Bottom line: A Medicare Advantage denial is not always the final answer. Most seniors and caregivers should read the notice the same day, mark the deadline, ask the doctor for a strong letter, and file a level 1 appeal called a reconsideration. Current health plan appeals rules say the first appeal is usually due within 65 days of the denial notice. If waiting could harm health or recovery, ask for a fast appeal right away.
Emergency help now
Act fast if care is being delayed, stopped, or reduced. Do not wait for the next regular doctor visit if the denial affects surgery, rehab, a skilled nursing facility, home health, a Part B drug, oxygen, a wheelchair, or safe discharge from the hospital.
- Find the date on the notice: The date on the denial notice usually starts the appeal clock.
- Call the plan and the doctor today: Ask both sides what was denied, why it was denied, and what records are missing.
- Ask for fast review if health is at risk: Under CMS reconsideration rules, a doctor’s request for an expedited appeal must be treated as expedited.
- Use the right fast path: If a hospital, skilled nursing facility, home health agency, hospice, or outpatient rehab service is ending too soon, the fast appeal process on the notice may be the right path.
- Keep proof: Save fax confirmations, portal messages, mail receipts, names, dates, and reference numbers.
Quick help
- First appeal deadline: Usually 65 days from the date on the denial notice.
- Standard appeal timing: Plans usually have 30 days for a pre-service appeal, 60 days for a payment appeal, and 7 days for a standard Part B drug appeal.
- Fast appeal timing: Plans usually have 72 hours for an expedited pre-service or Part B drug appeal.
- Outside review: If the plan says no again, the case is usually sent to an Independent Review Entity, or IRE.
- Caregiver help: A family member can help more formally with the CMS-1696 form or a similar written appointment.
| Problem | Start here | Reality check |
|---|---|---|
| Care was denied before it happened | File a level 1 reconsideration and ask the doctor to send records. | A corrected prior authorization may also be needed. |
| Care is ending too soon | Use the fast appeal instructions on the notice. | Deadlines can be very short. |
| A bill came after care | File a payment appeal and ask the provider to pause collections. | Payment appeals often take longer. |
| A pharmacy drug was denied | Check if this is a Part D drug appeal. | Pharmacy drugs may use a different path. |
| A caregiver is handling it | Send representative paperwork early. | The plan may not speak freely without it. |

What this means
A Medicare Advantage plan is run by a private insurance company approved by Medicare. It must cover medically necessary Medicare-covered care, but it can use plan rules, networks, and prior authorization for many services.
A coverage decision in a Medicare Advantage plan is called an organization determination. If the plan denies the request, the first appeal is called a reconsideration. The current organization determination page explains this plan decision path.
Do not assume the denial is correct. A 2026 KFF analysis found that Medicare Advantage insurers made 52.8 million prior authorization determinations in 2024. About 4.1 million were denied in full or in part. Only 11.5% of denials were appealed, but 80.7% of appealed denials were overturned.
This does not mean every appeal will win. It means many denials are worth checking. The strongest appeals answer the exact denial reason and include medical records, not just a general note that says the doctor wants the service.
This guide is for Medicare Advantage medical denials, including prior authorization denials, payment denials, medical equipment denials, skilled nursing facility issues, home health denials, and Part B drug denials. A pharmacy drug denial may follow a separate Medicare drug appeals path. If home health is the main issue, also see our home health denials guide.
Read the denial notice
Most Medicare Advantage medical denials use a Notice of Denial of Medical Coverage or Payment. CMS also calls it an Integrated Denial Notice. The denial notice page says plans must use this notice when they deny coverage or payment, or when they reduce or stop a previously approved course of treatment.
Mark these items on the notice before you call anyone:
- What was denied: Write the exact service, item, drug, number of visits, number of days, or setting.
- Why it was denied: Look for words like “not medically necessary,” “not covered,” “out of network,” “wrong setting,” or “missing information.”
- The notice date: This usually starts the 65-day level 1 appeal deadline.
- The appeal address: Use the fax number, mailing address, portal, or phone number listed on the notice.
- The case number: Put this number on every page you send.
- What could change the answer: The notice may say what records or facts could support approval.
- Medicaid rights: If the person has both Medicare and Medicaid, there may be extra state appeal rights.
Red flag: If the notice is vague or missing pages, call the plan and ask for the full denial notice and the case file. The official Medicare appeals booklet says members can ask for the file that has the medical and other information used in the case.
If the issue is a form signed before care, read our Medicare ABN guide. An Advance Beneficiary Notice is usually an Original Medicare issue, but it can still help families understand billing warnings before care happens.
Standard and fast appeals side by side
The first decision is speed. A standard appeal is for a case that can safely wait. A fast appeal is for a case where waiting could seriously harm the person’s health, recovery, or ability to regain function.
| Question | Standard appeal | Fast appeal |
|---|---|---|
| When to use it | The care decision can safely wait. | Delay could seriously harm health or recovery. |
| Who can ask | The member, representative, doctor, or provider. | The member, representative, doctor, or provider. |
| How to ask | Usually in writing unless the plan accepts phone requests. | By phone or in writing. Follow with records. |
| Plan decision time | 30 days for pre-service, 60 days for payment, or 7 days for Part B drugs. | Usually 72 hours for pre-service and Part B drug appeals. |
| Doctor support | Helpful and often important. | Very important. Ask the doctor to state why delay is unsafe. |
Important: If care is ending too soon in a hospital, skilled nursing facility, home health agency, hospice, or comprehensive outpatient rehab facility, use the notice for that service. The CMS BFCC-QIO page explains the review path for many service termination cases. Our fast appeal guide explains those short deadlines in more detail.
How to start without wasting time
Write one case sheet
Use one page. Put the member’s name, Medicare number, plan member number, case number, notice date, service denied, appeal deadline, plan phone number, fax number, and doctor contact. Keep this page on top of the file.
Call the doctor’s authorization team
Ask for the office that handles prior authorization, referrals, utilization management, or discharge planning. Ask whether the denial was caused by missing records, a wrong code, a wrong setting, a network issue, or a medical need dispute.
File on time, even if records are still coming
Do not miss the deadline while waiting for perfect paperwork. File the appeal and say that more records will follow. Then send the added pages as soon as they are ready.
Ask about a corrected request too
Some denials happen because the wrong code, setting, or document was sent. The provider may be able to submit a corrected prior authorization while the appeal is also pending. This is not a replacement for an appeal deadline. It is a second path that may fix a simple problem.
Know what changed in 2026
CMS prior authorization rules now require many impacted payers, including Medicare Advantage organizations, to send urgent prior authorization decisions within 72 hours and standard decisions within 7 calendar days. The official public reporting FAQ also says payers had to post certain 2025 prior authorization metrics by March 31, 2026. These rules help with initial prior authorization timing and transparency. They do not erase the appeal steps after a denial.
Document checklist
Send a clean packet. Put the denial notice first. Then add the appeal letter, doctor letter, and records. Do not send loose pages without the member’s name and case number.
- ☐ Full denial notice
- ☐ Member’s Medicare number
- ☐ Plan member number
- ☐ Appeal letter
- ☐ Doctor or specialist letter
- ☐ Office notes
- ☐ Hospital discharge papers
- ☐ Therapy notes or progress notes
- ☐ Test results or imaging reports
- ☐ Medication history
- ☐ Records of what was tried before
- ☐ Representative form, if needed
- ☐ Fax, mail, or portal proof
If cost is part of the problem, read our medical debt rights guide before ignoring bills or collection notices.
What to ask the doctor to write
A one-line note is often too weak. Ask for a focused letter that answers the denial reason. The letter should explain why this patient needs this exact care now.
- Name the service: Include the test, surgery, rehab days, home health visits, medical equipment, or Part B drug.
- State the diagnosis: Add the condition, symptoms, and how daily life is affected.
- Explain why now: Say why delay could worsen pain, function, falls, infection risk, recovery, or safe discharge.
- Answer the denial: If the plan says “not medically necessary,” the letter should answer that phrase directly.
- Explain alternatives: Say what was tried, why it failed, or why a lower level of care is unsafe.
- Attach proof: Add recent notes, therapy logs, test results, imaging, wound notes, or medication history.
For drug step therapy problems, see our step therapy help guide. It explains how to document why the plan’s preferred drug may not work for the person.
Deadlines that matter most
Medicare Advantage appeals can have five levels. Most people focus first on levels 1 and 2. Higher levels can take more time and may require a minimum dollar amount.
| Level | Who reviews it | How it starts | Main timing |
|---|---|---|---|
| Level 1 | The plan | You ask for reconsideration. | Usually file within 65 days. Plan timing is usually 30 days, 60 days, 7 days, or 72 hours based on case type. |
| Level 2 | Independent Review Entity | Starts automatically if the plan upholds the denial. | Usually uses the same decision timeframes as level 1. |
| Level 3 | Office of Medicare Hearings and Appeals | You ask after a level 2 denial. | Usually request within 60 days. The 2026 ALJ amount is $200 under the ALJ amount notice. |
| Level 4 | Medicare Appeals Council | You ask after level 3. | Usually request within 60 days. |
| Level 5 | Federal District Court | You ask after level 4. | The 2026 court amount is $1,960. |
If the plan misses a level 1 deadline or issues an unfavorable decision, the case should be sent for outside review. If your case is already at a higher level, follow the instructions in the newest decision letter, not an old address found online.
Best next move by denial type
Use the quickest path for the real problem. Do not use a slow standard appeal when the notice gives a faster service-ending appeal path.
| What happened | Best next move | Why it helps |
|---|---|---|
| MRI, CT, surgery, or procedure denied before the appointment | Ask the doctor to resubmit with better records and file level 1. | This covers both missing-record and appeal paths. |
| Skilled nursing, rehab, home health, hospice, or hospital care ending | Use the fast appeal notice and call the BFCC-QIO. | This can protect coverage faster than a routine appeal. |
| Plan will not pay after care happened | File a payment appeal and ask billing to pause collections. | Billing can grow while the appeal is pending. |
| Part B drug denied | Ask the doctor if fast review is needed. | Part B drug appeal timing can be faster than other medical appeals. |
| Member changed plans during treatment | Ask about the 90-day rule for active treatment. | Some active care may be protected during a plan change. |
If the denial makes the plan a poor fit, the person may want to review plan choices during a valid enrollment period. Our Medigap trial right guide explains one limited protection for some people who try Medicare Advantage and want to return to Original Medicare with Medigap.
What to do while waiting
- Check messages daily: Plans may ask for more records quickly.
- Keep the doctor involved: Ask whether more notes, tests, or corrected codes are needed.
- Ask about safe short-term care: Do not stop care without asking the clinician what is safe.
- Do not ignore bills: Tell the provider in writing that the denial is under appeal.
- Keep a call log: Write the date, time, name, phone number, and reference number for every call.
- Recheck urgency: A standard case can become urgent if health gets worse.
If the member has both Medicare and Medicaid, read our dual eligible guide. Medicaid rights and plan rules can affect who pays and which notices arrive.
Scripts you can use
Call the Medicare Advantage plan
“I am calling about denial case number [number]. Please tell me the exact denial reason, the appeal deadline, where to fax the appeal, and whether this can be handled as an expedited appeal. I also want to know what records would support approval.”
Call the doctor’s office
“The plan denied [service]. Can your authorization team review the denial notice today? Please send a letter that answers the denial reason and explains why delay could harm [name]. Please attach records that support the request.”
Call the billing office
“This Medicare Advantage denial is under appeal. Please place the account on hold while the appeal is pending. I can send proof of the appeal. Please also send an itemized bill and the denial reason in writing.”
Call SHIP or Medicare
“I need help with a Medicare Advantage denial. The notice date is [date], and the service is [service]. Can you help me understand the deadline and what appeal path fits this case?”

Common mistakes to avoid
- Waiting too long: File before the deadline, even if more records will follow.
- Using the wrong appeal path: Service termination cases may have a special fast appeal.
- Sending a vague appeal: “My doctor says I need it” is weaker than records that answer the denial reason.
- Not asking for fast review: If delay could harm health, say so clearly.
- Assuming the doctor appealed: Ask for the fax confirmation or appeal reference number.
- Ignoring collection letters: Ask billing to pause collections in writing.
- Skipping representative forms: A caregiver may need written permission to act for the member.
What to do if denied, delayed, or overwhelmed
If the plan denies level 1
Read the new decision letter. If the plan upholds the denial, the case is usually sent to the Independent Review Entity. Add any stronger doctor letter or missing record as soon as the instructions allow.
If the plan never answers
Call the plan and ask whether the case was forwarded for outside review. Write down the answer. Then call Medicare or SHIP for help checking the next step.
If the plan refuses fast review
Ask how to file an expedited grievance about the refusal. Also ask the doctor to send a stronger urgent statement the same day. The statement should explain the health risk of waiting.
If the case is too hard to handle alone
Ask a trusted helper to organize papers and calls. If the member wants that person to speak for them, use representative paperwork. For possible help paying Medicare costs, see our Medicare Savings Programs guide.

Frequently asked questions
How long does a senior have to appeal a Medicare Advantage denial?
The first appeal is usually due within 65 days from the date on the denial notice. If the deadline was missed, file anyway and explain why it is late.
Is a Medicare Advantage denial final?
No. The first appeal goes back to the plan as a reconsideration. If the plan upholds the denial, the case usually goes to an outside reviewer.
Who can ask for a fast appeal?
The member, representative, doctor, or provider can ask. If the doctor asks for the fast appeal and says waiting could seriously harm the person, the plan must treat it as expedited.
What if home health or rehab is ending too soon?
Use the fast appeal instructions on the notice. These cases can have very short deadlines, so call the number on the notice right away.
What should a doctor letter say?
It should name the service, explain the diagnosis, answer the denial reason, show why the care is needed now, and attach records that support the request.
What if the plan never answers?
Call the plan and ask whether the case has moved to outside review. Then call Medicare or SHIP if the answer is unclear or the deadline has passed.
Can a caregiver file the appeal?
Yes, but the plan may need written permission. Use the representative form or a similar written statement if the caregiver will act for the member.
Can the senior get care while the appeal is pending?
Sometimes, but it can be risky. Some service-ending fast appeals can protect coverage while the case is reviewed. Other care may create a bill if the appeal fails.
