Medicare Part D Rebates Related to Drugs Dispensed by 340B Pharmacies

Drug manufacturer rebates reduce the cost of the Part D program to beneficiaries and the Government. Manufacturers frequently do not pay rebates for Part D prescriptions filled at 340B-covered entities and contract pharmacies, since they are already providing a discount on the purchase of the drug. The Medicare Part D program does not share in the purchase discounts. Savings could be realized if sponsors and manufacturers agreed that eligible prescriptions filled at 340B pharmacies would receive rebates. We will identify potential rebate amounts that could have been obtained if pharmaceutical manufacturers paid rebates for drugs dispensed through the Medicare Part D program at 340B-covered entities and contract pharmacies.
