Molecular Lab Billing and PLA Codes
Molecular lab billing is the coding and claims process for genetic, genomic and other molecular diagnostic tests, which often use molecular pathology CPT codes or Proprietary Laboratory Analyses (PLA) codes and face detailed Medicare coverage rules. Sound Lab Consultants (SLC) provides molecular lab billing and revenue cycle management nationwide.
What makes molecular billing different
PLA codes are CPT codes ending in U that describe specific proprietary lab tests; CMS lists PLA codes such as 0563U in its waived-test notices (CMS MM14569: CLFS & CLIA HCPCS codes and waived tests)
Payment for many molecular tests is set on the CLFS (CMS: Clinical Laboratory Fee Schedule)
Coverage is frequently governed by LCDs; check the CMS Medicare Coverage Database
Some advanced tests have specific PAMA reporting considerations (CMS: CLFS PAMA reporting resources)
Molecular billing checklist
Confirm the correct CPT or PLA code for each test
Check applicable NCD/LCD coverage and documentation
Confirm the test is within the lab's CLIA certificate
Apply date-of-service rules (CMS: CLFS date of service policy)
Track molecular-specific denials
