Billing and Coding: Hepatic (Liver) Function Panel

Covered only when LCD L33907's reasonable and necessary criteria are met; non‑covered hepatic function tests must not be billed as covered and should be reported with the appropriate modifier. Documentation must be maintained in the medical record (legible, patient ID, dates, provider signature), must support the ICD‑10 and CPT/HCPCS codes and clinical indication/medical necessity, and if a different provider performs the test they must keep hard‑copy results, interpretations, and the ordering physician’s order.
