The hospital changed her from inpatient to observation: what you can appeal, and what it costs in nursing-home coverage

This is about Original Medicare. Medicare Advantage plans run their own appeal processes and many of them waive the three-day rule entirely, so if she is in a plan the answer comes from the plan, not from any of the rules below.

Observation is outpatient care delivered in a hospital bed

The word does most of the damage. "Observation services" sounds like a short watchful pause, and in the record it means something narrower: the hospital is treating this as outpatient care. The stay is billed under Part B rather than Part A, and every drug, test and hour of nursing is an outpatient item.

On the hospital bill alone that is not always worse. Medicare's own notice says the outpatient bill may come out lower or higher than the Part A inpatient deductible, depending on the Part B coinsurance owed across the services. Where it is unambiguously worse is if she was not enrolled in Part B when she was hospitalised — then nothing covers the stay and the hospital charges her the full cost of it.

Why four nights in a hospital can still leave no nursing-home coverage

Medicare pays for a skilled nursing facility only after a qualifying inpatient hospital stay. The rule is at 42 CFR 409.30(a)(1): the beneficiary must have been hospitalised for medically necessary inpatient care "for at least 3 consecutive calendar days, not counting the date of discharge". Admission day counts, discharge day does not, and observation time counts for nothing.

So the arithmetic that surprises families is not a mistake. Four nights in the building, two of them as an inpatient and two after the status changed, produces a two-day qualifying stay and no coverage. She must also be admitted to the facility within 30 calendar days of leaving hospital under 42 CFR 409.30(b)(1). Both conditions are counted mechanically, and neither has anything to do with how ill she was.

The court won an appeal against reclassification, not against observation

All of this comes out of a class action filed in 2011. In Alexander v. Azar, 613 F. Supp. 3d 559 (D. Conn. 2020), affirmed sub nom. Barrows v. Becerra, 24 F.4th 116 (2d Cir. 2022), the district court held that beneficiaries are not entitled to appeal rights for their placement as outpatients receiving observation services — and then ordered the Secretary to build appeal processes for the narrower group who were formally admitted as inpatients and subsequently reclassified.

That distinction is the whole shape of the right. It is not an appeal against being in observation. It is an appeal against a decision being reversed, which is why the regulation requires that she "was formally admitted as a hospital inpatient in accordance with an order for inpatient admission by a physician or other qualified practitioner" before anything else applies.

The notice she gets is not the notice that carries the appeal

There are two notices and they do different jobs, which is where a lot of families lose time.

The failure mode is quiet. The MOON does state, accurately, that observation affects skilled nursing coverage, so a family that reads it carefully still comes away informed and with no route to do anything about it. Being told is not the same as being able to object — that gap is exactly what the litigation was about.

The fast appeal, while she is still in the hospital

This route opened on 14 February 2025. The request goes to the Beneficiary and Family Centered Care Quality Improvement Organization for the state, administered for Medicare by Acentra Health or Commence depending on where you are, and it can be made in writing or by telephone. The hospital or nursing facility that provided the services cannot act as her representative — a family member or friend can, and so can anyone already holding a power of attorney.

1. 1

   Ask for the Medicare Change of Status Notice

   The hospital must deliver it no later than four hours before release. If it has not arrived, ask the nurse in charge or the case manager for it by name. It carries the phone number you need.

2. 2

   Call the Quality Improvement Organization before she is released

   The request must reach them before release from the hospital. A request made in time also stops the hospital billing her for the disputed services until the appeal, and any reconsideration, is finished.

3. 3

   Stay reachable

   She or her representative must be available to discuss the case. Give a phone number that someone will answer, and expect the call the same day or the next.

4. 4

   Ask the hospital for a copy of what it sent

   The hospital has until noon of the day after it is notified to give the reviewer its records, and must give her a copy or access by close of business the first day after she asks. It may charge a reasonable duplication cost.

5. 5

   If the decision goes against her, ask for reconsideration by noon the next day

   The deadline is noon of the calendar day following notification. Miss it and the reconsideration is still available at any time, but the protection against being billed during the review is lost.

For a timely request the reviewer must decide within one calendar day of receiving all the information it asked for; Medicare tells beneficiaries to expect a decision about two days after filing. The determination binds the hospital and the claims contractor for payment purposes, subject only to the reconsideration.

If she has already left the hospital

Two things are still possible, and one of them has narrowed sharply.

The first is an untimely request for the same expedited review, which can be made at any time. The reviewer then has two calendar days rather than one, and the protection against being billed during the review does not apply. It is the ordinary route for a reclassification that happened recently.

The second was the retrospective process, built for stays that predated the new machinery, reaching admissions from 1 January 2009 to 13 February 2025. It opened on 1 January 2025 and beneficiaries had 365 days to use it.

A retrospective request filed now must carry a written explanation of why it is late, and evidence supporting it. Good cause under 42 CFR 405.932(a)(2)(ii) means a valid reason beyond your control, and filing as soon as the obstruction was resolved. Medicare gives examples: serious illness or hospitalisation, incapacity, a death or serious illness in the immediate family, records destroyed by fire or flood, or being given the wrong information about how to appeal. A late request with no explanation is not accepted at all. CMS has also warned that requests received after 15 May 2026 will face significant processing delays.

Those requests go to a single eligibility contractor — Q2Administrators, at the address on Medicare's page and on form CMS-10885 — which decides only whether she is an eligible party, normally within 60 days of gathering the records. If she is, the appeal is passed to the Medicare Administrative Contractor for a decision on the merits, and from there it follows the ordinary five levels: reconsideration, an Administrative Law Judge, the Medicare Appeals Council, and judicial review. A refusal on eligibility can itself be reviewed within 60 days of the letter.

What winning actually gets her

Less automatically than you would think, and the reason is that the hospital is not compelled to act on the decision.

If she had Part B at the time, a favourable decision does not require the hospital to submit a Part A claim. Where it declines, it keeps the Part B payment, refunds nothing — including any coinsurance and deductible she paid — and she owes nothing further. Where it does submit one, it must first refund what it received for the outpatient services, and she then pays the Part A inpatient deductible instead. If she had no Part B, the hospital must refund payments received from any source whether or not it submits a claim, and a refund due to her should arrive within 60 days of the hospital receiving the decision.

The nursing facility side is where the money usually is. If the appeal included skilled nursing services she or a family member paid for out of pocket, and they are found covered, the facility is told to refund those payments, again within 60 days of receiving the decision. Services already paid for by Medicare, an insurer or any other third party cannot be included — cost-sharing on a covered stay does not count as out of pocket either.

What to gather, and when

That last item is a formal requirement rather than a courtesy: a retrospective appeal including nursing services must attest to the out-of-pocket payments and document them, which is what a sworn affidavit is for. Payments made by a family member count, whether or not they are biologically related.

The classification is a judgement, and judgements can be wrong

What the reviewer decides is whether the inpatient admission met the criteria for Part A coverage on the record as it stood. That is a clinical judgement about the expected length and intensity of care, made under time pressure, sometimes revisited by a utilisation review team days later. It is exactly the kind of decision that ought to be reviewable, and for fourteen years it was not.

The practical consequence is narrow and worth acting on. If she was admitted and then moved to observation, ask for the change of status notice, phone the number on it before she leaves the building, and put the objection in writing the same day — a general legal notice does the job if nobody will take it by phone. If she was never admitted, none of this is available, and the argument to have is with the attending physician while she is still in the bed. Either way the discharge planner is the person to ask about the admission order, and the nursing facility paperwork waiting at the other end carries its own problem.
