association.
    This definition includes any foreign institution of higher education 
that HHS or its designee determines meets substantially equivalent 
requirements.
    Accredited laboratory means a laboratory that has voluntarily 
applied for and been accredited by a private, nonprofit accreditation 
organization approved by CMS in accordance with this part;
    Adverse action means the imposition of a principal or alternative 
sanction by CMS.
    ALJ stands for Administrative Law Judge.

[[Page 972]]

    Alternative sanctions means sanctions that may be imposed in lieu of 
or in addition to principal sanctions. The term is synonymous with 
``intermediate sanctions'' as used in section 1846 of the Act.
    Analyte means a substance or constituent for which the laboratory 
conducts testing.
    Approved accreditation organization for laboratories means a 
private, nonprofit accreditation organization that has formally applied 
for and received CMS's approval based on the organization's compliance 
with this part.
    Approved State laboratory program means a licensure or other 
regulatory program for laboratories in a State, the requirements of 
which are imposed under State law, and the State laboratory program has 
received CMS approval based on the State's compliance with this part.
    Authorized person means an individual authorized under State law to 
order tests or receive test results, or both.
    Calibration means a process of testing and adjusting an instrument 
or test system to establish a correlation between the measurement 
response and the concentration or amount of the substance that is being 
measured by the test procedure.
    Calibration verification means the assaying of materials of known 
concentration in the same manner as patient samples to substantiate the 
instrument or test system's calibration throughout the reportable range 
for patient test results.
    Challenge means, for quantitative tests, an assessment of the amount 
of substance or analyte present or measured in a sample. For qualitative 
tests, a challenge means the determination of the presence or the 
absence of an analyte, organism, or substance in a sample.
    CLIA means the Clinical Laboratory Improvement Amendments of 1988.
    CLIA certificate means any of the following types of certificates 
issued by CMS or its agent:
    (1) Certificate of compliance means a certificate issued to a 
laboratory after an inspection that finds the laboratory to be in 
compliance with all applicable condition level requirements, or reissued 
before the expiration date, pending an appeal, in accordance with Sec. 
493.49, when an inspection has found the laboratory to be out of 
compliance with one or more condition level requirements.
    (2) Certificate for provider-performed microscopy (PPM) procedures 
means a certificate issued or reissued before the expiration date, 
pending an appeal, in accordance with Sec. 493.47, to a laboratory in 
which a physician, midlevel practitioner or dentist performs no tests 
other than PPM procedures and, if desired, waived tests listed in Sec. 
493.15(c).
    (3) Certificate of accreditation means a certificate issued on the 
basis of the laboratory's accreditation by an accreditation organization 
approved by CMS (indicating that the laboratory is deemed to meet 
applicable CLIA requirements) or reissued before the expiration date, 
pending an appeal, in accordance with Sec. 493.61, when a validation or 
complaint survey has found the laboratory to be noncompliant with one or 
more CLIA conditions.
    (4) Certificate of registration or registration certificate means a 
certificate issued or reissued before the expiration date, pending an 
appeal, in accordance with Sec. 493.45, that enables the entity to 
conduct moderate or high complexity laboratory testing or both until the

agent; or in accordance with Sec. 493.57 to an entity that is 
accredited by an approved accreditation organization.
    (5) Certificate of waiver means a certificate issued or reissued 
before the expiration date, pending an appeal, in accordance with Sec. 
493.37, to a laboratory to perform only the waived tests listed at Sec. 
493.15(c).
    CLIA-exempt laboratory means a laboratory that has been licensed or 
approved by a State where CMS has determined that the State has enacted 
laws relating to laboratory requirements that are equal to or more 
stringent than CLIA requirements and the State licensure program has 
been approved by CMS in accordance with subpart E of this part.
    Condition level deficiency means noncompliance with one or more 
condition level requirements.

[[Page 973]]

    Condition level requirements means any of the requirements 
identified as ``conditions'' in subparts G through Q of this part.
    Credible allegation of compliance means a statement or documentation 
that--
    (1) Is made by a representative of a laboratory that has a history 
of having maintained a commitment to compliance and of taking corrective 
action when required;
    (2) Is realistic in terms of its being possible to accomplish the 
required corrective action between the date of the exit conference and 
the date of the allegation; and
    (3) Indicates that the problem has been resolved.
    Dentist means a doctor of dental medicine or doctor of dental 
surgery licensed by the State to practice dentistry within the State in 
which the laboratory is located.
    Equivalency means that an accreditation organization's or a State 
laboratory program's requirements, taken as a whole, are equal to or 
more stringent than the CLIA requirements established by CMS, taken as 
whole. It is acceptable for an accreditation organization's or State 
laboratory program's requirements to be organized differently or 
otherwise vary from the CLIA requirements, as long as (1) all of the 
requirements taken as a whole would provide at least the same protection 
as the CLIA requirements taken as a whole; and (2) a finding of 
noncompliance with respect to CLIA requirements taken as a whole would 
be matched by a finding of noncompliance with the accreditation or State 
requirements taken as a whole.
    CMS agent means an entity with which CMS arranges to inspect 
laboratories and assess laboratory activities against CLIA requirements 
and may be a State survey agency, a private, nonprofit organization 
other than an approved accreditation organization, a component of HHS, 
or any other governmental component CMS approves for this purpose. In 
those instances where all of the laboratories in a State are exempt from 
CLIA requirements, based on the approval of a State's exemption request, 
the State survey agency is not the CMS agent.
    FDA-cleared or approved test system means a test system cleared or 
approved by the FDA through the premarket notification (510(k)) or 
premarket approval (PMA) process for in-vitro diagnostic use. Unless 
otherwise stated, this includes test systems exempt from FDA premarket 
clearance or approval.
    HHS means the Department of Health and Human Services, or its 
designee.
    Immediate jeopardy means a situation in which immediate corrective 
action is necessary because the laboratory's noncompliance with one or 
more condition level requirements has already caused, is causing, or is 
likely to cause, at any time, serious injury or harm, or death, to 
individuals served by the laboratory or to the health or safety of the 
general public. This term is synonymous with imminent and serious risk 
to human health and significant hazard to the public health.
    Intentional violation means knowing and willful noncompliance with 
any CLIA condition.
    Kit means all components of a test that are packaged together.
    Laboratory means a facility for the biological, microbiological, 
serological, chemical, immunohematological, hematological, biophysical, 
cytological, pathological, or other examination of materials derived 
from the human body for the purpose of providing information for the 
diagnosis, prevention, or treatment of any disease or impairment of, or 
the assessment of the health of, human beings. These examinations also 
include procedures to determine, measure, or otherwise describe the 
presence or absence of various substances or organisms in the body. 
Facilities only collecting or preparing specimens (or both) or only 
serving as a mailing service and not performing testing are not 
considered laboratories.
    Midlevel practitioner means a nurse midwife, nurse practitioner, or 
physician assistant, licensed by the State within which the individual 
practices, if such licensing is required in the State in which the 
laboratory is located.
    Nonwaived test means any test system, assay, or examination that has 
not been found to meet the statutory

[[Page 974]]

criteria specified at section 353(d)(3) of the Public Health Service 
Act.
    Operator means the individual or group of individuals who oversee 
all facets of the operation of a laboratory and who bear primary 
responsibility for the safety and reliability of the results of all 
specimen testing performed in that laboratory. The term includes--
    (1) A director of the laboratory if he or she meets the stated 
criteria; and
    (2) The members of the board of directors and the officers of a 
laboratory that is a small corporation under subchapter S of the 
Internal Revenue Code.
    Owner means any person who owns any interest in a laboratory except 
for an interest in a laboratory whose stock and/or securities are 
publicly traded. (That is e.g., the purchase of shares of stock or 
securities on the New York Stock Exchange in a corporation owning a 
laboratory would not make a person an owner for the purpose of this 
regulation.)
    Party means a laboratory affected by any of the enforcement 
procedures set forth in this subpart, by CMS or the OIG, as appropriate.
    Performance characteristic means a property of a test that is used 
to describe its quality, e.g., accuracy, precision, analytical 
sensitivity, analytical specificity, reportable range, reference range, 
etc.
    Performance specification means a value or range of values for a 
performance characteristic, established or verified by the laboratory, 
that is used to describe the quality of patient test results.
    Physician means an individual with a doctor of medicine, doctor of 
osteopathy, or doctor of podiatric medicine degree who is licensed by 
the State to practice medicine, osteopathy, or podiatry within the State 
in which the laboratory is located.
    Principal sanction means the suspension, limitation, or revocation 
of any type of CLIA certificate or the cancellation of the laboratory's 
approval to receive Medicare payment for its services.
    Prospective laboratory means a laboratory that is operating under a 
registration certificate or is seeking any of the three other types of 
CLIA certificates.
    Rate of disparity means the percentage of sample validation 
inspections for a specific accreditation organization or State where 
CMS, the State survey agency or other CMS agent finds noncompliance with 
one or more condition level requirements but no comparable deficiencies 
were cited by the accreditation organization or the State, and it is 
reasonable to conclude that the deficiencies were present at the time of 
the most recent accreditation organization or State licensure 
inspection.

    Example: Assume the State survey agency, CMS or other CMS agent 
performs 200 sample validation inspections for laboratories accredited 
by a single accreditation organization or licensed in an exempt State 
during a validation review period and finds that 60 of the 200 
laboratories had one or more condition level requirements out of 
compliance. CMS reviews the validation and accreditation organization's 
or State's inspections of the validated laboratories and determines that 
the State or accreditation organization found comparable deficiencies in 
22 of the 60 laboratories and it is reasonable to conclude that 
deficiencies were present in the remaining 38 laboratories at the time 
of the accreditation organization's or State's inspection. Thirty-eight 
divided by 200 equals a 19 percent rate of disparity.

    Referee laboratory means a laboratory currently in compliance with 
applicable CLIA requirements, that has had a record of satisfactory 
proficiency testing performance for all testing events for at least one 
year for a specific test, analyte, subspecialty, or specialty and has 
been designated by an HHS approved proficiency testing program as a 
referee laboratory for analyzing proficiency testing specimens for the 
purpose of determining the correct response for the specimens in a 
testing event for that specific test, analyte, subspecialty, or 
specialty.
    Reference range means the range of test values expected for a 
designated population of individuals, e.g., 95 percent of individuals 
that are presumed to be healthy (or normal).
    Reportable range means the span of test result values over which the 
laboratory can establish or verify the accuracy of the instrument or 
test system measurement response.
    Sample in proficiency testing means the material contained in a 
vial, on a

[[Page 975]]

slide, or other unit that contains material to be tested by proficiency 
testing program participants. When possible, samples are of human 
origin.
    State includes, for purposes of this part, each of the 50 States, 
the District of Columbia, the Commonwealth of Puerto Rico, the Virgin 
Islands and a political subdivision of a State where the State, acting 
pursuant to State law, has expressly delegated powers to the political 
subdivision sufficient to authorize the political subdivision to act for 
the State in enforcing requirements equal to or more stringent than CLIA 
requirements.
    State licensure means the issuance of a license to, or the approval 
of, a laboratory by a State laboratory program as meeting standards for 
licensing or approval established under State law.
    State licensure program means a State laboratory licensure or 
approval program.
    State survey agency means the State health agency or other 
appropriate State or local agency that has an agreement under section 
1864 of the Social Security Act and is used by CMS to perform surveys 
and inspections.
    Substantial allegation of noncompliance means a complaint from any 
of a variety of sources (including complaints submitted in person, by 
telephone, through written correspondence, or in newspaper or magazine 
articles) that, if substantiated, would have an impact on the health and 
safety of the general public or of individuals served by a laboratory 
and raises doubts as to a laboratory's compliance with any condition 
level requirement.
    Target value for quantitative tests means either the mean of all 
participant responses after removal of outliers (those responses greater 
than 3 standard deviations from the original mean) or the mean 
established by definitive or reference methods acceptable for use in the 
National Reference System for the Clinical Laboratory (NRSCL) by the 
National Committee for the Clinical Laboratory Standards (NCCLS). In 
instances where definitive or reference methods are not available or a 
specific method's results demonstrate bias that is not observed with 
actual patient specimens, as determined by a defensible scientific 
protocol, a comparative method or a method group (``peer'' group) may be 
used. If the method group is less than 10 participants, ``target value'' 
means the overall mean after outlier removal (as defined above) unless 
acceptable scientific reasons are available to indicate that such an 
evaluation is not appropriate.
    Test system means the instructions and all of the instrumentation, 
equipment, reagents, and supplies needed to perform an assay or 
examination and generate test results.
    Unsatisfactory proficiency testing performance means failure to 
attain the minimum satisfactory score for an analyte, test, 
subspecialty, or specialty for a testing event.
    Unsuccessful participation in proficiency testing means any of the 
following:
    (1) Unsatisfactory performance for the same analyte in two 
consecutive or two out of three testing events.
    (2) Repeated unsatisfactory overall testing event scores for two 
consecutive or two out of three testing events for the same specialty or 
subspecialty.
    (3) An unsatisfactory testing event score for those subspecialties 
not graded by analyte (that is, bacteriology, mycobacteriology, 
virology, parasitology, mycology, blood compatibility, immunohematology, 
or syphilis serology) for the same subspecialty for two consecutive or 
two out of three testing events.
    (4) Failure of a laboratory performing gynecologic cytology to meet 
the standard at Sec. 493.855.
    Unsuccessful proficiency testing performance means a failure to 
attain the minimum satisfactory score for an analyte, test, 
subspecialty, or specialty for two consecutive or two of three 
consecutive testing events.
    Validation review period means the one year time period during which 
CMS conducts validation inspections and evaluates the results of the 
most recent surveys performed by an accreditation organization or State 
laboratory program.
    Waived test means a test system, assay, or examination that HHS has 
determined meets the CLIA statutory criteria as specified for waiver 
under
