Medicare covers most of the cost of a hospital stay, but your out-of-pocket share depends on how long you’re admitted. For the first 60 days, you pay a single deductible and nothing else for the room, meals, nursing care, and other hospital services. After day 60, daily coinsurance charges begin, and they increase significantly the longer you stay.
What You Pay for the First 60 Days
Every hospital stay begins with a Part A deductible, which covers days 1 through 60 in full. Once you’ve paid that deductible, Medicare picks up the entire tab for a semi-private room, meals, general nursing, drugs administered during your stay, and other inpatient services. Most people who are hospitalized go home well within 60 days, so the deductible is the only cost they face from Part A.
One important detail: this deductible is charged per “benefit period,” not per calendar year. A benefit period starts the day you’re admitted as an inpatient and ends when you’ve been out of the hospital (and out of a skilled nursing facility) for 60 consecutive days. If you’re discharged and then readmitted within that 60-day window, you’re still in the same benefit period and won’t owe another deductible. But if you’re readmitted after the 60-day gap, a new benefit period begins and you’ll pay the deductible again.
Costs After Day 60
Stays longer than 60 days trigger daily coinsurance. For days 61 through 90, you pay a set amount per day while Medicare continues to cover the rest. If your stay extends past 90 days, you begin drawing on a separate pool called lifetime reserve days.
You get 60 lifetime reserve days total, and each one costs $868 per day in 2026. These days do not renew. Once you’ve used all 60, they’re gone permanently. For days 91 through 150, that $868 daily charge is your responsibility for as long as your reserve days last. After your reserve days run out, Medicare stops paying entirely, and you’re responsible for all costs.
Doctor Services Are Billed Separately
Here’s something that catches many people off guard: the doctors who treat you in the hospital bill separately from the hospital itself. Your surgeon, anesthesiologist, radiologist, and other physicians are covered under Part B, not Part A. After you meet the Part B deductible, you generally pay 20% of the Medicare-approved amount for those doctor services. This means you’ll receive bills from the hospital and from individual physicians, even for a single stay.
Blood Transfusions
If you need blood during your hospital stay, Medicare requires you to cover the cost of the first 3 pints per calendar year. After those 3 pints, Medicare pays in full. You can also avoid the charge if you or someone else donates blood to replace what was used.
Observation Status Changes Everything
Not everyone who spends the night in a hospital is technically an “inpatient.” If your doctor hasn’t written an order to admit you, you’re classified as an outpatient receiving observation services, even if you sleep in a regular hospital bed for one or more nights. This distinction matters more than most people realize.
As an outpatient, your hospital services are billed under Part B instead of Part A. That means different copayments for drugs, lab tests, and other services. While the copayment for any single outpatient service can’t exceed the inpatient deductible, your total copayments across all outpatient services can add up to more than the inpatient deductible would have been.
Observation status also affects what happens after you leave. Medicare only covers care in a skilled nursing facility if you first had a qualifying inpatient stay of at least 3 consecutive days. Time spent under observation doesn’t count toward those 3 days. So if you were in the hospital for 4 nights but classified as an outpatient the whole time, Medicare won’t cover the skilled nursing care you might need afterward.
Hospitals are required to give you a written notice called a Medicare Outpatient Observation Notice (MOON) if you’ve been receiving observation services for more than 24 hours. This notice explains your status and how it affects your costs both during and after your hospital visit. If you’re unsure about your status, ask directly.
Skilled Nursing Facility Coverage After Discharge
When you do have a qualifying 3-day inpatient stay, Medicare covers up to 100 days of skilled nursing facility care per benefit period. The first 20 days are fully covered. Days 21 through 100 require a daily coinsurance payment of $217 in 2026. After day 100, Medicare stops covering skilled nursing care entirely for that benefit period.
Psychiatric Hospital Stays
If you’re admitted to a freestanding psychiatric hospital rather than a general hospital’s psychiatric unit, Medicare imposes a lifetime cap of 190 days. Once you’ve used those 190 days across your entire time on Medicare, Part A will no longer pay for inpatient psychiatric hospital care. Care in a general hospital’s psychiatric ward follows the standard Part A rules with no lifetime cap beyond the reserve day limits.
What Medicare Doesn’t Cover
Medicare covers a semi-private room, but a private room is only covered when it’s medically necessary, such as for isolation due to an infection. If you request a private room for personal preference, you’ll pay the difference. Private-duty nursing, where a nurse is assigned exclusively to you rather than shared among patients on the floor, is also not covered. Personal items like a phone or television in your room are your responsibility as well.
