PAMA Implementation: PLA Codes for Advanced Dx Tests Are Off to a Flying Start
PAMA implementation is so sweeping that it requires a shift in not just payment paradigm but also CPT codes.

PAMA implementation is so sweeping that it requires a shift in not just payment paradigm but also CPT codes. This has served as the impetus for development of a new class of codes known as Proprietary Laboratory Analyses (PLA) codes. Here's a quick overview of what's going on with PLA codes.
What PLA Codes Are All About
To the extent that the new PAMA lab payment regime is supposed to be based on market pricing, CMS had to create a coding system that could be used to track and monitor newfangled advanced diagnostic laboratory tests (ADLTs) and FDA-approved clinical diagnostic laboratory tests (CDLTs) reimbursed under PAMA. The new coding system is proprietary-based with codes being issued for specific products at the request of test developers and manufacturers.
PLAs are a new class of CPT codes developed by the American Medical Association (AMA) to meet that demand. The AMA has issued nearly two dozen PLA codes so far, all of which end in "U", including six that went into effect this October. In addition to ADLTs and CDLTs, the AMA has issued codes for "a range of tests" including genomic sequencing procedures and multi-analyte algorithm assays. Interpace Diagnostics, Vermillion, Thermo Fisher, Exosome Diagnostics and the Mayo Clinic are among those that have secured PLAs for their products. Here is the entire PLA roster to date:

(*) More than one PLA with an identical descriptor
Takeaway: While they make it easier to monitor sales of advanced tests, it remains to be seen whether the issuance of PLAs will have any measurable impact on market performance or persuade payors to cover the products.
