Physician Office Lab (POL) Billing
Physician office lab (POL) billing is how a practice bills for tests it performs in its own in-office laboratory, which requires a CLIA certificate, correct test codes, the QW modifier for certain waived tests and the practice's CLIA number on claims. Sound Lab Consultants (SLC) provides POL billing and CLIA support nationwide.
