Beginning in March 2026, New Mexico Medicaid (Turquoise Care) will reject claims without 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
By March 1, 2026: Billing team must update all claim submission processes to include correct taxonomy codes that match provider HCA registration. Verify ZIP codes reflect the physical location where services were provided. Access the New Mexico Medicaid Portal to confirm appropriate taxonomy codes for each provider. Update billing software to require taxonomy codes on all claims. Claims without taxonomy codes will be rejected and claims with incorrect taxonomy/ZIP codes will be denied.
