Medicare's 100 Days of Rehab: What Central Ohio Families Should Actually Expect
Almost every family arrives at rehab believing they have a hundred covered days. Almost none of them get a hundred days — and the reasons why are decided in the hospital, days before anyone mentions rehab at all.
The Number Everybody Repeats
A daughter in Grove City calls two days after her mother's hip surgery. The hospital has told her Mom is going to a skilled nursing facility for rehab, someone used the phrase "Medicare covers a hundred days," and she has built her entire month around that sentence. She has told her employer she will not need leave until October. She has told her brother in Cincinnati there is no rush to come up.
Nineteen days later she calls back, furious and frightened, because the facility has just handed her a form saying coverage ends Friday.
Nothing improper happened. The hundred-day figure is real — it is the outer limit of Medicare's skilled nursing facility benefit within a single benefit period — but it functions the way a speed limit does, not the way a bank balance does. It describes a ceiling, not a deposit. What actually determines how many days a parent in Westerville or Newark or Circleville gets is a chain of technical conditions that begins before the ambulance even leaves the driveway, and almost none of it gets explained to families in the moment it matters.
Here is the chain, in the order a central Ohio family will hit it.
The Qualifying Stay: Three Midnights, and the Word "Inpatient"
Under Traditional Medicare, the skilled nursing facility benefit generally requires a qualifying inpatient hospital stay of three consecutive midnights, not counting the day of discharge. That is the first gate, and it is the one families lose most often — not because the parent went home too early, but because the hospital never classified the stay as inpatient in the first place.
Hospitals can hold a patient under outpatient observation status. The bed looks the same. The wristband looks the same. The meals, the monitors, the overnight nurses all look the same. But for Medicare's purposes those nights are outpatient care, and outpatient nights do not count toward the three-midnight requirement. A parent can spend four nights at a hospital in Franklin or Fairfield County and still walk out ineligible for a covered rehab stay.
Federal law requires a hospital to give any patient who has been in observation for more than 24 hours a written Medicare Outpatient Observation Notice — the MOON — and to explain it out loud. In practice it is handed over during a shift change, in a folder, to a family that has been awake for thirty hours. If you take one operational habit away from this article, take this one: on the first morning, ask the nurse or case manager the exact question "Is my mother admitted as an inpatient, or is she under observation?", write the answer and the time in a notebook, and ask it again every single morning. Status can change. Nobody will chase you down to tell you it did.
Medicare Advantage plans work differently, and we come back to that below.
What "Skilled" Means, and the Improvement Myth
Passing through the hospital gate only starts the clock. Coverage continues day to day only while the facility is delivering care that genuinely requires the skill of licensed nursing or therapy staff — wound care, IV therapy, complex medication management, physical or occupational therapy that a family member could not simply be taught to do.
When that skilled need resolves, coverage ends, even if the person is still frail, still unsteady, still not remotely ready to live alone. This is the single hardest thing for families to absorb, and it is why the median central Ohio rehab stay lands somewhere in the two-to-five-week range rather than at day 100. Medicare's rehab benefit is not a bridge to permanent placement. It was never designed to be one.
There is one widespread misconception worth naming flatly, because it costs families real days. Coverage does not require continued improvement. The settlement in Jimmo v. Sebelius established that skilled care may be covered when it is needed to maintain a person's condition or to slow decline, and CMS has issued guidance confirming it. Yet families across the country — including plenty in this region — are still told some version of "she's plateaued, so Medicare won't pay." That sentence is not a coverage rule. It is grounds to ask for the determination in writing and to appeal.
The Money, Plainly
Under Traditional Medicare in 2026, a covered skilled nursing facility stay breaks down like this within a benefit period: days 1 through 20 carry no coinsurance at all; days 21 through 100 carry a daily coinsurance of $217.00; and past day 100, Medicare pays nothing toward skilled nursing facility care.
That day-21 cliff is worth doing arithmetic on before it arrives. Thirty days of coinsurance is more than $6,500 out of pocket. A Medicare Supplement (Medigap) policy commonly covers that coinsurance in full, which is exactly the kind of thing families discover they have — or don't — at the worst possible moment. Check the supplement now, not on day 19.
A benefit period, incidentally, is not a calendar year. It begins with an inpatient admission and ends after 60 consecutive days without inpatient or skilled care. A parent who is readmitted six weeks after discharge is usually still inside the same benefit period, with the same used-up days. A parent readmitted four months later typically starts fresh.
Medicare Advantage Changes the Choreography
Roughly half of Ohio's Medicare population is enrolled in a Medicare Advantage plan, and if your parent is, several things above shift.
Many Advantage plans waive the three-midnight requirement, which is a genuine advantage. In exchange, most require prior authorization before a rehab admission and conduct ongoing concurrent review, meaning a plan reviewer — not the treating therapist — is deciding week by week whether the stay continues. Cost-sharing is set by the plan, and daily copays frequently begin far earlier than day 21. Networks matter too: the facility three minutes from your parent's house in Pickerington may be out of network for their specific plan.
Advantage plans are required to follow Traditional Medicare's coverage criteria when deciding whether skilled care is covered; they cannot invent a stricter standard. They also have their own appeal process, with fast-track timelines. Ask the plan for the coverage determination in writing every time it changes.
The Notice That Ends It — and the Free Appeal Most Families Skip
When the facility intends to stop billing Medicare, it must give the beneficiary a Notice of Medicare Non-Coverage, generally at least two calendar days before the last covered day. It is a plain form. It arrives quietly. Most families read it as a bill, sign it, and start packing.
It is not a bill. It is an appeal form. Printed on it is the phone number for the regional Beneficiary and Family Centered Care Quality Improvement Organization — for Ohio, that is Commence Health, the organization formerly known as Livanta. Calling by the deadline on the notice triggers an independent medical review, usually decided within roughly a day, and while the review is pending the family is generally not on the hook for the extra days. The appeal costs nothing.
Appeals do not always win. But they are decided by someone outside the facility, on the medical record, and a meaningful share of them buy additional covered days. If the coverage-ending explanation you were given was "she's not improving," appeal.

Choosing the Facility: Twenty Minutes of Homework
Discharge planners typically hand families a printed list of facilities with available beds and, appropriately, decline to recommend one. That list is not a quality ranking. It is a bed-availability report.
Two public sources let you do real diligence in the time it takes to drink a coffee. Ohio's own Long-Term Care Consumer Guide, published by the Ohio Department of Aging, compares nursing homes and residential care facilities statewide on recent inspection results, resident and family satisfaction survey results, and facility-reported services. Federal Care Compare, from CMS, adds staffing levels, quality measures and inspection history for Medicare-certified facilities. Read the deficiency narratives, not just the star count, and look for whether a problem repeated across survey cycles or appeared once and was corrected.
Then ask each candidate three questions by phone: how many days a week does therapy actually run, including weekends; who on staff handles Medicare coverage questions and appeals; and what happens if my parent is still here when Medicare stops paying.
Plan the Exit on Day Three, Not Day Nineteen
The families who come through a rehab stay intact are the ones who treat the admission as the beginning of a discharge plan rather than a pause. By the end of the first week, someone should know the answer to: is the realistic destination home with help, assisted living, or long-term nursing care? What does each cost, and who pays? Is the house workable — bathroom, stairs, entry?
If the destination might be long-term care paid with public benefits, start reading about Ohio's programs immediately, because eligibility work takes far longer than a rehab stay does.
Rehab in central Ohio is a genuinely good benefit, used well. It restores a great many people to their own kitchens. What it is not is a hundred-day cushion, and the families who understand that on day three — while there is still time to tour a community in Delaware County, interview a home care agency in Reynoldsburg, or get a supplement policy verified — are the ones who never have to make the furious phone call on day nineteen.
Frequently Asked Questions
Does Medicare really pay for 100 days of nursing home care after a hospital stay?
One hundred days is the maximum length of the skilled nursing facility benefit in a single benefit period, not a promise or an entitlement. Coverage continues only while a Medicare-certified facility is delivering care that requires the skill of licensed nursing or therapy staff and the beneficiary meets the other conditions, including a qualifying inpatient hospital stay. In practice most central Ohio families see coverage end well before day 100, often somewhere between two and five weeks, because the skilled need resolves. Families who plan a discharge around the number 100 are almost always planning around a date that will not arrive.
What is observation status, and why does it matter for rehab coverage in Ohio?
A hospital can keep a patient overnight, sometimes for several nights, while classifying the stay as outpatient observation rather than inpatient admission. Traditional Medicare's skilled nursing facility benefit generally requires a qualifying inpatient hospital stay of three consecutive midnights, and observation nights do not count toward it. A patient can therefore spend four nights in a bed at a central Ohio hospital and still not qualify. Federal law requires hospitals to give patients who have been in observation for more than 24 hours a written Medicare Outpatient Observation Notice, usually called the MOON, and to explain it verbally. Ask about status on day one, ask again each morning, and get the answer in writing.
What does Medicare rehab cost out of pocket in 2026?
Under Traditional Medicare in 2026, days 1 through 20 of a covered skilled nursing facility stay in a benefit period carry no coinsurance, and days 21 through 100 carry a daily coinsurance of $217.00 set by the Centers for Medicare and Medicaid Services. Beyond day 100 in a benefit period Medicare pays nothing for skilled nursing facility care. A Medicare Supplement policy may cover the day-21 coinsurance, and Medicare Advantage plans set their own cost-sharing schedules, which frequently begin charging a daily copay much earlier than day 21. Verify the actual figures in the plan's own summary of benefits rather than assuming the Traditional Medicare numbers apply.
Can Medicare stop paying for rehab because my parent has stopped improving?
No. Coverage does not depend on a beneficiary showing continued improvement. The settlement in Jimmo v. Sebelius confirmed that skilled care can be covered when it is needed to maintain a person's condition or to prevent or slow deterioration, and the Centers for Medicare and Medicaid Services has issued clarifying guidance to that effect. Despite this, an improvement standard is still cited informally by staff in facilities across the country. If a family in Franklin, Delaware or Licking County is told coverage is ending because a parent has plateaued, that phrasing alone is grounds to ask for the decision in writing and to file the expedited appeal described on the notice.
How do I appeal when the rehab facility says Medicare coverage is ending?
The facility must give the beneficiary a Notice of Medicare Non-Coverage, generally at least two calendar days before coverage ends. That notice contains the phone number of the Beneficiary and Family Centered Care Quality Improvement Organization for the region, which for Ohio is Commence Health, formerly known as Livanta. Calling by the deadline printed on the notice triggers a fast, independent medical review, usually decided within about a day, and the family is typically not responsible for the cost of the additional days while that review is pending. The appeal is free. Most families never use it because nobody explains that the notice is an appeal form rather than a bill.
How can I check the record of a rehab or nursing facility in central Ohio before agreeing to it?
Two public sources are worth twenty minutes. Ohio's own Long-Term Care Consumer Guide, published by the Ohio Department of Aging, lets you compare nursing homes and residential care facilities across the state on recent inspection results, resident and family satisfaction survey results, services and other facility-reported detail. Federal Care Compare, run by the Centers for Medicare and Medicaid Services, adds staffing data, quality measures and inspection history for Medicare-certified facilities. Read the actual survey deficiency narratives rather than only the star rating, and pay attention to whether a problem was isolated or repeated across survey cycles.
