medicare part d appeal is the phrase you need the moment the pharmacist slides the prescription back across the counter. The drug your doctor picked is not covered. Maybe the plan wants a cheaper drug tried first. Maybe the drug is off the formulary. Maybe the quantity is capped at fewer pills than the prescription says. You are standing at a counter with a sick family member and no medication in your hand.

That is the situation this guide is written for. A medicare part d appeal has fixed steps, named forms, named deciders and hard deadlines. Miss a deadline and you may have to start over. Meet them and the case climbs a five-level ladder that ends in federal court. What follows is that ladder, in order, with the notice you receive at each rung and the number of days you get.
What “medicare part d appeal” Actually Means
A medicare part d appeal is a formal request to reverse a coverage decision your drug plan already made. It is not a complaint. Complaints about service, wait times or rudeness are called grievances, and they run on a separate track that does not get you the drug.
Before you can appeal anything, the plan has to say no first. That first decision is called a coverage determination. If you are asking the plan to bend a formulary rule — cover a non-formulary drug, waive step therapy, lift a quantity limit, or move a drug to a cheaper tier — you are asking for an exception, which is one kind of coverage determination.
The slip you get at the pharmacy counter is not the denial. It is Form CMS-10147, “Medicare Prescription Drug Coverage and Your Rights.” It only tells you to contact your plan. You cannot appeal from that notice alone.
The real denial arrives on Form CMS-10146, the Notice of Denial of Medicare Prescription Drug Coverage. Your medicare part d appeal clock starts on the date printed on that notice. See CMS on coverage determinations for the rule.
The Deadline You Cannot Miss
Sixty-five calendar days. That is your window to file a Level 1 redetermination, counted from the date on the CMS-10146 denial notice. The plan must accept the request in writing, and most accept it by phone and fax as well.
Every level after that gives you 60 calendar days, counted from the date of the decision notice you are appealing. Late filings can sometimes be accepted for good cause. Do not build your plan around that.
| Step | Notice or form | Who decides | Your deadline to file | Their deadline to decide |
|---|---|---|---|---|
| Coverage determination / exception request | Model Request for Medicare Prescription Drug Coverage Determination | Your Part D plan | No fixed deadline | 72 hours standard; 24 hours expedited |
| Level 1 — Redetermination | Request for Redetermination of Medicare Prescription Drug Denial (denial arrives on CMS-10146) | Your Part D plan, by different staff | 65 calendar days from the coverage determination notice | 7 calendar days standard; 72 hours expedited |
| Level 2 — Reconsideration | Form CMS-20031 | Independent Review Entity (Part D IRE), currently C2C Innovative Solutions | 60 calendar days from the redetermination notice | 7 calendar days standard; 72 hours expedited |
| Level 3 — Hearing | Form OMHA-100 | Administrative Law Judge or attorney adjudicator at OMHA | 60 calendar days from the IRE notice | 90-day goal |
| Level 4 — Council review | Form DAB-101 | Medicare Appeals Council (Departmental Appeals Board) | 60 calendar days from the OMHA decision | 90-day goal |
| Level 5 — Judicial review | Civil complaint | U.S. District Court | 60 calendar days from the Council decision | No set timeframe |
Two dollar thresholds apply late in a medicare part d appeal. For requests filed on or after January 1, 2026, Level 3 requires at least $200 still in dispute and Level 5 requires $1,960. Confirm the figure that applies to your year with 1-800-MEDICARE before you file.
How to Start a Medicare Part D Appeal
Step 1. Ask the plan for a coverage determination. Call the number on your plan card or use the CMS model coverage determination request form. You, your prescriber, or an appointed representative may file it.
Step 2. Get the prescriber’s supporting statement. For any exception request, the plan cannot decide until the prescriber explains why the preferred drug will not work or would harm the patient. The 72-hour clock effectively runs from receipt of that statement.
Step 3. Ask for expedited handling if waiting is risky. An expedited request cuts the coverage determination to 24 hours and a Level 1 medicare part d appeal to 72 hours. If the prescriber supports the request, the plan must grant it.
Step 4. Read the CMS-10146 denial. It states the reason, the appeal address and the filing deadline. Photograph it. Note the date.
Step 5. File the Level 1 redetermination. Use the model Request for Redetermination of Medicare Prescription Drug Denial, downloadable from the CMS Part D appeals forms page. Send it to the address or fax on the denial notice, not to Medicare.
Step 6. Keep proof of filing. Fax confirmation, certified mail receipt or a portal timestamp. If the plan misses its own decision deadline, the case is supposed to move to the IRE automatically. Details are on the CMS redetermination page.
What to Put in the File
The prescriber’s letter is the document that moves cases. A useful letter names the diagnosis, names the drug and dose, and states in plain clinical terms why the plan’s preferred alternative is not appropriate for this patient.
It should list what was already tried, when, at what dose, and what happened — the failure, the side effect, the allergy, the contraindication. Dates matter more than adjectives.
Attach the supporting paper: pharmacy printouts showing prior fills, chart notes, lab results, hospital records tied to the failed alternative, and the CMS-10147 counter notice if you have it.
If you are appealing for a parent or spouse, file Form CMS-1696, Appointment of Representative, at the same time. Without it, the plan may refuse to speak with you.
Keep a one-page timeline at the front: date of the prescription, date of the counter notice, date of the CMS-10146, date you filed. Adjudicators read the timeline first.
If the First Level Says No
Level 2 leaves the plan entirely. An Independent Review Entity under contract to CMS — currently C2C Innovative Solutions — reviews the case fresh. File Form CMS-20031 within 60 calendar days of the redetermination notice.

Mistakes That Sink a Medicare Part D Appeal
Treating the pharmacy slip as the denial. CMS-10147 is a notice of rights, not a decision. Nothing is appealable until the plan issues a coverage determination.
Filing a grievance instead of a medicare part d appeal. A grievance about poor service does not produce the drug and does not stop the 65-day clock.
Letting the prescriber’s statement lag. On exception requests the plan can hold the file until that statement arrives. Days spent waiting are days lost.
Skipping the expedited request. Families often accept the standard timeline when the prescriber would have supported a 24-hour or 72-hour review.
Sending paperwork to the wrong place. Level 1 goes to the plan. Level 2 goes to the IRE. Level 3 goes to OMHA. Mail sent to the wrong office still ages against your deadline.
Frequently Asked Questions
Can I get the drug while the appeal is pending?
Sometimes. New enrollees and members facing a mid-year formulary change are generally entitled to a temporary transition fill, commonly a 30-day supply. Ask your plan directly what transition supply your specific plan provides, and confirm the terms in your Evidence of Coverage.
Who can file on the member’s behalf?
The enrollee, the prescribing physician, or a representative appointed on Form CMS-1696. A prescriber may request a coverage determination and an expedited review without the appointment form. A family member generally needs the form on file.
What if I already paid cash for the drug?
You can request reimbursement through the same process. Payment requests use a longer standard timeframe than requests for the drug itself, and expedited handling is not available for payment. Attach the pharmacy receipt showing the amount paid.
Does a denial at Level 2 end the medicare part d appeal?
No. Levels 3, 4 and 5 remain, each with a 60-day filing window, though Levels 3 and 5 carry dollar minimums. Nothing here predicts how any case will be decided; confirm your own deadlines and options with your plan, 1-800-MEDICARE or your SHIP at Medicare.gov’s drug plan appeals page.
Key Takeaways: Medicare Part D Appeal
- The clock starts with the notice. Every medicare part d appeal deadline runs from the date on the letter, not the day you read it.
- Appeals are free. Filing a medicare part d appeal costs nothing, and asking does not affect your other Medicare coverage.
- The doctor’s letter is the evidence. A medicare part d appeal usually turns on a physician stating why the care is medically necessary.
- Ask for it in writing. Phone calls vanish; a medicare part d appeal request on paper, sent with tracking, is what survives.
- Level one is not the end. A medicare part d appeal has five levels, and the later ones overturn denials far more often than people expect.
