Yes, you can appeal a Medicare Part D drug denial, and you should start right away. Begin with a Level 1 redetermination within 65 days of the denial notice. If waiting could seriously harm your health, ask your prescriber to request an expedited review, which starts a 72-hour clock.
TL;DR:
- Filing a Level 1 redetermination within 65 days is essential; expedite the process if your health could be seriously compromised.
- Gather detailed supporting evidence, including prescriber statements and proof of payment, to strengthen your appeal at each level.
- Request expedited review by clearly stating health risks and follow up with written requests, as delay could jeopardize your case.
- Be aware of specific deadlines, filing windows, and the importance of consistent documentation to avoid procedural dismissals.
- If the initial appeal fails, escalate to the next review level promptly and consider legal or advocacy assistance for complex or prolonged disputes.

A 48 to 72 Hour Checklist for What to Do After a Denial
The first few days after a denial matter most. Acting quickly protects your filing deadline and gives your prescriber time to add the clinical detail that strengthens your case.
- Read the denial notice carefully and circle the printed deadline: you generally have 65 calendar days to file a Level 1 redetermination, and later levels typically allow the filing window stated on the notice from the next notice.
- Call your Part D plan to confirm what kind of denial this is (a coverage decision, a formulary exception, or a payment denial) and ask how the plan accepts appeal requests, whether by phone, fax, or mail.
- Ask your prescriber for a written supporting statement explaining why the requested drug is necessary and why formulary alternatives will not work; if your situation is urgent, ask the prescriber to say so clearly.
- If you already paid out of pocket, gather the pharmacy receipt now and start drafting a written payment request to attach alongside the prescriber’s statement.
Every one of these steps costs you little time but buys you options later. A missed deadline at this stage can end an otherwise strong case before it starts.
Step-by-Step: Levels 1 Through 5 Explained
Part D appeals move through five formal levels, and each one has its own reviewer, filing window, and decision clock. Knowing the sequence in advance keeps you from losing time figuring out where to send the next request.
Level 1, redetermination, is handled by your own Part D plan. File within 65 calendar days of the initial denial notice. The plan must decide as quickly as the enrollee’s health requires, but no later than the expedited or standard timeframes specified by Medicare regulations, with longer limits for payment disputes, according to Medicare’s official appeals guidance.
Level 2, reconsideration, goes to the Part D Independent Review Entity (IRE), sometimes called the Qualified Independent Contractor. You generally have 65 calendar days from the plan’s redetermination notice to file, and the IRE must decide within 72 hours expedited or 7 days standard. If an exception request is missing the prescriber’s supporting statement, the IRE reconsideration process allows up to a 14-day extension.
Level 3, the Office of Medicare Hearings and Appeals (OMHA) ALJ hearing, requires filing within the stated filing window of the IRE’s unfavorable notice. This level also involves an amount-in-controversy (AIC) threshold, which the CMS Part D appeals flowchart outlines for 2026, along with the option to waive an oral hearing in favor of an on-the-record review.
Level 4, the Medicare Appeals Council, and Level 5, federal district court, apply when earlier decisions remain unfavorable and, for court review, when the dispute meets a higher AIC threshold. Each stage has its own filing window, generally allowing about two months from the prior notice.
When to Request Expedited Review and How to Document Urgency
Expedited review exists to speed decisions when waiting could seriously jeopardize your life, health, or ability to regain maximum function. A cancer patient waiting on a chemotherapy-adjacent drug or someone facing a dangerous gap in insulin coverage both fit this standard.
- Call your plan directly and request expedited review, then follow up with a written or faxed statement from your prescriber describing the specific health risk.
- The plan or IRE must give you an initial verbal notice quickly, often within hours, and should follow with written confirmation within a few days.
- Keep a log of every call: date, time, name of the representative, and any reference number given.
Pro Tip: Ask your prescriber to put the words “expedited review requested due to risk of serious harm” directly in the fax or letter, since vague urgency language can cause plans to default to standard processing.
Exactly What Evidence to Collect and What Your Prescriber Should Write
A thin file is the most common reason a strong case loses at Level 1. Build your record as if a stranger will read it months from now with no other context.
- Keep the original denial notice, the plan’s Evidence of Coverage or formulary page showing the drug’s tier, and any prior authorization paperwork.
- Save prior treatment notes, relevant lab results, and the pharmacy receipt if you paid out of pocket.
- Hold onto every fax confirmation, email, and dated letter, since these timestamps matter if you need to prove you filed on time.
Ask your prescriber’s office to write a statement that names the diagnosis, lists therapies already tried and why they failed or caused side effects, and explains specifically why covered alternatives are inadequate for your case. Under CMS guidance on coverage determinations, the adjudication clock for exception requests does not start until the plan or IRE actually receives this statement, so a delayed fax can quietly cost you days.
Pro Tip: Keep a simple call log with names, dates, and reference numbers; it becomes your strongest proof of a timely filing if a plan later disputes when you submitted your appeal.
How to Request Payment or Reimbursement for an Out-of-Pocket Drug
If you already paid for a medication the plan should have covered, you file a payment request rather than a standard coverage appeal. Submit a written statement, or the plan’s own model form if one is offered, along with your pharmacy receipt.
- Attach the original pharmacy receipt showing what you paid and when.
- Include your prescriber’s supporting statement and any prior denial or prior authorization letters tied to the claim.
- Track the date you submit the request, since plans generally must issue a payment decision within the required timeframe defined by regulations.
If the plan misses that 14-day window, you have grounds to escalate the same way you would an unfavorable coverage decision.
How to Escalate Beyond the Plan: OMHA Hearings, Council Review, and Court
When the IRE issues an unfavorable reconsideration, you can request an ALJ hearing through OMHA within the filing window stated on the notice, provided your case meets the amount-in-controversy threshold for 2026. You may also waive the oral hearing and ask for an on-the-record review instead, which can move faster for straightforward disputes.
- File your ALJ hearing request using OMHA’s forms, and decide whether you want to appear by phone, video, or in person.
- The Medicare Appeals Council reviews ALJ decisions next, also within its specified filing deadline from the prior notice.
- Federal district court review becomes available only after Council review and if the dispute meets the necessary amount-in-controversy threshold.
These later levels can take months, and the paperwork grows more technical. This is the point where many beneficiaries bring in a patient advocate, a local legal aid organization, or an attorney familiar with Medicare appeals.
Avoid These Common Mistakes That Derail Part D Appeals
Most lost appeals fail for procedural reasons, not medical ones. A few repeatable habits fix nearly all of them.
- Missing the 65-day or 60-day filing windows because the notice sat unopened for a week.
- Filing without a prescriber statement, which can stall the adjudication clock before it even starts.
- Confusing a grievance, which is a complaint about service, with a formal appeal of a coverage decision.
- Losing track of correspondence because nothing was dated or filed consistently.
Pro Tip: Set a calendar reminder the day you receive any denial notice, tied to the exact date printed on the letter, not the day you opened the envelope.
Free help exists if your case gets complicated: State Health Insurance Assistance Program (SHIP) counselors, the Medicare.gov help line, and local legal aid offices all assist with appeals at no cost.
Our Perspective: How We Help and When to Loop in a Local Agent
Appeals that move fastest are typically the ones where the prescriber’s office responds within a day or two, since that single step often determines whether the 72-hour clock even starts on time. A consultation can help you check deadlines, review your paperwork for gaps, and point you toward SHIP or legal aid when a case needs to go to OMHA.

FAQ
What is the appeal process for Medicare Part D plans?
The process has five levels: a plan redetermination, an IRE reconsideration, an OMHA ALJ hearing, Medicare Appeals Council review, and federal court. You start at Level 1 by filing with your own plan within 65 days of the denial notice.
What percentage of Medicare appeals are successful?
CMS and OMHA do not publish a single consolidated success rate across all five appeal levels, so we cannot state one figure as the answer. What official guidance does confirm is that a complete record, including a prescriber’s supporting statement, is central to how each level evaluates a case.
How can I appeal a Part D penalty?
A late enrollment penalty dispute follows a different track than a drug coverage denial, and it generally starts with a reconsideration request to your plan or the Social Security Administration rather than the five-level coverage appeals process described here. Contact your plan directly for the specific reconsideration request form tied to penalty disputes.
What is the time limit for appealing a Medicare decision?
For Part D, you have 65 calendar days from the date on the denial notice to file a Level 1 redetermination, based on the official Medicare appeals timeline. Later levels, including the IRE reconsideration and OMHA hearing, generally allow the filing window stated on the notice from the prior unfavorable notice.
