Medicare Part A Benefit Periods: Why You Can Pay the Hospital Deductible Twice

If you've ever looked at a Medicare summary and wondered why the hospital deductible might appear more than once in the same calendar year, you're not alone. Unlike most insurance deductibles that reset on January 1 and stay reset, the Medicare Part A inpatient hospital deductible works differently. It's tied to something called a "benefit period," and understanding how benefit periods start and end is the key to understanding your potential out-of-pocket costs for hospital and skilled nursing facility (SNF) care.

What a benefit period actually is

In Original Medicare, a benefit period begins the day you're admitted as an inpatient in a hospital or skilled nursing facility. It ends when you've gone 60 days in a row without any inpatient hospital care — and without skilled care in a SNF. If you go back into a hospital or SNF after that 60-day gap, a brand-new benefit period starts. A benefit period isn't a calendar year, and it isn't a single stay. It's a rolling window that opens with an inpatient admission and closes only after a long enough break in care.

One important federal rule: time in a SNF keeps a benefit period open only if the care there met Medicare's skilled level of care. Simply being in a nursing facility isn't enough — the care must qualify as skilled under Medicare's definition.

Why the deductible can hit twice in one year

For 2026, the Part A inpatient hospital deductible is $1,736, up from $1,676 in 2025. That deductible is owed for each benefit period — not once a year. Because there is no limit to the number of benefit periods you can have in a single year, it is entirely possible to owe the deductible more than once between January and December.

Here's a simple example of how that could happen. Suppose someone is admitted in February for a serious illness, is discharged, and recovers at home without any further inpatient or skilled SNF care. If they are hospitalized again in August — more than 60 days after their last inpatient or skilled day — a new benefit period begins, and the Part A deductible applies again.

The deductible covers your share of costs for the first 60 days of Medicare-covered inpatient hospital care in that benefit period. (People enrolled in a Medicare Advantage plan may instead be charged copayments during those first 60 days; the specifics depend on the plan.)

What happens after day 60

In Original Medicare for 2026, once you've paid the Part A deductible, inpatient hospital costs per benefit period work like this:

• Days 1–60: $0 per day after the deductible
• Days 61–90: $434 per day
• Days 91–150: $868 per day, but only if you choose to use lifetime reserve days
• After day 150: all costs are yours

Every person with Part A has a non-renewable lifetime reserve of 60 extra inpatient hospital days. Once you've used your 90 regular days in a benefit period, those reserve days are generally used automatically unless you file a written election with the hospital not to use them. Once spent, reserve days can never be renewed.

Each new benefit period renews your 90 regular inpatient hospital days and your 100 SNF days — but your lifetime reserve days are a lifetime bank, not a per-period one.

Skilled nursing facility costs

SNF care in Original Medicare for 2026 looks like this, per benefit period, after the Part A deductible:

• Days 1–20: $0 per day
• Days 21–100: $217 per day
• After day 100: all costs

Part A limits SNF coverage to 100 days in each benefit period. Helpful detail: if you already paid the Part A deductible for a hospital stay in the same benefit period, you don't pay it again for SNF care in that period.

Where Medigap fits in

If you have Original Medicare, a Medigap (Medicare Supplement) policy can help with these Part A costs. Every standardized Medigap plan letter shown on Medicare.gov's comparison chart — A, B, C, D, F, G, K, L, M, and N — covers Part A coinsurance and hospital costs for up to an additional 365 days after Medicare's hospital benefits are used up. The level of help with other costs varies by plan letter.

Original Medicare vs. Medicare Advantage: a neutral word

Hospital cost-sharing is one place where Original Medicare and Medicare Advantage work differently. Original Medicare uses the benefit-period deductible and daily coinsurance described above; a Medigap plan can fill in much of that cost-sharing, but you pay a separate Medigap premium and Part B works independently. Medicare Advantage plans bundle hospital, medical, and usually drug coverage with their own copay structures and provider networks, and they include an annual out-of-pocket maximum for in-network Part A and B services. Neither approach is universally "better" — the right fit depends on your health, budget, providers, and preferences.

A few dates and numbers to keep in mind

• Annual Open Enrollment for 2027 coverage runs October 15 – December 7, 2026, with changes effective January 1, 2027.
• The Part D out-of-pocket cap is $2,100 in 2026 and rises to $2,400 in 2027.
• The maximum Part D plan deductible for 2027 is $700, and the Part D base beneficiary premium (used to calculate the late-enrollment penalty) is $41.33.
• Social Security announced a 3.6% cost-of-living adjustment for benefits beginning January 2027.
• The 2027 Part B standard premium and deductible, and the 2027 IRMAA income brackets, have not yet been announced; CMS typically releases them in the fall.

If you have Medicaid or Extra Help

Since 2025, people with Medicaid or Extra Help have a monthly Special Enrollment Period to move to Original Medicare paired with a stand-alone Part D plan, or to switch stand-alone Part D plans. Full-benefit dual-eligible individuals can also enroll in an integrated Dual Eligible Special Needs Plan (D-SNP) in any month.
