Skilled nursing facility care is one of the most misunderstood Medicare benefits — and the gaps in coverage can be financially devastating without proper planning. Medicare Part A does cover SNF care, but only under specific conditions, only for skilled care (not custodial care), and only for a limited number of days. The daily coinsurance for days 21–100 is $209.50 in 2026, and Medicare stops paying entirely after day 100. Florida, with its large senior population, has thousands of skilled nursing facilities — but the rules for when and how Medicare pays are the same statewide. This guide explains the coverage rules, the qualifying hospital stay requirement, what Medicare never covers in an SNF, and how your supplemental coverage affects your total exposure.

When you qualify for Medicare-covered SNF care, the benefit is structured by day range within each benefit period:
| SNF Days | Medicare Pays | Your Cost |
|---|---|---|
| Days 1–20 | 100% of covered services | $0 |
| Days 21–100 | All covered costs minus daily coinsurance | $209.50/day in 2026 |
| Day 101 and beyond | Nothing | 100% of all costs |
The SNF benefit is measured in benefit periods, not calendar years. A benefit period begins the day you are admitted as an inpatient to a hospital or SNF and ends when you have not received inpatient hospital or skilled nursing care for 60 consecutive days. If you need SNF care again after a new benefit period begins — following a new qualifying hospital stay — you receive a fresh 100-day benefit, including new days 1–20 at $0 cost.
Before Medicare will cover any SNF care, you must have had a qualifying inpatient hospital stay of at least 3 consecutive days. The rules are strict:
If you are discharged from the hospital without a full 3-day inpatient stay, Medicare will not cover any subsequent SNF care, even if you genuinely need skilled nursing services. You would be responsible for the full cost out of pocket.
Observation status is one of the most consequential — and most frequently misunderstood — issues in Medicare SNF coverage. When a hospital places you under "observation" rather than formally admitting you as an inpatient, you are legally considered an outpatient, even if you spend multiple nights in the hospital.
Days spent under observation status do NOT count toward the 3-day qualifying inpatient hospital stay. You can spend 4 nights in the hospital under observation and still not qualify for Medicare-covered SNF care after discharge. Under the NOTICE Act, hospitals are required to provide a written Medicare Outpatient Observation Notice (MOON) to observation patients after 24 hours — if you or a family member is hospitalized and SNF care is a possibility, ask about your admission status explicitly.
Medicare's SNF benefit covers skilled care only. "Skilled" means care requiring the professional judgment of a licensed nurse, physical therapist, occupational therapist, or speech therapist. Services that are primarily custodial — helping someone with activities of daily living like bathing, dressing, eating, toileting, and mobility — are not covered by Medicare regardless of where they're provided.
Specifically, Medicare does NOT cover:
The long-term custodial care that most people associate with "nursing homes" — where a resident lives permanently and receives help with daily activities — is not covered by Medicare. In Florida, this care can cost $8,000–$12,000 per month or more. Funding must come from personal savings, Medicaid (for those who qualify financially after asset spend-down), or long-term care insurance.
Medigap Plan G specifically covers the Medicare Part A SNF coinsurance for days 21–100. In 2026, this eliminates the $209.50/day coinsurance that you would otherwise owe — a maximum exposure of approximately $16,760 for an 80-day stay from day 21 through day 100. With Plan G, your SNF cost-sharing through day 100 is effectively zero beyond the annual Part B deductible you already paid at the start of the year.
After day 100, however, neither Medicare nor Medigap pays. The SNF benefit runs out completely. Medigap supplements Medicare's coverage but does not extend Medicare's structural limits. Plan G holders have no additional SNF coverage once the 100-day benefit period ends.
Medicare Advantage plans must cover SNF care at least as generously as Original Medicare, but the structure differs in ways that matter significantly at the time of care:
If you or a family member is in the hospital and an SNF admission appears likely, contact your MA plan's member services line immediately — before discharge — to begin the authorization process and identify in-network SNF options near you.
Florida has one of the largest skilled nursing facility industries in the country. CMS rates SNFs on a 1-to-5 star scale at Care Compare (medicare.gov/care-compare), based on health inspection results, staffing levels, and quality-of-care measures. The star ratings are updated regularly and give beneficiaries and families a meaningful starting point for comparing facilities in any Florida county.
When selecting a Florida SNF following a hospital discharge, consider:

How many days does Medicare cover in a skilled nursing facility?
Medicare Part A covers up to 100 days per benefit period. Days 1–20 are covered at 100% with no cost to you. Days 21–100 require a $209.50/day coinsurance in 2026. After day 100, Medicare pays nothing — all costs are your responsibility.
What is the 3-day qualifying hospital stay requirement for Medicare SNF coverage?
You must have a qualifying inpatient hospital stay of at least 3 consecutive days (day of discharge doesn't count) within 30 days of your SNF admission. Observation status stays do not count — only formal inpatient admissions qualify. This distinction is critical and worth confirming with the hospital before discharge.
Does Medicare cover long-term care or nursing home care in Florida?
No. Medicare only covers skilled care — nursing, therapy, or rehabilitation services requiring licensed professionals. Custodial care (help with bathing, dressing, eating, mobility) and long-term nursing home stays are not covered. Long-term custodial care costs in Florida can exceed $8,000–$12,000/month and must be funded through personal savings, Medicaid, or long-term care insurance.
How does Medigap Plan G help with Medicare SNF costs?
Plan G covers the full $209.50/day SNF coinsurance for days 21–100 in 2026 — potentially $16,760 for an 80-day stay. After day 100, neither Medicare nor Medigap pays. With Plan G, your SNF cost exposure within the 100-day benefit window is essentially zero.
How do Medicare Advantage plans handle skilled nursing facility coverage differently?
MA plans must cover SNF care at least as generously as Original Medicare but typically require prior authorization, may apply different copay structures, restrict HMO enrollees to in-network SNFs, and some offer extended coverage beyond 100 days. Contact your MA plan before SNF admission to understand authorization requirements and find in-network facilities near you.
