 National Drug Code (NDC)

Providers can refer to the Texas Vendor Drug Program (VDP) website at for the Texas NDC-to-HCPCS Crosswalk which identifies relationships between National Drug Codes (NDC) and Healthcare Common Procedure Coding System (HCPCS ) codes. The file is published at least quarterly.

Providers may  only be reimbursed for clinician-administered drugs and biologicals whose manufacturers participate in the Centers for Medicare & Medicaid Services (CMS) Drug Rebate Program and that show as active on the CMS list for the date of service the drug is administered

Physician-administered drugs that do not have an appropriate NDC to HCPCS combination for the procedure code that is submitted will not be reimbursed by the following programs:

  • Medicaid fee-for-service
  • Children with Special Health Care Needs (CSHCN) Services Program,
  • Texas Women’s Health Program (TWHP),
  • Medicaid Family Planning, the Expanded Primary Health Care (EPHC) Program, and
  • Managed Care Organization (MCO) encounters for clinician-administered drugs.

Claims submitted with these drugs must adhere to the TX NDC-to-HCPCS Crosswalk.
