Medicare denied your care. Here's how the 2026 appeal works in Montrose County

Nine out of ten Medicare Advantage denials are never appealed. Of the ones that are, four out of five get overturned. The whole game is knowing which notice you are holding, which clock it started, and who decides next.

The short answer

Every Medicare denial can be appealed, and there are five levels of appeal. In Original Medicare you have 120 days from the date you get the notice — usually your Medicare Summary Notice — to ask for a redetermination. If a Medicare Advantage plan or a Part D drug plan denied you, you have 65 days from the date on the plan's denial letter. If care you are already getting is being cut off — a hospital discharge, the end of rehab, the end of home health — you are on a much shorter clock and you want a fast appeal from Colorado's quality improvement organization, Acentra Health, at 1-888-317-0891.

What follows is the whole ladder in plain English: which road you are on, what each notice means, what the deadlines are, what the federal data says about your odds, and the two deadlines that are measured in hours instead of months. Every figure links to Medicare.gov, CMS, the Federal Register, the HHS Inspector General, or KFF. This is education, not advice.

Which appeal am I on? Three roads, one ladder

Before anything else, answer one question: who said no? If a claim was denied after the fact and the news arrived on a Medicare Summary Notice, you are in Original Medicare and you are arguing with a claims contractor. If a plan refused to authorize something in advance, or refused to pay, you are arguing with the plan first. Everything downstream — deadlines, who reviews it, whether the next level happens automatically — depends on that answer.

Sources: Medicare.gov — Appeals in Original Medicare · Medicare.gov — Appeals in Medicare health plans · Medicare.gov — Appeals in a Medicare drug plan · CMS — First Level of Appeal: Redetermination by a Medicare Contractor. Plans may extend a Medicare Advantage or Part D decision by up to 14 days in limited circumstances, and must tell you in writing if they do.

Two differences in that table matter more than the rest.

Medicare Advantage escalates itself; Part D does not. If your Medicare Advantage plan denies your level 1 appeal, Medicare.gov states the plan must automatically forward the case to an Independent Review Entity for a level 2 review. You do nothing. A Part D drug plan has no such rule — if your redetermination is denied, the clock starts on you, and you have 60 days to file with the Part D Independent Review Entity yourself. People lose drug appeals by assuming the machinery keeps running. It does not.

Your doctor can start a Medicare Advantage appeal for you. For a service you have not received yet, Medicare.gov says your doctor can ask for a reconsideration on your behalf and must notify you about it. For a Part D drug, your prescriber's supporting statement explaining the medical reason is often what decides the case. Neither happens automatically. You have to ask.

Every notice Medicare sends, and the clock each one starts

Medicare communicates almost entirely through named forms, and the name is the key that unlocks the right phone tree. Here is the set you are likely to see, what each one does, and what it starts running.

Sources: Medicare.gov — Medicare Summary Notice (MSN) · Medicare.gov — Fast appeals · CMS — Fee-for-Service Advance Beneficiary Notice of Noncoverage (Form CMS-R-131) · Medicare.gov — Appeals in Medicare health plans · CMS — Interoperability and Prior Authorization Final Rule (CMS-0057-F) fact sheet.

Two notes on that list that save real money.

The Medicare Summary Notice arrives every six months. Medicare.gov describes it as a notice people with Original Medicare get in the mail at least twice a year. That means a denial can be four months old before you ever see it — and your 120 days window runs from when you receive the notice, not from the date of service. If you want to catch denials faster, switch to electronic notices, which arrive by email in any month you have a processed claim.

An ABN is not a denial. An Advance Beneficiary Notice of Noncoverage is a warning your provider gives you before a service, in Original Medicare, when they expect Medicare will not pay. It is not a Medicare decision and there is nothing to appeal yet. The three options on the form matter: Option 1 says you want the item and you want the claim submitted to Medicare anyway. Choose that one if you disagree, because it produces a formal Medicare decision — and a formal decision is an appealable one. Signing without reading is how people convert an arguable claim into a bill they agreed to pay.

The five levels, and where cases actually end

The ladder below is written for Original Medicare. Medicare Advantage and Part D use different names for the first two rungs, but levels 3, 4, and 5 are identical across all three — the same judges, the same council, the same court.

Sources: Medicare.gov — Appeals in Original Medicare · Federal Register — Medicare Appeals: Adjustment to the Amount in Controversy Threshold Amounts for Calendar Year 2026 — the calendar year 2026 amount-in-controversy thresholds took effect January 1, 2026, rising from $190 and $1,900 in 2025.

Notice the two dollar thresholds. To get a hearing before an administrative law judge in 2026, the amount in dispute must be at least $200. To get into federal district court, at least $1,960. Those figures are adjusted every year by the medical care component of the consumer price index and published in the Federal Register. There is no threshold at levels 1, 2, or 4 — a $40 lab bill gets the same first two reviews as a $40,000 hospital stay.

In practice, almost nothing travels the whole ladder. Most denials that get reversed get reversed at level 1 or level 2, usually because someone finally attached the piece of paper that was missing the first time — a chart note, a prescriber's statement, a corrected billing code. Before you file anything, Medicare.gov's own first instruction is worth taking literally: ask your provider or supplier for any information that would make your appeal stronger. The appeal is not a debate. It is a documentation problem.

The numbers that should change your mind about appealing

Prior authorization is a Medicare Advantage feature. Original Medicare, with narrow exceptions, does not require a plan's permission before you get care — which is one of the real differences between the two, and one we walk through in our Medigap versus Medicare Advantage comparison. If you are in a Medicare Advantage plan, here is the scale of the system you are inside.

Source: KFF — Medicare Advantage Insurers Made Nearly 53 Million Prior Authorization Determinations in 2024 (January 28, 2026), an analysis of prior authorization data reported to CMS by Medicare Advantage insurers for calendar year 2024.

Put the second and fourth numbers next to each other and the picture is uncomfortable. Roughly nine of every ten denials are simply accepted. Among the small minority that are challenged, the great majority are reversed. KFF also found wide variation between insurers — denial rates ran from 4.2% to 12.8%, and appeal rates from 1.6% to 19.9% — which means how likely you are to be denied, and how likely your neighbors are to push back, depends partly on whose card is in your wallet.

The pattern is sharpest exactly where it hurts most: getting into rehab after a hospital stay.

Sources: KFF — Medicare Advantage Insurers Made Nearly 53 Million Prior Authorization Determinations in 2024 (January 28, 2026) (all prior authorization appeals, calendar year 2024) · HHS Office of Inspector General, OEI-09-24-00331 and OEI-09-24-00330 (post-acute care requests, June 2024). Bars show the share of appealed denials decided in the enrollee's favor, not the share of all requests.

The Inspector General's June 2026 data brief examined every prior authorization request for skilled nursing facility admission that 19 Medicare Advantage organizations handled in June 2024. Plans denied 12% of those requests. Enrollees and providers appealed 18% of the denials. And when they did, plans overturned 95% of them in the enrollee's favor. The Inspector General's own framing is that an overturn rate that high raises concerns about whether the initial denials should have been issued at all.

Read practically: if your plan denies a skilled nursing admission after a hospital stay, the single most likely outcome — if you appeal — is that the denial gets reversed. The cost of not appealing is a rehab stay you pay for yourself, or one you never get.

The fast appeal: when they are sending you home too soon

This is the section to read twice, because the deadlines are measured in hours and the notice that starts them is easy to mistake for paperwork.

Medicare.gov describes the right to a fast appeal in five settings: a hospital, a skilled nursing facility, a home health agency, a comprehensive outpatient rehabilitation facility, and a hospice. Instead of your plan or a claims contractor reviewing the decision, an independent reviewer does — a Beneficiary and Family Centered Care Quality Improvement Organization, or BFCC-QIO. In Colorado that organization is Acentra Health, and the beneficiary helpline is 1-888-317-0891.

In a hospital. Within two days of admission you should get a notice called "An Important Message from Medicare about Your Rights." If you are being discharged more than two days later, the hospital must give you a copy of your signed notice, or a new one, before you go. To appeal, follow the directions on that notice no later than the day you are scheduled to be discharged. Do that and you can stay in the hospital while the reviewer decides, and you will not owe for the stay beyond the coinsurance and deductibles you would owe anyway. The reviewer decides within one day of getting the information it requested. If you miss the deadline you can still ask for a review, but different rules apply and you may owe for the days past the original discharge date.

In a nursing home, in rehab, or on home health. You should get a "Notice of Medicare Non-Coverage" at least two days before your covered services end. If nobody hands you one, ask — Medicare.gov says so explicitly. To appeal, follow the instructions on it no later than noon the day before the termination date printed on the notice. That is the deadline people miss, because a notice handed over on a Friday for a Monday end date reads like it can wait until Monday. It cannot. After you file, the provider must give you a "Detailed Explanation of Non-Coverage" by the end of the next business day, spelling out which Medicare rule they say applies to you, and the reviewer decides by close of business the day after it has what it needs.

If you miss the QIO deadline and you are in a Medicare Advantage plan, you can still request a fast reconsideration from the plan — but Medicare.gov warns that services will only be covered if the decision comes out in your favor. The QIO route protects you while you wait. The plan route does not.

One related trap has its own procedure: being kept in the hospital "under observation" rather than admitted as an inpatient. That is not a discharge appeal, it is a status question, and it decides whether Medicare will pay for nursing home rehab afterward. We cover it in detail in the observation-status guide.

Why this lands hard in Montrose County

Two local facts turn an abstract federal process into a concrete problem here.

First, most of the county's exposure to prior authorization is real. CMS counted 13,031 Medicare beneficiaries in Montrose County in calendar year 2025 — 5,710 of them, or 43.8%, in a Medicare Advantage or other health plan, and 7,321 in Original Medicare. Nearly half the county is in the kind of coverage where a plan gets to say yes or no before the care happens. The other half will mostly meet denials the slower way, on a Medicare Summary Notice, months later.

Second, if a rehab admission is denied, the local alternatives are thin. The CMS Provider Data Catalog file of Medicare-certified nursing homes, processed July 1, 2026, lists three in Montrose County — two in Montrose and one in Olathe — with 257 certified beds between them. Here is how that compares across the six counties this agency serves.

Source: CMS Provider Data Catalog — Nursing homes including rehab services (Provider Information) — certified bed counts for Medicare- and Medicaid-certified nursing homes by county, file processing date July 1, 2026. Counts reflect certified beds, not beds available on any given day.

Certified beds are not open beds. A county with 257 certified beds may have very few free on the afternoon a hospital in Montrose or Grand Junction is ready to discharge you, and Ouray and Pitkin counties have no Medicare-certified nursing home at all — which means a Ridgway or Aspen family is already looking at a drive before a plan ever weighs in. In that setting, a denied prior authorization is not just a bill. It is a bed that goes to someone else while you argue. That is the practical case for filing the fast appeal the same day the notice appears, not the next business day.

Source: CMS — Medicare Monthly Enrollment (data.cms.gov) — calendar year 2025 annual figures by county of residence. The CMS "Medicare Advantage and other health plan" category includes cost plans and similar arrangements; the remainder are in Original Medicare.

What changed on January 1, 2026

Two changes took effect this year, and both help the person filing the appeal.

Faster decisions. Under the CMS Interoperability and Prior Authorization final rule — CMS-0057-F — affected payers, including Medicare Advantage plans, must send prior authorization decisions within 72 hours for expedited requests and within seven calendar days for standard requests. The compliance date was January 1, 2026.

A specific reason for the denial. The same rule requires payers to include a specific reason when they deny a prior authorization request. CMS's stated purpose is to help you resubmit the request or file an appeal. This is a bigger deal than it sounds. A denial that says only "not medically necessary" gives you nothing to answer; a denial that names the criterion you failed tells your doctor exactly which chart note to send.

And public metrics. Payers must publicly report prior authorization data, with the first set due by March 31, 2026 — the same reporting stream that produced the KFF figures above.

None of this changed your appeal rights, your levels, or your deadlines. It changed the speed and the transparency. The deadlines in this article are still the ones that govern.

Part D: the drug denial and the exception request

Drug denials work a little differently, and the difference is a word: exception.

A coverage determination is the plan telling you whether a drug is covered and what you will pay. An exception is a specific kind of request: you are asking the plan to cover a drug that is not on its formulary, to waive a step-therapy or quantity restriction, or to charge you a lower cost-sharing tier. Medicare.gov is direct about the requirement — if you are asking for an exception, your prescriber must provide a statement explaining the medical reason it should be approved. Without that statement, an exception request is very likely to fail. With it, it frequently succeeds.

The clocks: you, your representative, or your prescriber must ask for a redetermination within 65 days of the date on the plan's denial notice. Standard benefit appeals get a decision in 7 days, payment appeals in 14 days, and a fast appeal in 72 hours if waiting could seriously jeopardize your health. And remember the difference from Medicare Advantage: if your drug plan denies the redetermination, nothing forwards automatically. You have 60 days to file with the Part D Independent Review Entity yourself.

One thing worth checking before you appeal at all: whether the drug is expensive because of where you are in the year rather than because of a denial. The 2026 Part D out-of-pocket cap changes that math considerably, and we break it down in the Part D cap guide.

Appeal, grievance, or quality complaint?

Three different problems, three different destinations, and mixing them up wastes weeks.

• An appeal is about coverage or payment. Medicare or your plan will not cover, authorize, or pay for something and you want that reversed. Everything in this article is about appeals.
• A grievance is a complaint about how you were treated — a plan that will not return calls, a long hold time, a pharmacy that was unhelpful, a problem with the way a plan markets itself. File it with your plan, or with Medicare. A grievance will not get a denied service approved.
• A quality of care concern — you were discharged before you were ready, you got the wrong medication, you believe the care itself was substandard — goes to the Beneficiary and Family Centered Care Quality Improvement Organization. In Colorado that is Acentra Health, at 1-888-317-0891. There is no deadline to raise one, and it is free.

The quick test: if you are asking someone to pay for something, it is an appeal. If you are asking someone to fix how you were treated, it is a grievance. If you are worried the medicine itself was wrong, it is a quality concern. You can pursue more than one at the same time.

How to file, step by step

1. Find the notice and read the date on it. The date printed on the notice — not the date of service, not the date you opened the envelope — is what most deadlines run from. Write the deadline on the envelope.
2. Identify which road you are on. Medicare Summary Notice means Original Medicare and a 120 days window. A letter from your plan means 65 days. A Notice of Medicare Non-Coverage or an Important Message from Medicare means hours, not months — go to the fast appeal section above and call Acentra Health at 1-888-317-0891 today.
3. Call the provider's billing office first. Medicare.gov's own advice for a denied item on an MSN is to call the office and make sure they submitted the correct information — if they did not, they may simply resubmit, and there is no appeal to file. A surprising share of denials are coding problems.
4. Ask for the documentation that supports you. A chart note, a letter of medical necessity, a prescriber's supporting statement for a drug exception. Medicare.gov tells you to do this before you start, and it is the single highest-value step.
5. Write it down and file it the way the notice says. In Original Medicare, either use the Redetermination Request Form or circle the item on a copy of your MSN, explain in writing why you disagree, and mail it to the address on the last page. With a plan, follow the directions in the denial letter. Always include your name, address, and the Medicare Number from your card, the specific items and dates, and why you think they should be covered.
6. Ask for a fast decision if waiting could hurt you. Both Medicare Advantage and Part D plans must decide within 72 hours if your doctor tells the plan that waiting could seriously jeopardize your life, health, or ability to regain maximum function.
7. Appoint a representative if you want help. An Appointment of Representative form lets an adult child, a friend, or an advocate handle the appeal for you. Medicare.gov links the form from every appeals page.
8. Keep copies of everything and note who you spoke to. Dates, names, and reference numbers. If the case moves to level 2, the file you built is what travels with it.
9. Do not stop at level 1. A denial at level 1 is not the end — it is one of five rungs, and the next one is reviewed by people who had nothing to do with the first decision.

Free help, and what it costs (nothing)

You do not have to do this alone, and none of the help below sells you anything.

• Colorado's State Health Insurance Assistance Program (SHIP), administered through the Division of Insurance, gives free one-on-one Medicare counseling statewide, including help with appeals. Counselors are trained volunteers with no commission and no product.
• 1-800-MEDICARE (1-800-633-4227) can tell you where your appeal sits, what level it is on, and what the next deadline is.
• Acentra Health at 1-888-317-0891 handles fast appeals and quality of care concerns for Colorado, and offers immediate advocacy for problems that can be solved quickly.
• Your prescriber or treating physician. For prior authorization and drug exceptions, the clinician's statement is usually the deciding document. Ask for it directly and ask what criterion the plan cited.

And if what the appeal really reveals is that your plan's rules do not fit the care you actually use, that is a different conversation — one for the Annual Enrollment Period, October 15 through December 7. Our Montrose County AEP action plan covers what you can change and when.

We do not offer every plan available in your area. Any information we provide is limited to those plans we do offer in your area. Please contact Medicare.gov, 1-800-MEDICARE, or your local State Health Insurance Assistance Program (SHIP) to get information on all of your options.
