When Medicare or your plan denies coverage or payment, the notice starts a legal clock. Put the first deadline on your calendar, get clinical support from your provider, and file the right level-one request before you think about later levels. You cannot skip level one and go straight to a judge. The higher levels also have dollar minimums: for requests filed in 2026, Medicare.gov states $200 for an Office of Medicare Hearings and Appeals (OMHA) decision and $1,960 for federal district court judicial review.
Most people who lose an appeal had a decent argument. They missed the first deadline or mailed a letter to the wrong contractor.
Know which system you are in
Medicare’s appeals booklet (Publication 11525) lays out three tracks:
- Original Medicare (Parts A and B): five levels starting with a Medicare Administrative Contractor (MAC) redetermination.
- Medicare Advantage (Part C): five levels starting with a reconsideration from your plan, then an Independent Review Entity (IRE).
- Part D drug coverage: five levels starting with a redetermination from your plan, then an IRE.
The names of the levels shift a little, but the order is the same: plan or contractor first, then independent review, then OMHA, then Medicare Appeals Council, then federal court. This article focuses on Original Medicare detail because Medicare.gov publishes the fullest beneficiary walkthrough there, then flags Advantage/Part D differences.
Original Medicare Level 1: Redetermination by the MAC
Start with your Medicare Summary Notice (MSN). File by the date printed on the MSN. If you miss it, you may still get a decision if you show good cause (for example disability, illness, or accident that delayed filing).
You can file three ways:
- Complete the Redetermination Request Form and send it to the MAC address on the MSN, or
- Circle the disputed items on a copy of the MSN, explain why you disagree, include your name and Medicare Number, attach supporting records (doctor notes help), and mail to the claims address listed on the MSN, or
- Submit a written request with the elements Medicare.gov lists (identity, items/services and dates, why coverage should apply, representative paperwork if any).
The MAC generally decides within 60 days. Favorable results appear on a later MSN. Unfavorable results come as a Medicare Redetermination Notice.
Ask your provider for records before you file. A denial without clinical context is harder to reverse than one that includes the ordering physician’s rationale and relevant guidelines.
Level 2: QIC reconsideration
You have 180 days after the MAC decision letter or MSN (as Medicare.gov states for this step) to request reconsideration by a Qualified Independent Contractor (QIC) that did not decide level one.
File the Medicare Reconsideration Request Form to the QIC listed on your Medicare Redetermination Notice, or send a written request that includes identity, disputed items and dates, why you disagree, a copy of the redetermination notice, and any missing documentation the notice identified.
The QIC generally decides within 60 days. If you disagree, you typically have 60 days from the QIC decision to request level 3.
Level 3: OMHA decision (ALJ or on-the-record)
For 2026, the amount in dispute must be at least $200. That threshold is adjusted annually; contractor notices and CMS amount-in-controversy announcements confirm $200 for ALJ hearing requests filed on or after January 1, 2026 (up from $190 for 2025 filings).
You may request a hearing before an Administrative Law Judge or, in some cases, an on-the-record review without a hearing (Form OMHA-104 or a written waiver). Hearings are usually by phone or video; in-person hearings require a good reason found by the ALJ.
Follow the directions on the QIC’s Medicare Reconsideration Notice. Include why you disagree, dates of service, appeal numbers, and any new evidence, or explain when you will submit it.
If OMHA does not issue a timely decision, or you disagree with the decision, you generally have 60 days to move to level 4.
Level 4: Medicare Appeals Council
Follow the ALJ decision instructions. You may use the Council review request form or a written request that identifies the items, dates, the ALJ decision date, and what you dispute. The Council is part of the Departmental Appeals Board framework described in CMS appeals materials.
Level 5: Federal district court
For 2026, taking it to federal court requires at least $1,960 still in dispute. You may be able to combine claims to meet that amount. File within 60 days of the Council’s decision, following the directions in that decision letter. By this stage most people work with counsel; the right to seek review is still yours if the threshold and timing are met.
Fast appeals and hospital status changes
Separate from standard claim appeals, Medicare provides expedited processes when you are still receiving care and believe services are ending too soon (hospital discharge, SNF, home health, hospice contexts). Follow the notices the provider must give you; those notices list phone numbers and deadlines measured in hours or a few days, not months.
Hospital status changes from inpatient to outpatient observation can affect both hospital billing and skilled nursing eligibility under the 3-day rule. Medicare.gov describes appeal rights for certain status changes for inpatient admissions on or after January 1, 2009, including a fast appeal path while still hospitalized in qualifying situations. If SNF coverage is at risk because of observation labeling, treat status appeals as urgent.
Medicare Advantage and Part D differences (high level)
Per Publication 11525:
- Advantage: Level 1 is a plan reconsideration of an organization determination. Level 2 is an Independent Review Entity. Levels 3-5 align with OMHA, Appeals Council, and court, with amount-in-controversy rules that CMS also adjusts annually for Part C.
- Part D: Level 1 is a plan redetermination. Level 2 is an IRE. Then OMHA, Council, and court.
Always use the appeal instructions on your plan’s denial or coverage determination notice. Standard versus expedited drug determinations have different clocks. For payment denials after you received a service, the plan notice still controls where to send the request.
Practical filing habits that improve outcomes
- Copy every notice the day it arrives; photograph barcodes and deadlines.
- Put the Medicare Number and appeal number on every page.
- Attach clinical notes, orders, and relevant coverage criteria language from Medicare manuals or the plan Evidence of Coverage.
- Appoint a representative with the proper form if a family member or advocate will speak for you.
- Track 60-day and 180-day clocks on a calendar; a phone call to Medicare does not count as filing an appeal.
- If the amount is under the OMHA threshold, ask about aggregating related claims as CMS regulations allow when rules are met.

Frequently asked questions
What are the five appeal levels in Original Medicare?
Level 1 is a redetermination by the Medicare Administrative Contractor (MAC); Level 2 is reconsideration by a Qualified Independent Contractor (QIC); Level 3 is an OMHA decision (ALJ or on-the-record); Level 4 is Medicare Appeals Council review; Level 5 is federal district court. Medicare.gov and CMS Publication 11525 walk through that ladder.
What 2026 dollar thresholds apply at higher appeal levels?
For requests filed in 2026, Medicare.gov states at least $200 remaining in controversy for an OMHA decision and $1,960 for federal judicial review. Thresholds are adjusted annually. You may be able to combine related claims when rules allow.
How do Medicare Advantage and Part D appeals differ at the start?
Advantage Level 1 is a plan reconsideration of an organization determination, then an Independent Review Entity. Part D Level 1 is a plan redetermination, then an IRE. Higher levels then align with OMHA, the Appeals Council, and court. Always follow the instructions on your plan’s denial notice.
What is the most common way people lose an appeal?
Missing the first deadline or mailing a complaint letter to the wrong contractor, not lacking a solid clinical argument. Treat the denial notice as a timed legal document: calendar the deadline, gather provider support, and file level one correctly.
How do I file an Original Medicare Level 1 redetermination?
Use the Redetermination Request Form to the MAC address on the Medicare Summary Notice, or circle disputed items on a copy of the MSN with a written explanation and records, or send a written request with the identity and service details Medicare.gov lists. The MAC generally decides within 60 days.
What deadlines apply after Level 1?
You generally have 180 days after the MAC decision to request QIC reconsideration. After an unfavorable QIC decision you typically have 60 days to request OMHA review. Follow the dates printed on your notices rather than a blog summary.
What are fast appeals for?
Expedited processes apply when you are still receiving care and believe services are ending too soon, as in hospital discharge, SNF, home health, or hospice contexts. Those notices list phone numbers and deadlines measured in hours or a few days. Hospital status changes from inpatient to observation can also trigger urgent appeal rights tied to SNF eligibility.
Can I skip Level 1 and go straight to a judge?
No. The structured ladder requires the early levels first. Skipping level one is not how the process works, and higher levels also impose amount-in-controversy thresholds.
What if the amount in controversy is under the OMHA threshold?
Ask about aggregating related claims when CMS rules allow. If aggregation is not available, you may be limited to the levels whose thresholds you meet. Confirm on the current year’s amount-in-controversy announcements.
