If you were without Part D or creditable drug coverage for more than 63 days while eligible for Medicare , you may face a Part D late enrollment penalty (LEP). The purpose of the LEP is to encourage Medicare beneficiaries to maintain adequate drug coverage. The penalty is 1% of the national base beneficiary premium ($34.70 in 2024) for every month you did not have Part D or certain other types of drug coverage while eligible for Part D. This amount is added to your monthly Part D premium.

Eliminating the Part D LEP

For most people, you have to pay the LEP as long as you are enrolled in the Medicare prescription drug benefit . There are some exceptions:

• If you receive Extra Help, your penalty will be permanently erased
• If you are under 65 and have Medicare, your LEP will end when you turn 65
• If you qualify for a state pharmaceutical assistance program (SPAP), it may pay your penalty for you

Appealing the LEP

Everyone has the right to file an appeal with C2C Innovative Solutions regarding their LEP determination. C2C Solutions is the company contracted by Medicare to handle these appeals. You can appeal the penalty (if you think you were continuously covered) or its amount (if you think it was calculated incorrectly). You should complete the appeal form you received from your plan, attach any evidence you have, and mail everything to:

C2C Innovative Solutions Toll free fax: (833) 946-1912
Part D LEP Reconsiderations Customer Service: 833-919-0198
PO Box 44165
Jacksonville, FL 32231-4165

If you don’t have an appeal form from your plan, you can also use this form.

Unfortunately, being unaware of the requirement to have prescription drug coverage is unlikely to be a successful basis for your appeal. However, the following are good reasons to appeal and may result in the elimination or reduction of your penalty:

• You have Extra Help
• You had creditable drug coverage during some or all of the time period in question
  • Call your former plan and ask for a letter proving that you were enrolled in creditable drug coverage. Make sure to attach this letter to your appeal form. Your employer or union may also be able to confirm the fact that you had creditable drug coverage.

  The appeal deadline is 60 days from the date you received the letter informing you about the penalty. If you miss this deadline, you can write a letter explaining why you had good cause, or a good reason—like serious illness—that prevented you from appealing on time. Attach this letter to your appeal. Once your appeal is submitted, you can expect a determination from C2C Innovative Solutions within 90 days. In the meantime, pay the LEP to your plan along with your premium. If your appeal is successful, your plan has to pay you back for the LEP payments you made while your appeal was pending.
