Summary
Effective October 1, 2026, Ambetter Health will no longer reimburse CPT codes 80320-80377 (Definitive Drug Testing Procedures). Billing teams must transition to G-series bundled laboratory codes for all drug testing claims to avoid denials.
Action Required
By September 30, 2026: Billing team must identify all CPT codes 80320-80377 currently in use and map them to appropriate G-series bundled laboratory codes in the billing system. Update billing software to reject or automatically convert claims using CPT 80320-80377 to the corresponding G-series codes for Ambetter Health members. Notify laboratory partners and providers of the code transition. Test the billing system changes before the October 1 effective date. Failure to transition to G-series codes will result in claim denials from Ambetter Health.
