1. What a denial letter actually is
The letters are all written in the same register. A paragraph of explanation, a reference to a policy document nobody has read, and a conclusion in the passive voice: coverage has been denied. Somewhere further down, usually on the second page and usually in smaller type, is the sentence that matters — the one about your right to appeal and the date by which you have to use it. That sentence is not decoration. It is a legal obligation on the plan, and it is there because the denial is not a decision in any final sense. It is one organisation’s first answer.
You can appeal when Medicare or your plan refuses to cover a service, supply, item or drug you think should be covered; when it refuses to pay for something you have already received; when it changes the amount you are asked to pay; and when it stops paying for something you are still getting and still need. You can also appeal if your plan’s drug management programme labels you “at-risk” and limits your access to certain medications. Each of those is a separate right, and each one has a process attached.1
2. Three systems, not one
Here is the part that nobody explains, and it is the reason good advice about appeals so often turns out to be wrong for the person receiving it. Medicare does not have one appeals process. It has three, and they differ in who you file with, how long you have, how long they take to answer and — crucially — whether anything happens next if you do nothing. All three have five levels. Almost nothing else about them lines up.1
- Original Medicare. You are appealing a claim that has already been processed, and the trigger is your Medicare Summary Notice. Level 1 goes to the Medicare Administrative Contractor.
- A Medicare Advantage or other Medicare health plan. You are appealing a decision by a private insurer. Coverage decisions are called organisation determinations and level 1 is a health plan reconsideration.
- A Medicare drug plan. You are appealing a coverage determination. Level 1 is called a redetermination, and the vocabulary is the least of the differences.
Which one applies to you is decided by the card in your wallet, not by what the service was. The same knee replacement, denied, follows three different routes depending on how the person is enrolled. Work out which system you are in before you do anything else, because the deadline you need is the one attached to that system and no other.
3. If you are in a Medicare Advantage plan
In a Medicare Advantage plan, a coverage decision is called an organisation determination, and you have the right to ask for one — in writing or over the phone — before you get a service, to find out whether it is covered. You, your representative or your health care provider can request it. If the answer is no and you disagree, you file a health plan reconsideration. The deadline is 65 days from the date on the initial denial notice sent by your plan. If the appeal concerns a service you have not had yet, your doctor can file it for you and must let you know they have.2
How long the plan has to answer depends on what kind of appeal it is. A pre-service appeal is 30 days. A payment appeal is 60 days. An appeal about a Part B drug is 7 days. A fast appeal is 72 hours. Any of these can be extended by up to 14 days if the plan needs more information and the extension is in your interest, and the plan has to tell you in writing if it takes one.2
The automatic step people miss
If your Medicare Advantage plan denies your level 1 appeal in whole or in part, it does not end there and you do not have to file anything. The plan must send the case on to an Independent Review Entity, which begins level 2 by itself. A great many people read that second letter as a final refusal and stop, when in fact an outside reviewer who has no relationship with the plan is already reading their file.
4. If it is your drug plan
A drug plan uses different words for the same shape. The coverage decision is a coverage determination; the level 1 appeal is a redetermination. You, your representative or your prescriber must ask for it within 65 days of the date on the denial notice — the same filing window as a health plan. The clocks after that are much shorter: 7 days for a benefits appeal, 14 days for a payment appeal, and 72 hours for a fast appeal if your health could be seriously harmed by the standard wait.3
Then the systems diverge, and this is where the damage is usually done. A drug plan’s denial of your level 1 appeal is not forwarded anywhere. Nothing happens next. You have 60 days from the date of that decision to file a reconsideration with the Part D Independent Review Entity yourself, and if you let those 60 days pass because you assumed it worked the way a health plan appeal works, the case is over.3
Same letter, different position
Two neighbours can get denial letters that read almost identically, one from a Medicare Advantage plan and one from a stand-alone drug plan. The first is already at level 2 without lifting a finger. The second has 60 days to act and no further warning. If you are not certain which kind of plan sent your letter, that is the first thing to establish, not the last.
5. If you are in Original Medicare
In Original Medicare the process starts with your Medicare Summary Notice, the quarterly statement listing what was billed and what Medicare paid. If a claim on it was denied, the level 1 appeal is called a redetermination and it goes to the Medicare Administrative Contractor whose address is on the last page of the notice. You must file by the date printed on the Medicare Summary Notice. If you miss it you can still file and still get a decision, but you have to show good cause — an illness, a disability or an accident that delayed you — rather than simply sending it late.4
You will generally get a decision within 60 days of the contractor receiving your appeal. If it goes your way, the item appears as covered on your next Medicare Summary Notice. If it does not, you get a written Medicare Redetermination Notice, and from the day you receive it you have 180 days to ask a Qualified Independent Contractor for a level 2 reconsideration. That 180 days is far more generous than anything in the plan systems, which is worth knowing, because it is also the deadline people most often assume is shorter than it is.4
6. The clocks, in one table
All of the above in one place. The left-hand column is the thing people get wrong most often: the deadline is counted from the date printed on the notice, not from the day you opened the envelope.
| Medicare Advantage | Drug plan | Original Medicare | |
|---|---|---|---|
| Level 1 is called | Reconsideration | Redetermination | Redetermination |
| You file with | Your plan | Your plan | The claims contractor |
| Deadline to file | 65 days from the notice | 65 days from the notice | The date on your Summary Notice |
| Standard decision | 30 days pre-service, 60 days payment | 7 days benefits, 14 days payment | Generally 60 days |
| Fast decision | 72 hours | 72 hours | — |
| Goes to level 2 | Automatically | Only if you file | Only if you file |
| Deadline for level 2 | None — the plan sends it | 60 days | 180 days |
Beyond level 2 the three systems finally converge. Level 3 is a hearing before an administrative law judge at the Office of Medicare Hearings and Appeals, and the amount in dispute has to meet a minimum — $200 for 2026. Level 4 is a review by the Medicare Appeals Council. Level 5 is judicial review in a federal district court, where the minimum is $1,960 for 2026 and claims can sometimes be combined to reach it.234
Holding a letter you do not understand?
Bring it in. Working out which clock you are on takes about ten minutes.
7. The exception request, which is not an appeal
There is a faster route that is not an appeal at all, and it is badly under-used. If the drug you need is not on your plan’s list of covered drugs, or sits on a tier that puts it out of reach, you or your prescriber can ask the plan to make an exception. That is a coverage determination, not an appeal, which is why it comes before any of the deadlines above rather than after them. Your prescriber has to provide a statement explaining the medical reason the exception should be granted, and that statement is doing most of the work.3
You can ask for it by sending the plan a completed Model Coverage Determination Request form, by writing to them, or simply by calling. You or your prescriber can also ask for the request to be expedited, and it will be if the plan agrees — or if your prescriber tells the plan — that waiting for a standard decision may seriously jeopardise your life, your health or your ability to regain maximum function. Only if the exception is refused does the appeal clock start.3
8. When they are sending you home too soon
A different right applies when the problem is not a bill but a discharge. If you believe your Medicare-covered services are ending too soon — from a hospital, a skilled nursing facility, a home health agency, a comprehensive outpatient rehabilitation facility or hospice — you can ask for a fast appeal, and an independent organisation decides it rather than the provider. These have their own notices and their own deadlines, and they are short.5
- In a hospital. Within two days of admission, and again before you are discharged, you should get a notice called “An Important Message from Medicare about Your Rights”. If you ask for the appeal no later than the day you are scheduled to leave, you can stay in the hospital while the decision is made, and you will not pay for those days beyond the usual coinsurance or deductible.
- Everywhere else. You should get a “Notice of Medicare Non-Coverage” at least two days before your covered services end, and you have to ask no later than noon on the day before the termination date printed on it.
- If the notice never comes. Ask for it. The obligation to give it to you does not lapse because nobody remembered, and the deadline runs off the notice.
The decision is made by a Beneficiary and Family Centered Care Quality Improvement Organization, which is an independent reviewer under contract to Medicare rather than part of the hospital or the plan. In Florida that organisation is Acentra Health, and the beneficiary helpline is 1-888-317-0751, TTY 711. That is the number to have written down before you need it, not after.57
9. The hospital status change nobody mentions
This one is new enough that most people have never heard of it, and it costs real money. Since February 14, 2025, if you were admitted to a hospital as an inpatient and your status was changed during the stay to “outpatient getting observation services”, you have the right to a fast appeal of that change. The hospital must give you a Medicare Change of Status Notice, form CMS-10868, before you leave. If it does not arrive, ask for it.6
The reason it matters is arithmetic rather than principle. An inpatient stay is billed under Part A; an outpatient stay under Part B, where what you owe depends on the coinsurance rather than the inpatient deductible and can land either side of it. And Medicare will only pay for a skilled nursing facility afterwards if the hospital stay counted as inpatient. A change made quietly on the ward can therefore decide whether rehabilitation after the hospital is covered at all. The quality review organisation looks at your records, gives the hospital a chance to explain, and tells you what it has decided about two days after you file.6
File it while you are still there
You keep the right to appeal a status change after you have gone home, but it is considerably easier to do while you are still in the building and the records are in front of everybody. If you cannot find the Change of Status Notice, you do not need it to start — call Acentra Health on 1-888-317-0751 and file anyway.
10. A South Florida lens
Which appeals system you are in is not evenly distributed across South Florida, and the gap between the counties is wide. Palm Beach is the one county of the three where more people are still in Original Medicare than in Medicare Advantage — 192,500 against 177,865. Broward runs the other way, 133,954 to 246,276, and Miami-Dade overwhelmingly so, 129,837 to 394,671. Read as an appeals map rather than an enrolment table, that says something useful: the majority of people in Broward and Miami-Dade are on the 65-day clock with automatic escalation, while a plurality in Palm Beach are working from a Medicare Summary Notice with 180 days to reach level 2.9
It also means the advice circulating in a Miami condominium building is frequently the wrong advice for a neighbour in Boca Raton, and the other way round. If you are helping a parent with a denial, check which card they hold before repeating what worked for you. And if a plan is denying things you reasonably expected it to cover, the Annual Enrollment Period that ends on December 7 is the moment to decide whether to stay — separately from, and without giving up, the appeal already running. If you miss it, Medicare Advantage Open Enrollment runs January 1 to March 31 and gives you a second, narrower chance to move.8
11. What to do this week
If you are holding a denial right now, in order:
- Find the date on the notice. Not the postmark, not the day it arrived. Everything is counted from the printed date, so write it on the envelope along with the deadline that follows from it.
- Establish which system you are in. Medicare Advantage, stand-alone drug plan, or Original Medicare. If you are not sure, the card tells you, and so does the organisation named at the top of the letter.
- Read the instructions in the notice itself. Your plan is legally required to tell you in writing how to appeal, and the address or fax you need is in there.
- Ask the prescriber or provider for support in writing. A note setting out the medical reason is the single thing most likely to change the outcome, and at level 1 it is often the whole case.
- Ask for the fast track if waiting would hurt. Say so explicitly, and have the doctor say so too. That is what moves a 30-day clock to 72 hours.
- Diarise the next deadline the moment you file. Particularly on a drug plan, where nothing is forwarded for you and the 60 days to reach level 2 pass quietly.
- Keep the appeal and the enrollment decision separate. Finish one; use what it taught you for the other before December 7.
12. Frequently asked questions
How long do I have to appeal a Medicare denial?
It depends which system you are in, and the three are not the same. In a Medicare Advantage plan or a Medicare drug plan you have 65 days from the date printed on the denial notice — not from the day it arrived in your letterbox. In Original Medicare the deadline is the date printed on your Medicare Summary Notice. If you miss any of these you can still file, but you have to give a reason for being late, and whether it is accepted is no longer automatic.
Is a denial final?
No. There are five levels of appeal in every one of the three systems, and at each level you get a decision letter telling you how to go to the next one. Level 1 is a review by the plan or by the contractor that processed the claim. Level 2 is a genuinely independent reviewer. Level 3 is an administrative law judge. Level 4 is the Medicare Appeals Council. Level 5 is a federal district court. Most cases that go anywhere are resolved long before the end.
Does my Medicare Advantage appeal go to level 2 automatically?
Yes, and this is the single most useful thing to know. If your plan denies your level 1 appeal in whole or in part, it must forward the case to an Independent Review Entity itself. You do not file anything. Many people read the second denial letter and stop, not realising an outside reviewer is already looking at the file.
Does my drug plan appeal go to level 2 automatically?
No, and this is the asymmetry that catches people. If your drug plan upholds its denial, nothing happens next unless you act. You have 60 days from the date of that decision to file a reconsideration with the Part D Independent Review Entity. A Medicare Advantage member and a drug plan member can get what looks like the same letter and be in completely different positions.
What is a fast appeal and when can I ask for one?
There are two kinds. If you think waiting for a standard decision could seriously harm your health, you can ask your plan for an expedited appeal and it must decide within 72 hours. Separately, if you are being discharged or your services are ending — from a hospital, a skilled nursing facility, home health, a rehabilitation facility or hospice — you can ask the independent quality review organisation for your state to look at it. In Florida that is Acentra Health, on 1-888-317-0751.
What is an exception request, and is it an appeal?
It is not an appeal, which is why it is faster. If a drug you need is not on your plan’s formulary, or is on a tier that makes it unaffordable, your prescriber can ask the plan to cover it anyway — that is an exception, and it is a type of coverage determination. Your prescriber has to supply a statement explaining the medical reason. You only get to an appeal if the exception is refused.
The hospital changed me from inpatient to observation. Can I do anything?
Since February 14, 2025, yes. If you were admitted as an inpatient and your status was changed to outpatient getting observation services during the stay, you have the right to a fast appeal. The hospital must give you a Medicare Change of Status Notice before you leave. The decision matters in money: it determines whether the stay is billed under Part A or Part B, and whether Medicare will pay for a skilled nursing facility afterwards.
Can my doctor appeal for me?
In a Medicare Advantage plan, yes — if the appeal is for a service you have not received yet, your doctor can ask for the reconsideration on your behalf, and must tell you they have done it. In a drug plan your prescriber can ask for a redetermination. In every system you can also appoint a family member or friend as your representative in writing.
Should I appeal or just switch plans in December?
Those are separate tracks and doing one does not close the other. An appeal is about a decision already made, usually about care you have already had or urgently need; changing plans during the Annual Enrollment Period only affects next year. If a plan has denied something you need, finish the appeal and treat the denial as information about whether to stay — a plan that fights you on a routine service in October will do it again in March.
Where can I get help with an appeal?
Start with the plan itself: it must tell you in writing how to appeal, and the instructions are in the denial notice. For general questions call 1-800-MEDICARE (1-800-633-4227), TTY 1-877-486-2048. For a discharge or a hospital status change in Florida, call Acentra Health on 1-888-317-0751. And if you want a person in Broward, Miami-Dade or Palm Beach to read the letter with you and work out which clock you are on, that is a conversation we have at no charge.
