Centers for Medicare and Medicaid Services

The Medicaid Drug Rebate Program (MDRP) is an arrangement between Centers for Medicare & Medicaid Services (CMS), state Medicaid agencies, and participating drug manufacturers. The MDRP partially offsets the federal and state costs of most outpatient prescription drugs dispensed to Medicaid beneficiaries. Manufacturers must enroll with CMS and sign agreements to pay rebates on all drugs dispensed to people enrolled in Medicaid before HHSC considers the drug for inclusion on the Texas Medicaid formulary. HHSC requires a CMS-approved National Drug Rebate Agreement (NDRA) to commence the certificate of information process.

Refer to the Medicaid NDRA information at for instructions on participating in the MDRP.
