The benefit period is the amount of time during which Medicare pays for hospital and skilled nursing facility (SNF) services. A benefit period begins the day you are admitted to a hospital as an inpatient, or to a SNF, and ends the day you have been out of the hospital or SNF for 60 days in a row. With each new benefit period, you pay a new deductible. Your coinsurance is determined by the number of days you have been in the facility during each benefit period.
