Skilled Nursing Facility: What It Is, Coverage & Difference From Nursing Home

Some of the most misunderstood aspects of Medicare coverage are the skilled nursing facility (SNF) benefit. Medicare Part A pays for skilled care in SNF for up to 100 days per benefit period for short-term skilled care after a qualifying hospital stay, if certain requirements are met. The 2026 structure of costs is three-tiered: Medicare pays 100% for the first 20 days, $217 per day for days 21-100 (up from $209.50 in 2025), and days 101 and beyond are not covered by Medicare. The most often forgotten rule is the 3-day qualifying inpatient hospital stay (QIHS), which is often surprising beneficiaries who are not aware that they must have been admitted to the hospital for 3 days for the stay to count as a qualifying stay for the QIHS rule, regardless of the length of time spent in the hospital. The 3-day rule will be eliminated for certain surgical procedures for beneficiaries participating in a new CMS demonstration beginning Jan. 1, 2026, through Dec. 31, 2030, although most beneficiaries will continue to have the 3-day rule in effect.

This guide outlines Medicare's skilled nursing facility coverage guidelines, cost, eligibility and changes for 2026. Medicare.gov, CMS and the Center for Medicare Advocacy provide the information. 

Medicare's 2026 SNF cost structure

Medicare Part A provides coverage for skilled nursing facility care and imposes a tiered cost-sharing model that many Medicare beneficiaries are not aware of. The structure is further complicated by the fact that it is implemented within "benefit periods" and not calendar years.

In 2026, you will have to pay the Part A deductible once for every benefit period (each time you enter the program). That includes the first 60 days of a hospital stay and two weeks of a skilled nursing facility stay (SNF) if the two services were in the same benefit period. If the hospital deductible was paid for the hospital stay in the same benefit period, it is not paid for the SNF stay.

Once the deductible is met, the first 20 days of SNF care are covered with no copayment per day.Days 1-20 of SNF care are covered after the deductible is met with $0 copayment per day. The facility is paid directly by Medicare and there is no out-of-pocket expense for these days other than the deductible paid.

Days 21-100 require a $217 daily coinsurance payment in 2026, up from $209.50 in 2025. This equates to $17,360 of out-of-pocket expenses for a 80-day cover (days 21-100). This is where Medigap supplement insurance can come into play as most Medigap plans cover this entire coinsurance.

Medicare doesn't pay for anything beyond day 101. Without other coverage such as Medicaid, long-term care insurance or VA benefits, the entire daily expense (which averages $314 in 2026) will be your responsibility. 

The 3-day qualifying hospital stay requirement

SNF coverage only begins after Medicare considers a hospitalization to be a "qualifying inpatient hospital stay.The SNF benefit of Medicare only begins after Medicare deems a hospitalization to be a "qualifying inpatient hospital stay. The requirement often leaves beneficiaries surprised, and can place a huge financial burden.

The 3-day requirement is strict in that you are required to have been admitted to the hospital as an inpatient on at least 3 consecutive days (this includes the day of admission but not the day of discharge). No day spent in the emergency room/observation status will count toward the 3-day requirement even if the day includes an overnight stay at the hospital.

This difference has been a matter of great policy discussion. For the same level of care, hospitals are increasingly making patients "observation status" instead of "inpatient" status, and sometimes for several days at a time. Federal NOTICE Act guidelines put in place in 2017 require hospitals to notify a patient of their observation status within 24 hours of the occurrence, instead of inpatient status. The notice contains details about the lack of admission of the patient and the financial consequence of the lack of admission for SNF coverage.

Hospitalization for observation only (no overnight stay) is usually not covered by Medicare SNF benefits. There is an appeals process available if a school is given observation status, but it is complex and the results are unpredictable. If you find you required SNF care after being on observation, there are other options such as home health (if applicable), private home care for the SNF, or maybe Medicaid (if you are qualified financially).

The new TEAM Demonstration, effective January 1, 2026, removes the 3-day requirement for beneficiaries who have five specific surgical procedures: total knee replacement, total hip replacement, total ankle replacement, total shoulder arthroplasty, and partial hip replacement. This demonstration is valid only for the participating hospitals and will end on 12/31/2030.

There may also be Medicare Advantage plans available that will also waive the 3-day minimum. If you have a Medicare Advantage plan, contact your plan to find out what SNF coverage requirements are prior to surgery or accepting placement into an SNF. 

How benefit periods work

Medicare benefit periods are central to understanding SNF coverage. A benefit period starts the day you're admitted as an inpatient to a hospital or SNF and ends after you've gone 60 consecutive days without any inpatient hospital care or skilled care in an SNF.

This means a single benefit period can extend across many months if you have multiple stays close together. Conversely, you can use multiple benefit periods within a calendar year if you have separate medical events with 60+ days between them.

Each new benefit period requires paying the Part A deductible again. There's no annual cap on benefit periods. Someone could theoretically have multiple benefit periods per year, each requiring a new deductible payment.

For each benefit period, Medicare provides up to 100 days of SNF coverage. After day 100, coverage stops entirely until a new benefit period begins (requiring another qualifying hospital stay and the 60-day gap).

Three practical scenarios illustrate this:

Scenario 1: After SNF coverage ends, the patient goes home. If they re-enter an SNF or hospital within 30 days for the same condition, no new qualifying hospital stay is needed for additional SNF coverage. They continue using days from the same benefit period.

Scenario 2: After SNF coverage ends, the patient goes home for 30-60 days, then has a new 3-day hospital stay. They can re-enter SNF care, but only if they need skilled care for a condition related to or treated during the new hospitalization. They continue using days from the same benefit period.

Scenario 3: After SNF coverage ends, the patient stays home for more than 60 consecutive days. The benefit period ends. Any future SNF coverage requires a new qualifying 3-day hospital stay and starts a new benefit period (with a new deductible).

Other Medicare SNF eligibility requirements

Beyond the qualifying hospital stay, several other conditions must be met for Medicare SNF coverage.

You must be enrolled in Medicare Part A and have days remaining in your benefit period. SNF care must commence within 30 days of hospital discharge. The care must be for a condition that was treated during your qualifying hospital stay, a chronic condition that was also being treated during the hospital stay (even if it wasn't the admission reason), or a new condition that started while you were getting SNF care for the original condition.

A Medicare-approved doctor must certify that you need daily skilled nursing care or therapy. "Daily" is interpreted as 5-7 days per week. The need must require professional skilled services, not just custodial care assistance.

The SNF must be Medicare-certified. Not all facilities accept Medicare, and not all that do have available Medicare beds. About 75% of nursing facilities are Medicare-certified nationally, with significant state variation.

Maintenance care coverage

A common misconception is that Medicare only covers SNF care when patients are likely to improve. This is false. Medicare covers skilled services needed to maintain a patient's current condition or to prevent or slow deterioration, not just services aimed at improvement.

The Jimmo v. Sebelius settlement (2013) clarified that Medicare coverage doesn't depend on whether the patient is likely to improve. Even if full recovery or medical improvement isn't possible, a patient may need skilled services to prevent further deterioration or preserve current capabilities. This is significant for patients with progressive conditions like multiple sclerosis, ALS, or advanced Parkinson's where rehabilitation goals focus on maintenance rather than improvement.

In practice, some SNFs are reluctant to bill Medicare for maintenance care because the documentation requirements are stricter and audit risk is higher. If you're being told Medicare won't cover SNF care because the patient isn't improving, this may be incorrect. Appealing or seeking a second opinion may be appropriate.
