Lab & Toxicology Medical Billing Services

U.S.-based, physician-owned billing for lab and toxicology practices — Medicaid, Medicare, and commercial payers, inside the EHR you already use.

Why lab and toxicology billing is different

Billing that knows your specialty's rules

Drug testing is among the most audited billing in healthcare: presumptive screens (80305–80307) once per encounter, definitive panels (G0480–G0483) tiered by drug-class count, and every test backed by an order and a medical-necessity diagnosis.

We bill toxicology for treatment programs and independent labs daily — screens, confirmations, specimen validity, and the payer-specific frequency limits that quietly cap how often each plan pays.
