Educational only. I am not an actuary, attorney, or claims advocate. This article summarizes the Original Medicare appeals path and notes where Advantage and Part D differ, using Medicare.gov and CMS publications. Your denial notice controls deadlines and addresses.

Treat the denial notice as a deadline
When Medicare or your plan denies coverage or payment, treat the notice as a timed legal document: calendar the first deadline, gather clinical support from your provider, and file the correct level-one request before you debate later levels. Skipping level one to “go straight to a judge” is not how the process works. Dollar thresholds for higher levels are real; 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 lose appeals by missing the first deadline or by mailing a complaint letter to the wrong contractor, not by lacking a solid argument.
Know which system you are in
Publication 11525 (Medicare Appeals) separates 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 level names shift slightly, but the idea 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). Medicare.gov: 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).
Ways to file:
- 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)
Medicare.gov: for 2026, the amount in controversy 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
Medicare.gov: for 2026, judicial review requires at least $1,960 remaining in controversy. 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)
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; “I called Medicare” is not a filed appeal.
- If the amount is under the OMHA threshold, ask about aggregating related claims as CMS regulations allow when rules are met.
File on time first
Coverage denials are appealable through a structured ladder. In Original Medicare that ladder is MAC redetermination, QIC reconsideration, OMHA, Appeals Council, then federal court. For 2026, expect a $200 minimum for OMHA and $1,960 for judicial review, as Medicare.gov states. Advantage and Part D start at the plan, then move to an independent entity before the same higher levels. File on time, to the address on the notice, with clinical evidence. Missing the first deadline ends the appeal before the argument starts.
