Medicare Advantage Appeal Deadlines: Every Timeframe You Need to Know
Missing a deadline can end your Medicare Advantage appeal before it starts. This guide covers every appeal timeline — from initial denial to federal court — so you never miss a date.
Medicare Advantage Appeal Deadlines: Every Timeframe You Need to Know
When your Medicare Advantage plan denies a claim, time is not on your side. Each level of the appeals process has a strict deadline, and missing it can mean losing your right to appeal at that level. For seniors managing health problems and busy lives, keeping track of these dates can be the difference between a successful appeal and a forfeited right.
This guide provides a complete reference for every deadline in the Medicare Advantage appeals process — both the deadlines you must meet to file, and the deadlines your plan must meet to respond.
Understanding Medicare Advantage Appeal Levels
Medicare Advantage plans must follow a five-level appeals process set by federal law. Here's a complete overview of the timelines:
Level 1: Organization Determination (Initial Decision)
This is not yet an appeal — it's the plan's first decision on your claim or Prior Authorization Denied: How to Appeal" class="auto-link">prior authorization request.
Your plan's deadline to decide:
- Standard: 14 calendar days for prior authorization requests; 30 calendar days for post-service claims
- Expedited (urgent): 72 hours
What triggers the right to appeal: A denial, partial approval, or adverse organization determination.
Your deadline to appeal to Level 2: 60 calendar days from the date of the denial notice.
Level 2: Plan Reconsideration (Internal Appeal)
Your plan reviews the denial again, usually with its own medical review staff.
Your deadline to file: 60 calendar days from the Level 1 denial date.
Your plan's deadline to respond:
- Standard: 30 calendar days for pre-service (prior auth) appeals; 60 calendar days for post-service (payment) appeals
- Expedited: 72 hours
What triggers expedited review: Your physician certifies in writing that applying the standard timeline would seriously jeopardize your life, health, or ability to regain maximum function.
If the plan upholds the denial: The case is automatically forwarded to an Independent Review Entity (IRE) — you do not need to file again.
Level 3: Independent Review Entity (IRE) Reconsideration
An independent organization contracted by CMS reviews your case. This review is completely separate from your plan.
Your deadline to file: If your plan does not automatically forward the case to the IRE, you have 60 days from your plan's Level 2 denial to request IRE review.
The IRE's deadline to decide:
- Standard: 30 days (for pre-service); 60 days (for post-service claims)
- Expedited: 72 hours
Important: For cases involving $100 or more in dispute, the IRE review is automatic upon plan uphold. For smaller amounts, you may need to request it.
Level 4: Administrative Law Judge (ALJ) Hearing
You request a hearing before an ALJ at the Office of Medicare Hearings and Appeals (OMHA).
Your deadline to file: 60 calendar days from the IRE's denial notice.
Minimum amount in controversy (2026): $180 (this threshold is adjusted annually).

Hearing timeline: ALJ hearings are typically scheduled within 90 days of the request, but actual timelines vary based on OMHA workload. You may request an expedited ALJ hearing in urgent medical circumstances.
What to expect: You may appear in person, by phone, or by video. You can bring a representative. The ALJ is a neutral hearing officer — not affiliated with Medicare or your plan — which is why this level often produces favorable outcomes.
Level 5: Medicare Appeals Council (MAC)
If you disagree with the ALJ's decision, you can appeal to the Medicare Appeals Council, which is part of the Department of Health and Human Services Departmental Appeals Board.
Your deadline to file: 60 calendar days from the ALJ's written decision.
Minimum amount in controversy: Same as ALJ level ($180 in 2026).
Timeline: MAC reviews are administrative — no live hearing is typically held. Timeline varies.
Level 6: Federal District Court
The final level of appeal, available if all administrative levels have been exhausted.
Your deadline to file: 60 calendar days from the MAC's decision.
Minimum amount in controversy (2026): $1,840 (adjusted annually).
Note: Federal court appeals require legal representation in most cases and involve significantly more time and expense. Most cases are resolved before this level.
Good Cause Extensions
If you miss a deadline due to circumstances beyond your control — serious illness, family emergency, natural disaster, or other compelling reasons — you can request a "good cause" extension. Submit your request in writing with a brief explanation and supporting documentation. Extensions are not guaranteed, but legitimate circumstances are considered.
Tips for Never Missing a Deadline
Act the day the denial arrives. Don't set the letter aside. Read it immediately, note the deadline (it must be stated in the letter), and calendar it.
Work backward from the deadline. If you have 60 days, plan to submit your appeal within 30–45 days to allow time for gathering documentation, physician letters, and review.
Use certified mail or the plan's portal. Keep proof of submission date. The postmark or upload timestamp is your deadline evidence.
When in doubt about the timeline, call. Contact your plan at the member services number on your insurance card and ask for your appeal deadline in writing.
Note the distinction: denial date vs. notice date. Some deadlines run from the date of the denial; others run from when you received notice. Read the letter carefully.
When Your Plan Misses Its Own Deadline
If your Medicare Advantage plan fails to respond to an appeal within the required timeframe, this is considered an automatic denial at that level — meaning your case automatically advances to the next level. If your plan is unresponsive, document your submission, note the deadline, and escalate to the IRE immediately. You can also file a complaint with CMS at Medicare.gov.
