Medicare Part A covers up to 90 days of inpatient hospital care in each benefit period.
Benefit Period: A benefit period begins the day you're admitted as an inpatient in a hospital and ends when you haven't received inpatient hospital care for 60 days in a row.
Lifetime Reserve Days: After using the initial 90 days in a benefit period, you can use up to 60 additional lifetime reserve days. These days can be used only once during your lifetime but can be split among different hospital stays.
After 90 days: After day 90 in a benefit period, you will pay a coinsurance for each lifetime reserve day used. Once you use all 60 of your lifetime reserve days, you are responsible for all hospital costs.
For Skilled Nursing Facility (SNF) Care:
Medicare Part A covers up to 100 days of skilled nursing facility care in each benefit period.
Conditions: To qualify for SNF coverage, you typically need to have had a qualifying hospital stay of at least three days.
Coinsurance: You pay nothing for the first 20 days of covered skilled nursing care. From days 21 to 100, you pay a daily coinsurance.
After 100 days: You are responsible for all costs beyond 100 days.
