Summary

Effective October 1, 2026, Ambetter Health will no longer reimburse CPT codes 80320-80377 (Definitive Drug Testing Procedures). Providers must transition to billing G-series bundled laboratory codes instead. This represents a complete coverage elimination for these specific drug testing procedure codes.

Action Required

Before Oct 1, 2026
By September 30, 2026: Billing team must complete the following: (1) Audit current billing patterns to identify all claims using CPT codes 80320-80377 for Ambetter Health patients; (2) Update billing software to block submission of CPT codes 80320-80377 to Ambetter Health effective October 1, 2026; (3) Identify the appropriate G-series bundled laboratory codes that replace each discontinued code and update billing templates and encounter forms; (4) Notify all laboratory and clinical staff that drug testing procedures must be billed using G-series codes for Ambetter plans; (5) Establish internal communication protocol to redirect any staff attempting to bill the old codes. Failure to transition will result in claim denials and revenue loss for all drug testing procedures billed to Ambetter Health after October 1, 2026. Contact Ambetter Provider Relations Representative for specific G-code mappings if unclear.
