*Coverage Gap: In 2018, Part D enrollees will receive a 65% discount on the total cost of their brand-name drugs purchased while in the donut hole. The discount includes, 50% discount paid by the brand-name drug manufacturer and will apply to getting you out of the donut hole, however the additional 15% paid by your Medicare Part D plan will not count toward your out of pocket. Also, Medicare Part D beneficiaries will receive a 56% discount on generic drugs purchased while in the donut hole and the 44% spent by the beneficiary will county towards their total out of pocket.

By 2020 government subsidies, discounts from drug companies and plan coverage are projected to cover 75% of medications in the coverage gap thereby matching the benefit provided in the Initial Coverage Period.
