Update for CPT Codes 80320-80377: Effective 10/1/2026

By September 30, 2026: Billing team must immediately identify all current uses of CPT codes 80320-80377 in the billing system and replace them with the appropriate G-series bundled laboratory codes. Update billing software to deny or reject claims using CPT 80320-80377 effective October 1, 2026. Audit all pending and scheduled drug testing orders to ensure correct code assignment before the effective date. Notify all providers and clinical staff of the code transition through staff meetings and written communication. Contact Ambetter Health Provider Relations Representative to confirm the exact G-series code mappings for your specific drug testing panels. Failure to transition to G-series codes will result in claim denials and loss of reimbursement for all definitive drug testing procedures.
