Medicare Part D Savings Under the Manufacturer Discount Program vs Coverage Gap Discounts

When comparing the Coverage Gap Discount (CGD) and the Manufacturer Discount Program (MDP) in Medicare Part D, Medicare would have received $34 billion from drug makers under the MDP, compared to $17 billion under the CGD based on 2022 data. Discounts in the MDP also increased substantially for high-cost specialty drugs, highlighting how this policy change will affect Medicare Part D spending going forward.
