Most people pay nothing for Medicare Part A. If you or your spouse paid Medicare taxes for at least 10 years (40 quarters), your monthly premium is $0. You still owe a $1,676 deductible each time you’re admitted to the hospital in 2025, plus coinsurance if your stay runs long, but the premium itself is free for roughly 99% of enrollees.
If you don’t qualify for premium-free Part A, you’ll pay either $285 or $518 per month in 2025 depending on your work history. Here’s a full breakdown of every cost you could face.
Monthly Premiums in 2025
Your Part A premium depends entirely on how long you or your spouse worked and paid Medicare taxes:
- 40+ quarters of coverage (10+ years): $0 per month
- 30–39 quarters of coverage: $285 per month
- Fewer than 30 quarters: $518 per month
A “quarter of coverage” is a three-month period during which you earned enough to receive a work credit from Social Security. You can also qualify through your spouse’s work history. If your spouse has 30 or more quarters, you’re eligible for the reduced $285 rate even if you personally have little or no work history. These premiums went up slightly from 2024, when the reduced rate was $278 and the full rate was $505.
The Hospital Deductible
Even with premium-free Part A, you pay a deductible every time you’re admitted to the hospital. In 2025, that deductible is $1,676, up from $1,632 in 2024. This covers the first 60 days of each hospital stay. If you’re discharged and readmitted within 60 days, it counts as the same “benefit period” and you don’t owe the deductible again. But if more than 60 days pass between hospital stays, a new benefit period starts and you pay the full deductible again.
There’s no annual cap on how many times you can owe this deductible. Someone hospitalized twice in a year with a gap between stays would pay $1,676 twice.
Costs for Longer Hospital Stays
Your deductible covers days 1 through 60 with no additional daily charge. After that, coinsurance kicks in and climbs steeply:
- Days 61–90: $434 per day
- Days 91–150: $868 per day, drawing from your 60 lifetime reserve days
Lifetime reserve days are exactly what they sound like: a one-time bank of 60 extra days that Medicare provides over your entire lifetime. Once you use them, they don’t renew. A 30-day stay beyond day 90 would cost you $26,040 in coinsurance alone while burning through half your lifetime reserve. After all 150 days (90 standard plus 60 reserve) are exhausted, Medicare stops covering hospital costs entirely for that benefit period.
Skilled Nursing Facility Costs
Part A covers care in a skilled nursing facility after a qualifying hospital stay of at least three days. The first 20 days are fully covered with no coinsurance. Starting on day 21, you pay $217 per day through day 100. After day 100, Medicare coverage ends and you’re responsible for the full cost.
This coinsurance adds up quickly. A stay lasting the full 100 days means 80 days of coinsurance at $217, totaling $17,360 out of pocket. Many people use supplemental insurance (Medigap) specifically to cover this gap.
Hospice and Blood Costs
Part A covers hospice care with minimal out-of-pocket costs. You pay a copayment of up to $5 for each outpatient prescription related to pain and symptom management. If you need inpatient respite care (short-term stays that give your caregiver a break), you pay 5% of the Medicare-approved amount, capped at the inpatient hospital deductible for the year.
For blood, Part A requires you to cover the cost of the first three pints you receive in a calendar year. You can avoid this charge if you or someone else donates blood to replace it. After those first three pints, Part A covers additional blood at no cost to you.
Late Enrollment Penalties
If you have to buy Part A (because you don’t qualify for it premium-free) and you don’t sign up when you’re first eligible, your monthly premium increases by 10%. This penalty lasts for twice the number of years you went without coverage. So if you delayed enrollment by two years, you’d pay the higher premium for four years before it drops back to the standard rate.
This penalty only applies to people who must pay a Part A premium. If you qualify for premium-free Part A, there’s no penalty for late enrollment, though you may miss out on coverage during the gap.
What Most People Actually Pay
For the typical Medicare beneficiary with 10 or more years of work history, the real cost of Part A is the $1,676 hospital deductible per benefit period, plus coinsurance if a stay exceeds 60 days. The monthly premium is zero. Routine doctor visits, lab work, and outpatient care fall under Part B, which has its own separate premium and costs.
If you’re concerned about the coinsurance for long hospital or nursing facility stays, a Medigap policy (Medicare Supplement Insurance) can cover most or all of those daily charges. The tradeoff is an additional monthly premium for the supplement plan, but it puts a ceiling on what a serious hospitalization could cost you.
