Does Medicare cover skilled nursing facility (SNF) care?
Yes — but only if you clear three gates that trip up most families: a qualifying inpatient hospital stay, daily skilled care, and a Medicare-certified SNF. Twenty years inside Social Security taught me the 3-day rule trips up more families than any other Medicare benefit. Here's how it actually works.

Does Medicare cover skilled nursing facility (SNF) care?
Medicare Part A covers skilled nursing facility care up to one hundred days per benefit period after a qualifying inpatient hospital stay of at least three consecutive days. Days one through twenty are fully covered; days twenty-one through one hundred carry a daily coinsurance. Custodial care alone is not covered.
If you're trying to figure out whether a parent's hospital stay qualifies — or whether the SNF will accept Medicare for the days ahead — this is where most people pause and ask for a second set of eyes. That's what Chapter is for.
Free help from licensed Medicare advisors
Chapter is the partner I trust to walk through Medicare's coverage rules with families — including the SNF benefit, observation-status traps, and what comes next when the one-hundred-day clock runs out. Their licensed advisors don't push a plan; they help you read the rules. Free service.
Here's what to do, in 4 steps.
The SNF benefit is one of the most-misunderstood pieces of Medicare. The four steps below are the ones I tell every family. Do them in order, before discharge if you can.
1. Confirm inpatient vs. observation status BEFORE discharge
Ask the hospital case manager: 'Is my admission inpatient or observation?' Get the answer in writing on the MOON notice (Medicare Outpatient Observation Notice). Only inpatient nights count toward the 3-day rule. Observation nights look identical from a hospital bed but break SNF coverage.
42 CFR § 409.30 (basic SNF requirements) ›2. Get a copy of the MOON notice
If the hospital classified the stay as observation, federal law requires they hand you the MOON within 36 hours. Read it. Sign it (signing acknowledges receipt, not agreement). Keep a copy. This document is your proof of status if you later need to appeal.
Medicare.gov — MOON notice ›3. Confirm the SNF is Medicare-certified
Not every nursing home is Medicare-certified for SNF coverage. Use Medicare's Care Compare tool to verify before admission. A non-certified facility means zero Medicare payment, even if every other gate is cleared.
Medicare Care Compare — SNFs ›4. Track the day count and watch for the day-21 cliff
Mark day one as the first day in the SNF (not the hospital). Days 1–20 are fully covered; day 21 starts the daily coinsurance. Many families don't realize the cost hits on day 21 until the bill arrives. Plan for it. The benefit caps at day 100 per benefit period.
42 CFR § 409.61 (benefit limits) ›The SNF benefit, by the numbers
Which of these sounds more like you?
Different families hit this question from different angles. Pick the one that sounds most like you and I'll walk through what matters first.
I'm being discharged to a SNF and want to know if Medicare covers itCoverage hinges on three gates that close fast
Three gates have to be open at the same time. First, you need a qualifying inpatient hospital stay of at least three consecutive days, not counting your discharge day. Second, the SNF admission has to happen within 30 calendar days of hospital discharge. Third, you have to need daily skilled care — skilled nursing 7 days a week or skilled therapy at least 5 days a week — that's related to the condition treated in the hospital.
If any one of those gates is closed, Medicare doesn't pay. The Part A SNF benefit caps at 100 days per benefit period, with full coverage for days 1–20 and a daily coinsurance for days 21–100.
I've seen people assume any 3-night hospital stay counts. It doesn't. Inpatient nights count; observation nights don't. The MOON notice tells you which one you got — read it before you sign anything.
Mom was in the hospital 4 nights but Medicare won't cover her SNFLikely an observation-status problem
This is the single most common SNF denial I see. Hospitals sometimes classify a patient as 'observation' instead of 'inpatient' — same bed, same care, totally different Medicare status. Observation nights don't count toward the 3-day rule, so even a 4- or 5-night observation stay can result in zero SNF coverage.
The MOON notice (Medicare Outpatient Observation Notice) is the document hospitals must give within 36 hours of an observation stay. If you got one, your stay was observation, not inpatient. Appeal options exist but the rules are tight — see the observation-status-trap page for next steps.
Don't get caught by this — ask BEFORE discharge whether the stay was inpatient or observation. If observation, your SNF coverage may not exist. The MOON tells you, but only if you read it.
We were told it was free — then a bill arrived on day 21Day 21 is when the daily coinsurance kicks in
Days 1–20 are fully covered by Medicare. Starting day 21, you owe a daily coinsurance — $209.50/day at the 2025 rate (CMS announces the 2026 rate each fall). For a full coinsurance run from day 21 through day 100, that's roughly $16,760 out of pocket at the 2025 rate.
Medigap (Medicare Supplement) plans typically cover this coinsurance. If you have one, check your policy. If you don't, the day-21 cliff is real — plan for it.
Don't get caught by this — the SNF won't always remind you on day 20 that the meter starts tomorrow. Mark your own calendar.
Day 100 is approaching — what happens next?Medicare stops paying; Medicaid LTC may be the next door
On day 101, Medicare's SNF benefit ends for that benefit period. After that, the cost is yours — unless you qualify for Medicaid long-term care, which has its own asset and income tests and is administered state-by-state.
The benefit period resets after 60 consecutive days with no inpatient or SNF care. So a future hospitalization plus another qualifying SNF stay could open a new 100-day window. But families running out of days now usually need to start the Medicaid LTC conversation immediately — the application can take months.
I'm a flashlight, not a courtroom — Medicaid LTC eligibility is state-specific and the rules around look-back, spend-down, and spousal protections are dense. An elder-law attorney is worth the consult.
Mom just needs help with bathing and meals — will Medicare pay?Custodial care alone isn't covered by Medicare
Help with bathing, dressing, eating, and other activities of daily living — the technical term is 'custodial care' — isn't covered by Medicare's SNF benefit on its own. Medicare requires daily skilled need: skilled nursing 7 days/week, or skilled therapy at least 5 days/week.
If the only need is custodial, look at Medicaid LTC, long-term-care insurance if you have a policy, or in some cases home and community-based services waivers (HCBS) through Medicaid that may cover home aides instead of facility care.
Most people don't realize Medicare was never designed to pay for long-term custodial care. It's a medical-recovery benefit, not a residential one. Confusing the two costs families thousands.
I'm in a Medicare Advantage plan — do these rules still apply?MA plans must cover at least Original Medicare's SNF benefit
Medicare Advantage plans are required by law to cover at least the same benefits as Original Medicare — including the SNF benefit. But cost-sharing and prior-authorization rules can vary by plan. Some MA plans waive the 3-day inpatient rule. Some require prior authorization before you transfer to a SNF. Some have different daily copays than the Original Medicare coinsurance.
Check your plan's Evidence of Coverage document or call the plan directly. The Original Medicare rules above are your floor; your specific MA plan may have additional features.
I'm a flashlight, not a courtroom — your MA plan's specific rules live in your Evidence of Coverage. Read it before you need it. SHIP at can help you decode it.
I'm helping my parent figure out their SNF coverageSame gates apply; you're the second set of eyes
Helping a parent or spouse navigate this is one of the most useful things you can do. The gates are the same whether they or you are the patient — qualifying inpatient stay, daily skilled need, certified facility — but you can be the person who catches an observation-status problem before it becomes a denied claim.
What you'll need: their Medicare number (red, white, and blue card), the hospital's discharge paperwork, the MOON notice if observation, and the SNF's Medicare certification status. If they want you to talk to Medicare on their behalf, they'll need to authorize it via Form CMS-10106 (Authorization to Disclose Personal Health Information).
I'm a flashlight, not a courtroom — if your parent can't communicate decisions, you may need a healthcare power of attorney to act on their behalf. Get one set up before the crisis if at all possible.
My situation isn't quite any of theseTalk to a licensed Medicare advisor
SNF coverage questions get specific fast — swing-bed hospitals, ESRD patients, hospice election interactions, dual-eligible Medicare-Medicaid scenarios, appeals after a denial. If your situation doesn't fit cleanly into the cards above, the right next step is usually a 15-minute call with someone who's seen the specific edge case before.
SHIP (State Health Insurance Assistance Program) at is free, federally funded, and unbiased — they help with coverage questions, appeals, and understanding your specific Medicare picture. The Chapter card on this page is another route: licensed Medicare advisors who help families read the rules.
I'm a flashlight, not a courtroom — some of the harder edge cases (post-denial appeals, ALJ hearings, dual-eligible coordination) are worth a call with an elder-law attorney too.
Other programs to look at
Medicare's SNF benefit ends at one hundred days per benefit period. Many families discover the next chapter is Medicaid long-term care — different program, different rules. Here are the related programs worth knowing about now, before the clock runs out.
Medicare Part A (Hospital Insurance)
If you're enrolled in Medicare, Part A is the program that pays for the SNF benefit described on this page. Most people get Part A premium-free at age 65 if they or a spouse paid Medicare taxes for 40 quarters.
Medicaid Long-Term Care
When Medicare's 100-day SNF benefit ends and care is still needed, families with limited income and assets may qualify for Medicaid long-term care, which can pay for ongoing nursing-home stays. Rules vary by state.
Medicaid Nursing Home Coverage
Once Medicare's SNF days run out, Medicaid is the most common payer for ongoing nursing-home care. You may qualify if your income and countable assets fall below your state's thresholds; spousal-impoverishment protections shield some assets for a community spouse.
Home and Community-Based Services (HCBS) Waivers
If facility care isn't the only option, you may qualify for Medicaid HCBS waivers that pay for home aides, adult day care, and other supports that keep people out of nursing homes. Available through state Medicaid programs.
Medicare Home Health Benefit
If you don't qualify for SNF coverage but need skilled nursing or therapy at home, you may qualify for Medicare's home health benefit — no 3-day rule, no SNF cap, but its own homebound and skilled-need requirements.

Everything people ask me
How many days does Medicare cover skilled nursing facility care?
Medicare Part A covers up to 100 days of skilled nursing facility care per benefit period. Days 1–20 are fully covered after the Part A inpatient hospital deductible has been met. Days 21–100 carry a daily coinsurance (the 2025 rate was $209.50/day; CMS announces the 2026 rate each fall). After day 100, Medicare pays nothing for SNF care in that benefit period.
What is the 3-day rule for Medicare SNF coverage?
Medicare requires a qualifying inpatient hospital stay of at least 3 consecutive calendar days, not counting the day of discharge, before it will pay for SNF care. The stay must be inpatient — observation status doesn't count, even if you spent multiple nights in a hospital bed. The SNF admission must also happen within 30 days of hospital discharge.
Why won't Medicare cover my SNF stay if I was in the hospital for 4 nights?
Most likely your hospital stay was classified as observation status, not inpatient. Observation patients may stay multiple nights in a hospital bed, but Medicare counts those nights as outpatient — they don't satisfy the 3-day inpatient rule. Hospitals are required to give you a MOON (Medicare Outpatient Observation Notice) within 36 hours of an observation stay; if you got one, that's your answer.
What does Medicare actually pay during a SNF stay?
Medicare pays the full Medicare-approved amount for days 1–20, with no coinsurance. For days 21–100, Medicare pays everything except a daily coinsurance amount that you (or your Medigap plan) owe. The 2025 daily coinsurance was $209.50/day; the 2026 rate is announced by CMS each fall. After day 100, Medicare pays nothing in that benefit period.
What happens after Medicare's 100 days run out?
On day 101, Medicare's SNF benefit ends for that benefit period. From there, the daily cost is the patient's responsibility unless they qualify for Medicaid long-term care or have long-term-care insurance. Medicaid LTC has its own income and asset tests and is run state-by-state — the application process can take weeks to months, so most families need to start it well before day 100.
Does Medicare cover custodial care — help with bathing, dressing, eating?
No. Medicare's SNF benefit covers skilled care — daily skilled nursing or skilled therapy needed because of a hospital-treated condition. Help with activities of daily living (bathing, dressing, eating, toileting) on its own is custodial care, which Medicare does not cover. Medicaid long-term care, HCBS waivers, or private long-term-care insurance are the typical pathways for custodial care.
Who decides whether the patient still needs skilled care?
The SNF's care team and the Medicare Administrative Contractor (MAC) review medical records to determine ongoing skilled need. If the SNF concludes skilled care is no longer needed, Medicare's payment ends. The patient has the right to request a fast-track appeal through the Beneficiary and Family Centered Care Quality Improvement Organization (BFCC-QIO) before discharge from skilled coverage — ask for it before you check out.
What is the SNF benefit period and when does it reset?
A benefit period begins the day you're admitted as an inpatient to a hospital or SNF and ends after 60 consecutive days when you've received no inpatient or SNF care. Once a benefit period ends, a new one begins at your next qualifying admission — with a fresh 100-day SNF clock and a new Part A inpatient deductible. There's no annual or lifetime limit on the number of benefit periods.
What if I'm in a Medicare Advantage plan instead of Original Medicare?
Medicare Advantage plans are required by law to cover at least the same benefits as Original Medicare, including the SNF benefit. However, MA plans can structure cost-sharing differently — daily copays may differ from the Original Medicare coinsurance, prior authorization may be required, and some plans waive the 3-day inpatient rule. Check your plan's Evidence of Coverage or call the plan directly. SHIP at can help you decode it.
Can I appeal if Medicare denies SNF coverage?
Yes. There are five levels of appeal: redetermination by the Medicare Administrative Contractor, reconsideration by a Qualified Independent Contractor, ALJ hearing, Medicare Appeals Council review, and federal district court. Strict deadlines apply at each step. For a denial of ongoing skilled care while still in a SNF, you can also request a fast-track BFCC-QIO appeal within hours. SHIP can help you understand which path fits your situation.
