Medicare Skilled Nursing Coverage: What the 100 Days Really Mean for Buffalo Families

Families often hear that Medicare pays for 100 days in a nursing home. It does not work that way. Here is what the benefit actually covers, where the money stops, and how to push back if coverage is cut off early.

The 100-Day Myth

If your mother has just had a fall or a stroke at a Buffalo-area hospital, someone has probably told you that Medicare covers 100 days of nursing home care. That sentence is both true and badly misleading. Medicare does cover up to 100 days of skilled nursing facility (SNF) care in a benefit period, but only if a specific set of conditions is met, and the cost to your family changes on day 21. Most families who run into trouble are not surprised by the 100-day cap. They are surprised by how much sooner coverage can end, and how much it can cost before then.

This guide explains the benefit in plain language for Erie and Niagara County families. It covers Original Medicare. Medicare Advantage plans have to cover the same skilled nursing services but can apply their own rules, which we explain below. Figures are from the federal government’s 2026 Medicare announcements and change every January, so confirm current amounts at medicare.gov. This is general information, not legal or financial advice.

Condition One: A Qualifying Inpatient Stay

Original Medicare pays for skilled nursing only after a hospital stay of at least three consecutive days as a formally admitted inpatient. The day of discharge does not count. The most common trap is observation status: a patient can spend two or three nights in a hospital bed and still be classified as an outpatient receiving observation services, which does not count toward the three days. We cover this in detail in our guide to observation status versus inpatient admission. The practical advice is to ask the hospital case manager, on day one, whether your parent is admitted as an inpatient or under observation, and to write down the answer and who gave it.

The patient must also enter a Medicare-certified skilled nursing facility within 30 days of leaving the hospital, generally for a condition treated during the hospital stay. A person who goes home for six weeks and then needs rehabilitation will usually not qualify under this rule.

Condition Two: A Daily Skilled Need

Medicare covers skilled care, not custodial care. Skilled care means services that can only be safely provided by or under the supervision of nurses or therapists: physical, occupational, or speech therapy after a hip fracture or stroke, wound care, IV medications, or complex monitoring. Help with bathing, dressing, eating, and supervision is custodial care, and Medicare does not pay for it by itself. A doctor must certify that the person needs skilled care on a daily basis, and the facility must be Medicare-certified. You can look up a facility’s certification and quality data through CMS Care Compare, and check its state inspection record using our inspection-history walkthrough.

What the 100 Days Cost

For each benefit period, Original Medicare pays as follows:

Days 1 through 20: Medicare pays the full approved cost, with no coinsurance for the family, provided the conditions above are met.

Days 21 through 100: The family owes a daily coinsurance. The federal figure for 2026 is $217.00 per day, which works out to roughly $6,500 for a thirty-day stretch. Medicare pays the rest of the approved cost.

Day 101 and beyond: Medicare pays nothing, and the family is responsible for the full cost.

Many people have a Medigap (Medicare Supplement) policy, and most standardized Medigap plans, with the exception of Plan A, cover the days 21 through 100 coinsurance. Retiree coverage from a former employer, such as a union or public-sector plan, may also help. Check the actual policy rather than relying on memory, because the benefit depends on the plan letter and the insurer.

A benefit period begins when the patient is admitted as an inpatient and ends after 60 days in a row without inpatient hospital or skilled nursing care. A new qualifying hospital stay after that point starts a fresh benefit period with a fresh set of 100 days. Here is the part many families miss: you rarely use all 100 days. Medicare covers skilled care only as long as the person still needs it, so the real limit is usually the clinical team’s judgment, not the calendar.

A Hypothetical Family

Consider a fictional example. Margaret, 82, lives alone in Cheektowaga. She falls and fractures her hip and is admitted to a Buffalo hospital as an inpatient for four days. Her son confirms the admission status in writing, and she transfers to a Medicare-certified rehabilitation unit within a week. For the first 20 days, Medicare pays. On day 21 the daily coinsurance begins, which would be covered if Margaret has a Medigap plan and would otherwise come out of her family’s pocket. On day 34 the therapy team writes that she is walking with a walker and can manage safely at home with help. Medicare coverage ends there, even though she has used only about a third of her 100 days, and the question becomes what support she needs at home, which is where Buffalo options such as consumer-directed personal assistance, home care agencies, and adult day programs come in.

If Coverage Ends Too Soon

Facilities must give a written Notice of Medicare Non-Coverage when they plan to end covered services, generally at least two days before the last covered day. This is the moment families should not sit on. The notice explains how to request a fast appeal from the Medicare quality improvement organization (QIO) named on the form, and the deadline is tight, typically by noon of the day before coverage ends. Call the number printed on the notice itself; we have not verified the current QIO contractor for New York in this guide, and contractors change. While a fast appeal is pending, you generally are not required to pay for the covered services during that review.

Two points strengthen an appeal. First, under the Jimmo v. Sebelius settlement, Medicare coverage turns on whether the person needs skilled care to maintain their condition or slow decline, not on whether they are still improving. A plateau in therapy is not, by itself, a reason to stop coverage. Second, ask the therapists and nurses to document why skilled care is still needed. The New York State Health Insurance Information, Counseling and Assistance Program (HIICAP), run through the Office for the Aging, can help you with Medicare appeals, and Erie County’s NY Connects line at (716) 858-8526 can point you to local help. Separately, if a nursing home tries to discharge a resident for non-payment or other reasons, see our guide to involuntary discharge appeals.

Medicare Advantage Plans Work Differently

If your parent has a Medicare Advantage plan, the plan must cover the same skilled nursing services as Original Medicare, but it can require prior authorization, limit you to a network of facilities, and set its own daily copayments after the first days. Some plans waive the three-day inpatient requirement and some do not. The mechanics of the fast appeal are broadly similar, but the plan is making the coverage decision, so request the plan’s written denial and ask how to appeal. Before agreeing to a transfer, call the plan or ask the hospital case manager to confirm that the specific facility is in network and that authorization has been approved.

Planning for Day 101, or Sooner

The most useful time to plan for the end of Medicare coverage is the first week of the stay, not the last. Ask the facility’s social worker for a realistic estimate of how long skilled care is likely to last and what your parent will need afterward. If the answer is long-term care, the options are paying privately, long-term care insurance, or New York Medicaid. Our spend-down walkthrough and managed long term care guide show how those pathways work for a hypothetical family. Medicaid financial rules are technical and change annually, so an elder law attorney is worth a consultation before assets are moved, since transfers can trigger a penalty period.

Questions to Ask Before You Sign Anything

At admission, ask the facility these questions and write down the answers. Is my parent classified as an inpatient or under observation, and what is the date of admission? Is the facility Medicare-certified, and is it in my parent’s plan network? Who decides when skilled care is no longer needed, and how will we be told? What will the daily coinsurance be, and does my supplemental coverage pay it? Be careful with any admission paperwork that asks a family member to sign as personally responsible for payment; a representative signing for a resident is not the same as guaranteeing payment, and you should read before you sign.
