Inpatient or observation
What is the difference between being an inpatient and being “under observation”?
You are an inpatient only when a doctor orders your admission and the hospital formally admits you. Observation is outpatient care the doctor uses while deciding whether you need to be admitted, and you can be under observation even while staying overnight in a regular room. The label matters because it changes what Medicare pays and whether rehab afterward is covered.
How does the hospital decide whether to admit someone?
Medicare says inpatient admission is generally appropriate when the doctor expects the patient to need hospital care across 2 or more midnights. Even then, the doctor still has to write the order and the hospital has to formally admit the patient. If you are unsure, ask the doctor directly what your loved one’s status is and why.
How does observation status change what we pay?
An inpatient stay falls under Medicare Part A, while observation and other outpatient services fall under Part B, which has its own deductible and coinsurance. A copayment for any single outpatient service can’t be more than the inpatient deductible, but the total of all outpatient copayments can be. If your family member has Medicare Advantage, call the plan, because its costs may differ.
What is the MOON notice?
The Medicare Outpatient Observation Notice, or MOON, tells a patient they are an outpatient getting observation services and explains how that affects costs and coverage of rehab afterward. The hospital must give it to anyone in observation for more than 24 hours, no later than 36 hours after observation began (or at release, if that comes sooner). Staff must also explain it out loud, and the patient or their representative is asked to sign it.
Does time under observation count toward the 3 days Medicare needs for rehab?
No. Original Medicare only covers a skilled nursing facility stay after at least 3 inpatient days in a row, and observation and emergency room time don’t count, even overnight. That is why it pays to ask about status every day. Some Medicare Advantage plans waive the 3-day rule, so check with the plan.
What if the hospital switches my parent from inpatient to observation during the stay?
For stays on or after February 14, 2025, the hospital should give a Medicare Change of Status Notice before your family member leaves. It explains the change and the right to a fast appeal to the Medicare reviewer for Utah, Acentra Health, and filing while still in the hospital is best. A decision usually comes about 2 days after you file.
How do we find out which status my loved one has?
Ask the doctor, the nurse, the hospital social worker or case manager, or the patient advocate. Medicare suggests asking every day of the stay, since status can change. Write down who told you and when.
How discharge planning works
What does a hospital discharge planner do?
Discharge planners, often nurses or social workers, figure out what care your loved one will need after leaving, such as home health, rehab in a skilled nursing facility, hospice, or help in the community. Federal rules require the hospital to spot patients at risk early in the stay, evaluate their needs, involve the patient and caregivers, and update the plan as things change. At discharge, the hospital must send needed medical information to the next providers.
When does discharge planning start, and can we ask for it?
The hospital is supposed to identify patients who need a discharge plan early in the stay. A patient, their representative, or their doctor can also ask for a discharge planning evaluation, and the hospital must do one. If no one has talked with you about the plan by the second day, ask for the case manager.
Do we get a say in the discharge plan?
Yes. Federal rules say the plan must focus on the patient’s goals and treatment preferences, with the patient and caregivers treated as active partners. Tell the planner plainly what support is and isn’t available at home, since the plan should reflect real life. If something in the plan won’t work, say so before the discharge day.
Can we choose the rehab facility or home health agency?
Yes. When a patient needs home health, a skilled nursing facility, an inpatient rehab facility or a long-term care hospital, the hospital must give a list of available Medicare-participating options in your area and tell you that you are free to choose. It must respect your preferences when possible, may not limit your options, and must help you compare quality information that fits your goals.
Does the hospital have to tell us about its own business ties?
Yes. The discharge plan must point out any home health agency or skilled nursing facility in which the hospital has a disclosable financial interest, and any that has a financial interest in the hospital. Being owned by the same system doesn’t make a provider good or bad, but you deserve to know.
What if my parent has a Medicare Advantage plan?
The hospital should tell you to check which providers are in your plan’s network and share any network information it has. Most plans also need to approve rehab or home health before it starts. Call the number on the plan card early so approval doesn’t hold up the discharge.
What if our first choice can’t take my parent?
Each facility or agency decides whether it can accept a patient based on open space and the care needed. Ask the planner to send referrals to several choices at once so you have a backup. Utah Care Network can also help you find options at no cost to you.
Your discharge rights and appeals
What is the “Important Message from Medicare”?
It is a notice called “An Important Message from Medicare about Your Rights” that explains a patient’s right to appeal a discharge they think is too soon. The hospital should give it within 2 days of admission and again before discharge. If you didn’t get one, ask for it.
How do we appeal if we think the discharge is too soon?
Follow the steps on the Important Message and contact the Medicare reviewer for Utah, Acentra Health, no later than the day of the planned discharge. If you file on time, your loved one can stay in the hospital during the review without paying for those days, apart from any usual deductibles or coinsurance. The reviewer is independent of the hospital.
What happens after we request the appeal?
The reviewer tells the hospital, and the hospital must give you a Detailed Notice of Discharge by noon the next day explaining its reasons. The reviewer generally decides within one day of getting the information it needs. If it agrees your loved one should stay, Original Medicare keeps covering the stay for as long as it is medically necessary.
What if the reviewer agrees with the hospital?
If you filed on time, you aren’t responsible for hospital charges through noon of the day after the decision. If your loved one stays longer than that, those days may be your cost. Use that time to finalize the safest plan you can with the discharge planner.
What if we miss the appeal deadline, or have Medicare Advantage?
If you miss the deadline, you can still ask Acentra Health for a review, but different rules apply and you may owe for days past the original discharge date. People with Medicare Advantage can also appeal through their plan, and plan rules differ. Utah SHIP counselors can walk you through your options at no charge.
Going home or going to rehab
How do we decide between going home and going to rehab?
It depends on what skilled care your loved one still needs, how much therapy they can handle, how safe their home is, and how much help family can give day and night. Insurance rules also play a part. Ask the doctor and therapists what they recommend and why, and ask what would need to be true for home to be safe.
What can home health care provide after a hospital stay?
Medicare home health covers part-time or occasional skilled nursing and therapy at home for people who are homebound, after a doctor or other provider examines them and orders it. Covered home health services cost $0, though equipment carries the usual 20% after the Part B deductible. It does not cover 24-hour care, meal delivery, housekeeping, or personal care like bathing when that is the only help needed.
What is the difference between inpatient rehab and a skilled nursing facility?
An inpatient rehabilitation facility is for people who need intensive therapy, ongoing doctor supervision, and coordinated team care, and a doctor must certify that need. A skilled nursing facility generally provides nursing care with therapy at a gentler pace. Under Original Medicare, if your loved one moves directly from the hospital to inpatient rehab, they don’t pay a new deductible.
What if Medicare won’t cover rehab because there wasn’t a 3-day inpatient stay?
Ask the hospital team whether home health could meet the need, since it has different rules. If your loved one has Medicare Advantage, ask whether the plan waives the 3-day rule. Medicare also suggests asking whether Medicaid or veterans’ benefits could help pay for skilled nursing care.
Before you leave the hospital
What should we ask before leaving the hospital?
Ask which medicines are new, changed or stopped, and why. Ask when follow-up appointments are, what warning signs mean you should call or come back, and who to call after hours. Get the start date and contact information for any home health agency or rehab facility, and get everything in writing.
Who gets the discharge paperwork?
The hospital must send necessary medical information to the providers who will care for your loved one next. Ask for your own copy of the discharge summary and medication list, and bring them to the first appointment with the primary care doctor. This catches gaps when records don’t arrive in time.
How do we get a walker, wheelchair or hospital bed for home?
A doctor or other provider must order the equipment, and Medicare only pays suppliers that are enrolled in Medicare. Ask the supplier whether it accepts assignment, which keeps your share to the coinsurance and deductible. Try to have equipment delivered and set up before your loved one gets home.
What if we don’t feel it’s safe to take my parent home?
Tell the discharge planner and the doctor right away, and explain exactly what worries you. Ask them to re-evaluate the plan and consider other options such as rehab or added home services. If you think the discharge is too soon, you have the right to the fast appeal described above.
