How to Fight a Medicare Denial and Win (2026)
Last checked: April 25, 2026
If Medicare, a Medicare Advantage plan, or a Medicare drug plan denied care, do not start with a long emotional letter. Start with the denial notice, the deadline, and the doctor’s written medical reason.
You can appeal many Medicare denials. But no article can promise you will win. The best goal is to file on time, use the right appeal path, and give Medicare or the plan the medical facts it needs to review the denial.
Bottom line
A Medicare denial is not always final. The simplest first step is this: read the denial notice, mark the deadline, call the provider’s billing office or plan, and ask the doctor for a short medical necessity letter.
If you are not sure what the notice means, contact your local State Health Insurance Assistance Program, also called SHIP. SHIP gives free Medicare counseling and can help you understand appeal rights, plan notices, and next steps.
What to do first today
- Find the denial notice. Do not rely on memory. The notice tells you who denied the claim, what was denied, where to send the appeal, and the deadline.
- Write the deadline on paper. Medicare appeal deadlines vary by the type of denial. The date on the notice controls.
- Call the doctor, facility, supplier, or pharmacy. Ask whether the claim was denied because of missing records, wrong coding, lack of prior authorization, or a medical necessity issue.
- Ask for written medical support. A short doctor letter is often more useful than a long family letter.
- Call SHIP for free help. Use the SHIP locator to find your state program.
If the denial involves a hospital discharge or Medicare-covered services ending soon, do not wait. Fast appeal deadlines can be very short.
⚠️ If care is ending soon, use the fast appeal route
If a hospital says your loved one must leave, or a skilled nursing facility, home health agency, hospice, or rehab provider says Medicare coverage is ending, read the notice right away.
Medicare’s fast appeal rules use different deadlines. In a hospital, follow the Important Message from Medicare by the deadline on the notice. In many non-hospital settings, the Notice of Medicare Non-Coverage tells you to contact the BFCC-QIO no later than noon the day before the termination date.
The BFCC-QIO contractor depends on where you live. Medicare currently lists Commence Health and Acentra Health as BFCC-QIO routes by region. Check your notice first because it should show the correct contact.
For more detail on discharge rights, see our guide to fighting a hospital discharge that feels too soon.
First, identify the notice in your hand
The appeal path depends on who denied the service. Original Medicare, Medicare Advantage, and Part D drug plans use different words and different forms.
If the notice is confusing, call the number on the notice and ask, “What kind of appeal is this, what is the deadline, and where do I send it?” Then call SHIP and ask them to read it with you.
| Notice or problem | What it usually means | What to do next |
|---|---|---|
| Medicare Summary Notice, or MSN | Original Medicare Part A or Part B denied or partly denied a claim. | Use the deadline and address on the MSN. Medicare explains the MSN on its Medicare Summary Notice page. |
| Medicare Advantage denial notice | Your Medicare Advantage plan denied a service, prior authorization, payment, or continued care. | Follow the plan notice and plan appeal instructions. Medicare explains appeals in Medicare health plans. |
| Part D drug denial or exception denial | Your drug plan denied a medication, tier exception, formulary exception, or reimbursement. | Ask the prescriber for a supporting statement. Medicare explains appeals in a Medicare drug plan. |
| Important Message from Medicare | A hospital discharge appeal may be available. | Follow the notice immediately. Medicare’s fast appeal page explains the BFCC-QIO route. |
| Notice of Medicare Non-Coverage | Medicare-covered services may be ending in skilled nursing, home health, hospice, or rehab. | Contact the BFCC-QIO by the deadline on the notice. Ask the provider for records sent to the reviewer. |
| Advance Beneficiary Notice, or ABN | A provider thinks Original Medicare may not pay for an item or service. | Read the choices before signing. CMS keeps current Medicare notice forms on its Beneficiary Notices Initiative page. |
Use the right Medicare appeal path
If your loved one has Original Medicare
Original Medicare means they use Medicare Part A and Part B directly, not a Medicare Advantage plan. The usual first appeal is called a redetermination.
Start with the MSN. Medicare’s page on appeals in Original Medicare says to file by the date shown on the MSN. Medicare also lists official appeals forms, including the Redetermination Request form, Reconsideration Request form, OMHA hearing form, and Appointment of Representative form.
For many Original Medicare claim denials, a provider billing office can tell you whether the problem was a missing record or coding issue. Sometimes the provider can resubmit a corrected claim. If the denial is about medical necessity, you will likely need a doctor letter and records.
If your loved one has Medicare Advantage
Medicare Advantage plans are private plans approved by Medicare. They must give written instructions on how to appeal a denial.
For Medicare Advantage, the first appeal is usually called a reconsideration from the plan. Medicare’s current page says you, your representative, or the doctor or provider generally must file within 65 days from the date on the initial denial notice. Still, always follow the notice because plan notices and situations vary.
For a prior authorization denial, call the plan and ask for the exact denial reason, the medical policy used, the fax number for appeals, and whether a fast appeal is available. If waiting could seriously harm your loved one’s health, ask the doctor to request an expedited appeal.
If the denial is for a Part D drug
Part D drug denials have their own path. The first request may be a coverage determination or exception. If that is denied, the first appeal is usually a redetermination by the drug plan.
Medicare’s drug plan appeal page says the prescriber’s statement matters when asking for an exception. Ask the prescriber to explain why the denied drug is medically needed, why covered alternatives are not right, or why a lower-cost step therapy drug is unsafe or ineffective for this person.
If the problem is hospital discharge or care ending
Fast appeals are different from ordinary claim appeals. The notice may involve the Beneficiary and Family Centered Care Quality Improvement Organization, often called the BFCC-QIO.
Use the phone number on the notice. You can also call 1-800-MEDICARE at 1-800-633-4227. TTY users can call 1-877-486-2048.
The five Medicare appeal levels
Medicare has five appeal levels. Most caregivers will never use all five. But it helps to know that a first denial is only the first decision.
The table below is a plain-English guide. Do not use it as a substitute for the notice. The notice controls the deadline, address, and exact next step.
| Level | What it is | Deadline to verify | Where to check |
|---|---|---|---|
| Level 1 | Redetermination for Original Medicare, or reconsideration for Medicare Advantage, or redetermination for Part D. | Original Medicare: file by the date on the MSN. Medicare Advantage and Part D: Medicare currently says 65 days from the initial denial notice. | Medicare filing an appeal |
| Level 2 | Independent review. For Original Medicare, this is reconsideration by a Qualified Independent Contractor, or QIC. | For Original Medicare, Medicare says you have 180 days after you get the Level 1 decision to ask for Level 2. | CMS second level appeal information |
| Level 3 | Administrative Law Judge, or ALJ, hearing or review through the Office of Medicare Hearings and Appeals, called OMHA. | For Original Medicare, the request is generally due within 60 days after the Level 2 decision. A minimum amount in controversy applies. Medicare lists $200 for 2026. | HHS Office of Medicare Hearings and Appeals |
| Level 4 | Medicare Appeals Council review. | Medicare says you generally have 60 days after the OMHA decision to request Council review. | CMS fourth level appeal information |
| Level 5 | Federal district court. | Medicare lists a 2026 minimum amount of $1,960 for federal district court review. This is the point where legal advice may be important. | Medicare Original Medicare appeal levels |
If the amount is small, the first or second level may be the practical limit. If the denial affects long-term care, therapy, home health, equipment, or a high-cost drug, it may be worth getting help early.
What to include in the appeal packet
The appeal packet should make the reviewer’s job easy. Put the strongest facts first. Keep a copy of everything.
📄 Documents to gather
- The denial notice, MSN, plan letter, or drug denial letter.
- The Medicare card or plan card.
- The dates of service, provider name, claim number, and item or service denied.
- Doctor notes, therapy notes, hospital records, home health records, or equipment orders.
- A signed doctor or prescriber letter explaining medical necessity.
- Any plan prior authorization request, denial reason, or medical policy cited by the plan.
- Proof of representation if you are filing for someone else, such as Medicare’s Appointment of Representative form when needed.
- A one-page caregiver timeline showing what happened and why care is still needed.
| Appeal packet item | Why it helps | Caregiver tip |
|---|---|---|
| Short cover letter | Explains exactly what you are appealing. | Use dates, claim numbers, and the denied service. Do not make the reviewer hunt for the issue. |
| Doctor letter | Shows medical necessity in the provider’s words. | Ask the doctor to connect the service to diagnosis, safety risks, function, and Medicare rules when possible. |
| Medical records | Back up the doctor letter with facts. | Include the most relevant pages. Do not send hundreds of pages without a cover note. |
| Plan denial policy or rule | Shows what standard the plan used. | Ask the Medicare Advantage plan for the policy or criteria used to deny the request. |
| Proof of mailing or fax | Protects you if the plan or contractor says it did not receive the appeal. | Use certified mail, fax confirmation, portal confirmation, or a dated upload receipt. |
What a doctor letter should say
A useful letter is not just “please approve.” It should explain why the item, service, therapy, home health, skilled nursing, equipment, or drug is medically needed for this person.
Ask the doctor or prescriber to include:
- The diagnosis and current health problem.
- The denied service, drug, equipment, or level of care.
- Why it is reasonable and necessary.
- What could happen without it, such as falls, infection, hospitalization, loss of function, pain, or unsafe care at home.
- Why a cheaper, easier, or non-skilled option is not enough.
- For drugs, why formulary alternatives, step therapy, or dose limits are not appropriate.
- For therapy or skilled care, whether the goal is improvement, maintenance, or slowing decline.
When “not improving” is the wrong reason
Caregivers often hear, “Medicare will not cover therapy because your parent is not improving.” That can be wrong.
The Jimmo settlement clarified that Medicare coverage for skilled nursing facility care, home health, and outpatient therapy cannot be denied just because the person is not expected to improve. The key question is whether skilled care is needed to maintain the person’s condition or prevent or slow decline, and whether all other Medicare coverage rules are met.
CMS explains this in its Jimmo v. Sebelius fact sheet. The Center for Medicare Advocacy also has a practical Jimmo and improvement standard resource.
This does not mean Medicare covers every long-term care need. Medicare still does not cover custodial care alone. For a broader explanation of what Medicare does and does not cover, see our plain-English guide to what Medicare actually covers.
Caregiver wording to use
Instead of saying, “She is not getting better but she still needs help,” say: “Please review whether skilled care is medically necessary to maintain her current function or prevent or slow further decline. Please do not deny only because she is not expected to improve.”
Phone scripts you can use
☎️ Call SHIP
“Hi, my parent received a Medicare denial notice. I am trying to understand the deadline and the correct appeal path. Can someone help me read the notice? The denial is for [service, equipment, drug, or care setting]. The notice date is [date], and the deadline says [date]. What should I do first?”
☎️ Call the doctor’s office
“Hi, Medicare or the plan denied coverage for [service or item]. I need help with an appeal. Can the doctor write a medical necessity letter that explains the diagnosis, why this care is needed, what could happen without it, and why the denial reason is not correct?”
☎️ Call the Medicare Advantage plan
“I am calling about a denial for [service]. Please tell me the appeal deadline, the fax or portal address, the case number, and the exact medical policy or rule used to deny it. If waiting could harm the patient, how does the doctor request an expedited appeal?”
☎️ Call the provider billing office
“I received a denial for claim [claim number] on [date]. Was this denied because of missing documentation, coding, prior authorization, or medical necessity? Can your office correct and resubmit it, or do we need to file an appeal?”
Common mistakes that hurt Medicare appeals
- Missing the deadline. The deadline on the notice matters. Put it on a calendar and aim to file early.
- Appealing without doctor support. A caregiver letter helps explain daily life, but a doctor or prescriber letter usually carries more medical weight.
- Assuming improvement is always required. For skilled care, maintenance or slowing decline may matter under Jimmo when other coverage rules are met.
- Sending only emotional facts. It is okay to explain hardship, but the appeal needs medical facts, dates, records, and the denied item or service.
- Not asking for the denial policy. In Medicare Advantage cases, ask the plan what rule, guideline, or medical policy it used.
- Ignoring Part D exception rules. A drug appeal may need a prescriber statement explaining why alternatives do not work.
- Waiting to ask for help. SHIP, the provider billing office, the doctor’s office, and 1-800-MEDICARE can help you understand the route.
- Not keeping proof. Keep fax receipts, upload confirmations, certified mail receipts, and copies of every page you send.
What varies by plan, state, and setting
Medicare is federal, but the practical route can still vary.
- Medicare Advantage plans vary. Each plan has its own member services number, portal, fax number, prior authorization process, and network rules.
- Part D plans vary. Formularies, step therapy rules, quantity limits, and exception forms differ by plan.
- SHIP is local. Your state SHIP may be run by an aging agency, insurance department, nonprofit partner, or local counseling network.
- BFCC-QIO contact varies by state or region. Use the number on the notice, or confirm through Medicare’s fast appeal information.
- Providers vary in how much they help. Some billing offices are experienced with appeals. Others may only give records and leave the appeal to the family.
- Hospital and facility notices vary by setting. A hospital discharge appeal is not the same as an ordinary denied claim for a past service.
What to do next
- Make a denial folder today. Put the notice, records, plan card, doctor contacts, and appeal deadline in one place.
- Call SHIP. Ask them to help you confirm the appeal type and deadline.
- Call the provider or plan. Ask exactly why the claim or service was denied.
- Ask the doctor for a medical necessity letter. Give the office the denial reason and deadline.
- File before the deadline. Keep proof that the appeal was received.
- If denied again, read the next decision letter. It should tell you how to move to the next level.
If the case reaches an ALJ hearing, a large dollar amount, a nursing facility stay, or a serious medical risk, consider asking SHIP, a legal aid office, an elder law attorney, or a Medicare advocate for help.

FAQ
How long do I have to appeal an Original Medicare denial?
The deadline is printed on the Medicare Summary Notice. Do not guess. Medicare says to file by the date shown on the MSN. If you miss the deadline, you may still ask for review if you can show good cause, but you should not count on that.
Can a caregiver file the appeal for a parent?
Sometimes, but you may need proof that you are allowed to act for them. Medicare has an Appointment of Representative form. A doctor, provider, or prescriber may also be able to request certain lower-level appeals, especially for Medicare Advantage or Part D, but the notice should be checked.
What if Medicare Advantage denied prior authorization?
Call the plan and ask for the denial reason, the appeal deadline, and the medical policy used. Medicare currently says a Medicare Advantage appeal is generally due within 65 days from the initial denial notice. If waiting could harm your loved one, ask the doctor about an expedited appeal.
Does Jimmo mean Medicare must cover therapy forever?
No. Jimmo does not remove Medicare’s other coverage rules. It means skilled care should not be denied only because the person is not improving. The appeal still needs to show that skilled care is reasonable and necessary.
Should I pay the bill before appealing?
Ask the provider billing office what happens during the appeal. In some cases, you may be able to ask them to hold billing or collections while the appeal is pending. Get the answer in writing when possible. Do not ignore bills or collection letters.
Who can help me for free?
Start with SHIP for free Medicare counseling. You can also call 1-800-MEDICARE, ask the provider billing office for help, and ask the doctor’s office for medical records and a medical necessity letter.
Resumen en español
Si Medicare o un plan Medicare Advantage niega cuidado, equipo, terapia o medicina, no significa que la decisión sea final. Lea la carta de negación, marque la fecha límite y llame al consultorio médico para pedir una carta de necesidad médica.
También puede llamar a SHIP, un programa gratuito de ayuda con Medicare, para que le ayuden a entender la carta y los próximos pasos. No espere si el hospital o un centro dice que el cuidado va a terminar pronto.
