Medicaid Drug Rebate Program

The Medicaid Drug Rebate Program requires drug manufacturers to sign a rebate contract with the Center for Medicare and Medicaid Services’ (CMS).  Manufacturers must pay rebates to the states based on the number of units of their product that were paid for by the state, and the states in turn, must cover the drug manufacturers' products.  The drug rebates apply to drugs supplied to Medicaid fee-for-service or managed care clients either through a contracted pharmacy or administered by a contracted physician/clinician.

Supplemental Medicaid Drug Rebate Program

The Supplemental Drug Rebate Program works in conjunction with the Medicaid Preferred Drug List (PDL).  In order for a manufacturer's product to be included on the PDL, a manufacturer must agree to pay an additional, supplemental rebate amount on their products.  Physicians that prescribe a manufacturer's product that is in a reviewed class, but were not selected as the preferred drug, are required to obtain a prior authorization for the non-preferred product.
