Summary
Effective immediately, HCPCS codes G0482 and G0483 (definitive drug testing with 15-21 and 22+ drug classes respectively) are no longer reimbursable under Clinical Policy CP.MP.50. Codes G0480 and G0481 remain covered when medical necessity is documented. Billing teams must stop submitting claims for G0482/G0483 and transition to G0480/G0481 with proper medical necessity documentation.
Action Required
Effective immediately (06/04/26): Billing team must (1) update billing system to deny or block submission of HCPCS codes G0482 and G0483 for all Ambetter plans; (2) create alerts in EMR/billing software flagging any instances of G0482/G0483 to route to covered alternatives G0480/G0481; (3) update all encounter forms and clinical templates to reflect that only G0480/G0481 are reimbursable; (4) notify all providers and clinical staff that definitive drug testing claims must be billed using G0480/G0481 codes only and must include medical necessity documentation; (5) conduct staff training on the policy change before submitting any further drug testing claims. Failure to comply will result in claim denials and revenue loss. Contact your Provider Relations Representative with questions.
