CLIA transitioned to a paperless system.
We no longer mail CLIA certificates or paper fee coupons. Additionally, all CLIA certification and survey fees must be paid
online
(payments by paper check are no longer accepted).
Laboratories must
have a
valid email address
on file to receive electronic CLIA certificates*, fee coupons*, and other CMS communications.
This does not apply to CLIA exempt states or state licensure.
Tip
: Use a business email address, or one that many staffers can access and use.

About CLIA
The Centers for Medicare & Medicaid Services (CMS) regulates all laboratory testing (except research) performed on humans in the U.S. through the Clinical Laboratory Improvement Amendments (CLIA) program.
The objective of CLIA is to ensure quality laboratory testing. In 1988, Congress passed CLIA regulations to establish quality standards for all testing laboratories to ensure that all patient test results are:
Accurate
Reliable
Timely
CLIA regulations are based on the complexity of the test method. The more complicated the test, the more stringent the requirements.
More information about laboratory test categorization and complexity
CLIA covers approximately 320,000 laboratory entities. State Survey Agencies are authorized to set and enforce CLIA standards.
Although all laboratories must be properly certified to receive Medicare or Medicaid payments, CLIA has no direct Medicare or Medicaid program responsibilities.
