Test Panel Definition: A predetermined set of medical tests composed of individual laboratory tests, related by medical condition, specimen type, frequency ordered, methodology or types of components to aid in the diagnosis/treatment of disease.
Palmetto considers the performance of multiple molecular biomarkers, regardless of whether the test requisition lists the tests as a panel or individually, and completed on a single sample to be a 'panel' of tests. Therefore, each panel should be registered and billed with a single CPT code and a unique MolDX identifier. Based on data analysis of MolDX claims, labs are submitting multiple biomarker 'panels' as individual tests similar to the submission of the previous stacking codes.
Example: A lab receives a patient specimen and performs the following tests:
CPT code 81225-CYP2C19, cv
CPT code 81240-F2, 20210G>A
CPT code 81241-F5, Leiden
The panel of three tests listed above should be registered and claims submitted with CPT code 81479 and a single MolDX ID. If the lab also performs one of the three panel’s biomarkers on patient specimens, each biomarker must also be registered and receive a unique ID to submit on claims when only that biomarker is performed. Again, a single CPT code should be billed with a unique ID.
To correct this example, the lab must register four tests and receive identifiers for MolDX claim submission:
Clotting Test Panel
Labs should register all panels and obtain a unique MolDX identifier for each panel. If a lab does NOT perform single biomarker tests, they must notify the registry of this registration error.
