ACTION: Final rule.


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


SUMMARY: This final rule revises and responds to comments on certain 
laboratory requirements issued pursuant to the Clinical Laboratory 
Improvement Amendments of 1988 (CLIA), Pub. L. 100-578. Specifically, 
this final rule sets forth requirements for certain quality control 
(QC) provisions and personnel qualifications; consolidates and 
reorganizes the requirements for patient test management, QC, and 
quality assurance; and changes the consensus required for grading 
proficiency testing challenges.
    To ensure a smooth transition to the new provisions for directors 
of high complexity testing who are not board certified (but who have 
doctoral degrees), we will not be holding facilities out of compliance 
with the provisions of the rule concerning directors who are not board 
certified until the effective date of this new rule, to the extent the 
facilities are otherwise in compliance with the requirements for 
laboratory directors.


EFFECTIVE DATES: This final rule is effective on April 24, 2003, except 
Sec.  493.1443(b)(3) is effective on February 24, 2003.
    Compliance Dates: To ensure a clear transition from the board 
certification provisions of the former rule at 42 CFR 493.1443(b)(2) 
that have a compliance date of December 31, 2002 (as set forth in 65 FR 
82941), we will not be holding facilities out of compliance with the 
former rule until the effective date of the parallel provisions of this 
new rule to the extent that facilities are otherwise in compliance with 
the regulations for laboratory directors.

I. Background


    On February 28, 1992, we published a final rule with comment period 
in the Federal Register (57 FR 7002) that set forth the requirements 
for laboratories that are subject to the Clinical Laboratory 
Improvement Amendments of 1988 (CLIA).
    Under the provisions of the sentence following section 1861(s)(15) 
through 1861(s)(17) of the Social Security Act, (the Act) any 
laboratory that wants to be paid for services furnished to Medicare 
beneficiaries must meet the requirements of section 353 of the Public 
Health Services Act. Subject to specified exceptions, all laboratories, 
regardless of whether they receive payment from the Medicare or 
Medicaid programs must have a current and valid CLIA certificate to 
test human specimens. The February 28, 1992 final rule with comment 
period established uniform requirements based on the complexity of 
testing performed by laboratories regardless of the laboratory's 
location, size, or type. In the interest of public health, we included 
requirements in the February 28, 1992 final rule with comment period to 
ensure the quality of laboratory services.
    We recognized that it would take time and resources for 
laboratories to understand and to implement the new requirements 
contained in the February 28, 1992 final rule with comment period. This 
final rule completes the phase-in of certain requirements where the 
comments supported taking this action.
    The phased-in provision included quality control (QC) requirements 
applicable to moderate complexity tests and the date by which an 
individual with a doctorial degree must possess board certification to 
qualify as a director of a laboratory that performs high complexity 
testing.
    During the phase-in, the Food and Drug Administration (FDA) was to 
establish a process to review and clear manufacturers' QC instructions 
for CLIA QC purposes. Because the CLIA program is user fee funded, we 
decided it would be prudent to wait until the phase-in period ended 
before implementing the FDA QC review. This afforded us the survey 
experience necessary to determine whether an additional FDA review 
process beyond that already in place as part of the premarket review 
would be of benefit to laboratories. We realized through our experience 
inspecting laboratories that an additional FDA review would not be of 
such benefit. We decided to remove this prospective provision. 
Therefore, we are removing all references to the FDA CLIA QC clearance 
process that was not implemented.
    The phase-in effective dates contained in the February 28, 1992 
final rule with comment period were further extended in the final rules 
with comment period published on December 6, 1994 in the Federal 
Register (59 FR 62606), May 12, 1997 in the Federal Register (62 FR 
25855), October 14, 1998 in the Federal Register (63 FR 55031), and 
December 29, 2000 in the Federal Register (65 FR 82941).
    The extensions allowed previously unregulated laboratories time to 
understand and implement these requirements. The extensions also 
provided the Department of Health and Human Services (HHS) additional 
time to issue revised QC requirements, review board certification 
program requests for approval, and ensure that laboratory directors 
with a doctoral degree had sufficient time to successfully complete the 
requirements for board certification.
    On December 28, 2001, we published a proposed rule in the Federal 
Register (66 FR 67163) seeking comments on provisions to revise and 
expand the qualification requirements by which an individual with a 
doctoral degree in a chemical, physical, biological, or clinical 
laboratory science from an accredited institution may qualify to serve 
as a director of a laboratory performing high complexity testing. The


[[Page 3641]]


three proposed alternative qualification pathways were as follows:
    [sbull] On or after January 1, 2003, be certified and continue to 
be certified by a board approved by HHS.
    [sbull] Before January 1, 2003, must have served or be serving as a 
director of a laboratory performing high complexity testing and must 
have at least 2 years of laboratory training or experience, or both; 
and 2 years experience directing or supervising high complexity 
testing.
    [sbull] Have at least 6 years of laboratory training or experience, 
or both, including 2 years of experience directing or supervising high 
complexity testing.
    In this final rule, effective April 24, 2003, all laboratories must 
meet and follow the QC requirements. In addition, we are setting forth 
qualification requirements for an individual with a doctoral degree to 
serve as a director of a laboratory performing high complexity testing. 
Effective February 24, 2003, an individual with a doctoral degree may 
qualify to serve as a director of a laboratory that performs high 
complexity testing if he or she is certified and continues to be 
certified by a board approved by HHS; or before the effective date of 
this rule, has served or is serving as a director of a laboratory 
performing high complexity testing and has acquired at least 2 years of 
laboratory training or experience, or both, and 2 years of experience 
directing or supervising high complexity testing.
    The qualification requirements for high complexity laboratory 
directors that are contained in this final rule will become effective 
February 24, 2003. To ensure a smooth transition to these new 
provisions, we will not be holding facilities out of compliance with 
the Board certified regulations of the former rule until the effective 
date of this new rule, to the extent the facilities are otherwise in 
compliance with the regulations for laboratory directors.
    In addition, we are addressing the comments received in response to 
the February 28, 1992 final rule with comment period concerning part 
493 of title 42 of the Code of Federal Regulations (CFR), subparts I, 
J, K, M, and P; comments received in response to the date-extension 
rules for certain provisions of subparts K and M; and comments to the 
December 28, 2001 proposed rule regarding qualification requirements 
for directors of laboratories performing high complexity testing.


II. Highlights and Organization of Final Rule


    This regulation contains revisions to part 493 of title 42 of the 
CFR. We have renamed, reorganized, and consolidated similar 
requirements into one section, deleted duplicate requirements, and 
reworded numerous requirements to maintain and/or clarify their 
original intent, making the revised regulation easier to read and 
understand. In addition to specific changes to subparts I, J, K, M, and 
P, applicable technical and conforming changes were also made to other 
subparts.
    The organization of this regulation now reflects the flow of a 
patient specimen through the laboratory, that is, from receipt of the 
specimen with the test request through test performance and test result 
reporting. In addition, this final rule more accurately describes the 
testing requirements and laboratory assessment activities.
    In this final rule, the former Subpart I--Proficiency Testing 
Programs for Tests of Moderate Complexity (Including the Subcategory), 
High Complexity, or Any Combination of These Tests has been renamed 
Proficiency Testing Programs for Nonwaived Testing. In addition, in 
each specialty and subspecialty area of the subpart, we are restoring 
the requirement for the 80 percent agreement used by proficiency 
testing programs prior to the February 28, 1992 final rule with comment 
period.
    The requirements formerly in Subpart J--Patient Test Management for 
Moderate Complexity (Including the Subcategory), High Complexity, or 
Any Combination of These Tests; Subpart K--Quality Control for Tests of 
Moderate Complexity (Including the Subcategory), High Complexity, or 
Any Combination of These Tests; and Subpart P--Quality Assurance for 
Moderate Complexity (Including the Subcategory) or High Complexity 
Testing, or Any Combination of These Tests, are consolidated and 
reorganized into a new Subpart J--Facility Administration for Nonwaived 
Testing, and Subpart K--Quality Systems for Nonwaived Testing.
    As revised by this issuance, subpart J consolidates and clarifies 
the facility administration requirements for laboratories performing 
nonwaived testing. These include requirements for facility space, 
utilities and safety, transfusion services, and record and specimen 
retention. Also, subpart J now specifies that laboratories must comply 
with Federal, State, and local laboratory requirements. This will allow 
CMS to support a Federal, State, or local government that seeks to 
protect the public from actions it finds would be detrimental to public 
health. In addition, the requirements formerly at Sec.  493.1111 (now 
at Sec.  493.1242(c)) have been revised to allow CLIA-certified 
laboratories to refer specimens to laboratories operated under the 
Veterans Administration (VA), the Department of Defense (DOD), and 
CLIA-exempt laboratories within a State whose licensure program has 
been granted approval under subpart E.
    Requirements pertaining to the total testing process (preanalytic, 
analytic, and postanalytic) are now in subpart K. Specifically, subpart 
K has been revised to eliminate the QC requirements formerly at Sec.  
493.1202 and provisions pertaining to the FDA review and approval of 
manufacturers' test system QC for CLIA purposes as specified at Sec.  
493.1203 in the February 28, 1992 final rule with comment period. Also, 
subpart K is now structured to correlate with the movement of a 
specimen through the laboratory from acquisition to examination or 
testing, and reporting of results. The requirements were not 
substantively changed to correspond to the testing process, but we did 
eliminate redundant requirements and revise others for clarification.
    In addition, subpart K now incorporates the requirements formerly 
in Subpart P--Quality Assurance; Moderate Complexity (Including the 
Subcategory) or High Complexity Testing, or Any Combination of These 
Tests. These requirements are now located under the appropriate 
sections in subpart K, that is, General Laboratory Systems, Preanalytic 
Systems, Analytic Systems, and Postanalytic Systems. We listed the 
quality assurance (renamed quality assessment (QA) to more clearly 
reflect the activities performed) activities for each phase of testing. 
For example, QA requirements for preanalytic activities, such as 
monitoring the medical necessity and completeness of test request 
information solicited and obtained by the laboratory, now appear at the 
end of the preanalytic section of subpart K under Sec.  493.1249. We 
believe that integrating the QA requirements into the various phases of 
the testing process enhances the understanding of the vital and 
important role QA plays in ensuring that quality services are provided 
by the laboratory throughout the entire testing process. To further 
emphasize and clarify the essential components of a comprehensive QA 
program, we are reiterating in each assessment section the laboratory's 
responsibility to: (1) Establish and follow written polices and 
procedures for an ongoing mechanism to monitor and assess each of its 
activities; (2) take corrective actions, as necessary, based on these 
assessments; (3) review the effectiveness of the assessments and 
corrective actions


[[Page 3642]]


taken; (4) revise policies and procedures, as necessary, to prevent 
recurrences of problems; (5) discuss the assessment activities and 
findings with the appropriate staff; and (6) document all assessment 
activities. To ensure the clarity of this final rule, many of the QA 
requirements from the former subpart P had to be rewritten.
    To conform with the names of the new subparts I, J, and K, the 
former Subpart M--Personnel for Moderate Complexity (Including the 
Subcategory) and High Complexity Testing has been renamed Personnel for 
Nonwaived Testing. In subpart M, we are finalizing the qualification 
requirements for directors of laboratories performing high complexity 
testing at Sec.  493.1443(b)(3). In addition, we are revising Sec.  
493.1443(b)(3)(i) by removing the reference to specific boards approved 
by HHS. All HHS-approved boards are listed on the Internet at http://cms.hhs.gov/clia/dirc/con.asp.
 HHS-approved boards will also be listed 
in Appendix C of the State Operations Manual (CMS Pub. 7), subpart M. 
This change will allow greater flexibility to update the list of HHS-
approved boards. Also, we are announcing two new HHS-approved boards; 
the National Registry for Clinical Chemistry at the doctoral level and 
the American Board of Forensic Toxicology.
    To clarify these changes, we have provided a distribution table, 
which contains a detailed list of sections that have been removed or 
redesignated.


III. Distribution Table


    The following crosswalk table enables the reader to easily locate 
where the requirements from the former rule have been relocated. It 
lists the former section titles along with the section titles as they 
appear in this final rule. In addition, the reorganized regulation now 
follows the path of patient specimens as they proceed through the 
clinical laboratory. This organizational structure was adopted at the 
recommendation of the Clinical Laboratory Improvement Advisory 
Committee to assist laboratories in better understanding the basic CLIA 
requirements.

IV. Analysis and Responses to Public Comments


    We received numerous comments on the final rule with comment period 
published on February 28, 1992 in the Federal Register. These comments 
were from State agencies, proficiency testing programs, professional 
organizations, the Clinical Laboratory Improvement Advisory Committee 
(CLIAC), laboratories, physicians, and the general public. Summaries of 
the public comments received and our responses to those comments are 
set forth below.


Subpart I--Proficiency Testing Programs for Tests of Moderate 
Complexity (Including the Subcategory), High Complexity, or Any 
Combination of These Tests


    We received a number of comments on the topic of proficiency 
testing. We intend to publish a notice of proposed rulemaking 
addressing proficiency testing issues in more detail in the future. We 
have, however, determined that it would be appropriate to include in 
this final rule a change that we believe is necessary to improve the 
operation of the CLIA proficiency testing program, related to the 
percentage of required agreement among participant or reference 
laboratories. Thus, we are addressing only one of the changes requested 
by the commenters and recommended by the CLIAC.
    Specific comments received and response to comments regarding 
subpart I are set forth below.
    Comment: A few commenters, professional organizations, and 
proficiency testing programs expressed their concerns over the change 
to a 90 percent consensus requirement to be reached before a 
proficiency testing sample could be graded. Commenters felt there 
should be a grade assigned to their samples. One commenter stated that 
their laboratory paid for samples, so grading should be required. 
Proficiency testing programs had similar opinions. The CLIAC 
recommended reducing the consensus required for grading proficiency 
testing challenges to decrease the number of ungradeable samples as 
ungraded proficiency testing is not effective in assisting laboratories 
in their quality assessment of test performance.
    Response: We agree with the commenters and are changing the 
percentage of required agreement among participant or referee 
laboratories to 80 percent in the specialties and subspecialties where 
90 percent agreement was previously required.


Subpart J--Patient Test Management for Moderate Complexity (Including 
the Subcategory), High Complexity, or Any Combination of These Tests


    Following publication of the final rule with comment period, we 
received approximately 150 comments regarding subpart J. The comments 
were in response to the requirements for specimen submission and 
handling; test requisition including oral requests and authorized 
persons; and test records and test reports, including confidentiality 
and referral of specimens. The majority of the commenters disagreed 
with some portion of the requirements and some commenters requested 
clarification of certain requirements while others offered specific 
revised language.
    Specific comments received and responses to comments regarding 
subpart J are set forth below.
    Comment: A number of State agencies disagreed with our removal of 
the requirement that laboratories comply with applicable Federal, 
State, and local laws.
    Response: We agree with the commenters and are reinstating the 
requirement now at Sec.  493.1101(c). As part of the partnering 
relationship with State agencies and local governments, the 
reinstatement of this requirement will allow us to support a State or 
local government that seeks to protect the public from actions it finds 
would be detrimental to public health.
    Comment: Some commenters disagreed with requiring written 
authorization for oral test requests, describing the difficulties that 
this requirement causes.
    Response: We acknowledge that when a laboratory asks that an oral 
request for patient testing be followed with a written request, there 
is no guarantee that one will be received. On January 19, 1993, we 
published a technical correction in the Federal Register (58 FR 5215) 
and (58 FR 5229) that amended the requirement formerly at Sec.  
493.1105. This requirement, now at Sec.  493.1241(b), states that oral 
requests for laboratory tests are permitted only if the laboratory 
requests written or electronic authorization for testing within 30 days 
of the oral request and documents the efforts made to obtain a written 
or electronic authorization.
    Comment: We received several comments recommending information the 
laboratory should solicit and obtain on the test requisition. 
Specifically, the commenters believe the age and sex of the patient, 
time of specimen collection, and the specimen source should be included 
since they are pertinent to either how the laboratory processes the 
specimen and/or how the test results are interpreted.
    Response: We agree with the commenters. The requirement, formerly 
at Sec.  493.1105(f), requires the laboratory to ensure that the 
requisition or test authorization includes any additional information 
relevant and necessary for accurate and timely testing and result 
reporting (for clarity, we are adding ``interpretation'' if applicable 
to this requirement). The requirement, now at Sec.  493.1241(c)(3), 
specifies that the laboratory must request the patient's sex and age or 
date of birth as normal values and interpretation of test results are 
often dependent on this information. Concurrently, we are redesignating 
age or date of birth requirements, formerly at Sec.  493.1105(e), for 
Pap smear requisitions to test requests (now at Sec.  493.1241(c)(3)). 
The time of specimen collection must also be requested when it is 
relevant for the testing to be performed. For example, this information 
is important when interpreting the results of peak and trough 
therapeutic drug assays. In addition, we are requiring that specimen 
source, when appropriate, be solicited on the test requisition. 
Specimen handling, preservation, and preparation (for example, use of 
proper transfer media, inoculation of media in microbiology and 
clinical cytogenetics, and the application of appropriate normal values 
reported with patient test results) are dependent on the origin of the 
specimen. Therefore, we are including specimen source, when 
appropriate, as part of the laboratory's submission, handling, and 
referral procedures (now at Sec.  493.1242(a)(3)). We are also 
requiring specimen source to be included on the test report if 
warranted (now at Sec.  493.1291(c)(5)). This routine laboratory 
practice was inadvertently omitted from the final rule with comment 
period.
    Comment: One organization representing members of the laboratory 
community objected to the amount of information that a laboratory must 
have on the test requisition, specifically the information that is 
needed when submitting a Pap smear. The organization stated that 
laboratories do not have access to patient records and are dependent on 
the authorized person ordering the test to provide this information. 
The organization agreed the information was important but assumed we 
would prohibit testing if all information was not obtained by the 
laboratory.
    Response: We agree with the commenter that the information being 
requested is important. Therefore, we are retaining the test request


[[Page 3652]]


requirements formerly at Sec.  493.1105, (now at Sec.  493.1241(c)) as 
relevant information necessary for proper test performance and 
interpretation. The test requisition requirements do not prohibit 
laboratories from performing the testing if the requested information 
is missing. Although we expect laboratories to obtain this information 
when possible, the potential negative impact of the missing information 
on the test results may be addressed or noted on the report.
    Comment: One State health department requested modification of the 
requirement for recording the time of specimen receipt into the 
laboratory, stating we should require the time of receipt only if it is 
pertinent to sample integrity, test method, or procedure.
    Response: We disagree with the commenter. Recording the date and 
time of specimen receipt enables the laboratory to determine the 
elapsed time between specimen receipt and reporting of patient test 
results. It also provides a mechanism to monitor transportation times 
for specimens referred to the laboratory. Therefore, we are retaining 
this requirement formerly at Sec.  493.1107(b) (now at Sec.  
493.1242(b)).
    Comment: One commenter stated the final rule with comment period 
did not require a person's name or unique identifier on the test 
report.
    Response: We agree with the commenter that the final rule with 
comment period did not specifically require a patient's name or unique 
identifier as part of the test report formerly at Sec.  493.1109. 
Therefore, we are adding at Sec.  493.1291(c)(1), a requirement for the 
laboratory report to include the patient's name with an identification 
number, or a unique patient identifier and identification number to 
ensure positive patient identification. The patient's name alone is not 
a unique identifier, and when used on the test report, the patient's 
name must be accompanied by an identification or accession number. When 
a patient's name is not used for confidentiality purposes, or when the 
identity of the person is not known, a unique patient identifier must 
be submitted with the specimen. The laboratory must also use an 
identification number. In reviewing the report requirements formerly at 
Sec.  493.1109(b), interpretation was omitted. Therefore, we are adding 
interpretation to the test report requirements at Sec.  493.1291(c)(6) 
for those test results that require supplemental information.
    Comment: Some commenters disagreed with requiring the name and 
address of the laboratory performing the test on the test report. They 
believed that too much information would make the report crowded and 
confusing. Another comment received from a professional organization 
acknowledged the benefit of this requirement, but stated its 
application to cumulative reports causes disruption of data 
presentation and utility of the report and, in some cases, the 
information cannot reasonably be included.
    Response: We agree the name and address of the laboratory 
performing the test is an essential piece of information that must be 
included on the test report. It provides a contact for the individual 
who requested or is using the test results when additional information 
is needed for result interpretation and patient care. If a laboratory 
determines its reports are crowded or confusing, it has complete 
latitude and responsibility to reorganize the report in a manner that 
will correct the problem as specified formerly at Sec.  493.1703 (now 
at Sec.  493.1299). A laboratory that generates cumulative reports may 
use a single character identifier (for example, an asterisk or 
subscript) to identify a particular reference laboratory that performed 
the test. This information (the name and address of the reference 
laboratory) may be defined on a subsequent page or on the back of the 
report. Laboratories may develop other formats to meet this 
requirement. However, we are retaining the requirement formerly at 
Sec.  493.1109(b) (now at Sec.  493.1291(c)(2)) to include the name and 
address of the laboratory where the test was performed.
    Comment: One commenter questioned the appropriateness of 
maintaining test records in the patient's chart or medical record.
    Response: The CLIA regulation does not preclude laboratories from 
storing test records in a patient's chart or medical record; however, 
records must include the following:
    [sbull] Test analysis (including instrument printouts, if 
applicable).
    [sbull] Identity of the personnel performing the test.
    To retain this type of information in a patient's chart or medical 
record may be cumbersome and impractical for QA activities; however, it 
is at the discretion of the laboratory.
    Comment: One commenter questioned whether computer records of 
reports are acceptable in lieu of paper files.
    Response: The requirement formerly at Sec.  493.1109(h) specifies 
that all test reports or an exact duplicate of each test report must be 
maintained by the laboratory in a manner that permits ready 
identification and timely accessibility. The information contained on 
the test report may be manually written, generated by an electronic 
system, maintained on microfilm, or any other means, provided it 
contains all of the information that was on the original test report. 
Therefore, we are deleting the reference to ``exact duplicate'' that 
was contained in the former Sec.  493.1109(h), and amending the 
language now at Sec.  493.1291(j) to clarify that the laboratory must 
be able to retrieve a copy of the original report. We are also making a 
conforming change in the retention requirement for test reports (now at 
Sec.  493.1105(a)(6)).
    Comment: Many commenters stated that the removal of the subpart on 
laboratory information systems (LIS) was inappropriate and not logical 
considering the current and future direction of collection and 
dissemination of laboratory data. Other commenters indicated that the 
current method of reporting patient results and the laboratory computer 
system was overlooked.
    Response: We agree with all of the commenters and are addressing 
some of the commenters' concerns pertaining to electronic patient and 
testing information by doing the following:
    [sbull] Adding a requirement at Sec.  493.1101(e) for laboratories 
to store and maintain records in a manner that ensures proper 
preservation. Proper storage of patient records that are collected in a 
LIS is essential for record preservation and accurate recall of patient 
information. Without proper storage and maintenance of records, the 
timeframes, identification, and the accessibility of records will not 
be possible.
    [sbull] Incorporating a requirement at Sec.  493.1241(e) for 
laboratories using LIS to ensure that the requisition information is 
accurately transcribed or entered. The laboratory may establish its own 
mechanism to meet this requirement, possibly through random checks or 
representative sampling of LIS patient testing information verified 
against that submitted on the original test request.
    [sbull] Adding a requirement at Sec.  493.1291(a) that requires 
laboratories to ensure patient test results are accurately and reliably 
sent from the point of data entry to the final report's destination in 
a timely manner. We are providing frequently encountered reporting 
scenarios that must be reviewed by the laboratory to ensure the 
accuracy and reliability of the transmitted patient result information.
    [sbull] Requiring at Sec.  493.1291(c) that the date of the test 
report be identified on the report. This date must be maintained as the 
date testing results


[[Page 3653]]


were generated as a final report and must not change on copies reported 
at a later date.
    The above requirements are intended to respond in part to the 
commenters' requests. We intend to publish, at a later date, a rule 
specific to laboratory information systems. For example, requirements 
for the establishment and verification of system programs, system 
security, system and device maintenance, system operator functions and 
responsibilities, and system backups.
    Comment: One commenter was concerned about limited record storage 
space on-site and asked if off-site storage of records would be 
acceptable provided the laboratory was able to produce these records 
during an inspection.
    Response: Records may be stored at a place of the laboratory's 
choosing providing the storage is appropriate and the laboratory can 
produce the documents within a reasonable time during the course of an 
inspection as required at Sec.  493.1773(c).
    Comment: Several commenters disagreed with the requirement to 
retain records for a minimum of 2 years or 5 years, depending upon the 
type of record. A professional organization questioned whether 
instrument printouts must be retained for 2 years if appropriate data 
are saved in a retrievable manner. Other commenters felt that 3 months, 
and, in one case, 6 months, would be sufficient time to retain 
instrument printouts.
    Response: We believe all records related to testing, for example, 
records of test requests, patient test records including, if 
applicable, instrument printouts, and copies of test reports are 
essential for the ongoing QA reviews performed by the laboratory. 
Instrument printouts are test records and are sometimes used as test 
reports and for these reasons must be retained for the appropriate 
length of time unless all information is duplicated in another record 
system. Additionally, CLIA requires biennial certification that 
includes an inspection of the laboratory's activities for compliance 
with CLIA requirements by either an on-site inspection of the 
laboratory or a self-assessment inspection through use of the Alternate 
Quality Assessment Survey (AQAS). These inspections require a review of 
the testing performed by the laboratory since the previous biennial 
inspection. Two years is the minimum amount of time records must be 
retained to ensure that they are available for review at inspection. 
However, we are clarifying the record retention requirements for 
immunohematology and blood and blood products formerly at Sec.  
493.1107 introductory text and Sec.  493.1221 (now at Sec.  
493.1105(a)(3)(ii)) and formerly at Sec.  493.1109 introductory text 
(now at Sec.  493.1105(a)(6)(i)) to ensure consistency with the FDA 
requirements for these types of records.


Subpart K--Quality Control for Tests of Moderate Complexity (Including 
the Subcategory), High Complexity, or Any Combination of These Tests


    In the final rule with comment period, the QC rules are located in 
subpart K and include the general QC requirements and specific QC 
requirements for each specialty and subspecialty of testing. A phase-in 
period provided less stringent general QC requirements for unmodified 
moderate complexity tests approved by the FDA through the premarket 
notification 510(k) or premarket approval (PMA) process.
    Following publication of the final rule with comment period, we 
received approximately 1,030 comments. Of these comments, 280 were 
directed at the general QC requirements, 67 pertained to the specialty 
and subspecialty QC requirements, and approximately 680 pertained to 
cytology and histopathology requirements. The majority of the comments 
disagreed with some portion of the requirements, indicating that the 
final rule with comment period was either too restrictive or too 
lenient. Some commenters requested clarification of certain 
requirements, while others offered specific revised language. A few 
comments agreed with the final rule with comment period, while others 
indicated the requirements had either been misinterpreted or misread. 
We addressed some of the commenters' issues in a technical correction 
published on January 19, 1993 in the Federal Register (58 FR 5215).
    In evaluating the comments and considering the types of revisions 
to make in this subpart, we obtained recommendations from the CLIAC and 
consulted with various professional organizations and laboratory 
personnel. In September 1996, we participated in public discussions at 
a 2-day meeting in Atlanta, Georgia. At the public meeting, 
manufacturers, laboratory organizations, and State representatives made 
presentations concerning QC principles, control materials and systems, 
manufacturers' recommendations, costs associated with control testing, 
and personnel implications. Their recommendation was to make changes to 
accommodate new technology. Our changes in this final rule are based on 
the advice and comments we received.
    Specific comments and response to comments regarding subpart K are 
set forth below.
    Comment: We received mixed comments concerning the general QC 
requirements. Some commenters felt the QC requirements were burdensome 
and would increase the cost of testing and asked that these 
requirements be deleted or revised. Conversely, some commenters agreed 
with the requirements, indicating that QC is absolutely essential to 
producing accurate test results and is good laboratory practice. Others 
stated the requirements of subpart K were both reasonable and 
attainable. A few commenters requested further clarification.
    Response: We agree with the comments that QC procedures are 
essential to good laboratory practice and production of accurate test 
results. Control procedures verify that the patient results are 
substantially unaffected by day-to-day variation caused by the test 
system, environment, or operator. While the requirement for 
implementing QC may initially increase the cost of testing in some 
settings, it may decrease the long term cost as improved accuracy and 
reliability of testing reduces the need for retesting and unnecessary 
procedures or treatments.
    Comment: A manufacturer's organization requested that Sec.  
493.1202(c) be revised to include those products not subject to the FDA 
clearance process to allow laboratories performing these tests to meet 
the phase-in QC requirements.
    Response: We agree that the regulation needs to be revised to 
include these products, and provisions addressing these products were 
added in the revisions to the regulations published in the January 19, 
1993 technical corrections (58 FR 5215). Since these products are not 
evaluated by the FDA, they could not be included under Sec.  
493.1202(c) but were added to Sec.  493.1202(b) and subject to all 
applicable standards of subpart K.
    Comment: Comments were divided concerning the phase-in of the 
general QC requirements. Some commenters agreed with the phase-in while 
others were opposed. Some commenters felt that following manufacturers' 
instructions should be sufficient to meet the CLIA QC requirements. 
Others expressed concern that FDA would not complete the review and 
approval of manufacturers' QC instructions by September 1, 1994. Most 
commenters opposed the phase-in provision. Some


[[Page 3654]]


commenters were concerned that manufacturers' QC protocols cleared by 
the FDA might be less stringent than the CLIA QC requirements. Other 
commenters disagreed with having two sets of general QC requirements, 
and other commenters were confused about the phase-in requirements and 
requested clarification.
    Response: We implemented a phase-in of the general QC requirements 
to allow previously unregulated laboratories performing only FDA-
approved or cleared, unmodified, and moderate complexity testing 
sufficient time to implement effective QC programs. During the phase-
in, the FDA was to establish a process to review and clear 
manufacturers' QC instructions for CLIA QC purposes. Under this 
process, laboratories could meet certain CLIA QC requirements by 
following the FDA-approved manufacturers' QC instructions. On four 
occasions, we extended the phase-in of the general QC requirements that 
are currently in effect until December 31, 2002. However, because the 
CLIA program is user fee funded, we decided it would be prudent to wait 
until the phase-in period ended before implementing the FDA QC review. 
This afforded us the survey experience necessary to determine whether 
an additional FDA review would be of benefit to laboratories. We 
realized through our experience inspecting laboratories that an 
additional FDA review would not be of such benefit. Therefore, in this 
final rule, we are eliminating the phase-in requirements and 
establishing minimum general quality system requirements applicable to 
all nonwaived testing, regardless of complexity. In addition, we are 
removing all references to the FDA QC clearance process that was not 
implemented. However, we agree with the commenters that it is essential 
for laboratories to perform testing according to the manufacturers' 
test system instructions as required formerly at Sec.  493.1202(c)(1) 
(now at Sec.  493.1252(a)).
    Comment: A few comments were received in response to the 
environmental and safety requirements at Sec.  493.1204. Some 
commenters indicated that the requirements were too lenient. Others 
were opposed to exempting moderate complexity testing from the 
requirements at Sec.  493.1204 during the phase-in, stating that all 
laboratories should be subject to these requirements.
    Response: We agree with the commenters and therefore are retaining 
the requirement formerly at Sec.  493.1204 (now at Sec.  493.1101, 
subpart J) and applying it to both moderate and high complexity 
testing. In addition, we are providing some flexibility to the 
requirement formerly at Sec.  493.1204(b) (now at Sec.  493.1101(d)) 
that requires laboratories to post safety precautions. The revisions 
now require that safety procedures be accessible rather than posted.
    Comment: We received several comments concerning the requirements 
at Sec.  493.1205. Most commenters opposed the requirement prohibiting 
the use of expired reagents. One commenter requested clarification of 
Sec.  493.1205(c)(1) that requires the laboratory to define criteria 
for reagent and specimen storage conditions.
    Response: We understand the concerns expressed regarding the use of 
rare and expensive reagents and materials beyond their expiration 
dates. However, the manufacturer has the responsibility for 
establishing expiration dates that ensure the reagents and materials 
will perform properly when used for patient testing. In addition, any 
changes in the labeling of in-vitro diagnostics must comply with Food, 
Drug, and Cosmetic Act requirements. Therefore, we are not making any 
revisions to the requirement formerly at Sec.  493.1205(e)(1) (now at 
Sec.  493.1252(d)) prohibiting the use of expired reagents and other 
materials.
    In regard to licensed biological and blood products, any exceptions 
to dating requirements must be granted by the FDA in the form of an 
amendment to the product license. In this final rule, we are 
consolidating all requirements pertaining to the immunohematological 
testing and distribution of blood and blood products (now at Sec.  
493.1271(b)).
    We are adding language to the requirement formerly at Sec.  
493.1205(c)(1) to clarify how the laboratory establishes and uses its 
criteria for storing reagents and patient specimens. The requirement 
now at Sec.  493.1252(b), states that the laboratory must define 
criteria for those conditions in the manufacturer's test system 
instructions, when available, that are essential for proper storage of 
reagents and specimens, and accurate and reliable test system operation 
and test result reporting. The criteria must be consistent with the 
manufacturers' instructions, if provided. These conditions must be 
monitored, documented, and include (1) water quality; (2) temperature; 
(3) humidity; and (4) electrical tolerances.
    Comment: One commenter agreed with the requirements at Sec.  
493.1211, Procedure manual. Another commenter suggested that the 
procedure manual requirements be deleted. Two commenters opposed 
permitting the use of the manufacturer's package insert to satisfy the 
requirements at Sec. Sec.  493.1211(b)(1) through 493.1211(b)(13). 
Another commenter suggested that laboratories be required to retain 
each procedure's original specifications and instructions for use as 
provided by the manufacturer, and maintain a list of any alterations or 
changes in the procedure manual.
    Response: We disagree with the commenter who requested that the 
procedure manual requirements be deleted. All laboratories must 
maintain and follow procedure manual instructions in order to provide 
uniform patient testing. Therefore, we are retaining the requirements 
for a procedure manual now at Sec.  493.1251. Laboratories may use the 
manufacturer's test system instructions to meet many of the procedure 
manual requirements, but must supplement them with any laboratory-
specific information related to its testing and reporting practices. 
Examples are the laboratory's procedures for reporting patient test 
results, including panic values or alert values, corrective actions to 
follow when test systems become inoperable, and criteria for specimen 
referral. The use of the manufacturer's test system instructions to 
meet many of the procedure manual requirements is permitted to ensure 
that laboratories follow the manufacturer's instructions for patient 
testing and to minimize the burden on laboratories in developing 
procedure manuals.
    For clarity and consistency, we are reiterating the requirements 
formerly at Sec. Sec.  493.1103(a) and 493.1211(b)(14) (now at 
Sec. Sec.  493.1242 and 493.1251) that the laboratory have written 
policies and procedures for specimen submission. In addition, we 
included language now at Sec.  493.1251(b)(13) to clarify the use of 
laboratory information systems for entering patient test results.
    In addition, we agree with the commenter that laboratories must 
have copies of test procedures. Therefore, we are retaining the 
requirement now at Sec.  493.1251(e) that laboratories must maintain a 
copy of the procedure with the dates of initial use and discontinuance 
for 2 years after a procedure is no longer used.
    Comment: Several commenters opposed the requirement at Sec.  
493.1211 for the director to approve, date, and sign the procedure 
manual, approve any change in procedure, or re-approve the manual 
should there be a change in directorship. One commenter suggested that 
the requirement be revised to state each procedure must be approved by 
the director before patient testing.
    Response: The director is the individual ultimately responsible for 
the operation and administration of the


[[Page 3655]]


testing facility and is therefore responsible for authorizing all 
testing procedures and any alterations or revisions of these 
procedures. If a change in directorship occurs, re-approval of the 
manuals by the new director is necessary since he or she assumes 
responsibility for all testing procedures and any alterations or 
revisions of the procedures. We agree with the comment stating that 
each procedure should be approved by the director before patient 
testing. Therefore, we are revising the requirement formerly at Sec.  
493.1211(d) (now at Sec.  493.1251(d)) to specify that the director 
reviews each procedure and change in procedure before use. We are also 
emphasizing that we do not expect laboratories to suspend testing for 
those procedures already in use that may not have been approved before 
patient testing. However, effective April 24, 2003, all alterations in 
current procedures and all newly implemented procedures must be 
reviewed and signed by the director before use.
    In addition, we are revising the requirement formerly at Sec.  
493.1211(e) (now at Sec.  493.1251(d)) to include the provision that 
requires procedures to be re-approved if the directorship changes. 
Section 493.1251(d) now states, ``procedures and changes in procedures 
must be approved, signed, and dated by the current laboratory director 
before use.'' If the directorship changes, the current director would 
not be expected to suspend testing to review the procedures in use or 
changes to procedures approved by the previous director. However, the 
current director must review all procedures in use by the laboratory in 
a timely manner.
    Comment: Approximately one third of the comments received disagreed 
with Sec.  493.1213, Establishment and verification of method 
performance specifications. Some individuals opposed verifying the 
manufacturer's performance specifications for those methods cleared by 
FDA as meeting certain CLIA requirements for QC. One commenter 
disagreed with the requirement to establish performance specifications 
for those methods developed in-house, modified by the laboratory, or 
not cleared by FDA as meeting certain CLIA QC requirements. Another 
individual suggested that the standard be retroactive and apply to all 
test methods. One commenter asked that this standard be revised to 
state, ``The provisions of this section are not retroactive for 
previously unregulated laboratories. Previously unregulated 
laboratories are not required * * *.''
    Response: We understand the commenters' concerns about the time and 
resources necessary to establish or verify performance specifications. 
However, these requirements ensure that the laboratory has either 
established test system performance specifications or verified that it 
can obtain the manufacturer's performance specifications in the 
laboratory's environment using the laboratory's testing personnel. In 
addition, establishment or verification of performance specifications 
are integral to the laboratory's establishment of appropriate and 
effective QC and calibration protocols. These protocols must include 
descriptions of the numbers, types, and concentrations of all 
calibration and control materials, as well as the performance 
intervals. Calibration and control protocols based on unverified 
performance specifications could result in poorly controlled and 
inaccurate testing. In the interest of establishing appropriate 
calibration and control practices and improving the reliability, 
accuracy, and usefulness of patient testing, we are retaining the 
requirements formerly at Sec.  493.1213, and are now applying them to 
nonwaived testing at Sec.  493.1253.
    Laboratories employing methods (not modified by the laboratory) 
that have manufacturer-established performance specifications must 
demonstrate before reporting patient test results that they can obtain 
performance specifications for accuracy, precision, and reportable 
range of test results for the test system, comparable to those 
established by the manufacturer. The laboratory director must decide 
the extent to which these performance specifications are verified based 
on the method, testing conditions, and personnel performing the test.
    In addition, we are clarifying when a laboratory must establish 
test system performance specifications (for example, laboratories using 
a test system in which the manufacturer does not provide performance 
specifications) now at Sec.  493.1253(b)(2). Laboratories must, before 
reporting patient test results, establish, as applicable, performance 
specifications for the following performance characteristics: (1) 
Accuracy; (2) precision; (3) analytical sensitivity; (4) analytical 
specificity, including interfering substances; (5) reportable range of 
test results for the test system; (6) reference intervals (normal 
ranges); and (7) any other performance characteristic required for test 
performance.
    Section 493.1253(b)(1) uses the term ``FDA-cleared or approved test 
system'' as defined (at Sec.  493.2, Definition) in the November 9, 
1997 revisions to the Food, Drug and Cosmetic Act (Pub. L. 105-115), to 
mean a test system cleared or approved by the FDA through either the 
premarket notification (510(k)) or premarket approval (PMA) process for 
in-vitro diagnostic use. This includes test systems exempt from FDA 
premarket clearance or approval.
    Regulations do not have retroactive effect. The CLIA requirement's 
effective date became applicable to newly regulated laboratories on 
September 1, 1992. Those laboratories that were subject to regulations 
prior to this September 1, 1992 effective date were already required to 
validate test procedures under former Federal regulations before the 
CLIA requirements were implemented. This rule does not have a 
retroactive effect. Laboratories performing unmodified moderate 
complexity tests cleared or approved by the FDA are not required to 
retroactively verify the manufacturer's performance specifications. The 
results of the laboratory's control procedures, proficiency testing 
(required under subpart H) and assessment activities are used to verify 
test performance. However, as of April 24, 2003, laboratories must, 
before testing, either verify or establish performance specifications 
for any new test system.
    Comment: Some commenters expressed approval of the requirements for 
the establishment and verification of a test system's method 
performance specifications before its use, and maintaining records of 
this activity while the test system is used for patient testing.
    Response: We accept these positive comments and are retaining the 
requirements for the establishment and verification of method 
performance specifications formerly at Sec.  493.1213 (now at Sec.  
493.1253). However, we realize the QC record retention requirements 
formerly at Sec.  493.1221 may have been misinterpreted as permitting 
the laboratory to discard method performance specification records 
after a 2-year period even though the method may have continued to be 
used beyond this timeframe. Therefore, the analytic systems record 
retention requirement formerly at Sec.  493.1221 (now at Sec.  
493.1105(a)(3)(i)) specifies that records of the laboratory's 
establishment and verification of method performance specifications 
must be retained for the period of time the test system is in use by 
the laboratory, but not less than 2 years. In addition, we are revising 
the original QC record retention requirement to accommodate the 
reorganization of the regulation and clarify its intent.
    Comment: A few commenters disagreed in general with the


[[Page 3656]]


requirements at Sec.  493.1215, Equipment maintenance and function 
checks. Other commenters requested clarification. One commenter felt 
that the requirements were too stringent, and another offered specific 
language for revision. One commenter felt CMS, not the manufacturer, 
should establish the frequency for performing function checks.
    Response: Equipment maintenance and function checks are necessary 
to ensure accurate and reliable test performance. We are relocating the 
requirement formerly at Sec.  493.1215 (now at Sec.  493.1254) and 
renaming it Maintenance and function checks. Laboratories using 
unmodified manufacturers' equipment, instruments, or test systems must 
perform maintenance and function checks as defined by the manufacturer 
with at least the frequency specified by the manufacturer. Laboratories 
must also document maintenance and function checks performed. We are 
adding language at Sec.  493.1254(a)(2) requiring that function checks 
be within the manufacturer's established limits before conducting 
patient testing. We are also retaining the present requirement (now at 
Sec.  493.1254(b)) for laboratories to establish protocols that ensure 
proper test system performance, accurate and reliable test results and 
test reporting for equipment, instruments, or test systems developed 
in-house, commercially available but modified by the laboratory, or 
when protocols for maintenance and function checks are not provided by 
the manufacturer. In addition, laboratories must document the 
maintenance and function checks performed.
    Under this final rule, we are not defining intervals for the 
performance of maintenance or function checks because the manufacturer 
is better able to define the appropriate procedures and intervals 
necessary to maintain and ensure proper equipment, instrument, and test 
system performance.
    Comment: Several commenters suggested that Sec.  493.1217, 
calibration and calibration verification, or substantially equivalent 
requirements, should also apply to FDA-approved or cleared, unmodified 
moderate complexity testing at Sec.  493.1202(c). In addition, we 
received comments requesting clarification of Sec.  493.1217. One 
commenter stated that CMS, not the manufacturer, should establish the 
frequency of calibration. A manufacturer commented that a loose 
interpretation of the calibration verification requirement to assay 
calibration materials in the same manner as patient samples is needed 
for certain blood gas analytes because buffers and gases used to 
calibrate the instruments are not like patient samples and cannot be 
assayed in the same manner as patient samples.
    Response: We agree with the commenters and are specifying in this 
final rule that effective, April 24, 2003, calibration and calibration 
verification requirements (now at Sec.  493.1255) will apply to all 
nonwaived testing.
    To respond to the commenters' concerns that the calibration and 
calibration verification requirements are unclear, we are making some 
minor revisions in language for clarification purposes and removing 
duplicate requirements. For example, the definitions of calibration and 
calibration verification and reportable range are being slightly 
modified (now at Sec.  493.2). We are also removing the requirement 
formerly at Sec.  493.1217(b)(2)(ii)(B)(1) for laboratories to perform 
calibration verification using calibration materials appropriate for 
the methodology and, if possible, traceable to a reference method or 
reference material of known value to allow laboratories flexibility in 
choosing materials for calibration verification.
    In addition, we are retaining the requirement for laboratories, at 
a minimum, to perform calibration and calibration verification 
procedures using the manufacturers' test system instructions and the 
criteria verified or established by the laboratory formerly at 
Sec. Sec.  493.1217(b)(1) and 493.1217(b)(2) (now at Sec. Sec.  
493.1255(a)(1), 493.1255(a)(2), 493.1255(b)(1) and 493.1255(b)(2)). We 
are also retaining the requirement that calibration must be performed 
whenever calibration verification procedures are unacceptable and 
calibration verification be performed using a minimum of 3 values to 
verify the laboratory's reportable range, at least once every 6 months 
or whenever an event occurs as specified formerly at Sec.  
493.1217(b)(2)(ii)(C) (now at Sec.  493.1255(b)(3)).
    In response to the comment that the frequency of calibration be 
mandated by CMS, we are retaining the requirement formerly at Sec.  
493.1217(b)(1) (now at Sec.  493.1255(a)) that requires laboratories to 
calibrate according to the manufacturer's instructions, if provided, 
and the laboratory's specifications. We believe that laboratories 
should perform calibration at the interval specified by the 
manufacturer to ensure proper instrument and test system performance. 
For calibration verification formerly at Sec.  493.1217(b)(2) (now at 
Sec.  493.1255(b)), laboratories are to follow the manufacturer's 
specifications and the laboratory's established protocols for 
calibration verification that must be performed at least once every 6 
months. We believe this is the maximum interval allowable for verifying 
accuracy and stability. In addition, we are emphasizing that these 
regulations set forth minimal requirements. In establishing or 
verifying performance specifications as required at Sec.  493.1253, the 
laboratory may find it necessary to calibrate or verify calibration 
more frequently or to use more calibration materials than required at 
Sec.  493.1255.
    In response to the comment concerning the inability of testing 
calibration materials (buffers and gases) in the same manner as patient 
specimens when verifying the calibration of blood gas assays, we are 
retaining the additional requirements for routine chemistry formerly at 
Sec.  493.1245 (now at Sec.  493.1267) that supersede the general 
calibration and calibration requirements at Sec.  493.1255. Section 
493.1267(a) specifically addresses calibration and calibration 
verification of blood gas analyses and states the laboratory must 
calibrate or verify calibration according to the manufacturer's 
specifications and with at least the frequency recommended by the 
manufacturer. As long as the laboratory follows the manufacturer's 
calibration and calibration verification instructions for the blood gas 
instrument, the CLIA requirements for calibration and calibration 
verification are met.
    Comment: We received many comments concerning various components of 
Sec.  493.1218, Control procedures. Some commenters misread the CLIA 
regulation, and others offered specific language for revision. Most 
commenters opposed testing two levels of control material each day of 
use. One commenter indicated that the CLIA requirements are burdensome 
and will increase the cost of testing. Some commenters expressed 
concern that the requirements are arbitrary and do not recognize unit 
use test systems. Another commenter asked if procedural controls may be 
used to satisfy the control requirements.
    Response: We appreciate the commenters' concerns about the 
frequency and costs of performing control testing. However, CLIA 
regulations will continue to describe the purpose of control 
procedures, that is, to assess the accuracy and precision of test 
performance. The control procedures must monitor the complete 
analytical process by detecting immediate errors (those that occur due 
to test system failure, adverse environmental conditions or operator 
performance problems) and monitor over time the accuracy and precision 
of test performance that can be influenced by


[[Page 3657]]


subtle changes in test system performance, environmental conditions, 
and variance in operator performance (for example, different operators 
and same operator variations in specimen handling and testing).
    In response to the comments concerning unit use test systems and 
the use of procedural controls, we are making allowances for the use of 
procedural controls in Appendix C of the State Operations Manual (CMS 
Pub. 7) when equivalent quality procedures can be demonstrated.
    In addition, we are providing a definition for test system (now at 
Sec.  493.2). A test system is the instructions and all of the 
instrumentation, equipment, reagents, and/or supplies needed to perform 
an assay or examination and generate test results.
    A control material must detect errors in the entire testing 
process. It must also monitor the quality of the results provided by 
the test system. It may be supplied by the test system manufacturer or 
another source. We are also relocating the requirement for control 
materials to be
