an 
open one with invitations to a number of organizations to participate 
in the security discussions. Although implementation team membership 
was limited to government employees, nongovernmental organizations; 
business organizations; individuals knowledgeable in security; and 
educational institutions have been encouraged to express their views.
    As a result of the collaborative security regulation development 
process, the implementation team has chosen to divide the proposed 
security requirements, for purposes of presentation only, into the 
following four categories:
    <bullet> Administrative procedures to guard data integrity, 
confidentiality, and availability--these are documented, formal 
practices to manage the selection and execution of security measures to 
protect data and the conduct of personnel in relation to the protection 
of data.
    <bullet> Physical safeguards to guard data integrity, 
confidentiality, and availability--these relate to the protection of 
physical computer systems and related buildings and equipment from fire 
and other natural and environmental hazards, as well as from intrusion. 
Physical safeguards also cover the use of locks, keys, and 
administrative measures used to control access to computer systems and 
facilities.
    <bullet> Technical security services to guard data integrity, 
confidentiality, and availability--these include the processes that are 
put in place to protect and to control and monitor information access, 
and
    <bullet> Technical security mechanisms--these include the processes 
that are put in place to prevent unauthorized access to data that is 
transmitted over a communications network.
    It should be noted that the only necessity is that the requirements 
would be met, not that they be presented in these four categories. 
Under this proposed rule, a business entity could choose to order the 
requirements in any manner that suits its business.
    We then determined the requirements and implementation features 
that health plans, providers, and clearinghouses would implement. The 
implementation features describe the requirements in greater detail. 
Some requirements do not require this additional level of detail. 
Within the four categories, the requirements and implementation 
features are presented in alphabetical order to ensure that no one item 
is considered to be more important than another. The relative 
importance of the requirements and implementation features would depend 
on the characteristics of each organization.
    The four categories of the matrix are described in greater detail 
in Sec. 142.308 and are depicted in tabular form along with the 
electronic signature standard in

[[Page 43251]]

a combined matrix located at Addendum 1. We have not included the 
matrix in the proposed regulation text. We invite your comments 
concerning the appropriateness and usefulness of including the matrix 
in the final regulation text. We also solicit comments as to the level 
of detail expressed in requirement implementation features; i.e., do 
any represent a level of detail that goes beyond what is necessary or 
appropriate. We have also provided a glossary of terms to facilitate a 
common understanding of the matrix entries. The glossary can be found 
at Addendum 2. Finally, we have included currently existing standards 
and guidelines mapped to the proposed security standard. This mapping 
is not all inclusive and is located at Addendum 3.
1. Administrative Procedures
[Please label written comments or e-mailed comments about this 
section with the subject: administrative procedures]

    In this proposed rule, the administrative requirements and 
supporting implementation features are presented at Sec. 142.308(a). We 
would require each to be documented. We would require the documentation 
to be made available to those individuals responsible for implementing 
the procedures and would require it to be reviewed and updated 
periodically. The following matrix depicts the requirements and 
supporting implementation features for the Administrative Procedures 
category. Following the matrix is a discussion of each of the 
requirements under that category.

------------------------------------------------------------------------

    a. Certification. Each organization would be required to evaluate 
its computer system(s) or network design(s) to certify that the 
appropriate security has been implemented. This evaluation could be 
performed internally or by an external accrediting agency.
    We are, at this time, soliciting input on appropriate mechanisms to 
permit independent assessment of compliance. We would be particularly 
interested in input from those engaging in health care electronic data 
interchange (EDI), as well as independent certification and auditing 
organizations addressing issues of documentary evidence of steps taken 
for compliance; need for, or desirability of, independent verification, 
validation, and testing of system changes; and certifications required 
for off-the-shelf products used to meet the requirements of this 
regulation.

[[Page 43252]]

    We also solicit comments on the extent to which obtaining external 
certification would create an undue burden on small or rural providers.
    b. Chain of Trust Partner Agreement. If data are processed through 
a third party, the parties would be required to enter into a chain of 
trust partner agreement. This is a contract in which the parties agree 
to electronically exchange data and to protect the transmitted data. 
The sender and receiver are required and depend upon each other to 
maintain the integrity and confidentiality of the transmitted 
information. Multiple two-party contracts may be involved in moving 
information from the originating party to the ultimate receiving party. 
For example, a provider may contract with a clearinghouse to transmit 
claims to the clearinghouse; the clearinghouse, in turn, may contract 
with another clearinghouse or with a payer for the further transmittal 
of those claims. These agreements are important so that the same level 
of security will be maintained at all links in the chain when 
information moves from one organization to another.
    c. Contingency Plan. We would require a contingency plan to be in 
effect for responding to system emergencies. The organization would be 
required to perform periodic backups of data, have available critical 
facilities for continuing operations in the event of an emergency, and 
have disaster recovery procedures in place. To satisfy the requirement, 
the plan would include the following:
    <bullet> Applications and data criticality analysis,
    <bullet> A data backup plan,
    <bullet> A disaster recovery plan,
    <bullet> An emergency mode operation plan, and
    <bullet> Testing and revision procedures.
    d. Formal Mechanism for Processing Records There would be a formal 
mechanism for processing records, that is, documented policies and 
procedures for the routine and nonroutine receipt, manipulation, 
storage, dissemination, transmission, and/or disposal of health 
information. This is important to limit the inadvertent loss or 
disclosure of secure information because of process issues.
    e. Information Access Control. An entity would be required to 
establish and maintain formal, documented policies and procedures for 
granting different levels of access to health care information. To 
satisfy this requirement, the following features would be provided:
    <bullet> Access authorization policies and procedures.
    <bullet> Access establishment policies and procedures.
    <bullet> Access modification policies and procedures.
    Access control is also discussed later in this document in the 
personnel security requirement and under the physical safeguards, 
technical security services, and technical security mechanisms 
categories.
    f. Internal Audit. There would be a requirement for an ongoing 
internal audit process, which is the in-house review of the records of 
system activity (for example, logins, file accesses, security 
incidents) maintained by an entity. This is important to enable the 
organization to identify potential security violations.
    g. Personnel Security. There would be a requirement that all 
personnel with access to health information must be authorized to do so 
after receiving appropriate clearances. This is important to prevent 
unnecessary or inadvertent access to secure information. The personnel 
security requirement would require entities to meet the following 
conditions:
    <bullet> Assure supervision of personnel performing technical 
systems maintenance activities by authorized, knowledgeable persons.
    <bullet> Maintain access authorization records.
    <bullet> Insure that operating, and in some cases, maintenance 
personnel have proper access.
    <bullet> Employ personnel clearance procedures
    <bullet> Employ personnel security policy/procedures.
    <bullet> Ensure that system users, including technical maintenance 
personnel are trained in system security.
    h. Security Configuration Management. The organization would be 
required to implement measures, practices, and procedures for the 
security of information systems. These would be coordinated and 
integrated with other system configuration management practices in 
order to create and manage system integrity. This integration process 
is important to ensure that routine changes to system hardware and/or 
software do not contribute to or create security weaknesses. This 
requirement would include the following:
    <bullet> Documentation.
    <bullet> Hardware/software installation and maintenance review and 
testing for security features.
    <bullet> Inventory procedures.
    <bullet> Security testing.
    <bullet> Virus checking.
    i. Security Incident Procedures. There would be a requirement to 
implement accurate and current security incident procedures. These are 
formal, documented instructions for reporting security breaches, so 
that security violations are reported and handled promptly. These 
instructions would include the following:
    <bullet> Report procedures.
    <bullet> Response procedures.
    j. Security Management Process. A process for security management 
would be required. This involves creating, administering, and 
overseeing policies to ensure the prevention, detection, containment, 
and correction of security breaches. We would require the organization 
to have a formal security management process in place to address the 
full range of security issues. Security management includes the 
following mandatory implementation features:
    <bullet> Risk analysis.
    <bullet> Risk management.
    <bullet> A sanction policy.
    <bullet> A security policy.
    k. Termination Procedures. There would be a requirement to 
implement termination procedures, which are formal, documented 
instructions, including appropriate security measures, for the ending 
of an employee's employment or an internal/external user's access. 
These procedures are important to prevent the possibility of 
unauthorized access to secure data by those who are no longer 
authorized to access the data. Termination procedures would include the 
following mandatory implementation features:
    <bullet> Changing combination locks.
    <bullet> Removal from access lists.
    <bullet> Removal of user account(s).
    <bullet> Turn in of keys, tokens, or cards that allow access.
    1. Training. This proposed rule would require security training for 
all staff regarding the vulnerabilities of the health information in an 
entity's possession and procedures which must be followed to ensure the 
protection of that information. This is important because employees 
need to understand their security responsibilities and make security a 
part of their day-to-day activities. The implementation features that 
would be required to be incorporated follow:
    <bullet> Awareness training for all personnel, including 
management, (this is also included as a requirement under physical 
safeguards).
    <bullet> Periodic security reminders.
    <bullet> User education concerning virus protection.
    <bullet> User education in importance of monitoring login success/
failure, and how to report discrepancies.
    <bullet> User education in password management.

2. Physical Safeguards To Guard Data Integrity, Confidentiality, and 
Availability
[Please label written comments or e-mailed comments about this 
section with the subject: Physical Safeguards]

    The requirements and implementation features for physical 
safeguards are presented at Sec. 142.308(b) of this proposed rule. We 
would require each of these safeguards to be documented. We would 
require this documentation to be made available to those individuals 
responsible for implementing the safeguards and to be reviewed and 
updated periodically. The following matrix depicts the requirements and 
implementation features for the Physical Safeguards category. Following 
the matrix is a discussion of each of the requirements under that 
category.

------------------------------------------------------------------------

    a. Assigned Security Responsibility. We would require the security 
responsibility to be assigned to a specific individual or organization, 
and the assignment be documented. These responsibilities would include 
the management and supervision of (1) the use of security measures to 
protect data, and (2) the conduct of personnel in relation to the 
protection of data. This assignment is important to provide an 
organizational focus and importance to security and to pinpoint 
responsibility.
    b. Media Controls. Media controls would be required in the form of 
formal, documented policies and procedures that govern the receipt and 
removal of hardware/software (for example, diskettes, tapes) into and 
out of a facility. They are important to ensure total control of media 
containing health information. These controls would include the 
following mandatory implementation features:
    <bullet> Controlled access to media.
    <bullet> Accountability (tracking mechanism).
    <bullet> Data backup.
    <bullet> Data storage.
    <bullet> Disposal.
    c. Physical Access Controls. Physical access controls (limited 
access) would be required. These would be formal, documented policies 
and procedures for limiting physical access to an entity while ensuring 
that properly authorized access is allowed. These controls would be 
extremely important to the security of health information by preventing 
unauthorized physical access to information and ensuring that 
authorized personnel have proper access. These controls would include 
the following mandatory implementation features:
    <bullet> Disaster recovery.
    <bullet> Emergency mode operation.
    <bullet> Equipment control (into and out of site).
    <bullet> A facility security plan.
    <bullet> Procedures for verifying access authorizations prior to 
physical access.
    <bullet> Maintenance records.
    <bullet> Need-to-know procedures for personnel access.
    <bullet> Sign-in for visitors and escort, if appropriate.
    <bullet> Testing and revision.
    d. Policy/Guideline on Workstation Use. Each organization would be 
required to have a policy/guideline on workstation use. These 
documented instructions/procedures would delineate the proper functions 
to be performed and the manner in which those functions are to be 
performed (for example, logging off before leaving a terminal 
unattended). This would be important so that employees will understand 
the manner in which workstations must be used to maximize the security 
of health information.
    e. Secure Workstation Location. Each organization would be required 
to put in place physical safeguards to eliminate or minimize the 
possibility of unauthorized access to information. This would be 
important especially in public buildings, provider locations, and in 
areas where there is heavy pedestrian traffic.
    f. Security Awareness Training. Security awareness training would 
be required for all employees, agents, and contractors. This would be 
important because employees would need to understand their security 
responsibilities based on their job responsibilities in the 
organization and make security a part of their daily activities.
3. Technical Security Services To Guard Data Integrity, 
Confidentiality, and Availability
[Please label written comments or e-mailed comments about this 
section with the subject: Technical Security Services]

    The proposed requirements and implementation features for technical 
security services are presented at Sec. 142.308(c). We would require 
each of these services to be implemented and documented. The 
documentation would be made available to those individuals responsible 
for implementing the services and would be reviewed and updated 
periodically. The following matrix depicts the requirements and 
implementation features for the Technical Security Services category.

------------------------------------------------------------------------

    a. Access Control. There would be a requirement for access control 
which would restrict access to resources and allow access only by 
privileged entities. It would be important to limit access to health 
information to those employees who have a business need to access it. 
Types of access control include, among others, mandatory access 
control, discretionary access control, time-of-day, classification, and 
subject-object separation. The following implementation feature would 
be used:
    <bullet> Procedure for emergency access.
    In addition, at least one of the following three implementation 
features would be used:
    <bullet> Context-based access.
    <bullet> Role-based access.
    <bullet> User-based access.
    The use of the encryption implementation feature would be optional.
    b. Audit Controls. Each organization would be required to put in 
place audit control mechanisms to record and examine system activity. 
They would be important so that the organization can identify suspect 
data access activities, assess its security program, and respond to 
potential weaknesses.
    c. Authorization Control. There would be a requirement to put in 
place a mechanism for obtaining consent for the use and disclosure of 
health information. These controls would be necessary to ensure that 
health information is used only by properly authorized individuals. 
Either of the following implementation features may be used:
    <bullet> Role-based access.
    <bullet> User-based access (see access control, above.).
    d. Data Authentication. Each organization would be required to be 
able to provide corroboration that data in its possession has not been 
altered or destroyed in an unauthorized manner. Examples of how data 
corroboration may be assured include the use of a check sum, double 
keying, a message authentication code, or digital signature.
    e. Entity Authentication. Each organization would be required to 
implement entity authentication, which is the corroboration that an 
entity is who it claims to be. Authentication would be important to 
prevent the improper identification of an entity who is accessing 
secure data. The following implementation features would be used:
    <bullet> Automatic log off.
    <bullet> Unique user identification.
    In addition, at least one of the following implementation features 
would be used:
    <bullet> A biometric identification system.
    <bullet> A password system.
    <bullet> A personal identification number (PIN).
    <bullet> Telephone callback.
    <bullet> A token system which uses a physical device for user 
identification.
4. Technical Security Mechanisms To Guard Against Unauthorized Access 
to Data That Is Transmitted Over a Communications Network
[Please label written comments or e-mailed comments about this 
section with the subject: Technical Security Mechanisms]

    In this proposed rule, the requirements and implementation features 
for technical security mechanisms are presented at Sec. 142.308(d). 
Each of these mechanisms would need to be documented. The documentation 
would be made available to those individuals responsible for 
implementing the mechanisms and would be reviewed and updated 
periodically. The following matrix depicts the requirement and 
implementation features for the Technical Security Mechanisms category. 
Following the matrix is a discussion of the requirement under that 
category.

------------------------------------------------------------------------

    Each organization that uses communications or networks would be 
required to protect communications containing health information that 
are transmitted electronically over open networks so that they cannot 
be easily intercepted and interpreted by parties other than the 
intended recipient, and to protect their information systems from 
intruders trying to access systems through external communication 
points. When using open networks, some form of encryption should be 
employed. The utilization of less open systems/networks such as those 
provided by a value-added network (VAN) or private-wire arrangement 
provides sufficient access controls to allow encryption to be an 
optional feature. These controls would be important because of the 
potential for compromise of information over open systems such as the 
Internet or dial-in lines.
    The following implementation features would be in place:
    <bullet> Integrity controls.
    <bullet> Message authentication.
    One of the following implementation features would be in place:
    <bullet> Access controls.
    <bullet> Encryption.
    In addition, if using a network for communications, the following 
implementation features would be in place:
    <bullet> Alarm.
    <bullet> Audit trail.
    <bullet> Entity authentication.
    <bullet> Event reporting.
    Small or Rural Provider Example. The size and organizational 
structure of the entities that would be required to implement this 
standard vary tremendously. Therefore, it would be impossible to 
provide examples that would cover every possible implementation of 
security in the health care industry. Nevertheless, we have included an 
example describing the manner in which a small or rural provider might 
choose to implement the requirements of the standard. (For purposes of 
this example, we would describe a small or rural provider as a one to 
four physician office, with two to five additional employees. The 
office uses a PC-based practice management system, which is used to 
communicate intermittently with a clearinghouse for submission of 
electronic claims. The number of providers is of less importance for 
this example than the relatively simple technology in use and the fact 
that there is insufficient volume or revenue to justify employment of a 
computer system administrator.) We want to emphasize that there are 
numerous ways in which an entity could implement these requirements and 
features. This example does not necessarily represent the best way or 
the only way in which an entity could choose to implement security.
    We anticipate that the small or rural provider office, as described 
above, would normally evaluate and self-certify that the appropriate 
security is in place for its computer system and office procedures. 
This evaluation could be done by a knowledgeable person on the staff, 
or more likely, by a consultant or by the vendor of the practice 
management system as a service to its customers. First, the office 
might assess actual and potential risks to its information assets. 
Then, to establish appropriate security, the office would develop 
policies and procedures to mitigate and manage those risks. These would 
include an overall framework outlining information security activities 
and responsibilities, and repercussions for failure to meet those 
responsibilities.
    Next, this office might develop contingency plans to reduce or 
negate the damage resulting from processing anomalies; for example, 
establish a routine process for maintaining back up floppy disks at a 
second location, obtain a PC maintenance contract, and arrange for use 
of a backup PC should the need arise. This office would need to 
periodically review its plan to determine whether it still met the 
office's needs.
    The office would need to create and document a personnel security 
policy and procedures to be followed. A key individual on the office 
staff should be charged with the responsibility for assuring the 
Personnel Security requirement is met. This responsibility would 
include seeing that the access authorization levels granted are 
documented and kept current (for example, records are kept of everyone 
who is permitted to use the PC and what files they may access), and 
training all personnel in security. Again, we emphasize that these 
requirements are scalable. The requirement for Personnel Clearance 
Procedures could be met in a small office with standard personal and 
professional reference checks, while a large organization may employ 
more formal, rigorous background investigations.
    This same individual could also be charged with the responsibility 
for Security Configuration Management and Termination Procedures. For 
our small provider, the Security Configuration Management requirement 
would be relatively easy to satisfy; the necessary features could be 
part of a purchased hardware/software package (for example, a new PC 
might be equipped with virus checking software), or included as part of 
the support supplied with the purchase of equipment and software. 
Termination procedures would incorporate specific security actions to 
be taken as a result of an employee's termination, such as obtaining 
all keys and changing combinations or passwords. A ``position 
description'' document describing this person's duties could specify 
the level of detail necessary.
    The small or rural provider office would also need to ensure that 
they have activated the internal auditing capability of the software 
used to manage health data files so that it tracks who has accessed the 
data. (We expect that the capability of keeping audit trails will 
become standard in all health care software in the near future, spurred 
on by the health information privacy debates in the Congress and 
elsewhere.)
    A small or rural provider may document compliance with many of the

[[Page 43256]]

foregoing administrative security requirements by including them in an 
``office procedures'' type of document that should be required reading 
by new employees and always available for reference. Requirements that 
would lend themselves to inclusion in an ``office procedures'' document 
include: contingency plans, formal records processing procedures, 
information access controls (rules for granting access, actual 
establishment of access, and procedures for modifying such access), 
security incident procedures (for example, who is to be notified if it 
appears that medical information has been accessed by an unauthorized 
party), and training. Periodic security reminders could include visual 
aids, such as posters and screen savers, and oral reminders in 
recurring meetings.
    Physical Access controls would be relatively straightforward for 
this small or rural office, using locked rooms and/or closets to secure 
equipment and media from unauthorized access. The ``office procedures/
policies'' manual should include directions for authorizing access and 
keeping records of authorized accesses. Media Controls and Workstation 
Use policy instructions would be developed by the office and would 
include additional instructions on such items as where to store backed-
up data, how to dispose of data no longer needed, or logging off when 
leaving terminals unattended.
    Safeguards for the security of workstation location(s) would depend 
upon the physical surroundings in the small or rural office. Our small 
or rural provider may meet the requirements by locating equipment in 
areas that are generally populated by office staff and have some degree 
of physical separation from the public. Security Awareness Training 
would be part of the new employee orientation process and would be a 
periodic recurring discussion item in staff meetings.
    The Technical Security Services requirements for Access Control, 
Entity Authentication, and Authorization Control may be achieved simply 
by implementing a user-based data access model (assigning a user-name 
and password combination to each authorized employee). Other access 
models could be employed if desired, but would prove unwieldy for the 
small office. For example, the role-based access process groups users 
with similar data access needs, and context-based access is based upon 
the context of a transaction--not on the attributes of the initiator. 
By assigning full access rights to a minimum of two key individuals in 
the office, implementation of the Emergency Access feature could be 
satisfied. Audit control mechanisms, by necessity, would be provided by 
software featuring that capability. By establishing and using a message 
authentication code, Data Authentication would be achieved. Use of the 
password system mentioned above could also satisfy the Unique User 
Identification requirement.
    As our example provider contracts with a third party to handle 
claims processing, the claims processing contract would be the vehicle 
to provide for a chain of trust (requiring the contractor to implement 
the same security requirements and take responsibility for protecting 
the data it receives).
    If this provider chooses to use the Internet to transmit or receive 
health information, some form of encryption must be used. For example, 
the provider could procure and use commercial software to provide 
protection against unauthorized access to the data transmitted or 
received. (This decision must take into account what encryption system 
the message recipient uses.) On the other hand, health information when 
transmitted via other means such as VANs, private wires, or even dial-
up connections may not require such absolute protection as is provided 
by encryption. This small or rural provider would likely not be part of 
a network configuration, therefore, only integrity controls and message 
authentication would be required and could be provided by currently 
available software products, most likely provided as part of their 
contract with their health care clearinghouse.
    Small providers may need guidance regarding the content of the 
documents required by this rule (for example, specifics of a chain of 
trust partner agreement). We would expect models of the documentation 
discussed in this example to be developed by industry associations and 
vendors. If this model documentation is not developed, DHHS would work 
with the industry to develop them.

E. Electronic Signature Standard

[Please label written comments or e-mailed comments about this 
section with the subject: Electronic Signature Standard]

    HIPAA directs the Secretary of the Department of Health and Human 
Services to coordinate with the Secretary of the Department of Commerce 
in adopting standards for the electronic transmission and 
authentication of signatures with respect to the transactions referred 
to in the law. This rule was developed in coordination with the 
Department of Commerce's National Institute of Standards and 
Technology. We propose to adopt a cryptographically based digital 
signature as the standard.
    Whenever a HIPAA specified transaction requires the use of an 
electronic signature, the standard must be used. It should be noted 
that an electronic signature is not required for any of the currently 
proposed standard transactions.
    In the electronic environment, the same legal weight associated 
with an original signature on a paper document may be needed for 
electronic data. Use of an electronic signature refers to the act of 
attaching a signature by electronic means. The electronic signature 
process involves authentication of the signer's identity, a signature 
process according to system design and software instructions, binding 
of the signature to the document and non-alterability after the 
signature has been affixed to the document. The generation of 
electronic signatures requires the successful identification and 
authentication of the signer at the time of the signature.
    The proposed standard for electronic signature is presented at 
Sec. 142.310 and would be digital.
    The following matrix depicts the requirement and implementation 
features for electronic signatures. Following the matrix is a 
discussion of the electronic signature requirement.

[[Page 43257]]

                                         Nonrepudiation.                
                                         Transportability.              
                                         User authentication.           
------------------------------------------------------------------------

    Various technologies may fulfill one or more of the requirements 
specified in the matrix. Authentication systems (passwords, biometrics, 
physical feature authentication, behavioral actions and token-based 
authentication) can be combined with cryptographic techniques to form 
an electronic signature. However, a complete electronic signature 
system may require more than one of the technologies mentioned above. 
If electronic signatures would be used, certain implementation features 
must be included, specifically:
    <bullet> Message integrity.
    <bullet> Nonrepudiation.
    <bullet> User authentication.
    Currently there are no technically mature techniques that provide 
the security service of nonrepudiation in an open network environment, 
in the absence of trusted third parties, other than digital signature-
based techniques. Therefore, if electronic signatures are employed, we 
would require that digital signature technology be used. A digital 
signature is formed by applying a mathematical function to the 
electronic document. This process yields a unique bit string, referred 
to as a message digest. The digest (only) is encrypted using the 
originator's private key and the resulting bit stream is appended to 
the electronic document. The recipient of the transmitted document 
decrypts the message digest with the originator's public key, applies 
the same message hash function to the document, then compares the 
resulting digest with the transmitted version. If they are identical, 
then the recipient is assured that the message is unaltered and the 
identity of the signer is proven. Since only the signatory authority 
can hold the Private Key used to digitally sign the document, the 
critical feature of nonrepudiation is enforced. Other electronic 
signature implementation features that may be used follow:
    <bullet> Ability to add attributes.
    <bullet> Continuity of signature capability.
    <bullet> Countersignatures capability.
    <bullet> Independent verifiability.
    <bullet> Interoperability.
    <bullet> Multiple signatures.
    <bullet> Transportability.
    This standard is described in greater detail in Sec. 142.310 of the 
regulation text and is depicted in tabular form along with the security 
standard in a combined matrix located at Addendum 1. We have not 
included the matrix in the proposed regulation text. We invite your 
comments concerning the appropriateness and usefulness of including the 
matrix in the final regulation text. We have also provided a glossary 
of terms to facilitate a common understanding of the matrix entries. 
The glossary can be found at Addendum 2. Finally, we have included 
currently existing standards and guidelines mapped to the proposed 
electronic signature standard. This mapping is not all inclusive and is 
located at Addendum 3.

F. Selection Criteria

    Each individual implementation team weighted the criteria described 
in section I.B. above, Process for Developing National Standards, in 
terms of the standard it was addressing. As we assessed security and 
electronic signatures, it became apparent that while the security 
standard set forth in Sec. 142.308 and the electronic signature 
standard set forth in Sec. 142.310 satisfy all the criteria described 
above, they most strongly address criteria 1, 3, 7, 9, and 10. These 
criteria are described below in the specific context of these 
standards.
    1. Improve the efficiency and effectiveness of the health care 
system.
    The security and electronic signature standards would be integrated 
with the electronic transmission of health care information to improve 
the overall effectiveness of the health care system. This integration 
would assure that electronic health care information would not be 
accessible to any unauthorized person or organization, but would be 
both accurate and available to those who are authorized to receive it.
    3. Be consistent and uniform with the other HIPAA standards and, 
secondly, with other private and public sector health data standards.
    The security and electronic signature standards were developed 
after a comprehensive review of existing standards and guidelines, with 
significant input by a wide range of industry experts. As indicated in 
Addendum 3, the standards map well to existing standards and 
guidelines.
    7. Be technologically independent of computer platforms and 
transmission protocols.
    We have defined the security and electronic signature standards in 
terms of requirements that would allow businesses in the health care 
industry to select the technology that best meets their business 
requirements while still allowing them to comply with the standards.
    9. Keep data collection and paperwork burdens on users as low as is 
feasible.
    The security and electronic signature standards would allow 
individual health care industry businesses to ascertain the level of 
security information that would be needed. The confidentiality level 
associated with individual data elements concerning health care 
information would determine the appropriate security application to be 
used. The security standard would define the requirements to be met to 
achieve the privacy and confidentiality goal, but each business entity, 
driven by its business requirements, would decide what techniques and 
controls would provide appropriate and adequate electronic data 
protection. This would allow data collection and the paperwork burden 
to be as low as is feasible.
    10. Incorporate flexibility to adapt more easily to changes in the 
health care infrastructure and information technology.
    A technologically neutral security standard would be more adaptable 
to changes in infrastructure and information technology.

[[Page 43258]]

G. Consultations

    In the development of the security and electronic signature 
standards, we consulted with many organizations, including those the 
legislation requires (section 1172(c)(3)(B) of the Act):
    1. The NCVHS held two days of public hearings on security issues in 
August 1997, and made a recommendation to the Secretary of HHS, as 
required by the legislation. The NCVHS recommendation to the Secretary 
of HHS, as required by the legislation, was for a technologically 
neutral standard. It identified certain criteria to be established for 
a health information system to be secure. The proposed security 
standard complies with the NCVHS security recommendation.
    2. The ANSI Accredited Standards Committee (ASC) X12 subcommittees 
on communication and control, insurance and government were contacted. 
Their current standards development effort is focused on messaging 
rather than on security requirements.
    3. American Society for Testing and Materials (ASTM), Committee E31 
on Computerized Systems participated in the security discussions.
    4. Association for Electronic Health Care Transactions (AFEHCT), 
the clearinghouse organization, provided information on its health care 
transaction process requirements and emphasized that the security 
standard must be adaptable to different business needs.
    5. Computer-based Patient Record Institute (CPRI) was consulted 
because the Work Group on Confidentiality, Privacy and Security is 
working on the establishment of guidelines, confidentiality agreements, 
security requirements, and frameworks. CPRI works closely with 
accredited standards development organizations.
    6. Health Level Seven (HL-7) has been contacted through its 
participation at the HISB meetings.
    7. NUCC and the NUBC were apprised of the different implementation 
teams' efforts. NUBC has not addressed security issues at any of the 
public meetings. NUCC identified a number of issues at its November 18-
19 meeting and provided written comments to us.

H. Rules for Security Standards and Electronic Signature Standard

    1. Health Plans
    a. In Sec. 142.306(a), we would require health plans to accept and 
apply the security standard to all health care information pertaining 
to an individual that is electronically maintained or electronically 
transmitted. Federal agencies and States may place additional 
requirements on their health plans. In addition, trading partners may 
mutually agree to implement additional security measures.
    b. In Sec. 142.310(a), entities would not be required to use an 
electronic signature. However, if a plan elects to use an electronic 
signature in one of the transactions named in the law, it would be 
required to apply the electronic signature standard described in 
Sec. 142.310(b) to that transaction. In the future, we anticipate that 
the standards for other transactions may include requirements for 
signatures. In particular, the proposed standard for claims 
attachments, which will be issued in a separate regulations package 
later, may include signature requirements on some or all of the 
attachments. If the proposed attachments standard includes such 
signature requirements, we will address the issue of how to reconcile 
such requirements with existing State and Federal requirements for 
written signatures as part of the proposed rule.
2. Health Care Clearinghouses
    a. We would require in Sec. 142.306(b) that each health care 
clearinghouse comply with the security standard to ensure all health 
care information and activities are protected from unauthorized access. 
If the clearinghouse is part of a larger organization, then security 
must be imposed to prevent unauthorized access by the larger 
organization. The security standards apply to all health information 
pertaining to an individual that is electronically maintained or 
electronically transmitted.
    b. In Sec. 142.310(a), entities would not be required to use an 
electronic signature. However, if a plan elects to use an electronic 
signature in one of the transactions named in the law, it would be 
required to apply the electronic signature standard described in 
Sec. 142.310(b) to that transaction. In the future, we anticipate that 
the standards for other transactions may include requirements for 
signatures. In particular, the proposed standard for claims 
attachments, which will be issued in a separate regulations package 
later, may include signature requirements on some or all of the 
attachments. If the proposed attachments standard includes such 
signature requirements, we will address the issue of how to reconcile 
such requirements with existing State and Federal requirements for 
written signatures as part of the proposed rule.
3. Health Care Providers
    a. In Sec. 142.306(a), we would require each health care provider 
to apply the security standard to all health information pertaining to 
an individual that is electronically maintained or electronically 
transmitted.
    b. In Sec. 142.310(a), entities would not be required to use an 
electronic signature. However, if a plan elects to use an electronic 
signature in one of the transactions named in the law, it would be 
required to apply the electronic signature standard described in 
Sec. 142.310(b) to that transaction. In the future, we anticipate that 
the standards for other transactions may include requirements for 
signatures. In particular, the proposed standard for claims 
attachments, which will be issued in a separate regulations package 
later, may include signature requirements on some or all of the 
attachments. If the proposed attachments standard includes such 
signature requirements, we will address the issue of how to reconcile 
such requirements with existing State and Federal requirements for 
written signatures as part of the proposed rule.

I. Effective Dates

    Health plans would be required to comply with the security and 
electronic signature standards as follows:
    1. Each health plan that is not a small health plan would have to 
comply with the requirements of Secs. 142.306, 142.308, and 142.310 no 
later than 24 months after publication of the final rule.
    2. Each small health plan would have to comply with the 
requirements of Secs. 142.306, 142.308, and 142.310 no later than 36 
months after the date of publication of the final rule.
    3. If the effective date for the electronic transaction standards 
is later than the effective date for the security standard, 
implementation of the security standard would not be delayed until the 
standard transactions are in use. The security standard would still be 
effective with respect to electronically stored or maintained data. 
Security of health information would not be solely tied to the standard 
transactions but would apply to all individual health information 
electronically stored, maintained, or transmitted.
    4. Under this proposed rule, in some cases, a health plan could 
choose to convert from paper to standard EDI transactions prior to the 
effective date of the security standard. We would recommend that the 
security standard be implemented at that time in order to safeguard the 
data in those transactions. We invite comments on this issue.

[[Page 43259]]

    Failure to comply with standards may result in monetary penalties. 
The Secretary is required by statute to impose penalties of not more 
than $100 per violation on any person who fails to comply with a 
standard, except that the total amount imposed on any one person in 
each calendar year may not exceed $25,000 for violations of one 
requirement.
    We are not proposing any enforcement procedures at this time, but 
we plan to do so in a future Federal Register document once the 
industry has some experience with using the standards. These procedures 
will be in place by the time the standards are implemented by industry. 
We envision the monitoring and enforcement process as a partnership 
between the Federal government and the private sector. Some private 
accreditation bodies have already exhibited interest in certifying 
compliance with the security requirements as part of their 
accreditation reviews. Small providers may be able to self-certify 
through industry-developed checklists. HHS would likely retain the 
final responsibility for determining violations and imposing the 
penalties specified by the statute. We welcome comments on this 
approach.

III. Implementation

    If an entity elects to use an electronic signature in a 
transaction, or if an electronic signature is required by a transaction 
standard adopted by the Secretary, the entity must apply the electronic 
signature standard described in Sec. 142.310(b).
    How the security standard would be implemented is dependent upon 
industry trading partner agreements for electronic transmissions. The 
health care industry would be able to adapt the security matrix to meet 
its business needs. We propose that the requirements of the security 
standard be implemented over time. However, we would require 
implementation to be complete by the applicable effective date. We 
would encourage, but not require that entities comply with the security 
standard as soon as practicable, preferably before implementing the 
transactions standards.
    The security standard would supersede contrary provisions of State 
law including State law requiring medical or health plan records to be 
maintained or transmitted in other electronic formats. There are 
certain exceptions when the standards would not supersede contrary 
provisions of State law; section 1178 identifies those conditions and 
directs the Secretary to determine whether a particular State provision 
falls within one or more of the exceptions.
    The electronic signature standard (digital signature) would be 
deemed to satisfy Federal and State statutory requirements for written 
signatures with respect to the named transactions referred to in the 
legislation.
    Several accreditation organizations such as the Electronic 
Healthcare Network Accreditation Commission (EHNAC), the Joint 
Commission on Accreditation of Healthcare Organizations (JCAHO), and 
the National Committee for Quality Assurance (NCQA), indicate that one 
of their accreditation requirements will be compliance with the HIPAA 
security and electronic signature (if applicable) standards.

IV. New and Revised Standards

    To encourage innovation and promote development, we plan to 
establish a process to allow an organization to request a revision or 
replacement to any adopted standard or standards. An organization could 
request a revision or replacement to an adopted standard by requesting 
a waiver from the Secretary of Health and Human Services to test a 
revised or new standard. The organization would be required, at a 
minimum, to demonstrate that the revised or new standard offers a clear 
improvement over the adopted standard. If the organization presents 
sufficient documentation that supports testing of a revised or new 
standard, we want to be able to grant the organization a temporary 
waiver to test while remaining in compliance with the law. We do not 
intend to establish a process that would allow an organization to avoid 
using any adopted standard.
    We would welcome comments on the following: (1) How we should 
establish this process, (2) the length of time a proposed standard 
should be tested before we decide whether to adopt it, (3) whether we 
should solicit public comments before implementing a change in a 
standard, and (4) other issues and recommendations we should consider. 
Comments should be submitted to the addresses presented in the 
ADDRESSES section of this document.
    The following is one possible process:
    <bullet> Any organization that wishes to revise or replace an 
adopted standard would submit its waiver request to an HHS evaluation 
committee (to be established or defined). The organization would do the 
following for each standard it wishes to revise or replace:
    + Provide a detailed explanation, no more than 10 pages, of how the 
revision or replacement would be a clear improvement over the current 
standard.
    + Provide specifications and technical capabilities on the revised 
or new standard, including any additional system requirements.
    + Provide an explanation, no more than five pages, of how the 
organization intends to test the standard.
    <bullet> The committee's evaluation would, at a minimum, be based 
on the following:
    + A cost-benefit analysis.
    + An assessment of whether the proposed revision or replacement 
demonstrates a clear improvement to an existing standard.
    + The extent and length of time of the waiver.
    <bullet> The evaluation comm
