The discount for brand-name drugs purchased in the Coverage Gap will be ultimately paid by the manufacturer.
Medicare (that is, the Center for Medicare and Medicaid Services) will provide monthly payments to the Part D plans for the manufacturer discounts made available to their enrollees under the Discount Program.
These payments will be calculated based on projections of non-LIS enrollees and medication use,. After the end of the contract year, CMS will reconcile the payments made against the purchases and final payments will be distributed to the plans.
Please note that the 7% discount on generic drugs is being paid by the plans.
The Explanation of Benefits (EOB) persiodically sent to you from your Medicare Part D plan provider will clearly show your drug discount in the Coverage Gap and who is paying for the discounts.
