If Dad was discharged from a hospital for 100 days of rehab at a skilled nursing facility, and if Dad goes back to the hospital from rehab, does Medicare restart Dad's 100-day rehab benefit?

A return to the hospital may extend skilled nursing facility coverage by the number of days one spends in the hospital, because the time spent in the hospital should not count toward the 100 days. However, Dad will not receive a new 100-day allotment until he has been out of the hospital and the skilled nursing facility for at least 60 days.
