Summary
Starting in March 2026, New Mexico Medicaid (Turquoise Care) will reject claims missing taxonomy codes and deny claims with incorrect taxonomy or ZIP codes. All claims must include the correct taxonomy code matching the provider's HCA registration and the ZIP code where services were provided.
Action Required
Before March 1, 2026: Billing team must update claim submission system to require taxonomy codes on all New Mexico Medicaid claims. Access the New Mexico Medicaid Portal to verify correct taxonomy codes for each provider type and ensure they match HCA registration. Update billing software to validate ZIP codes match the physical service location. Train staff that claims without taxonomy codes will be rejected and claims with incorrect taxonomy or ZIP codes will be denied.
