Medicare Advantage Appeal Process — Complete 5-Level Guide
If your Medicare Advantage plan denied a claim, Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization, or coverage decision, you have the right to appeal — all the way to federal court if necessary. The Medicare Advantage appeals process is a five-level ladder defined by CMS, and understanding each level can mean the difference between paying out of pocket and getting the care your doctor ordered.
This guide walks through every level, with timelines, tips, and strategies for beneficiaries who are ready to fight back.
Overview: The 5-Level MA Appeals Ladder
| Level | Who Reviews | Standard Timeline | Expedited Timeline |
|---|---|---|---|
| 1 | Your MA plan | 60 days (claims) / 30 days (PA) | 72 hours |
| 2 | MAXIMUS (external) | 60 days | 72 hours |
| 3 | ALJ (OMHA) | Varies | 10 days |
| 4 | Medicare Appeals Council | Varies | N/A |
| 5 | Federal District Court | Varies | N/A |
Each level has specific filing deadlines, documentation requirements, and dollar thresholds. Missing a deadline can forfeit your right to that level of review.
Before You Appeal — Understand What You're Appealing
The Medicare Advantage appeals process covers several types of decisions:
- Prior authorization denials: The plan refused to pre-approve a service, procedure, or equipment.
- Post-service claim denials: You received care, submitted a claim, and the plan denied payment.
- Ongoing service termination: The plan is ending coverage for a service (SNF, home health, inpatient) while you are still receiving it.
- Coverage amount disputes: The plan approved a service but at a lower rate or for fewer days than needed.
Your first step before appealing is to get the denial in writing. You are entitled to a written EOB)" class="auto-link">Explanation of Benefits (EOB) or Notice of Denial for every adverse decision. The denial notice will state the reason and your appeal rights.
Level 1 — Plan Internal Reconsideration
Who decides: Your Medicare Advantage plan (must be reviewed by someone not involved in the original decision)
Filing deadline: Within 60 days of the denial notice for claims; within 60 days for PA appeals
Decision timelines:
- Standard claims: 60 calendar days
- Standard prior authorization: 30 calendar days
- Expedited (urgent): 72 hours
How to file: Mail, fax, or online portal as directed in your denial notice.
What to include:
- Copy of the denial notice
- Letter of medical necessity from your treating physician, specifically rebutting the denial reason
- Supporting clinical records (diagnosis, treatment history, test results, specialist notes)
- References to Original Medicare coverage standards (NCDs, LCDs) if applicable
- Clear statement if requesting expedited review, with explanation of urgency
Key strategy: Address every specific reason the plan cited for denial. Generic appeals are easy to deny. A focused, clinically specific appeal with strong physician support is much harder to uphold.
If you win: The plan must authorize or pay for the service.
If you lose: You receive a written reconsideration decision and information on how to proceed to Level 2.
Level 2 — MAXIMUS External Independent Review: Complete Guide" class="auto-link">External Review
Who decides: MAXIMUS Federal Services, an independent organization contracted by CMS
Filing deadline: Within 60 days of receiving the Level 1 denial
Decision timelines:
- Standard: 60 calendar days
- Expedited: 72 hours
How to file: Follow the instructions in your Level 1 denial letter. Contact MAXIMUS directly at 1-855-MA-MAXIMUS (1-855-626-2948).
What makes MAXIMUS different: MAXIMUS reviewers are not employed by your MA plan. They must apply Original Medicare coverage standards — not the plan's proprietary clinical criteria. This means arguments that didn't work at Level 1 may succeed at Level 2, particularly when the plan's criteria were more restrictive than Original Medicare's.
Success rates: MAXIMUS overturns a meaningful percentage of MA plan decisions, particularly for skilled nursing, home health, and medical device denials. Do not skip this step.
If you win: The plan must implement the MAXIMUS decision. MAXIMUS decisions in your favor are binding on the plan.
If you lose: You receive a written decision and instructions for Level 3.

Level 3 — Administrative Law Judge (ALJ) Hearing
Who decides: An ALJ at the Office of Medicare Hearings and Appeals (OMHA)
Filing deadline: Within 60 days of receiving the Level 2 decision
Dollar threshold: The disputed amount must meet a minimum threshold (currently approximately $180) to request an ALJ hearing. If your dispute is below this amount, you may not be able to access Level 3.
Decision timeline: ALJ decisions typically take several months; expedited hearings may be available for urgent matters (approximately 10-day timeline).
How to file: Submit a request to OMHA. Your Level 2 denial will include OMHA contact information.
What to know:
- You may request an in-person, telephone, or video hearing.
- You can submit additional evidence at this level.
- Consider whether legal representation is helpful — patient advocacy organizations or attorneys who specialize in Medicare can be valuable at this level.
- ALJ hearings are more formal than plan-level appeals but are accessible to non-attorneys.
Success rates: ALJ hearings have historically produced favorable outcomes for beneficiaries at a higher rate than earlier levels, partly because many plans and contractors do not vigorously defend smaller cases at this level.
Level 4 — Medicare Appeals Council
Who decides: The Medicare Appeals Council (a federal administrative body)
Filing deadline: Within 60 days of receiving the ALJ decision
Dollar threshold: No separate dollar threshold at this level.
How to file: Submit a request to the Medicare Appeals Council (part of the U.S. Department of Health and Human Services' Departmental Appeals Board).
What to know: The Appeals Council reviews the ALJ's record and decision for legal and procedural errors. It does not typically conduct a new evidentiary hearing. Legal representation becomes more important at this level.
Level 5 — Federal District Court
Who decides: A U.S. Federal District Court
Filing deadline: Within 60 days of the Medicare Appeals Council decision
Dollar threshold: A higher dollar threshold applies (currently approximately $1,830 or more, adjusted annually).
What to know: Federal court is the final step. Beneficiaries rarely reach this level for routine coverage disputes, but it has produced landmark decisions that protect all Medicare beneficiaries — including Jimmo v. Sebelius (maintenance therapy coverage) and other precedent-setting cases. Legal representation is essential.
Expedited vs. Standard Appeals — Choosing the Right Track
You can request expedited review at Levels 1 and 2 (and sometimes Level 3) when your health condition requires a faster decision. To qualify for expedited review:
- Your treating physician must indicate that waiting the standard time would seriously jeopardize your health.
- Or, in cases of discharge from a hospital, SNF, or home health, the timing of the discharge itself triggers expedited options.
Always request expedited review if your situation warrants it. There is no penalty for requesting it and being denied expedited status — you simply proceed on the standard track.
Tips for Success at Every Level
- Get everything in writing: Every denial, every response, every conversation should be documented in writing.
- Cite medical necessity specifically: Your appeal must explain not just that you need the service but why this specific service is the medically appropriate choice for your specific condition.
- Reference Original Medicare standards: MA plans must cover at least what Original Medicare covers. NCDs and LCDs are your allies.
- Invoke Jimmo v. Sebelius when appropriate: If maintenance therapy or a lack-of-improvement argument is at issue, cite this case.
- Get your physician actively involved: Doctor support is one of the strongest predictors of appeal success at every level.
- Track all deadlines: Missing a deadline can forfeit your right to appeal at that level. Calendar every filing deadline the day you receive a decision.
- File a CMS complaint alongside your appeal: Reporting plan misconduct (late decisions, improper criteria) to CMS and your state SHIP adds regulatory pressure while your appeal proceeds.
