Drug Coverage

HHSC maintains the Texas Drug Code Index (TDCI), or formulary, for the following programs:

  • Medicaid
  • Children’s Health Insurance Program (CHIP)
  • Children with Special Health Care Needs (CSHCN) Services Program
  • Healthy Texas Women (HTW) Program
  • Kidney Health Care (KHC) Program

We require drug manufacturers to complete the TDCI Certification of Information (COI) to request the addition of drugs and products to the formulary. The COI is for Medicaid formulary only. Manufacturers do not request addition to the CHIP, CSHCN, HTW, or KHC programs.

MCOs must adhere to the Medicaid and CHIP formularies.

Drugs classified with Drug Efficacy Study Implementation (DESI) values "5" or "6" are not covered.
