CPT® PLA Codes

Back to top

Proprietary Laboratory Analyses (PLA) codes are a new addition to the CPT® code set approved by the AMA CPT® Editorial Panel. They are alpha-numeric CPT codes with a corresponding descriptor for labs or manufacturers that want to more specifically identify their test. Tests with PLA codes must be performed on human specimens and must be requested by the clinical laboratory or the manufacturer that offers the test.

Types of PLA Code Tests

The PLA code section includes (but is not limited to) Advanced Diagnostic Laboratory Tests (ADLTs) and Clinical Diagnostic Laboratory Tests (CDLTs) as defined under the Protecting Access to Medicare Act of 2014 (PAMA). These analyses may include a range of medical laboratory tests including, but not limited to, Multianalyte Assays with Algorithmic Analyses (MAAA) and Genomic Sequencing Procedures (GSP).  The descriptor nomenclature follows, where possible, existing code conventions (e.g. MAAA, GSP).

Apply for CPT PLA Codes

Applications for the fall code cycle are now being accepted through the end of the day on July, 12, 2017. To submit an application please log into the PLA Portal.

Final Rule

On June 23, 2016, the Centers for Medicare & Medicaid Services (CMS) released the Medicare Clinical Diagnostic Laboratory Tests Payment System Final Rule page. This Final Rule implements PAMA provisions pertaining to pricing and coding for clinical laboratory tests covered on the Medicare Clinical Lab Fee Schedule (CLFS), as well as reporting requirements for clinical laboratories performing these tests.
