Robert Chen paid his $1,736 Medicare Part A deductible in February 2026 after five days in the hospital with pneumonia. He went home, recovered, and assumed that was the year’s hospital deductible handled, the same way his old employer plan worked. In November, a cardiac event put him back in the hospital for ten days. The bill that followed included another $1,736 deductible, the exact same amount, for the exact same Medicare Part A coverage he thought he had already paid nine months earlier. Robert had not made a mistake, and neither had the hospital’s billing office. Original Medicare’s Part A deductible does not reset once a year like most private insurance. It resets every time a new benefit period begins, and a benefit period can start more than once in a single calendar year.

What actually starts and ends a Medicare benefit period

The Centers for Medicare & Medicaid Services (CMS), the federal agency that runs Medicare, defines a benefit period in its own published guidance this way: “A benefit period begins on the day you start getting inpatient hospital or skilled nursing facility care,” and it “ends when you stop getting skilled nursing facility care for 60 days in a row.” The same 60-day rule applies to inpatient hospital care. If you are readmitted after that 60-day gap closes, CMS is direct about what happens next: “a new benefit period will start,” and “you must pay the Part A deductible each time you start a new benefit period.” CMS adds one line that should end the confusion for good: this reset “could be multiple times in a calendar year.” Robert’s nine months of recovery between February and November cleared the 60-day gap easily, several times over, which is exactly why the second deductible was correct. One more wrinkle worth knowing before you count days yourself: time spent under observation status does not count toward starting a benefit period the same way an admitted inpatient stay does, even if it feels identical from the hospital bed.

The 2026 dollar figures, and what changes at day 60 and day 90

Inside a single benefit period, Medicare’s own 2026 cost sheet lays out exactly what a hospital stay costs. You pay the $1,736 deductible once at the start. Medicare then covers the first 60 days of that benefit period in full, with no daily charge. From day 61 through day 90, you pay $434 per day out of your own pocket. Past day 90, Medicare stops paying entirely unless you draw on what CMS calls lifetime reserve days, a pool of 60 extra days that cost $868 per day when used. Once every one of your 150 covered days inside a single benefit period runs out, you pay the full cost of every remaining day yourself. Skilled nursing facility stays run on the same benefit-period clock with their own separate numbers, covered in full here: the first 20 days cost nothing beyond the Part A deductible already paid for that benefit period, days 21 through 100 cost $217 per day, and every day after 100 is billed in full. Robert’s two stays, five days and ten days, never came close to any of these thresholds. A single stay that runs long enough to reach them is a different, much more expensive problem entirely.

Why the lifetime reserve days are the trap inside the trap

The name “lifetime reserve days” is literal, and it catches people who assume the pool refills the way the 60-day hospital stretch does. It does not. Every Medicare beneficiary gets exactly 60 lifetime reserve days to use across every hospital stay for the rest of their life, not 60 per benefit period and not 60 per year. If a benefit period runs past day 90 and you use, say, 20 lifetime reserve days to cover part of it, you have 40 left. Not 40 for this benefit period and a fresh 60 next time. Forty, period, for every future hospitalization you will ever have under Medicare. A beneficiary who burns through all 60 during one long illness has zero lifetime reserve days left for anything that happens years later, no matter how many new benefit periods start between now and then.

What actually closes this gap

Original Medicare has no yearly out-of-pocket maximum on Part A costs, which is part of why this benefit-period structure can compound so quickly for someone with more than one hospitalization in a year. A Medicare Supplement Insurance policy, commonly called Medigap, is built specifically to cover the gaps in Original Medicare’s own cost-sharing structure, including this one. Depending on the plan, Medigap coverage can pick up the Part A deductible, the day 61 through 90 coinsurance, and the lifetime reserve day coinsurance entirely, which would have made Robert’s second $1,736 charge a non-event instead of a surprise. Not every Medigap plan covers all of these gaps identically. Plan F and Plan G are typically the most complete, while Plan N leaves smaller per-visit copays in place. Comparing Plan G against Plan N by age and cost against your own hospitalization risk, rather than against price alone, is what actually closes this specific gap.

The number that should have been on Robert’s calendar

Robert’s real mistake was not a billing error. It was assuming a hospital deductible works the way every other deductible in his financial life works: once a year, done. Medicare’s benefit period counts days out of the hospital, not months on a calendar. Sixty days clear, and the meter resets completely, deductible included. Anyone managing Original Medicare with more than one health condition serious enough to risk hospitalization should treat that 60-day window as the number that actually matters, not January 1st. Robert paid $3,472 in Part A deductibles in a single year for two unrelated hospital stays, and Medicare’s own rules made both charges correct.

Day range in the benefit period	Inpatient hospital cost	Skilled nursing facility cost
Deductible, once per benefit period	$1,736	Covered by the same Part A deductible if it follows a qualifying hospital stay
Days 1 to 60 (hospital) / 1 to 20 (SNF)	$0 per day	$0 per day
Days 61 to 90 (hospital) / 21 to 100 (SNF)	$434 per day	$217 per day
Lifetime reserve days (hospital only, 60 total ever)	$868 per day	Not applicable
Beyond day 150 (hospital) / day 100 (SNF)	100% of costs	100% of costs

Frequently asked questions

Does the Medicare Part A deductible reset every year?

No. It resets every time a new benefit period starts, not once a year. A benefit period ends after you have gone 60 days in a row without inpatient hospital or skilled nursing facility care. If you are readmitted after that gap, you pay the $1,736 deductible again, even within the same calendar year.

How many benefit periods can you have in one year?

As many as your hospitalizations create. Each time you are readmitted after a 60-day gap with no inpatient care, a new benefit period begins and a new Part A deductible applies. There is no annual limit on how many benefit periods, or deductibles, you can have in a single year.

What are Medicare lifetime reserve days and how many do you get?

You get 60 lifetime reserve days total, for your entire life, not per benefit period or per year. They kick in after day 90 of a hospital stay within a single benefit period, cost $868 per day in 2026, and once used they never come back, even in a future benefit period.

Does Medigap cover the Part A deductible and benefit period gaps?

Some Medigap plans do. Plans F and G typically cover the Part A deductible along with the day 61 through 90 and lifetime reserve day coinsurance in full. Plan N leaves smaller copays in place. Coverage varies by plan letter, so confirm what your specific plan covers before assuming it handles a repeat deductible.

How much does a Skilled Nursing Facility stay cost under Medicare in 2026?

Nothing for the first 20 days of a benefit period, assuming you had a qualifying hospital stay first. Days 21 through 100 cost $217 per day out of pocket in 2026. After day 100 in that benefit period, Medicare stops paying and you cover the full daily cost yourself.
