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 updated Clinical Policy CP.MP.50. Codes G0480 and G0481 remain covered when medical necessity is documented. Billing teams must immediately stop billing G0482 and G0483 and transition to alternative codes where appropriate.
Action Required
Effective immediately (06/04/26): Billing team must (1) update billing system to deny/reject claims submitted with HCPCS codes G0482 and G0483; (2) update denial messaging to reference Clinical Policy CP.MP.50; (3) audit pending claims for G0482/G0483 and resubmit with appropriate alternative codes (G0480 or G0481 if medical necessity is documented); (4) communicate to all providers that G0482 and G0483 are no longer billable; (5) update internal billing workflows and encounter forms to remove G0482/G0483 as billable options. Claims submitted with G0482 or G0483 will be denied by the payer. Contact Provider Relations Representative for code mapping guidance if needed.
