Medicare Part A SNF coverage requires a qualifying 3-night inpatient hospital stay and must be ordered by a physician. Copay amounts are for 2026. Medigap and secondary insurance may cover some or all copays. Consult a Medicare counselor (SHIP) for individual guidance.
Medicare Part A covers SNF care up to 100 days per benefit period — but the coverage structure changes significantly at day 21. Here's exactly what families and administrators need to know.
| Benefit Period Days | Medicare Pays | Patient Pays (2026) | What This Means |
|---|---|---|---|
| Days 1–20 | 100% of approved costs | $0 per day | Medicare pays everything for the first 20 days. No cost to patient. |
| Days 21–100 | Covered above the daily coinsurance | $209.50/day | Patient pays $209.50 each day. Medigap (Plan C, D, F, G, M, N) may cover this. |
| Day 101+ | $0 — Medicare coverage ends | Patient pays 100% | Medicare Part A SNF benefit is exhausted. Patient pays full private-pay rate or qualifies for Medicaid if eligible. |
| Benefit Period Reset | — | — | After 60 consecutive days out of any SNF or hospital, a new benefit period begins — restoring full 100 days of coverage. |
Medicare SNF benefit periods have specific rules that directly affect care planning, discharge timing, and financial liability.
To qualify for Medicare Part A SNF coverage, a patient must have had a qualifying inpatient hospital stay of at least 3 consecutive nights. "Observation status" hospital days do NOT count toward this requirement — even if the patient was in the hospital for 3+ days.
Medicare Part A SNF coverage requires a daily skilled care need — physical therapy, occupational therapy, speech-language pathology, or skilled nursing services. When the skilled need ends, Medicare coverage ends, even if the patient still needs help with daily activities.
A new Medicare benefit period begins after 60 consecutive days out of any SNF or inpatient hospital. This resets the 100-day clock completely, restoring full first-20-day coverage. Many families are unaware that re-hospitalization may restart — not extend — the benefit period.
Medicare Supplement (Medigap) plans C, D, F, G, M, and N may cover the coinsurance amount for days 21–100. Families should check their secondary coverage before assuming full out-of-pocket liability. Medicare Advantage plans have their own SNF benefit structures that differ from Traditional Medicare.
