Medicare Part D 


Information for Medicare Part D enrollees:

How will I know if I’ve reached the coverage gap?

The Explanation of Benefits notice, which your drug plan mails to you each month when you fill a prescription, will tell you how much you’ve spent on covered drugs and whether you’ve entered the coverage gap.

Will I need to do anything to get the rebate check?

No. There are no forms to fill out. Medicare will automatically send a check that’s made out to you. You do not need to provide any personal information like your Medicare, Social Security, or bank account numbers to get the rebate check. Do not give your personal information to anyone who calls you about the $250 rebate check. Call 1-800-MEDICARE (1-800-633-4227) to report anyone who asks for your personal information. TTY users should call 1-877-486-2048.

What if I don’t get the rebate check when I should?

Medicare Part D enrollees who hit the “donut hole” should expect to receive her check within 45 days. Your rebate may be delayed if Medicare doesn’t have information from your Medicare drug plan showing that you reached the coverage gap in time to include you in the next monthly mailing. You should call your Medicare drug plan to make sure all of your information has been sent to Medicare. If you don’t get your rebate check, contact Medicare. Individuals receiving Medicare Extra Help will not receive a rebate check. You can also check to make sure Social Security has your correct home address. Call 1-800-772-1213 or your local Social Security office. TTY users should call 1-800-325-0778.
