CPT® Proprietary Laboratory Analyses (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

Application submissions are now being accepted for requests for codes to be added to the PLA section of the CPT code set for the spring application cycle ending April 12

Review the new codes in the MAAA Guidelines that include PLA.

CPT PLA Agenda

The proposed agenda for the May 2017 CPT PLA Panel meeting identifies the test names and requested descriptions for each test.

PLA Application and Publication Calendar

PLA test codes will be released and posted online on a quarterly basis (fall, winter, spring and summer) in data files. New codes are effective the quarter following their publication. These codes will also be included in the annual update of the CPT codebook beginning in 2018.

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.
