Quick answer: Medicare Part A can cover skilled nursing facility (SNF) care when official eligibility conditions are met. Medicare.gov says you generally need a qualifying inpatient hospital stay of at least three days in a row, counting the admission day but not the discharge day, and that time in observation or the emergency room before inpatient admission does not count. You generally must enter the SNF within a short time (Medicare.gov says generally 30 days) after leaving the hospital, need daily skilled care, use a Medicare-certified SNF, and have benefit-period days left. For each benefit period in 2026, Medicare.gov lists $0 coinsurance for days 1–20 after the $1,736 Part A deductible (you do not pay that deductible again for the SNF stay if you already paid it for a hospital stay in the same benefit period), $217 per day for days 21–100, and all costs from day 101 on. Medicare Advantage plans can use different copays and may waive the three-day rule; always ask the hospital and the plan. This explainer sits in our Medicare guide.

What Counts as a Qualifying Stay, and What Does Not
A skilled nursing facility is not the same thing as a long-term nursing home stay for custodial care. Medicare.gov describes SNF care as skilled nursing or skilled therapy that must be performed by, or under the supervision of, professionals, to treat, manage and observe your condition. Covered services can include a semi-private room, meals, skilled nursing, physical, occupational and speech therapy when needed to meet your health goal, medical social services, medications, medical supplies used in the facility, and certain ambulance transportation, according to the official coverage page.
The three-day rule is the hurdle families hear about too late. Official language requires a prior medically necessary inpatient hospital stay of at least three days in a row, starting the day you were admitted as an inpatient, not including the day you leave the hospital. Observation time and emergency-room time before inpatient admission do not count, even if you were in the hospital overnight. A stay that feels like “three nights in the hospital” can fail the test if some of those nights were observation.
Medicare.gov notes exceptions in limited official programs: you may not need the three-day inpatient stay if your doctor participates in an Accountable Care Organization approved for a Skilled Nursing Facility 3-Day Rule Waiver. Medicare Advantage Plans may also waive the three-day requirement. Those waivers are not automatic for every patient. Ask the doctor, the hospital case manager and, if you have Advantage, the plan, before you assume Medicare will pay the SNF bill.
If a hospital later changes an inpatient admission to outpatient observation, official materials describe a possible appeal path for some status changes going back to January 2009. That appeal, if successful, can affect both the hospital claim and related SNF coverage. It is technical; use the official instructions and consider SHIP or legal-aid help rather than treating this paragraph as a filing guide.
Eligibility also requires Part A with days left in the benefit period, daily skilled care as a doctor has decided you need, services in a Medicare-certified SNF, and a need for skilled care for an ongoing condition treated during the hospital stay (even if it was not the admission diagnosis) or for a new condition that starts while you are already getting SNF care for that ongoing condition. Official language also says you need the skilled care to improve or maintain your current condition, or to prevent or delay it from getting worse. Entering the SNF generally must happen within a short time, generally 30 days, after leaving the hospital, according to Medicare.gov.
Custodial care by itself — help with bathing, dressing or eating when no skilled service is required — is generally not what the Part A SNF benefit is for. A facility may still offer that care, but Medicare payment is a separate question. Always ask what Medicare is expected to cover, in writing if you can.
2026 Costs, Benefit Periods and How Stays End
Official 2026 figures on Medicare.gov, which match the CMS year-2026 deductible and coinsurance announcement, are:
- Days 1–20: $0 each day after you pay the $1,736 Part A deductible. You do not have to pay that deductible again for the SNF stay if you already paid it for hospital care in the same benefit period.
- Days 21–100: $217 each day.
- Days 101 and beyond: you pay all costs.
Part A limits SNF coverage to 100 days in each benefit period. A benefit period is an official Medicare unit of time, not a calendar year. It generally starts the day you are admitted as an inpatient or to a SNF, and it ends when you have been out of a hospital or SNF for 60 days in a row, as official Medicare materials describe. A new benefit period can mean a new Part A deductible. This article does not invent examples that stretch those rules; confirm the definition on Medicare.gov if you have had back-to-back stays.
If you have a Medicare Advantage Plan, cost-sharing can look different. Medicare.gov notes that an Advantage plan may charge copayments during the first 20 days. The plan’s Evidence of Coverage, not the Original Medicare coinsurance chart, is what you should use, and the plan may also handle prior authorization. Call the plan before transfer, and get a written coverage decision when one is required.
Medigap policies, if you have Original Medicare and a supplement, may pay some SNF coinsurance depending on the plan letter. That is a policy-contract question and a reason to read the official plan outline or our Medigap comparison materials, not a promise that every supplement pays every SNF day. Medicare Savings Programs may also help some people with costs; see official Extra Help and Savings Program pages.
Coverage can end before day 100 if you no longer meet skilled-care criteria, if you leave the facility, or if you refuse daily skilled care in a way official rules treat as ending the need. Facilities should issue official notices when coverage will end, and you may have appeal rights, including a fast review in some cases, as discussed in our Medicare appeals guide and on the notice. Use those official notices rather than a hallway conversation as the last word.
If the hospital has its own SNF bed, you may be able to stay there; if not, you will need a Medicare-certified facility with an available bed. Quality and location are your choice among certified options; payment still depends on the eligibility rules above. CareCompare on Medicare.gov is an official tool for looking up facilities.
Ask how therapy minutes, physician visits and medications will be billed, and whether any services will be billed separately to Part B. Unexpected bills often come from assuming “Medicare is covering the stay” means every professional who walks into the room is included.
For 2027 hospital and SNF deductibles and coinsurance, use the CMS announcement and Medicare.gov cost pages when they are published. This article does not invent 2027 Part A amounts. The 2026 figures above were current on official pages when checked in November 2026.
Related coverage decisions about hospitals, observation status and Parts A and B basics will help you see why admission status matters so early. If money is tight, ask a social worker about Medicaid, Veterans benefits or other official programs, as Medicare.gov also suggests when the three-day rule is not met.
Questions to Ask Before a Transfer, and How Billing Can Split
Before a hospital discharge planner names a skilled nursing facility, ask four official questions and write down the answers. Was the hospital stay inpatient from the day the staff are counting, or was some of the time observation? Does the doctor expect daily skilled care that official Medicare rules would recognize? Is the facility Medicare-certified, and has a bed been accepted? If you have a Medicare Advantage Plan, has the plan authorized the stay, and does the plan waive or still require the three-day inpatient rule?
Those answers belong next to the 2026 coinsurance figures, or the Advantage copay chart, so the family is not surprised on day 21. People with Original Medicare and a Medigap policy should also ask which plan letter they have and whether that policy is designed to pay SNF coinsurance. Standardized comparisons such as Plan G versus Plan N are a starting point; the policy itself is the authority. People with limited income should ask a social worker about Medicare Savings Programs and Extra Help, because official programs can help with premiums or cost-sharing when eligibility rules are met.
Billing can split even during a covered stay. Physician visits, certain therapy arrangements, ambulance trips, and hospital outpatient services may generate separate Part B claims. Ask the facility which services are bundled into the SNF stay and which will be billed separately. Request an official notice if the facility believes Medicare coverage will end, and use the appeal rights on that notice rather than waiting for a later collection letter.
Readmission to the hospital from a SNF, or a gap in skilled care, can affect the benefit period and the day count. Official Medicare.gov materials discuss what happens if you stop getting skilled care or leave the facility; confirm those rules for the actual dates rather than assuming a new 100-day clock automatically starts. A case manager or SHIP counselor can help you map dates onto the official benefit-period definition.
Quality and location are still your choice among certified facilities. Medicare.gov’s Care Compare tool is an official source for inspection and quality measures. Payment eligibility and quality scores are different questions. A high-rated facility can still bill you if the three-day rule was not met, and a covered stay can still occur at a more modest certified facility.
Keep the hospital admission paperwork, the inpatient-versus-observation status, the SNF admission agreement, authorizations from an Advantage plan, and the first month of bills together. Those documents are what an appeal or a later question about the $217 daily coinsurance in 2026 will require.
Frequently Asked Questions
Do observation nights count toward the three-day stay?
No. Medicare.gov says time in observation or the emergency room before you are admitted as an inpatient does not count, even if you stay overnight.
How much is SNF coinsurance in 2026?
Official Medicare.gov figures are $0 per day for days 1–20 after the $1,736 Part A deductible (not charged again if already paid in the same benefit period), $217 per day for days 21–100, and all costs after day 100.
Does Medicare Advantage use the same three-day rule and the same copays?
Not always. Official materials say Advantage plans may waive the three-day stay and may charge copays even in the first 20 days. Check with your plan.
Is a skilled nursing facility the same as long-term custodial nursing-home care?
No. The Part A SNF benefit is for medically necessary skilled care under official conditions, generally for a limited number of days in a benefit period, not for ongoing custodial care by itself.
How soon must I go to the SNF after the hospital?
Medicare.gov says you generally must enter the SNF within a short time, generally 30 days, of leaving the hospital.
What if the hospital says I was an outpatient the whole time?
Ask for the official status in writing, talk with the case manager, and read official observation and appeal information on Medicare.gov. Observation can block a qualifying inpatient stay even after several nights.
