Medicaid patients can and should have access to medications that are medically necessary. This section has approved drug lists and other regulations.
The Illinois Medicaid program covers prescription drugs, as well as some over-the-counter (OTC) products, made by manufacturers that have a signed rebate agreement with the federal Centers for Medicare and Medicaid Services (CMS). Some prescription drugs and OTC products require prior approval from HFS before reimbursement.
