New PLA Codes Billable Under the Medicare CLFS to Be Aware Of
Here’s a quick briefing of the new codes that come into effect on April 1 that your billing staff should know about.
Labs that provide tests to beneficiaries covered by Medicare Part B need to be aware of upcoming Clinical Laboratory Fee Schedule (CLFS) changes. The Centers for Medicare & Medicaid Services (CMS) announced the changes in its quarterly Medicare Learning Network transmittal (CR 13082) on Feb. 2 and they officially take effect on April 1, 2023.1 One of the key changes that your billing staff may have to know about to ensure full and proper reimbursement is the addition of new Proprietary Laboratory Analysis (PLA) codes that Medicare will pay for under the CLFS. Here’s a quick briefing on the coding changes.
The Importance of PLA Codes
Proprietary Laboratory Analysis (PLA) codes are alpha numeric codes consisting of four digits and ending with the uppercase letter “U” that the AMA incorporated into its CPT coding system to enable labs or manufacturers to specifically identify their test products. PLA codes are assigned only if the lab or manufacturer requests them. PLA tests include:
- Advanced diagnostic laboratory tests (ADLTs)
- Clinical diagnostic laboratory tests (CDLTs) that are not ADLTs
- Multianalyte assays with algorithmic analyses (MAAA)
- Genomic sequencing procedures
PLA coded tests may be performed either by “one, sole source” lab or multiple labs to whom that lab licenses the test. Every year, CMS expands the list of PLA tests paid by Medicare. Initially, Medicare Administrative Contractors (MACs) decide on the price for PLA tests performed by labs in their jurisdiction until they’re nationally priced by CMS.
The New PLA Codes
Medicare will pay for 22 additional PLA tests, starting April 1, 2023:
