What happens when Medicare stops paying for rehab?

The two clocks that decide coverage

Two things have to be true for Medicare Part A to pay a skilled nursing facility bill, and they run on different clocks. The first is the benefit period: Part A limits skilled nursing facility coverage to 100 days in each benefit period, and a new benefit period starts after 60 days in a row without hospital or skilled care. The second is the skilled need itself, which is decided day by day. A stay can stop on day 9 or day 40 because the daily skilled care is no longer medically necessary, even though the 100-day clock has barely moved.

To start the clock at all, the person needs a qualifying inpatient hospital stay of at least 3 days in a row, counted from the day of admission as an inpatient and not including the day of discharge. Time spent in the emergency room or under observation does not count toward those 3 days, even overnight. Medicare Advantage plans may waive the 3-day rule, and some doctors in an approved Accountable Care Organization can use a skilled nursing facility 3-day rule waiver, so it is worth asking the hospital directly whether the stay will qualify. Read the coverage rules alongside the Medicare nursing home coverage guide if you want the same conditions in full.

Why a stay often ends before day 100

The single most common reason Medicare stops paying is that the care a person needs has changed from skilled care to custodial care. Medicare.gov defines skilled care as nursing and therapy care that can only be safely and effectively performed by, or under the supervision of, professionals or technical personnel. Custodial care is help with everyday activities such as bathing, dressing and eating. Part A does not cover custodial care when that is the only care needed, and that is the kind of care most long-term residents of a nursing home receive.

In plain terms, once the wound care, the injections, the IV therapy or the physical therapy stops, the reason Part A was paying goes away with it. The resident still needs a place to live and help with daily life, but that is not what Part A covers. This is the moment the bill moves to one of the four payers below, and it is worth knowing which one applies before the coverage end date, not after.

Getting better is not the only test

Families are often told a stay is ending because the person has plateaued, meaning the condition is not improving. That framing is worth pushing back on. Medicare.gov states that a person needs skilled nursing care or therapy to improve or maintain the current condition, or to prevent or delay it from getting worse. Maintaining a condition is on the list, so a skilled need can continue without visible improvement, and a maintain or slow-decline plan is still skilled care.

If a facility says the stay is ending because the person is not improving, ask for the specific reason in writing and for the notice described below. A decision that rests only on the absence of improvement is exactly the kind of decision the appeal route is built for.

What you pay in 2026

For each benefit period in 2026, the Medicare.gov cost sharing runs like this. Days 1 to 20: you pay $0 each day after the $1,736 Part A deductible, and you do not pay that deductible twice if it was already paid for a hospital stay in the same benefit period. Days 21 to 100: you pay $217 each day. Days 101 and beyond: you pay all costs. If the person is in a Medicare Advantage plan, the plan may charge a copayment during the first 20 days, so check the plan documents.

The daily coinsurance is the small number next to the real one. For scale, the 2025 national median this site tracks puts a semi-private nursing home room at about $9,581 a month. Compare that with the daily coinsurance on days 21 to 100, and you can see how quickly private pay takes over once Part A stops. The nursing home cost breakdown and the care cost calculator put a local number on it.

Four ways to pay after Medicare stops

When Part A ends, the bill does not disappear, it changes hands. These are the four routes most families use, usually in some combination.

1. 1Medicaid, if the person qualifies. Medicaid is the largest payer of long-term nursing home care in the country, but it is a means-tested program run by each state, and it has income and asset limits plus a look-back period on past transfers. It also requires a level-of-care assessment. Start the application before the money runs out rather than after.
2. 2Long-term care insurance, if a policy is in force. An in-force long-term care policy can pay after Medicare stops, usually once the person cannot do a set number of daily activities or has a cognitive impairment. Check the policy for the elimination period (how many days you pay first), the daily or monthly benefit, and whether it pays for the setting you want.
3. 3Private pay, out of income, savings, or a home. Most families pay part of the bill themselves. The size of that bill is the reason to get the written fee schedule before a move, not after, because therapies, medications and add-on services sit on top of the monthly rate.
4. 4Veterans benefits and home care. Veterans may qualify for VA benefits that help pay for care, and some families move the person home with home health or a private aide instead of staying in a facility. Home care is not automatically cheaper, so compare the hours and the hourly rate against the facility rate before assuming it.

Which one applies depends on the person. Read the Medicaid nursing home rules and the long-term care insurance coverage guide before you count on either, because both have conditions that decide whether they pay. If home care is the plan instead, the home care versus nursing home comparison shows where the break-even point sits.

If you think the decision is wrong

There is a defined appeal path, and it is fast. When a facility plans to end covered services or discharge a resident from skilled care, it has to give a written notice before the coverage end date. The notice names the date coverage ends and the reason, and it is called a Notice of Medicare Non-Coverage. It opens the right to a fast, or expedited, appeal to the Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO) that handles Medicare appeals in your state.

Two timing points decide whether the appeal can protect the bill. Ask for the notice as soon as you are told the stay is ending, and file the appeal before the coverage end date on the notice. If the appeal succeeds, coverage generally continues while it is reviewed; if you wait until after the end date, the person may owe for the days in between. The fast-appeals process is described on Medicare.gov in the claims and appeals section.

Where these rules come from

Every coverage rule and figure on this page was read from Medicare.gov. The 100-day benefit period limit, the 2026 cost sharing of $0 for days 1 to 20 after the $1,736 Part A deductible, $217 per day for days 21 to 100 and all costs from day 101, the 3-day qualifying inpatient hospital stay, the observation rule, the definition of skilled versus custodial care, and the improve-or-maintain coverage standard all come from the Medicare.gov page on skilled nursing facility care. The notice and the expedited appeal to the BFCC-QIO come from the fast-appeals guidance on Medicare.gov. Care costs are the 2025 national medians from the cost survey named above, attributed next to the figure. Medicaid, long-term care insurance and veterans rules are set by each program and, for Medicaid, by each state, so verify them against the state where care is given. This is not medical, legal or financial advice for an individual decision.
