The 100-Day Benefit Period: A Detailed Breakdown
Medicare's coverage for skilled nursing facility (SNF) care is structured around a "benefit period," which begins the day you are admitted as an inpatient to a hospital or SNF. The maximum coverage under Medicare Part A is up to 100 days within each benefit period. Your out-of-pocket costs vary significantly depending on how long your stay is, especially if you have Original Medicare.
Original Medicare Costs (2025)
For a single benefit period in Original Medicare, the costs for a SNF stay are broken down as follows:
- Days 1–20: You pay $0 for covered services after paying the applicable hospital deductible.
- Days 21–100: You pay a daily coinsurance, which is $209.50 per day in 2025.
- Days 101 and beyond: You are responsible for all costs.
Eligibility Requirements for SNF Coverage
To receive Medicare Part A coverage for a skilled nursing facility, you must meet several strict conditions:
- Qualifying Hospital Stay: A prior inpatient hospital stay of at least three consecutive days is required. Observation status does not count.
- Timely Admission: You must be admitted to a Medicare-certified SNF within a short time after hospital discharge, typically within 30 days.
- Daily Skilled Care: A doctor must determine you need daily skilled services, provided or supervised by professional staff.
- Medically Necessary: The skilled services must be reasonable and necessary for a condition related to your hospital stay or a new condition that developed in the SNF.
How a Benefit Period Works and Resets
Medicare's benefit period is crucial to understanding coverage limits. It starts with inpatient hospital or SNF admission and ends after 60 consecutive days without inpatient care. A new benefit period and up to 100 days of SNF benefits can begin after the previous one ends, following a qualifying 3-day hospital stay. There's no limit to the number of benefit periods, provided conditions are met each time.
Original Medicare vs. Medicare Advantage: A Comparison
Coverage for SNF care differs between Original Medicare and Medicare Advantage (Part C).
| Feature | Original Medicare (Part A) | Medicare Advantage (Part C) |
|---|---|---|
| Maximum Days | Up to 100 days per benefit period. | At least 100 days per benefit period. |
| Cost-Sharing | Defined coinsurance for days 21-100. | May have different cost-sharing (copayments) and could charge costs from day 1. |
| 3-Day Hospital Stay | Generally required. | May waive the 3-day stay requirement. |
| Network | Any Medicare-certified SNF. | May require in-network SNF. |
| Overall Rules | Standardized nationwide. | Rules and costs vary by plan. |
Planning for Extended or Non-Skilled Care
Since Medicare's SNF coverage is limited to skilled care, planning for extended stays or custodial care is essential.
When Medicare Coverage Ends
Coverage ends if you no longer need daily skilled care or have used all 100 days in a benefit period.
Alternative Payment Options
- Medigap Policies: May help cover coinsurance for days 21-100.
- Medicaid: Can cover long-term nursing home costs for eligible individuals.
- Long-Term Care Insurance: Private insurance for long-term care, including custodial care.
- Private Pay: Using personal funds.
- VA Benefits: Available for eligible veterans.
Conclusion
Understanding how many days will Medicare pay benefits for a skilled nursing facility is vital for planning. Medicare covers up to 100 days of medically necessary skilled care per benefit period, but it is not a solution for long-term care. Knowing the rules helps in financial preparation.
