Summary
Effective immediately, HCPCS codes G0482 and G0483 (definitive drug testing with 15-21 and 22+ drug classes respectively) are no longer reimbursable under the insurer's Clinical Policy CP.MP.50. Codes G0480 and G0481 remain covered when medical necessity is documented. The billing team must immediately stop billing G0482 and G0483 and transition to alternative covered codes.
Action Required
Effective immediately (06/04/26): Billing team must stop submitting claims for HCPCS codes G0482 and G0483. Update billing system denial rules to reject these codes before submission. Audit pending and recently submitted claims (last 30 days) for G0482/G0483 and resubmit using covered alternatives G0480 or G0481 with documented medical necessity. Notify all providers and lab partners of the coverage change. Update encounter templates and order entry systems to remove G0482/G0483 options. Route all drug-of-abuse testing orders to covered codes only. Failure to comply will result in claim denials and revenue loss.
