    U.S. Seniors: 100 Days and the $217 Coinsurance for Skilled Nursing

    U.S. Seniors: 100 Days and the $217 Coinsurance for Skilled Nursing

    Yes, Original Medicare Part A pays for short-term skilled nursing facility care, but only after a qualifying hospital stay, and only for a limited window. Coverage runs $0 for days 1 through 20 of each benefit period, then a $217 daily coinsurance from day 21 through 100 in 2026. After that, you pay the full cost. Medicare does not cover long-term custodial nursing home care.

    TL;DR:

    • Medicare only covers skilled nursing care after a three-day inpatient hospital stay, and coverage is limited to 20 days at no cost, then 217 dollars daily from days 21 to 100.
    • Qualification for Medicare skilled nursing coverage requires a recent inpatient hospital stay, admission to a Medicare-certified facility within 30 days, and a documented need for daily skilled care.
    • Benefit periods restart after 60 consecutive days without inpatient care, meaning multiple 100-day coverage spans can occur within a year if the patient remains out of the hospital.
    • Medicare Advantage plans may waive the three-day hospital stay requirement and have different network or authorization rules, which requires careful plan review.
    • Long-term custodial nursing home care is not covered by Medicare after the skilled care period ends; Medicaid typically covers long-term care for those who qualify financially.

    What Skilled Nursing Coverage Under Medicare Actually Pays For

    Skilled nursing care means services that require a licensed nurse or therapist: physical therapy after a hip replacement, wound care that needs sterile technique, IV antibiotics, or swallowing therapy after a stroke. It’s ordered by a physician and delivered under a plan of care. This is the distinction that trips up most families: skilled nursing coverage under Medicare has nothing to do with how frail someone is or whether they can live alone. It’s about whether they need clinical treatment from trained staff every day, not just help getting dressed.

    The day-by-day cost structure for Medicare Part A in 2026 looks like this:

    Days in benefit period What you pay
    Days 1–20 $0
    Days 21–100 $217 per day (coinsurance)
    Day 101 and beyond 100% of costs

    The coinsurance hit is real money. At $217 a day, a 30 day stretch of coinsurance runs into substantial out-of-pocket costs, which is exactly why so many discharge decisions get made around day 20. Facilities and families both watch that date closely, and the MedPAC report to Congress documents a measurable spike in discharges right around that threshold. Whether that timing lines up with what’s clinically right for the patient is a separate question worth asking your care team directly.

    Who Qualifies for Skilled Nursing Facility Medicare Coverage?

    Three conditions have to be met before Medicare pays a dime toward skilled nursing facility care. Miss any one of them and you’re looking at a denial, no matter how medically necessary the care is.

    • A 3-day inpatient hospital stay. You need three consecutive days as an admitted inpatient. Time spent under “observation status” does not count, even if you’re in a hospital bed for a week. This single rule causes more coverage denials than almost anything else in the Medicare rulebook.
    • Admission to a Medicare-certified SNF within 30 days of hospital discharge. Wait longer than that without a documented medical reason, and the window closes.
    • A documented need for daily skilled care. In Medicare’s terms, that means skilled nursing 7 days a week or skilled therapy at least 5 days a week, not occasional check-ins.

    Pro Tip: Ask the hospital case manager, in writing, whether your loved one was classified as “inpatient” or “under observation.” That one word on the discharge paperwork determines whether Medicare pays a cent toward the skilled nursing facility that follows.

    How Do Medicare Benefit Periods Affect Your 100 Days?

    The “100 days” figure gets thrown around like a fixed annual allowance. It isn’t. Medicare measures coverage in benefit periods, and understanding how those start and stop changes how you plan.

    1. A benefit period begins the day you’re admitted as an inpatient to a hospital or SNF.
    2. It ends after 60 consecutive days with no inpatient hospital or SNF care. Get readmitted on day 61 or later, and a brand new benefit period starts, with a fresh set of up to 100 SNF days and a new Part A deductible.
    3. Exhaust your 100 days within a single benefit period, and Part A stops paying for that spell entirely. You can appeal a coverage decision, but you cannot simply “renew” days inside the same benefit period. A new one only opens after that 60-day break in inpatient care.

    This is why someone can hit “day 100” in March and still have full coverage available again in August, if their health stabilized and they stayed out of the hospital long enough in between.

    Does Medicare Advantage Cover Skilled Nursing Differently?

    Original Medicare enforces the 3-day inpatient rule without exception. Medicare Advantage plans don’t always play by the same book.

    • Many MA plans waive the 3-day hospital stay requirement entirely, sometimes approving direct SNF admission when a physician documents the need.
    • MA plans also run their own provider networks. A skilled nursing facility that’s fully Medicare-certified may still be out of network for your specific MA plan, which changes your costs even when the care itself is covered.
    • Some MA plans require prior authorization before SNF admission, something Original Medicare does not impose.

    The only way to know your plan’s actual rules is to check the Evidence of Coverage document or call your plan’s member services line directly. If you’re weighing Medicare Advantage against a Medigap policy in the first place, it’s worth reviewing how Medicare Advantage compares to Medicare Supplement plans in Florida before a hospitalization forces the decision on you.

    How Do You Confirm Skilled Nursing Coverage Before Admission?

    Don’t wait for a bill to find out whether coverage applied. Work through this before or during the SNF stay.

    1. Call the hospital discharge planner and get written confirmation of inpatient status and total hospital days.
    2. Call the SNF’s admissions or billing office and ask them to confirm Medicare certification and verify your specific coverage days in writing.
    3. Call your plan (Original Medicare or your MA carrier) or 1-800-MEDICARE to confirm benefit period status and remaining days.
    4. Collect documentation: inpatient admission notes, physician orders for skilled care, the SNF’s plan of care, and every billing statement that comes through.

    Pro Tip: If a facility suggests care may not qualify, ask for an Advance Beneficiary Notice (ABN) in writing before you agree to move forward. It documents the risk and preserves your right to appeal a denial rather than getting surprised by a bill after the fact.

    What Happens When Medicare Stops Paying for Nursing Home Care?

    Once Part A days run out, or once care shifts from skilled to custodial, Medicare exits the picture entirely. Medicare does not cover long-term custodial nursing home care when that’s the only type of care someone needs. A few paths remain.

    • Medicaid pays for the majority of long-term nursing home care nationally, but eligibility and asset rules vary significantly by state, and some states even cover Medicare SNF copays for dually eligible beneficiaries beyond day 20. An early call to your state Medicaid office is worth making before you need it.
    • Private long-term care insurance can cover custodial and skilled care, but check the elimination period (a waiting window before benefits start) and exactly which settings and benefit triggers the policy recognizes.
    • Private pay works until it doesn’t. Facilities can and do initiate discharge for nonpayment, so knowing your runway matters as much as knowing your coverage.
    • Hospital indemnity coverage can act as a stopgap that offsets some out-of-pocket costs tied to a hospital stay, though it’s not a substitute for long-term care planning.

    FAQ

    How long will Medicare pay 100% of a skilled nursing facility?

    Medicare covers skilled nursing facility care at $0 cost to you for the first 20 days of a benefit period. Starting day 21, a daily coinsurance applies.

    For how many days does Medicare pay 100% of skilled nursing facility costs?

    Exactly 20 days per benefit period. After day 20, you owe coinsurance according to Medicare Part A rules, which changed to $217 per day in 2026, through day 100, then the full cost after that.

    How much skilled nursing care will Medicare pay for overall?

    Medicare Part A covers up to 100 days of skilled nursing care per benefit period, with cost sharing kicking in after day 20 and full beneficiary responsibility after day 100. A new benefit period, and a fresh 100-day allowance, can open after a 60-day break from inpatient care.

    What happens if an elderly person can’t afford a nursing home once Medicare stops paying?

    Medicaid covers most long-term nursing home care once Medicare and personal funds are exhausted, though income and asset rules vary by state. Long-term care insurance and hospital indemnity coverage can also help bridge the gap, and speaking with a Medicare agent about your specific situation is worth doing well before you need the answer.

    Does Medicare Advantage cover skilled nursing facilities the same way as Original Medicare?

    Not always. Many Medicare Advantage plans waive the 3-day inpatient hospital rule that Original Medicare requires, but they often add network restrictions and prior authorization steps instead, so checking your plan’s Evidence of Coverage is essential.
