Medicare's 5 Levels of Appeal: Complete Guide
Medicare has 5 levels of appeal, each with its own deadline and decision threshold. Learn how Redetermination, QIC, ALJ, Appeals Council, and federal court work.
Medicare operates a five-level appeals process that applies when Medicare — or a Medicare Advantage plan — denies a claim, reduces a benefit, or terminates a service. Each level has specific filing deadlines, decision timelines, and monetary thresholds. Understanding the full pathway is essential because the stakes get higher and the procedures get more formal as you ascend the ladder.
This guide applies primarily to Medicare Parts A and B (Original Medicare). Medicare Advantage (Part C) and Part D drug appeals have related but distinct processes — noted where relevant.
When to Appeal: The Initial Denial
Before reaching any appeal level, you receive an initial determination — a formal written decision from Medicare or your plan. For Medicare, this appears on your Medicare Summary Notice (MSN) or Explanation of Medicare Benefits (EOMB). The denial will identify the reason, the amount at issue, and your appeal rights.
Critical: The appeal clock starts from the date on this initial determination notice. Mark it immediately.
Level 1: Redetermination
Who decides: The same Medicare Administrative Contractor (MAC) that issued the original denial — but a different staff member reviews it.
Filing deadline: 120 days from the date you receive the initial determination (assumed to be received 5 days after the date on the notice).
How to file: Submit a written request to the MAC whose name and address appears on your MSN or EOMB. Include:
- Your Medicare ID number (red, white, and blue card)
- The date of service and service or item in dispute
- The reason you believe Medicare should pay
- Supporting documentation (physician letters, medical records)
Decision timeline: Medicare must issue a Redetermination decision within 60 days of receiving your request. If no decision within 60 days, you may escalate to Level 2.
Success rate: Redeterminations have relatively low reversal rates — the same MAC is reviewing its own denial. But submitting additional documentation at this stage strengthens your record for higher levels.
Level 2: Reconsideration by a Qualified Independent Contractor (QIC)
Who decides: An independent Qualified Independent Contractor (QIC) with no affiliation with the MAC that denied the claim. This is the first truly independent review.
Filing deadline: 180 days from the date of the Redetermination decision.
How to file: Submit your request to the QIC identified in your Redetermination notice. Include:
- All documentation previously submitted
- New evidence you want considered
- A detailed argument addressing the Redetermination's specific reasons for denial
Decision timeline: QIC must decide within 60 days. For expedited QIC review (pre-service or concurrent care): 72 hours.
Success rate: QIC reversals are more common than MAC redeterminations. An independent medical reviewer reads your case fresh. Submit your strongest clinical documentation here.
Level 3: Administrative Law Judge (ALJ) Hearing
Who decides: An Administrative Law Judge from HHS's Office of Medicare Hearings and Appeals (OMHA).
Filing deadline: 60 days from receipt of the QIC decision.
Monetary threshold: The amount in controversy must meet a minimum threshold to qualify for an ALJ hearing. For 2026, this threshold is approximately $200 (adjusted annually for inflation).

How to file: Submit a request for hearing to OMHA (omha.hhs.gov). You can request an in-person hearing, a telephone hearing, or a video teleconference. Importantly, you may now submit your hearing request online through the OMHA ePortal.
What makes ALJ hearings different:
- The ALJ is not a Medicare employee — they are an administrative judge who applies Medicare law independently
- You can submit new evidence that was not available at lower levels
- You can present witnesses, including your treating physician
- The ALJ can rule on legal questions, not just clinical ones
Decision timeline: OMHA aims to decide within 90 days but significant backlogs exist — some cases take 1-3 years.
Success rate: ALJ hearings historically have among the highest reversal rates in the Medicare system, particularly for complex medical necessity cases where treating physician testimony is compelling.
Level 4: Medicare Appeals Council
Who decides: The Departmental Appeals Board (DAB) within HHS. This is a paper review — no live hearing.
Filing deadline: 60 days from receipt of the ALJ decision.
How to file: Request a review by the Medicare Appeals Council through the DAB online portal at appeals.hhs.gov.
What the Council reviews: The Council can accept or deny review of the ALJ's decision. If it accepts, it reviews the entire record and may affirm, modify, or reverse the ALJ's ruling. It can also remand the case back to OMHA for further proceedings.
Decision timeline: No statutory deadline — the Council operates on a best-efforts basis. Cases can take 12-24+ months.
Level 5: Federal District Court
Who decides: A federal district court judge under the judicial review provisions of the Social Security Act, 42 U.S.C. § 405(g).
Filing deadline: 60 days from receipt of the Medicare Appeals Council decision.
Monetary threshold: The amount in controversy must be at least approximately $1,870 (2026 adjusted figure) to qualify for federal court review.
What this involves: A federal lawsuit requires legal representation in most cases. The court reviews the administrative record to determine whether Medicare's decision was supported by substantial evidence and whether it followed proper procedures.
Medicare Advantage (Part C) Appeals
Medicare Advantage plans have their own Level 1 process (plan-level appeal, decided in 14 days for standard / 72 hours for expedited), then escalate to an independent review entity (IRE), then to ALJ, Medicare Appeals Council, and federal court — the same five levels, but starting within the plan rather than with a MAC.
Medicare Part D (Drug) Appeals
Part D drug denials also follow a five-level process, beginning with a plan-level redetermination, then an Independent Review Entity (IRE) for Part D plans, then ALJ, Appeals Council, and federal court.
Key Tips for the Medicare Appeals Process
- Submit new evidence at every level — you are not limited to what was submitted before
- Get your physician involved — treating physician letters and testimony are consistently the most persuasive evidence
- Track your deadlines precisely — the 60-day window at Levels 3, 4, and 5 is strict
- Consider legal assistance for Levels 4 and 5 — an ERISA/Medicare attorney can significantly improve outcomes at these stages
- Request a stay of execution at Level 3 if the service is ongoing — an ALJ can sometimes order continuation of services during the hearing process
Medicare's appeal process is long, but it is specifically designed to be accessible. Hundreds of thousands of Medicare beneficiaries successfully navigate it each year.
