Where do I start? With your notice
Every Medicare denial comes with a written notice that explains the decision, how to appeal and the deadline. Which notice you get depends on your coverage:
- Original Medicare: the Medicare Summary Notice (MSN), mailed to you or available in your Medicare.gov account. It shows which claims were denied and where to send an appeal.
- Medicare Advantage plan: a written denial notice from the plan, and the Explanation of Benefits for payment decisions.
- Part D or a Medicare plan with drug coverage: a notice from the plan. If the pharmacy can't fill a prescription, ask the pharmacist how to contact your plan for a coverage decision.
Keep copies of everything, and ask your doctor for a letter explaining why you need the service or drug. A doctor's support often makes the difference. You can name a family member or someone else to act for you with Medicare's Appointment of Representative form (CMS-1696); see helping a parent with Medicare.
What are the five levels in Original Medicare?
| Level | Who decides | Deadline to ask |
|---|---|---|
| 1. Redetermination | The Medicare Administrative Contractor that processed the claim | By the date on your MSN; decision generally within 60 days |
| 2. Reconsideration | A Qualified Independent Contractor (QIC) | 180 days after the level 1 decision; decision within 60 days |
| 3. Hearing | The Office of Medicare Hearings and Appeals (an Administrative Law Judge hearing or a review of the record) | 60 days after the level 2 decision |
| 4. Appeals Council review | The Medicare Appeals Council | 60 days after the level 3 decision |
| 5. Judicial review | Federal district court | 60 days after the Appeals Council decision |
Levels 3 and 5 apply only if the amount in dispute is at least a minimum that Medicare sets each year, and the level 5 minimum is much higher. You may be able to combine claims to reach it. Medicare.gov publishes the current amounts.
How do Medicare Advantage appeals work?
With a Medicare Advantage plan, the plan makes the first decisions, and the steps have different names:
- Organization determination. The plan decides whether it will cover a service or pay a claim, including prior authorization. If waiting could seriously harm your health, you or your doctor can ask for a fast decision.
- Reconsideration (level 1). If the plan says no, you, your representative or your doctor can appeal within 65 days of the date on the denial notice. The plan decides within 30 days for a service you haven't received, 60 days for a payment, 7 days for a Part B drug, or 72 hours for a fast appeal. It can take up to 14 more days in some cases, and must tell you in writing.
- Independent Review Entity (level 2). If the plan keeps its denial, it must send your case automatically to an independent reviewer. You don't have to file anything.
- Levels 3 to 5. Same as Original Medicare: a hearing, the Medicare Appeals Council, then federal court, with the same yearly minimum amounts.
Special needs plans must tell you in writing how to appeal. If you have both Medicare and SoonerCare, see dual special needs plans in Oklahoma.
How do Part D drug appeals work?
- Coverage determination. Ask your plan to cover a drug, including an exception (to cover a drug not on its list, waive a step-therapy or quantity rule, or lower your cost-sharing tier). Your prescriber's statement explaining the medical reason helps. If waiting could seriously jeopardize your life, health or ability to regain maximum function, ask for a fast decision.
- Redetermination (level 1). If the plan says no, ask for a redetermination within 65 days of the date on the denial notice. The plan decides within 7 days (14 days for a payment request), or 72 hours for a fast appeal.
- Independent Review Entity (level 2). Unlike Medicare Advantage medical appeals, you must ask for this review yourself, within 60 days of the plan's decision.
- Levels 3 to 5. A hearing, the Medicare Appeals Council and federal court, with yearly minimum amounts for levels 3 and 5.
Tip: If drug costs are the problem rather than a denial, Part D's yearly out-of-pocket cap is $2,100 in 2026, and you may qualify for Extra Help or a Medicare Savings Program. See Medicare Savings Programs in Oklahoma and our drug cost cap calculator.
What if my hospital stay or care is ending too soon?
When covered care is ending, a separate, faster process applies. In Oklahoma, these appeals go to Acentra Health, the Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO) for Oklahoma, at 1-888-315-0636 (TTY 711). The phone number is also printed on your notice.
Leaving the hospital
You should get the Important Message from Medicare within 2 days of admission and again before discharge. If you think you're being discharged too soon, call the BFCC-QIO no later than your planned discharge day. It decides within one day of getting the information it needs. If you ask on time, you can stay while it decides without paying for the extra days, other than usual deductibles or coinsurance.
Skilled nursing, home health, hospice
You should get a Notice of Medicare Non-Coverage at least 2 days before covered services end at a skilled nursing facility, from a home health agency or hospice, or at a comprehensive outpatient rehabilitation facility. To appeal, call the BFCC-QIO by noon of the day before the date on the notice.
If you miss these deadlines, you can still ask your plan for a fast reconsideration, but services are covered only if the decision goes your way. The BFCC-QIO also reviews complaints about the quality of care you got from a doctor, hospital or other provider under Medicare.
If your nearest hospital is a Rural Emergency Hospital that transferred you to a bigger city, the same discharge rights apply at the hospital that admitted you. See rural hospitals and telehealth in Oklahoma.
How do I appeal IRMAA (higher premiums based on income)?
If your income from two years ago was above the first IRMAA limit ($109,000 for an individual or $218,000 for a married couple filing jointly, for 2026 premiums), Social Security adds an income-related amount to your Part B and Part D premiums. Because the brackets are cliffs, one dollar over a limit raises the whole amount. Social Security, not Medicare, makes this decision, and there are two ways to challenge it:
- Life-changing event (Form SSA-44). If your income dropped because of marriage, divorce or annulment, the death of a spouse, stopping or reducing work, the loss of income-producing property, or the loss of a pension, ask Social Security for a new decision using a more recent year's income. You need proof of the event and of the lower income. This is common in the first years after retirement.
- Reconsideration. If the tax information Social Security used is wrong, or you disagree for another reason, ask for a reconsideration within 60 days of receiving the notice.
Estimate your bracket with our IRMAA calculator, and contact Social Security at 1-800-772-1213 (TTY 1-800-325-0778) or an Oklahoma Social Security office to file.
How do SoonerCare appeals work?
If you have both Medicare and SoonerCare, each program has its own appeals. Medicare decisions follow the steps above. For a SoonerCare decision by the Oklahoma Health Care Authority (OHCA), OHCA's rule OAC 317:2-1-2 says:
- File form LD-1. Send the LD-1 (Member Complaint/Grievance Form) within 30 calendar days of the date OHCA sends written notice of its action. If there was no notice, the 30 days start when you knew or should have known the facts behind the appeal.
- Prepare for the hearing. The preferred method is a telephone hearing, and you must take part by phone or in person.
- Ask for an in-person hearing if you want one. File form LD-4 in writing at least 10 calendar days before the scheduled hearing date.
Questions about a SoonerCare notice go to the SoonerCare Helpline, 1-800-987-7767. See SoonerCare and Medicare.
What about complaints that aren't appeals?
If your problem isn't a coverage or payment decision, such as long waits, trouble reaching customer service or how you were treated, file a grievance with your Medicare Advantage or Part D plan; your plan's Evidence of Coverage explains how and by when. You can also tell Medicare about a problem with a plan at 1-800-MEDICARE (1-800-633-4227, TTY 1-877-486-2048) or with the complaint form on Medicare.gov.
When should I contact the Oklahoma Insurance Department?
The Oklahoma Insurance Department (OID) regulates insurance companies and licenses agents in Oklahoma. It can't change a Medicare coverage decision. Its Consumer Assistance Division takes requests for assistance about insurance companies and agents, including Medicare supplement (Medigap) insurers, and checks whether a company followed Oklahoma law. OID says it can't order a payout, decide fault or act as your attorney, and it expects you to contact the company first.
Call OID at 1-800-522-0071 or file online at oid.ok.gov. Report problems with Medicare plan sales to 1-800-MEDICARE as well. See Medigap in Oklahoma.
If you suspect fraud
A charge you don't recognize on your MSN or Explanation of Benefits may be a billing error or fraud. Call 1-800-MEDICARE, or contact the Oklahoma Insurance Department's Senior Medicare Patrol for help checking suspicious charges and reporting fraud. See Medicare fraud in Oklahoma and Oklahoma Medicare contacts.
When an appeal isn't the answer
If a plan keeps denying a drug or service you need, or a doctor you rely on leaves its network, it may make sense to change plans during an enrollment period you qualify for. A licensed insurance agent who works with Benefits Life can explain plans from the companies they work with and when you can switch, at no cost to you; you can request a call from a licensed insurance agent. For the appeal itself, follow the instructions on your notice and call 1-800-MEDICARE with questions.

Frequently asked questions
How long do I have to appeal a Medicare denial?
For Original Medicare, file the first appeal by the date on your Medicare Summary Notice. For a Medicare Advantage or Part D plan denial, file within 65 days of the date on the plan's notice. The second Original Medicare level allows 180 days, and later levels generally must be requested within 60 days.
Who handles hospital discharge appeals in Oklahoma?
Acentra Health, the Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO) for Oklahoma, at 1-888-315-0636 (TTY 711). Call no later than your planned discharge day, following the directions on the Important Message from Medicare. If you ask on time, you can stay while it decides without paying for the extra days, other than usual deductibles or coinsurance.
Can the Oklahoma Insurance Department overturn a Medicare denial?
No. Medicare coverage decisions follow the federal appeals process. The Oklahoma Insurance Department takes complaints about insurance companies and agents, including Medicare supplement (Medigap) insurers, at 1-800-522-0071 or online, and checks whether the company followed Oklahoma law. It can't order a company to pay.
How do I appeal a SoonerCare decision?
The Oklahoma Health Care Authority's rule (OAC 317:2-1-2) says a SoonerCare member files form LD-1 within 30 calendar days of the date OHCA sends written notice of its action. Hearings are usually by telephone; to ask for an in-person hearing, file form LD-4 at least 10 calendar days before the hearing date. Medicare decisions still follow Medicare's process.
How do I appeal IRMAA?
IRMAA is decided by Social Security, not Medicare. If your income dropped because of a life-changing event such as retirement, the death of a spouse or divorce, ask Social Security for a new decision with Form SSA-44. If you think the information Social Security used is wrong, request a reconsideration within 60 days of the notice.
