What should I do when Medicare says my parent is "ready for discharge"? (2026)

When a hospital says a Medicare-covered parent is ready for discharge, the caregiver has roughly 48 hours to protect coverage. Confirm inpatient vs. observation status, count qualifying midnights for the 3-day skilled-nursing rule, read the Important Message from Medicare, and — if you disagree — call the Quality Improvement Organization the same day for a fast appeal. Medicare Advantage plans issue a separate Notice of Medicare Non-Coverage that triggers the same appeal right.

Your phone rings. Your mom fell. She's in the emergency room, then she's "admitted," then two days later a case manager is on the phone saying she is "medically ready for discharge" and they need the bed.

Most families do not know the rules governing that phone call until they are already on the wrong side of them. This guide walks through the six things that actually matter — observation status, the 3-day rule, the discharge notice, the appeal window, skilled nursing coverage, and Medicare Advantage denials.

What is the difference between inpatient and observation status on Medicare?

Inpatient status means Medicare Part A pays for the stay; observation status means the patient is technically an outpatient covered under Part B, and cost-sharing can be dramatically higher. The status is a coding decision by the doctor and utilization-review team — not the room — and it silently controls skilled nursing coverage after discharge. Two patients in identical beds can walk out with completely different bills.

Since 2015, hospitals have been required to give patients a written Medicare Outpatient Observation Notice (MOON) within 36 hours of starting observation care. It looks like a one-page form. Read it. If you see the word "observation," you are already on the wrong side of the most important rule below.

What to do: Ask the case manager directly, in writing if possible: "Is my mother inpatient or observation? If observation, when will she be converted to inpatient?" If they cannot or will not convert her, escalate to the attending physician and, if needed, the hospital's patient advocate.

What is the 3-day rule for Medicare skilled nursing?

Original Medicare will only cover a skilled nursing facility (SNF) stay after a qualifying inpatient hospital stay of at least 3 consecutive days — three midnights, not counting the day of discharge. Observation days do not count, which is how a parent can spend five nights in a hospital bed and still fail the rule. The rule is spelled out in CMS's official SNF 3-Day Rule Billing guide.

Here is where families get hurt: a parent transfers to a nursing home for rehab and gets a bill for the entire stay because the first three nights were coded as observation.

Original Medicare enforces this rule strictly. Medicare Advantage plans can waive the 3-day requirement, and many do — but not all, and the waiver has to be in the plan's benefits. If your parent is on Medicare Advantage, call the plan's number on the back of the card and ask, in these exact words: "Does this plan waive the 3-day inpatient requirement for skilled nursing coverage?"

How do I appeal a hospital discharge if I think it is too soon?

Call the Quality Improvement Organization (QIO) number listed on the Important Message from Medicare notice — the same day you disagree. Your parent stays in the hospital during the review, Medicare keeps paying until noon the day after the QIO's decision, and the appeal right disappears entirely once the discharge happens. It is the fastest appeal in Medicare.

Before a hospital discharges a Medicare patient, they must deliver an Important Message from Medicare (IM) — a two-page notice explaining the patient's right to a fast appeal. It should be given within two days of admission and again within two calendar days before discharge. In 2026, the two national QIOs handling appeals are Livanta and Kepro/Acentra Health; the phone number is printed on the notice.

If the QIO agrees with your family, the discharge is delayed and additional care is covered. You cannot appeal after the discharge has happened. The window is real and it is small.

What does Medicare actually cover after discharge?

Original Medicare Part A covers up to 100 days in a skilled nursing facility per benefit period — but only after a qualifying 3-day inpatient stay and only while the patient needs skilled care. Days 1–20 are fully covered, days 21–100 carry $217/day coinsurance in 2026, and custodial care is never covered at any point. Day 101 onward is 100% out of pocket (Medicare.gov SNF coverage).

Coverage requires skilled care — physical therapy, IV medications, wound care, or another service that requires a licensed professional. "Custodial care" — help with bathing, dressing, or eating — is not covered by Medicare, ever. This is the single most common family surprise: Medicare does not pay for a nursing home just because someone cannot live alone. The full 2026 cost-sharing figures are confirmed in the CMS 2026 Parts A & B premiums and deductibles fact sheet.

Home health is a separate benefit. Medicare Part A or Part B covers intermittent skilled nursing care and therapy at home, with no day limit, as long as your parent is homebound and needs skilled care ordered by a doctor. There is no coinsurance for the covered services themselves.

What if my parent is on Medicare Advantage instead of Original Medicare?

55% of eligible Medicare beneficiaries — 35.2 million people — are enrolled in Medicare Advantage in 2026 (KFF enrollment update), and the plan — not CMS — decides what is medically necessary. The plan can require prior authorization for skilled nursing, deny continued coverage mid-stay with a Notice of Medicare Non-Coverage (NOMNC), and waive or enforce the 3-day rule. The fast-appeal right still exists, exercised through the plan and the QIO.

If the plan denies coverage, your parent has the right to a fast appeal through the QIO — same process as Original Medicare — plus additional levels of internal plan appeal and, ultimately, an independent review. Do not wait. Get the denial in writing, call the number on the NOMNC the same day, and make sure you are on file with the plan as an authorized representative using Form CMS-1696. Without that form, the plan can legally refuse to talk to you.

What 6 questions should I ask the case manager in the first hour?

Print this list and run it in this exact order the moment the case manager calls. These six questions surface every issue that can cost a family thousands after discharge — status, midnights, destination, authorization, the discharge notice, and the appeal contact — and they take less than ten minutes to ask.

1. Is my mother inpatient or on observation? (If observation, when will she be converted?)
2. How many midnights has she been inpatient so far? (For the 3-day rule.)
3. Where are you discharging her to — home, home with home health, or skilled nursing?
4. Has the plan approved the SNF or home health placement? (Get the auth number.)
5. When was the Important Message from Medicare delivered, and can I have a copy?
6. Who is the QIO for this hospital and what is their appeal phone number?

If the case manager cannot answer any of these on the spot, ask to speak to the hospital's patient advocate or ombudsman.
