As long as you are homebound and need skilled care, there is no prior hospital stay requirement for Medicare Part B coverage of home health care. There is no deductible or coinsurance for Part B covered home health care.
While home health care is normally covered by Part B, if you have been in the hospital as an inpatient for three days, or have been in a skilled nursing facility after a hospital stay, Medicare Part A covers your first 100 days of home health care. Any additional days will then be covered by Medicare Part B. Regardless of whether your care is covered under Medicare Part A or Part B, Medicare pays the full cost.
