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. Only codes G0480 and G0481 are covered when medical necessity is indicated. Billing teams must immediately stop billing G0482 and G0483 and transition to the approved alternative codes.
Action Required
Immediately: Billing team must update billing system to deny/reject claims for HCPCS codes G0482 and G0483. Remove these codes from all encounter forms, order entry systems, and billing templates. Configure system to route denied G0482/G0483 claims with guidance to rebill using G0480 or G0481 instead (when medical necessity is documented). Notify all clinical providers and lab personnel that G0482 and G0483 are no longer billable effective 06/04/26. Update fee schedules to remove G0482 and G0483 pricing. Any claims submitted with G0482 or G0483 after the effective date will be denied, resulting in lost revenue and potential patient billing issues.
