What a hospital stay costs under Original Medicare in 2026: the deductible, day 61, day 91
Part A prices a hospital stay by the benefit period, not the calendar year, and the daily rate changes at day 61 and again at day 91. Here are the 2026 figures from Medicare.gov and CMS, plus the observation-status rule that decides whether Part A pays at all.
Key takeaways
- Each Part A benefit period starts with a $1,736 deductible, then $434 a day from day 61 and $868 a day from day 91 using your 60 lifetime reserve days.
- A night in a hospital bed under observation is outpatient care billed to Part B, and it does not count toward the 3-day stay that unlocks skilled nursing coverage.
- Ask each day whether you are an inpatient, keep any MOON notice you are handed, and check what covers these gaps before you need them.
You have Original Medicare and a hospital stay is coming, or has just happened. Here is what Part A charges in 2026, in the order you would meet them.2
What is a Medicare benefit period?
Part A prices a hospital stay by the benefit period, not the calendar year. The period starts the day you are admitted as an inpatient to a hospital or a skilled nursing facility. It ends once you have gone 60 days in a row with no inpatient hospital care and no skilled care in a nursing facility.1 Go back in after that and a new period starts, with a new deductible: two admissions four months apart mean two deductibles.2
What do you pay for a hospital stay in 2026?
| Days in one benefit period | What you pay in 2026 |
|---|---|
| Days 1 to 60 | The Part A deductible, $1,736, then $0 a day3 |
| Days 61 to 90 | $434 a day3 |
| Days 91 to 150 | $868 a day, drawing on your 60 lifetime reserve days3 |
| After day 150, or once the reserve days are gone | All costs2 |
Lifetime reserve days are 60 extra days Medicare helps pay for after day 90 of a benefit period. You get 60 for life, not 60 per stay, and they do not refill.1
Those amounts cover the hospital’s charges. Doctors who treat you there bill Part B: usually 20% of the Medicare-approved amount after the $283 yearly Part B deductible.2

Part A covers up to 100 days of skilled nursing facility care in each benefit period, generally only after a qualifying inpatient hospital stay of at least 3 days in a row, counted from the day you are admitted and not counting the day you leave.4 The rule can be waived if your doctor is in an Accountable Care Organization approved for the waiver, and some Medicare Advantage plans waive it too.4 You generally have to enter the facility within 30 days of leaving the hospital and need daily skilled care.4
Days 1 to 20 cost $0 a day if you already paid the deductible in the same benefit period.4 Days 21 to 100 cost $217 a day.3 From day 101 you pay all costs.4 Medicare does not pay for long-term custodial care.
Why does “observation status” change the bill?
You can spend two nights in a hospital bed and never be an inpatient: without a doctor’s admission order, you are an outpatient receiving observation services. Part B pays, not Part A.5 Those nights do not count toward the 3-day stay that unlocks skilled nursing coverage.4
The hospital must give you a written Medicare Outpatient Observation Notice (MOON) if you receive observation services for more than 24 hours, and no later than 36 hours after they begin, or at discharge if sooner; it explains why you are an outpatient and what that means for your costs.56 Medicare.gov says admission is generally appropriate when your doctor expects you to need 2 or more midnights of medically necessary hospital care, but the doctor has to order it.5
What covers these gaps?
Original Medicare has no yearly limit on what you pay out of pocket;2 we reported in July on Benefits Insider on what that one line means for the whole Medicare decision. Two kinds of coverage put a ceiling on it.
A Medigap policy pays your share of Part A and Part B costs. Every lettered Medigap plan pays the Part A hospital coinsurance and adds up to 365 more hospital days after Medicare’s run out, and every plan except Plan A pays at least part of the Part A deductible (Plans K, L and M pay a percentage of it).7 Plans F and G also come in high-deductible versions in some states that pay nothing until you meet their deductible,7 and Massachusetts, Minnesota and Wisconsin standardize Medigap differently.9
The other route is a Medicare Advantage plan, a different way to receive your Medicare rather than a supplement. It replaces the Part A schedule above with its own copays and a yearly out-of-pocket maximum. Once you reach the plan’s limit, it pays 100% of covered Part A and Part B services for the rest of the calendar year.2 Plans may set separate in-network and out-of-network limits, and your premiums, Part D drug costs and services the plan does not cover are outside it.10 Plans may charge copays in the first 60 hospital days.1
Which path fits you is covered in Medigap or Medicare Advantage; the window for buying Medigap without health questions is in our enrollment guide.
What to do
- Before a planned admission, ask whether you will be admitted as an inpatient, and get the answer in writing.
- Ask every day whether you are an inpatient or under observation, and keep any MOON notice with your discharge papers.
- Before a transfer to a skilled nursing facility, have the discharge planner confirm your 3 inpatient days, or that a waiver applies.4
- After discharge, check your Medicare Summary Notice at Medicare.gov or call 1-800-MEDICARE (1-800-633-4227) to see what was billed to Part A and what to Part B; on a Medicare Advantage plan, use the plan’s own claims statement.8
- For free counseling on these choices, call your State Health Insurance Assistance Program (SHIP), reached through Medicare.gov’s Talk to Someone page.8
- If your income is limited, ask your state Medicaid office about Medicare Savings Programs, which can pay Part A and Part B costs; we list the programs.
