medicare appeal levels are the five stages a denied Medicare claim can travel through, and right now you are probably standing at the start of them with a notice in your hand and a date circled on it. Maybe a Medicare Summary Notice came in the mail marked “not covered.” Maybe an Advantage plan refused a rehab stay. Maybe a pharmacy turned your parent away at the counter. The system is not asking you to argue well.

It is asking you to file on time, in writing, at the correct step. Each step has its own notice, its own decider, and its own deadline in days. This guide walks the five stages in order, names the forms, and points to the free phone numbers that cost you nothing to call.
What “medicare appeal levels” Actually Means
The medicare appeal levels are a ladder built into federal law. You start at the bottom. You cannot skip a rung. Each level is decided by someone further from the party that told you no.
Level 1 goes back to the entity that made the first decision. Level 2 goes to an independent contractor. Level 3 is a hearing at the Office of Medicare Hearings and Appeals. Level 4 is the Medicare Appeals Council. Level 5 is federal district court.
The path differs by the part of Medicare you have. Original Medicare, Medicare Advantage and Part D each have their own Level 1 and Level 2. From Level 3 up, the medicare appeal levels merge into one shared track. Medicare.gov explains the general appeals structure here.
The Deadline You Cannot Miss
For Original Medicare, the clock is 120 calendar days. It runs from the date you receive the Medicare Summary Notice (MSN) showing the denial. Miss it and you must show good cause under 42 CFR 405.942(b), which is not guaranteed.
For a Medicare Advantage or Part D denial, the first clock is much shorter: 60 calendar days from the plan’s denial notice. Confirm the exact date printed on your own notice, because the notice date and your receipt date can differ.
Here is how the medicare appeal levels line up for Original Medicare:
| Level | What it is called | Who decides | Form | Deadline to file |
|---|---|---|---|---|
| 1 | Redetermination | Medicare Administrative Contractor (MAC) | CMS-20027 | 120 days from the MSN |
| 2 | Reconsideration | Qualified Independent Contractor (QIC) | CMS-20033 | 180 days from the redetermination notice |
| 3 | ALJ hearing | Administrative Law Judge or attorney adjudicator at OMHA | OMHA-100 | 60 days from the QIC notice |
| 4 | Council review | Medicare Appeals Council (Departmental Appeals Board) | DAB-101 | 60 days from the ALJ decision |
| 5 | Judicial review | Federal district court judge | Court complaint | 60 days from the Council decision |
Two dollar thresholds also apply. For requests filed on or after January 1, 2026, the amount in controversy is $200 for a Level 3 hearing and $1,960 for federal court. CMS publishes these figures annually in the Federal Register.
How to Start a Medicare Appeal Levels
Step one: read the notice and find the denial reason code and the date. Everything in the medicare appeal levels keys off that date.
Step two: for Original Medicare, complete the Medicare Redetermination Request Form, CMS-20027. You may instead circle the disputed items on the MSN, sign it, and mail it. Send it to the MAC address printed on the notice itself.
Step three: if Level 1 is denied, file the Medicare Reconsideration Request Form, CMS-20033, with the QIC named in your redetermination letter. CMS describes the Level 2 reconsideration here.
Step four: for Level 3, file form OMHA-100 with the office listed on the QIC notice. OMHA publishes filing tips. For Level 4, file form DAB-101 with the Medicare Appeals Council.
If you are in a Medicare Advantage plan, Level 1 is a plan reconsideration filed with the plan. If the plan upholds its denial on a service request, the file goes to the Independent Review Entity automatically. For Part D, Level 1 is a plan redetermination and Level 2 is the Part D IRE. Medicare.gov covers drug plan appeals here.
Send everything by a method that produces a receipt. Keep a copy of every page you mail.
What to Put in the File
Put in the denial notice itself. Add the itemized bill, the claim number, and the Medicare Beneficiary Identifier exactly as printed. Add the dates of service in dispute.
The document that moves the medicare appeal levels most often is a letter from the treating physician. It should say what the condition is, what the item or service does for that condition, and why the alternatives are inadequate.
Ask the doctor to reference the coverage rule the denial cited and respond to it directly. Ask for chart notes, test results, and therapy notes that support the letter. Number your pages and include a one-page cover index listing what is enclosed.
If you want someone to speak for you, file form CMS-1696, Appointment of Representative. Without it, the decider generally cannot discuss the case with a family member.
If the First Level Says No
A Level 1 denial is common and is not the end. Level 2 moves the file to a Qualified Independent Contractor, an outside reviewer with its own physicians. You have 180 days in Original Medicare and 60 days in most plan appeals.

Free help exists at every rung of the medicare appeal levels. Call 1-800-MEDICARE (1-800-633-4227), free, 24 hours a day. Call your State Health Insurance Assistance Program at 1-877-839-2675 for free one-on-one counseling.
If the dispute is a hospital discharge you believe is too soon, it goes to the BFCC-QIO instead. You should receive An Important Message from Medicare (CMS-10065) within two days of admission. Call the QIO number on that notice by midnight of the planned discharge day. Medicare.gov explains fast appeals here.
The hospital must then give you a Detailed Notice of Discharge (CMS-10066) by noon the day after the QIO notifies it. The QIO is free to call. The Medicare Rights Center and the Center for Medicare Advocacy also publish free self-help packets.
Mistakes That Sink a Medicare Appeal Levels
Calling instead of filing. A phone call to the plan or the contractor does not start the clock in the medicare appeal levels. Only a written, dated request does.
Waiting for the bill to be resolved first. The deadline runs from the notice date, not from when billing sorts itself out.
Sending the paperwork to the wrong address. Each level lists its own filing address on its own notice. Use that one, not the address from the previous level.
Filing without the doctor’s letter and then having nothing new to add later. Build the record early, because the file assembled at Level 3 is largely what the Council reviews at Level 4.
Letting the Appointment of Representative lapse. It generally must be filed for the appeal and can expire, so confirm its status with the decider handling your level.
Frequently Asked Questions
How long do the medicare appeal levels take from start to finish?
A Level 1 redetermination decision is generally issued within 60 days of receipt. Level 2 has its own statutory timeframe, and Level 3 wait times have historically run far longer. Ask the office handling your level for its current processing time.
Do I need a lawyer?
No representative is required at any level. Many people use a free SHIP counselor or a Medicare Rights Center helpline counselor instead. This article describes the process only and is not legal advice.
What if I missed the 120-day deadline?
You may request an extension for good cause under the regulation at 42 CFR 405.942(b). Explain the reason in writing on the form. Whether good cause is accepted is decided case by case, so confirm your options with 1-800-MEDICARE or your SHIP.
Is the process different for Medicare Advantage?
Yes at the first two rungs. In an Advantage plan, the medicare appeal levels begin with the plan itself, usually within 60 days, and a denied service request then goes to a federal Independent Review Entity. From Level 3 upward the track is the same as Original Medicare, and expedited timeframes apply when waiting could seriously harm health.
