Claim edit: Invalid CLIA number format
Stedi now rejects 837P professional claims that report a Clinical Laboratory Improvement Amendments (CLIA) number in an invalid format.
What is a CLIA number?
A Clinical Laboratory Improvement Amendments (CLIA) number identifies a lab authorized to test human specimens. CLIA is a federal laboratory regulatory program administered by the Centers for Medicare & Medicaid Services (CMS) and applies to the operation of the laboratory. Medicare and Medicaid claims that bill for lab services require this number. Most other payers have the same requirement.
You can specify CLIA numbers at the claim level or on individual service lines.
Claim-level CLIA number

How the edit works
Each CLIA number is 10 characters with a fixed NNDNNNNNNN format: a two-digit state code, the literal D, then a seven-digit facility and check identifier.
If one or more CLIA numbers in a professional claim don’t follow this format, the payer may reject the claim.
This edit catches the issue before the claim reaches the payer. It prevents payer rejections, which take longer to resolve and delay payment for the provider.
