How Long Medicare Pays for a Nursing Home After a Hospital Stay

The call usually comes on a Thursday. Dad went into the hospital with pneumonia or a broken hip, he is being discharged to a nursing home for rehab, and the family wants to know how long Medicare will pay before the bills start. I have sat in that chair with my own mother, and I know the question underneath it: how much time do we have to figure out what comes next?

The short answer is that Medicare can pay for up to 100 days in a skilled nursing facility per benefit period, and most people get far fewer than 100. The first 20 days are generally covered in full, days 21 through 100 carry a daily copay, and coverage can end before day 100 the moment the person no longer needs daily skilled care. Those are the general rules; confirm the current ones with Medicare or the facility’s business office. What follows is how they play out for Long Island families and what to do with the time.

The short answer: up to 100 days, usually far fewer

Medicare’s skilled nursing facility benefit is a rehabilitation benefit, not a residence benefit. It exists to get a person back on their feet after a hospital stay, and it ends when the medical reason ends or when the clock runs out, whichever comes first. The 100 day number is a ceiling, not a promise. In practice, many Long Island families see coverage end somewhere between two and six weeks because the rehab goals are met or the therapy team decides skilled care is no longer required.

That matters because the day coverage ends, the family faces a choice: pay the nursing home privately for a long term bed, apply for Medicaid, move home with help, or move to assisted living or memory care. My senior housing on Long Island guide lays out those options side by side, and I would rather you read it in week one than on the day of the cutoff notice.

The conditions that have to line up before Medicare pays a single day

Before the 100 day count even begins, a set of conditions has to be met. These are general rules and the details change, so confirm the current version, but the structure has held for a long time.

1. A qualifying hospital stay of at least three consecutive days as an admitted inpatient. The discharge day does not count, and days under observation status do not count.
2. Admission to the skilled nursing facility within a short window after leaving the hospital, generally 30 days.
3. A doctor’s order for daily skilled care, meaning nursing or therapy that requires a licensed professional, related to the hospital condition or something that arose during treatment.
4. A Medicare certified facility. Most nursing homes on Long Island are, but the bed itself must be in the certified part of the building.
5. Days remaining in the current benefit period, which I explain below.

The observation trap deserves its own warning. A parent can sleep three nights in a hospital room and still be classified as outpatient under observation. If so, condition one fails and Medicare pays nothing toward the rehab stay. Ask the nurse every day whether your parent is admitted or under observation, and ask for the answer in writing.

What the 100 days look like on the bill

Once the conditions are met, the benefit runs in three bands. I do not quote the copay because it changes every year; the facility’s business office will have the current figure.

Days in the benefit period	Who pays	What families should know
Days 1 through 20	Medicare pays the full approved amount for the room, meals, nursing and therapy	Private room upgrades and personal items may still be billed
Days 21 through 100	Medicare pays most of it; the person owes a daily copay	Many Medigap policies and some Medicare Advantage plans cover the copay; check the plan
Day 101 and beyond	Medicare pays nothing	The family pays the long term daily rate, applies for Medicaid, or moves the person to another setting

Two things about the table. First, the daily copay from day 21 adds up quickly over several weeks, and a family that did not know it was coming can get a surprising bill in week four. Second, a person who is discharged home on day 35 and readmitted to the hospital a week later may be able to use the remaining days of the same benefit period for a second rehab stay, which is a detail worth asking about.

Why coverage usually ends before day 100

Medicare keeps paying only while the person needs daily skilled care. When the therapy team documents that the goals have been met, or that the person has reached a plateau and no longer requires a skilled professional, the facility issues a notice that Medicare coverage is ending. From that date forward, the stay is custodial, and custodial care is not covered no matter how many days remain on the calendar. I explain that line in does Medicare cover long term care.

Families often hear that coverage ends because the person is not improving. As a general rule, Medicare coverage does not require improvement; it requires a continuing need for skilled care, which can include maintaining function or preventing decline when a skilled professional is needed to do it. If you believe the cutoff is premature, the notice includes a way to request a fast appeal. Confirm the current appeal steps with the facility and the notice itself, and act quickly, because the window is short.

What I see in practice is that the cutoff is rarely a surprise to the staff. Ask the therapy team in the first week what the goals are and roughly how long they expect to work toward them. That answer is your planning calendar.

What a benefit period is, and when the 100 days reset

Medicare counts skilled nursing days per benefit period, not per year and not per lifetime. A benefit period begins on the day of a hospital admission and ends after the person has gone 60 consecutive days without inpatient hospital care or skilled care in a facility. After those 60 days, a new benefit period starts and a new set of 100 days becomes available, provided the person has another qualifying hospital stay.

So a parent who used 40 days of rehab in March, went home, stayed out of the hospital through the summer, and is readmitted in September will start a fresh 100 day count. A parent who stays in the nursing home as a long term private pay resident does not reset the clock, because the days of facility care keep the benefit period open. Confirm the current rules for your parent’s exact situation, since the counting can get complicated when there are several short admissions.

Medicare Advantage, Medigap, and the notices to read

If your parent is on a Medicare Advantage plan, the same benefit exists but the plan runs it. Some plans waive the three day hospital rule; many require prior authorization for the admission and then for each additional stretch of days, and they may review more often than Original Medicare. The practical effect is that the cutoff can come sooner and with less warning. Ask the facility’s business office which plan your parent has and how that plan handles rehab reviews.

Medigap supplements can cover the daily copay from day 21 through 100 for people on Original Medicare, which removes the biggest out of pocket piece of a covered stay. They do not extend the stay. Whichever coverage applies, read every notice the facility hands you. The notice that says coverage is ending is also the notice that starts the appeal clock, and families who leave it on the nightstand lose the chance to challenge it.

Day 101 on Long Island: the choice families face

When Medicare stops, a nursing home will offer a long term bed at its private daily rate, and the business office will often mention Medicaid in the same breath. Before you accept either, step back and ask whether a nursing home is the right setting at all. A person who finished rehab and needs help with bathing, dressing, meals and medications, but does not need a nurse at the bedside around the clock, is usually a fit for assisted living, and a person with dementia who is physically stable is usually a fit for memory care. I lay out that line in assisted living vs skilled nursing and in skilled nursing facility vs nursing home.

The money works differently in each setting. Medicaid is the main payer for long term nursing home stays, while assisted living and memory care on Long Island are mostly paid privately, with long term care insurance and veterans benefits where they apply. I compare the structures without quoting figures in what a nursing home costs on Long Island vs assisted living; ask me for current numbers. I have toured more than 90 communities across Nassau, Suffolk and Queens, and the best use of a rehab stay is to tour two or three of them while your parent is still covered, so that day 101 is a planned move and not a scramble.

Use the rehab days to plan, not to wait

Assisted Living Locators of Long Island helps families across Nassau, Suffolk and Queens turn a rehab cutoff into a calm next step, whether that is assisted living, memory care or independent living. The help is free to families; communities compensate the advisor when a family moves in. I plan 18 to 24 months past the move so a rising level of care is already in the budget.

My office is at 42 Prospect Ave, Glen Cove, NY 11542. Call me during the rehab stay and we will use the days well.
