A Medicare Advantage denial is not the end. Federal law gives you five levels of appeal—and statistics show that appealing works. When the HHS OIG audited MA denials, about 75% of wrongfully denied cases were overturned on appeal. Most people never appeal. You should.

The 5-Level Medicare Advantage Appeals Process
| Level | Where to Appeal | Deadline | Decision Timeline |
|---|---|---|---|
| 1 — Redetermination | Your MA plan | 60 days from denial | 60 days (30 for prior auth) |
| 2 — QIC Review | Qualified Independent Contractor | 60 days from Level 1 decision | 60 days standard / 72 hrs expedited |
| 3 — ALJ Hearing | Administrative Law Judge (OMHA) | 60 days from Level 2 decision | 90-day target |
| 4 — Appeals Council | Medicare Appeals Council | 60 days from ALJ decision | No set deadline |
| 5 — Federal Court | US District Court | 60 days from Level 4 decision | Varies |
💡 60 days is your recurring deadline. At every level, you have 60 days from the prior decision to escalate. Missing this deadline generally forfeits your right to appeal at that level. Set calendar reminders immediately when you receive each decision.
Step-by-Step Appeal Guide
- Get everything in writing first Request your full Explanation of Benefits (EOB) and the formal written denial notice. The notice must state the exact reason for denial and the coverage criteria used. Without this, you cannot build an effective appeal.
- Ask your doctor for a Letter of Medical Necessity This is the single most powerful piece of evidence in a claim appeal. The letter should include your diagnosis (ICD-10 codes), the specific treatment requested, why it is medically necessary for your condition, and why alternatives are inadequate or have already failed.
- File a Level 1 Redetermination with your plan Submit in writing within 60 days. Include your EOB, the denial notice, your doctor’s Letter of Medical Necessity, and a cover letter clearly stating what you’re appealing and why. Request acknowledgment of receipt.
- For urgent care: request expedited review If the standard timeline would seriously jeopardize your health, you can request an expedited appeal—your plan must respond within 72 hours. Your doctor must support the urgency in writing.
- Escalate to QIC if denied at Level 1 If the plan upholds the denial, escalate to the Qualified Independent Contractor. Submit within 60 days, include all prior documentation, and add any new clinical evidence your doctor can provide.
- Request an ALJ hearing if still denied If the QIC upholds the denial and the amount at issue is at least $200, request an ALJ hearing within 60 days. This is a formal hearing, but you don’t need a lawyer—though a patient advocate or SHIP counselor can help.
Tips That Significantly Improve Appeal Success
- Reference Medicare’s coverage rules directly. Look up Medicare’s National Coverage Determinations (NCDs) and Local Coverage Determinations (LCDs) for your specific treatment. If your care meets these criteria, cite them in your appeal letter.
- Get peer-reviewed clinical support. If the plan claims your treatment is “not medically necessary” or “experimental,” ask your doctor to provide clinical literature supporting the treatment for your specific condition.
- Use form CMS-20027 for organization-level appeals or submit in your own words—there is no required format at Level 1.
- File before the deadline, then supplement. Submit your appeal on time even if you’re still gathering evidence. You can add supporting documents afterward as long as the appeal is already open.
- Get free help from your SHIP counselor. State Health Insurance Assistance Programs help with Medicare appeals at no cost. Find your state’s counselor at shiphelp.org.
⚠️ Don’t accept “no” at Level 1. The plan’s own reviewers conduct Level 1 redeterminations. This is the least independent review of your claim. Statistics show the highest overturn rates come at Levels 2 and 3, where independent reviewers evaluate whether Medicare coverage criteria were actually met.
Frequently Asked Questions
What are the grounds for appealing a Medicare Advantage denial?
Any time your plan denies coverage for a service you believe meets Medicare coverage criteria, you can appeal. Common grounds: the service is medically necessary per your doctor, the plan used incorrect clinical criteria, or the service is covered under Medicare’s national coverage rules.
How long do I have to appeal a Medicare Advantage denial?
60 days from each denial decision to escalate to the next level. Set reminders — missing deadlines generally forfeits your appeal rights at that level.
What is an expedited appeal in Medicare Advantage?
For urgent care situations, you can request expedited review—the plan must respond within 72 hours. Your treating physician must confirm in writing that the standard timeline would jeopardize your health.
Do I need a lawyer to appeal a Medicare Advantage claim?
No. Most appeals succeed without a lawyer. A free SHIP counselor, a Letter of Medical Necessity from your doctor, and clear reference to Medicare coverage criteria are usually sufficient through Levels 1–3.
What is the success rate for Medicare Advantage claim appeals?
Per the HHS OIG audit, approximately 75% of wrongfully denied prior authorization and claim appeals were overturned when patients escalated. The key is actually appealing—most patients don’t.
