Coverage Gap Discount Program

The Medicare Coverage Gap Discount Program makes manufacturer discounts available to eligible Medicare beneficiaries receiving applicable drugs while in the coverage gap benefit phase. In order to participate in the Coverage Gap Discount Program, manufacturers must sign an agreement with CMS to provide the discount on all of its applicable drugs (i.e., prescription drugs approved or licensed under a New Drug Application or Biologic License Application). Beginning in 2011, only those applicable drugs that are covered under a signed manufacturer agreement with CMS can be covered under Part D.

CMS has provided on the download section of this page information about the Coverage Gap Discount Program contracting process, the list of participating manufacturers, and FDA Labeler Codes with the associated manufacturer names.
