Observation status, and why it is the expensive question

Observation is an outpatient service that happens in an inpatient-looking bed. The hospital bills it under Part B rather than Part A, and the days do not count toward the three-day inpatient stay that Medicare's skilled nursing benefit requires. Nothing about the room, the staff or the treatment tells a family which one is happening.

Because it was invisible, Congress required a warning. Where observation services run more than 24 hours, the hospital must give written notice not later than 36 hours after they began — sooner if the patient is transferred, discharged or admitted — explaining the outpatient status, the reason for it, and what it means both for cost-sharing and for later eligibility for skilled nursing cover.

If you are handed this notice, treat it as a decision point rather than a form. Ask whether the treating physician considers inpatient admission appropriate, and ask while the patient is still in the hospital.

This is the difference that costs families thousands of dollars, and it is decided by a status they were never asked about.

What the hospital is required to do before it discharges anyone

Discharge planning is a condition a hospital must meet to participate in Medicare at all. The regulation requires a process that centers the patient's own goals and treatment preferences and treats the patient and their caregivers as active partners in planning — which is a standard, not a courtesy, and can be asked for by name.

Things you may ask for, and the hospital must provide

  • A discharge planning evaluation, on the request of the patient, their representative or their physician — not only for patients the hospital picked out.
  • The results of that evaluation discussed with the patient or their representative, and recorded in the medical record.
  • Re-evaluation when the patient's condition changes, and an updated plan to match.
  • A list of Medicare-participating home health agencies, nursing facilities, rehabilitation facilities or long-term care hospitals serving the area — not a single name.
  • Help using published quality and resource-use data to choose between them.
  • A clear statement of your freedom to choose among participating providers, which the hospital may not limit.
  • Disclosure in the discharge plan of any agency or facility on that list in which the hospital has a financial interest.

If a parent is in a Medicare Advantage plan, ask which of the listed providers are in the plan's network. The hospital must make you aware that this needs checking, and must share what it knows.

The appeal: free, by telephone, and the hospital has to prove its case

The right arises whenever a hospital, with a physician's concurrence, decides inpatient care is no longer necessary. It is exercised by contacting the Quality Improvement Organization named on the notice — in writing or by telephone — no later than the day of discharge.

  1. Call the QIO number on the notice. Say that you are requesting an expedited determination of a discharge decision.
  2. Stay put. The liability protection assumes the patient is still in the bed past midnight of the ordered discharge date.
  3. Read the detailed notice the hospital must deliver by noon the next day, which has to say specifically why the care is no longer covered.
  4. Ask for copies of what the hospital sent the QIO if you want to see the case being made.
  5. Expect a decision within one calendar day of the QIO having what it asked for, delivered first by telephone and then in writing.

The deadline buys the protection, not the right. A patient still in the hospital can ask at any time, and one already home can ask within 30 calendar days — but in both cases the rule that stops the hospital billing for the disputed days does not apply.

Nothing about this process requires a lawyer, a form, or a fee. The regulation deliberately allows a telephone call and does not require the family to submit any evidence at all, because the burden of proof rests with the hospital.

What to do, and when

Ordered by the hospital's own clock rather than by importance. Two of these have deadlines set by federal regulation, and missing them costs a protection rather than the right itself.

The first two days

Within 2 calendar days of admission

Almost everything that goes wrong later is decided here, quietly.

  1. Ask on the first day, and again if the stay is extended

    Ask, in words, whether she has been admitted as an inpatient or is under observation

    They look identical from the bed — same ward, same drip, same wristband — and they are different Medicare benefits. Observation is an outpatient stay. If observation lasts more than 24 hours the hospital must give written notice within 36 hours saying so and explaining what it means for cost-sharing and for later nursing-home cover.
    • The notice is a standard form. If nobody has handed you one after a day in the hospital, ask the nurse in charge whether the stay is inpatient or observation and write down the answer and who gave it.
    • A physician can change the status to inpatient while the patient is still in the hospital. It is much harder afterwards, which is why the question belongs on day one rather than at discharge.

    Days spent under observation do not count toward the three inpatient days Medicare's rehabilitation benefit requires. Families discover this at the rehab admissions desk, after the decision has been made.

  2. Within 2 calendar days of admission

    Get, read and keep the notice of discharge appeal rights

    The hospital must deliver it at or near admission and no later than two calendar days after, and must have the patient or their representative sign for it. It is the document that names the organization to call and the deadline for calling them.
    • Photograph both sides. The number for the Quality Improvement Organization is on it, and it is the one thing you will need in a hurry later.
    • If a parent cannot take it in, a representative may sign instead. Signing acknowledges receipt — it is not agreement with anything.

    Do after: inpatient or observation

  3. Make sure the hospital has recorded who speaks for her

    The appeal, the detailed explanation and the copies of records all go to the patient or the patient's representative. If nobody is recorded, everything goes to a parent who may be too unwell to act on it.
    • A health-care agent under an advance directive or proxy is the cleanest answer. Where none exists, ask what the hospital requires to record a representative and do it that day.

    Do after: get the notice

During the stay

From admission until a discharge date is named

  1. Ask for a discharge planning evaluation, in those words

    The hospital must provide one for patients it identifies as at risk, and also for any other patient on the request of the patient, their representative or their physician. Asking puts it in the medical record, and the result must be discussed with you.
    • Ask who the discharge planner or case manager is by name, and how to reach them directly. In most hospitals this is one person and finding them takes days if you wait.

    Do after: name yourself

    It converts an informal conversation into a documented process the hospital is required to run and to re-run when the patient's condition changes.

  2. Ask for the list of agencies and facilities, not a recommendation

    Where home health, a skilled nursing facility, an inpatient rehabilitation facility or a long-term care hospital is indicated, the hospital must give a list of those participating in Medicare that serve the area, must help you use quality and resource-use data to choose, and must not limit which ones are available to you.
    • If you are handed one name, ask for the list. Being given a single provider is a frequent quiet failure of this rule.
    • The discharge plan must identify any agency or facility on the list in which the hospital has a disclosable financial interest. It is fair to ask that question out loud.

    Do after: ask for evaluation

  3. Say out loud what home actually looks like

    The evaluation is supposed to cover the patient's likely need for services after discharge and whether those services are actually available to them. Stairs, a bathroom on the wrong floor, nobody in the house overnight and a two-hour drive are facts about availability, not complaints.
    • Put it in writing to the case manager as well as saying it. A discharge plan that never recorded the stairs is much harder to argue with later.

    Do after: ask for evaluation

When a discharge date is named

Up to 2 days before discharge

  1. Not more than 2 days before discharge

    Expect the second copy of the notice, and treat it as the warning

    The hospital must present a copy of the signed notice before discharge, as far in advance as possible and not more than two calendar days before. In practice that second copy is the signal that a discharge date has been decided.

    Do after: get the notice

  2. Hard to undo

    Decide, that day, whether the discharge is safe

    The question is not whether more hospital time would be nice. It is whether the patient still needs care at the inpatient hospital level, or whether the plan for after discharge is one that actually exists. If either answer is no, the appeal is free and the deadline is short.

    Do after: second notice

    The deadline for the protected version of the appeal is the day of discharge. After that the right survives but the protection against being billed does not.

The appeal, if you make one

By the day of discharge

None of this costs anything, and none of it requires a lawyer.

  1. No later than the day of discharge

    Call the Quality Improvement Organization on the notice

    The request may be made in writing or by telephone and must be made no later than the day of discharge. You may submit evidence but are not required to. The hospital then has to prove that discharge is the correct decision.
    • Write down the time of the call and the name of the person who took it.
    • Staying in the bed past midnight of the discharge date is part of how the protection works. Do not leave and then appeal.

    Do after: decide whether to appeal

  2. Read the detailed notice the hospital must then give you

    Once the QIO tells the hospital an appeal has been made, the hospital must deliver a detailed written explanation by no later than noon the next day, saying specifically why the care is no longer covered and which Medicare rule it is relying on.
    • You may also ask for a copy of, or access to, everything the hospital sent the QIO, including notes of anything given by telephone. The hospital must provide it by close of business the following day and may charge a reasonable copying cost.

    Do after: call the qio

  3. Expect a decision within a day, and know what it costs either way

    The QIO decides within one calendar day of receiving the information it asked for. Where the request was timely, the patient is not financially responsible for the inpatient stay beyond the ordinary coinsurance and deductible until noon of the day after the decision is delivered.
    • If the decision goes against you and the patient is still an inpatient, a reconsideration may be requested. If they have already gone home, the ordinary Medicare claims appeal route remains open.

    Do after: call the qio

After discharge

Up to 30 calendar days

  1. If the moment passed, the review is still available

    A patient who is no longer in the hospital may still ask the QIO to review the discharge within 30 calendar days, or later for good cause. The decision then takes up to 30 calendar days and the protection against liability does not apply — but the review itself still happens.

    Do after: the decision

  2. Expect the same machinery again at rehab or home health

    A skilled nursing facility, home health agency or hospice must give written notice at least two days before it stops Medicare cover, and that notice carries its own appeal with a deadline of noon the following day. It is a different form and the same idea.

    Do after: late appeal

Questions people ask about this

  • They gave us the name of one nursing home and said to call today.

    Ask for the list. Where a skilled nursing facility is indicated, the hospital must give a list of Medicare-participating facilities serving the area you ask about, must help you use quality data to compare them, and must not specify or otherwise limit which ones are available to you. It must also disclose in the discharge plan any facility on that list in which it has a financial interest.1

  • We missed the deadline to appeal. Is that the end of it?

    No. A patient still in the hospital may request a review at any time during the stay, and a patient who has already left may request one within 30 calendar days of discharge, or later for good cause. What is lost by missing the deadline is the protection against being charged for the disputed days, not the review itself.3

  • Nobody gave us any notice at all.

    Say so, to the case manager and to the QIO if you call. The hospital must deliver the notice within two calendar days of admission, must obtain a signature for it, and must present a copy again before discharge. Whether valid notice was given is one of the specific things the QIO checks when it reviews a discharge.23

  • She is medically ready but there is nobody at home. Does that count?

    It is worth raising, and it belongs in the discharge planning evaluation rather than in the appeal. The evaluation must cover the likely need for services after discharge and whether those services are actually available to the patient. An appeal to the QIO asks a narrower question — whether inpatient hospital care is still needed — so the stronger route is usually to insist on the evaluation, in writing, and to name what is missing.1

  • She has a Medicare Advantage plan. Is any of this different?

    The discharge planning duties are the hospital's and apply the same way. The appeal route differs in its detail, and the notice you are given will name the organization to contact. Two things are worth doing early: ask which listed providers are in the plan's network, which the hospital must make you aware of checking, and read the notice you are handed rather than assuming it is the same form.
