Medicaid Drug Formulary

The Vendor Drug Program Formulary is available to assist providers help their patients obtain medications. Our formulary tools include information about which state programs cover each drug (e.g. Medicaid, CHIP) and whether a Medicaid non-preferred or clinical prior authorization is required. Formulary information is available:

Outpatient Drug Prior Authorization

The formulary used for people enrolled in Medicaid consists of preferred and non-preferred drugs. Non-preferred drugs require prior authorization. Some drugs on the Medicaid formulary (whether preferred or non-preferred) may also be subject to clinical criteria requiring prior authorization.

  • Traditional Medicaid: prescribing providers or their representatives should call the Texas Prior Authorization Call Center. Some medications requiring clinical prior authorization are reviewed internally by the Vendor Drug Program.
  • Medicaid managed care: prescribing providers or their representatives should contact the managed care plan. Prior Authorization call center phone numbers may vary by health plan. The Prescriber MCO Assistance Chart (PDF) identifies prior authorization and member call center phone numbers for each plan.

It is the prescribing provider’s responsibility to obtain the prior authorization. In the event prior authorization has not been obtained at the time the prescription is presented at the pharmacy, pharmacies will alert the prescribing provider to obtain prior authorization. Dispensing an emergency supply provides the client with an immediate dose of the medication but requires a return trip to the pharmacy for the full prescription or alternate therapy. A 72-hour emergency prescription claim is available for all people enrolled in Medicaid.

Criteria for Vitamin and Minerals Products for Medicaid

Vitamin and mineral products prescribed or ordered by a physician to treat various conditions are a benefit of Texas Medicaid through the Comprehensive Care Program (CCP) for clients who are 20 years of age and younger. Products require prior authorization and are submitted to TMHP with the corresponding procedure code and state-identified modifier. Prior authorization is a condition for reimbursement and not a guarantee of payment. Refer to the Texas Medicaid Provider Procedures Manual (Children's Services Handbook, "Medicaid Children’s Services Comprehensive Care Program") for more information on obtaining a prior authorization.
