Toxicology Lab Billing
Toxicology lab billing is the coding and claims process for drug testing, separating presumptive (screening) tests from definitive (confirmatory) tests and meeting payer medical necessity rules for each. Sound Lab Consultants (SLC) provides toxicology lab billing and revenue cycle management for clinical labs nationwide.
Key toxicology billing concepts
Presumptive drug tests use CPT 80305-80307, which differ by testing method, and only one may be reported per date of service (CMS MLN SE18001: Coding for drug testing and specimen validity)
CMS lists many waived drug test cups as 80305QW (CMS MM14569: CLFS & CLIA HCPCS codes and waived tests)
Medicare uses HCPCS G0480-G0483 (tiered by number of drug classes) and G0659 for definitive drug testing (CMS MLN SE18001: Coding for drug testing and specimen validity)
Coverage and frequency are often set by LCDs and billing articles such as CMS MCD Billing and Coding Article A56915: Urine Drug Testing; only one definitive drug code may be billed per patient per day
Orders and documentation must support medical necessity for each test
