Part D LEP Reconsideration Request: How to Appeal a Part D Late Enrollment Penalty

Why Part D Penalty Appeals Go to a Different Place

If you've been assessed a Part D late-enrollment penalty, you don't appeal to the Social Security Administration. Part D penalty reconsiderations are handled by an independent review entity contracted by CMS — currently C2C Innovative Solutions, Inc. This trips people up because Part B penalty appeals go to SSA, but Part D operates on a completely separate track.

The penalty itself: 1% of the national base beneficiary premium ($38.99 in 2026) multiplied by the number of full months you went without creditable drug coverage. It's permanent, added to your Part D premium every month, and it adjusts upward each year as the base premium changes.

The 60-Day Filing Window

You have 60 days from receiving the penalty notice to file your reconsideration request. The notice comes from your Part D plan, not from CMS directly. It tells you the penalty amount and the coverage gap period that triggered it.

The 60-day clock is strict. If you miss it, you can still file with a good-cause explanation (hospitalization, a family emergency, or never receiving the notice), but approvals after the deadline are much harder to get.

How to File the Reconsideration

Get the form. The Part D LEP Reconsideration Request Form is available on the CMS website. Search for "Part D LEP Reconsideration Request Form" or download it directly from the CMS appeals and grievances page for prescription drug coverage.

Fill out the form. It asks for:

• Your name, Medicare number, and date of birth
• Your current Part D plan name and contract number (on your plan's member ID card)
• The period of alleged non-creditable coverage — the dates CMS says you didn't have qualifying drug coverage
• Your explanation of why the penalty should be removed

Write a supporting statement. The form has a section for your explanation, but space is limited. Attach a separate letter that lays out your case clearly:

1. State the specific period the penalty covers
2. Explain what drug coverage you had during that period
3. Identify the source of that coverage (employer name, plan name, plan sponsor)
4. Confirm that the coverage was creditable (i.e., it met Medicare's actuarial standard)
5. Explain why there may be a record gap — employer closed, notice was lost, plan changed administrators

What Evidence to Include

The strongest reconsideration requests include documentation for every month of the disputed period:

• Annual creditable coverage notices from your employer or plan sponsor (the letter they're required to send before October 15 each year)
• A letter from your former employer confirming their drug coverage was creditable during the disputed period
• Benefits enrollment confirmations showing your plan included prescription drug coverage
• Summary Plan Descriptions that reference the creditable coverage determination
• Prescription drug claims or pharmacy receipts showing you actively used the plan's drug benefit
• VA health records if you had VA drug coverage during the gap
• TRICARE benefit statements if you were covered under military benefits

If you can't get the creditable coverage notice because your employer is out of business, say so explicitly in your supporting statement and provide whatever alternative documentation you have.

What Happens During the Review

C2C Innovative Solutions reviews your request independently of your Part D plan. They may contact your former employer or plan sponsor directly to verify coverage. The review typically takes 30–60 days, though complex cases can take longer.

You must keep paying the penalty while the appeal is pending. This is federal law, not a suggestion. If you stop paying your Part D premiums (including the penalty amount), your plan can disenroll you for nonpayment. If the reconsideration is decided in your favor, the penalty is removed and any overpaid amounts are credited back — usually as an offset against future premiums.

If the Reconsideration Is Denied

A denial isn't the end. You can escalate through the Medicare appeals process:

1. Reconsideration (what you just filed) — reviewed by C2C Innovative Solutions
2. ALJ hearing — heard by an Administrative Law Judge if the amount in controversy meets the threshold
3. Medicare Appeals Council review
4. Federal district court — for cases exceeding the judicial review threshold

Each level has its own deadlines and requirements for filing. The further you escalate, the more formal the process becomes and the more likely you'll want professional help.

Avoiding This Problem Next Time

The Part D penalty exists because of a gap in creditable coverage. Two habits prevent it:

Save every creditable coverage notice you receive. File them with your tax records. If your coverage changes mid-year, make sure you get an updated notice.

When you lose creditable drug coverage, enroll in a Part D plan within 63 days. The 63-day window is your grace period. As long as you secure new creditable coverage within 63 consecutive days of losing the old coverage, no penalty accrues.

The Medicare Late-Enrollment Penalties and Special Enrollment guide includes Part D appeal letter templates and a creditable coverage evidence checklist to streamline the reconsideration process.
