Missing CLIA Certificate Numbers

A CLIA certificate number is a 10-character alphanumeric code (e.g., 19DXXXXXXX) that identifies a laboratory and is used to track it throughout its history, ensuring compliance with the Clinical Laboratory Improvement Amendments (CLIA) regulations. If a clinical laboratory service is billed on a claim without the CLIA, the claim will reject.

Missing NDC

The National Drug Code (NDC) is a unique 10-digit, 3-segment number used to identify drugs, serving as the FDA's identifier for drugs and found on drug packaging. If a professional claim is billed with a CPT or HCPCS code that requires an NDC number, and the NDC is missing, the claim will reject.
