THE CLINICAL LABORATORY IMPROVEMENT AMENDMENTS (CLIA) APPLICATION
(FORM CMS-116)
INSTRUCTIONS FOR COMPLETION
CLIA requires every facility that tests human specimens
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, a
human being to meet certain Federal requirements.
If your facility performs tests for these purposes, it is
considered, under the law, to be a laboratory. Facilities
only collecting or preparing specimens (or both) or
only serving as a mailing service are not considered
laboratories. CLIA does not apply to a facility that only
performs forensic testing. CLIA applies even if only one
or a few basic tests are performed, and even if you are
not charging for testing. In addition, the CLIA legislation
requires financing of all regulatory costs through fees
assessed to affected facilities.
The CLIA application (Form CMS-116) collects
information about your laboratory’s operation which
is necessary to determine the fees to be assessed, to
establish baseline data and to fulfill the statutory
requirements for CLIA. This information will also provide
an overview of your facility’s laboratory operation. All
information submitted should be based on your facility’s
laboratory operation as of the date of form completion.
NOTE: WAIVED TESTS ARE NOT EXEMPT FROM
CLIA. FACILITIES PERFORMING ONLY THOSE TESTS
CATEGORIZED AS WAIVED MUST APPLY FOR A CLIA
CERTIFICATE OF WAIVER.
NOTE: Laboratory directors performing non-waived
testing (including PPM) must meet specific education,
training and experience under subpart M (42 CFR
PART 493) of the CLIA requirements. Proof of these
requirements for the laboratory director must be
submitted with the application. Information to be
submitted with the application include:
•

Verification of State Licensure, as applicable

•

Documentation of qualifications:
• Education (documentation necessary to ensure
CLIA personnel qualifications are met, e.g.,
diploma, transcript),
• Credentials, and
• Laboratory experience.

Individuals who attended foreign schools must have an
evaluation of their credentials determining equivalency
of their education to education obtained in the United
States. Failure to submit this information will delay the
processing of your application.

address (from the Facility Address), please complete the
appropriate sections on the form.
Mailing Address: This address is optional and may be
used if the laboratory wants to direct the mailing of the
CLIA fee coupon and/or CLIA certificate to an alternate
location, such as an accounts payable office. A Post
Office box number or Mail Stop number may be used as
part of the Mailing Address for this section.
Corporate Address: This address is optional and may
be used if the laboratory wants to direct the mailing of
the CLIA fee coupon and/or CLIA certificate to another
location, such as the main headquarters or home office
for the laboratory. A Post Office box number or Mail
Stop number may be used as part of the Corporate
Address for this section.
Form Mailing: Select the address (Physical, Mailing,
Corporate) where the CLIA fee coupon and CLIA
certificate are to be mailed.

ALL APPLICABLE SECTIONS MUST BE COMPLETED.
INCOMPLETE APPLICATIONS CANNOT BE PROCESSED
AND WILL BE RETURNED TO THE FACILITY. PRINT
LEGIBLY OR TYPE INFORMATION.

For Office Use Only: The date received is the date the
form is received by the state agency or CMS regional
office for processing.

GUIDELINES FOR COUNTING TESTS FOR CLIA
•

For chemistry, each non-calculated analyte is counted separately (e.g., Lipid Panel consisting of a total
cholesterol, HDL cholesterol, LDL cholesterol and triglycerides equals 4 tests).

•

For clinical cytogenetics, the number of tests is determined by the number of specimen types processed on each
patient; e.g., a bone marrow and a venous blood specimen received on one patient is counted as
two tests. NOTE: For all other genetic tests, the number of tests is determined by the number of results
reported in the final report.

•

For manual gynecologic and nongynecologic cytology, each slide (not case) is counted as one test.

•

For flow cytometry, each measured individual analyte (e.g. T cells, B cells, CD4, etc.) that is ordered and
reported should be counted separately.

•

For general immunology, testing for allergens should be counted as one test per individual allergen.

•

Genetics testing platforms are used in many of the testing specialties/subspecialties. The laboratory should
select the specialty or subspecialty according to the analyte the test is identifying.

•

For hematology, each measured individual analyte of a complete blood count or flow cytometry test that is
ordered and reported is counted separately. The WBC differential is counted as one test.

•

For histocompatibility, each HLA typing (including disease associated antigens) is counted as one test, each HLA
antibody screen is counted as one test and each HLA crossmatch is counted as one test. For example, a B-cell, a
T-cell, and an auto-crossmatch between the same donor and recipient pair would be counted as 3 tests.

•

For histopathology, each block (not slide) is counted as one test. Autopsy services are not included. For
those laboratories that perform special stains on histology slides, the test volume is determined by adding
the number of special stains performed on slides to the total number of specimen blocks prepared by
the laboratory.

•

For immunohematology, each ABO, Rh, antibody screen, crossmatch or antibody identification is counted as
one test.

•

For microbiology, susceptibility testing is counted as one test per group of antibiotics used to determine
sensitivity for one organism. Cultures are counted as one per test request from each specimen regardless
of the extent of identification, number of organisms isolated, and number of tests/procedures required for
identification. Each gram stain or acid-fast bacteria (AFB) smear requested from the primary source is counted
as one. For example, if a sputum specimen has a routine bacteriology culture and gram stain, a mycology test,
and an AFB smear and culture ordered, this would be counted as five tests. For parasitology, the direct smear
and the concentration and prepared slide are counted as one test.

•

For urinalysis, microscopic and macroscopic examinations, each count as one test. Macroscopics (dipsticks) are
counted as one test regardless of the number of reagent pads on the strip.

•

For all specialties/subspecialties, do not count calculations (e.g., A/G ratio, MCH, T7, etc.), quality control,
quality assurance, or proficiency testing assays.

If you need additional information concerning counting tests for CLIA, please contact your State agency.
