Long-term care hospital services

Medicare Part A (Hospital Insurance) covers care in a long-term care hospital.

Your costs in Original Medicare

You pay this for each 

• benefit period:Days 1-60: $1,632 ($1,676 in 2025) deductible.*
• Days 61-90: $408 ($419 in 2025) each day.
• Days 91 and beyond: $816 ($838 in 2025) each day while using your 60 “lifetime reserve days.”
• Each day after you use all of your lifetime reserve days: All costs.

*You don’t have to pay a deductible for care you get in the long-term care hospital if you were already charged a deductible for care you got in a prior hospitalization within the same benefit period. This is because your benefit period starts on day one of your prior hospital stay, and that stay counts towards your deductible. For example, you won’t have to pay a deductible for your long-term care hospital care if:

• You’re transferred there directly from an acute care hospital
• You’re admitted to a long-term care hospital within 60 days of being discharged from a hospital
•
