Part A has a deductible you pay once per benefit period, not per hospital stay

Medicare Part A covers inpatient hospital care, skilled nursing facility care, hospice, and some home health services. When you use any of these services, you pay a deductible — a set dollar amount you cover before Medicare starts paying its share. For 2024, that deductible is $1,676 per benefit period. A benefit period starts the day you enter the hospital and ends 60 days after you leave without returning.

The key thing to understand: you pay this deductible once per benefit period, not once per hospital stay. If you go into the hospital, get discharged, and return within 60 days, you do not pay the deductible again. But if you stay out for 61 days or more and then return, a new benefit period begins and you owe the deductible a second time.

After you meet the deductible, Medicare covers the full cost of your hospital stay for days 1 through 60 of each benefit period. Starting on day 61, you pay a coinsurance amount — $419 per day in 2024 — for days 61 through 90. If you need to stay longer than 90 days, you can use your "lifetime reserve days," which are 60 additional days Medicare will help cover, though you pay $838 per day in coinsurance for those.

Key Takeaways

  • You pay the Part A deductible ($1,676 in 2024) once per benefit period, which runs from hospital admission through 60 days after discharge.
  • After you pay the deductible, Medicare covers all hospital costs for the first 60 days of your stay with no additional out-of-pocket charges.
  • Days 61 through 90 require you to pay coinsurance ($419 per day in 2024), and days beyond 90 use lifetime reserve days at a higher coinsurance rate ($838 per day).
  • The deductible amount changes each year, so check your Medicare materials or Medicare.gov for the current year's figure.
  • If you are readmitted to the hospital more than 60 days after your previous discharge, a new benefit period starts and you owe the deductible again.

How the deductible works across a full hospital stay

Imagine you enter the hospital on January 15 and stay for 45 days, leaving on February 28. You pay the $1,676 deductible. Medicare then covers the remaining cost of your stay at no charge to you. You leave the hospital and do not return. On May 1 — more than 60 days later — you are admitted again. This is a new benefit period, so you owe the deductible a second time.

Now imagine a different scenario: you enter the hospital on January 15 and stay for 45 days. You pay the deductible. You go home, but on March 10 — only 40 days after discharge — you are readmitted. You do not pay the deductible again because you are still in the same benefit period. Medicare continues to cover your care at no charge (assuming you have not yet reached day 61 of your total stay).

The benefit period is the organizing principle. It is not about how many times you enter the hospital; it is about the calendar span from admission through 60 days after your last discharge in that sequence.

What happens if your hospital stay extends beyond 60 days

If you need to stay in the hospital longer than 60 days in a single benefit period, you enter a coinsurance zone. From day 61 through day 90, you pay $419 per day (in 2024) and Medicare covers the rest. This is different from the deductible: you are not paying the full cost, just a daily share.

If your stay goes beyond 90 days, you can draw on your lifetime reserve days. Medicare gives you 60 of these days total for your entire life — not per year, but total. When you use a reserve day, you pay $838 per day (in 2024) and Medicare covers the rest. Once you exhaust your 60 lifetime reserve days, you pay all costs yourself unless you have supplemental insurance.

Most people never need to stay in the hospital for 90 consecutive days, so lifetime reserve days are rarely used. But they exist as a safety net for very long stays.

The deductible changes every year

Medicare adjusts the Part A deductible each January based on inflation and changes in hospital costs. The 2024 deductible is $1,676, but this amount will likely be different in 2025 and beyond. The coinsurance amounts for days 61–90 and the lifetime reserve day rate also change annually.

You can find the current year's deductible and coinsurance amounts on Medicare.gov, or you can call Medicare at 1-800-MEDICARE (1-800-633-4227) to ask. Your Medicare Summary Notice, which you receive each year, also lists these figures.

Supplemental insurance can cover the deductible and coinsurance

Many people buy a Medigap policy (also called supplemental insurance) that covers some or all of the Part A deductible and coinsurance amounts. Depending on which Medigap plan you choose, the policy may pay your $1,676 deductible, your daily coinsurance on days 61–90, or both.

Medigap is sold by private insurance companies, not by Medicare. It costs extra each month, but for people who expect to use the hospital, it can reduce out-of-pocket costs significantly. If you are interested in Medigap, you can compare plans on Medicare.gov or contact insurance companies directly.

If you are in a Medicare Advantage plan instead of Original Medicare, your plan has its own deductible and coinsurance rules, which may be different from Part A's standard amounts. Check your plan documents or call your plan to learn what you would pay.

Skilled nursing facility care also uses the Part A deductible

The Part A deductible applies not only to hospital stays but also to skilled nursing facility (SNF) care — care you receive in a nursing home after a hospital stay. If you are admitted to a SNF within 30 days of leaving the hospital, you use the same benefit period and the same deductible you already paid.

For SNF care, after you pay the deductible, Medicare covers all costs for days 1 through 20. From day 21 through day 100, you pay a coinsurance amount ($209.50 per day in 2024) and Medicare covers the rest. After day 100, you pay all costs yourself unless you have supplemental insurance.

This is why the benefit period matters: if you spend 30 days in the hospital and then move to a SNF, those days count together toward your 60-day benefit period clock. The deductible you paid in the hospital does not need to be paid again for the SNF stay.

Frequently Asked Questions

Do I pay the Part A deductible every time I go to the hospital?

No. You pay it once per benefit period. A benefit period runs from the day you enter the hospital through 60 days after you leave. If you are readmitted within those 60 days, you do not pay the deductible again. If you stay out for 61 days or longer and then return, a new benefit period begins and you owe the deductible again.

What is the difference between the deductible and coinsurance?

The deductible is a flat amount ($1,676 in 2024) you pay before Medicare starts covering costs. Coinsurance is a daily amount you pay for certain days of your stay — for example, $419 per day for days 61–90. After you pay the deductible, Medicare covers your full hospital bill for days 1–60, but you share the cost on days 61 and beyond.

Can Medigap insurance pay my Part A deductible?

Yes. Many Medigap plans cover the Part A deductible and coinsurance. The specific coverage depends on which plan you choose. Medigap is optional and costs extra each month, but it can reduce your out-of-pocket costs if you use hospital or skilled nursing care.

What happens if I stay in the hospital for more than 90 days?

After 90 days, you can use your lifetime reserve days — 60 additional days Medicare will help cover. You pay $838 per day (in 2024) for each reserve day used. Once you exhaust your 60 lifetime reserve days, you pay all remaining costs yourself unless you have supplemental insurance.

Does the Part A deductible explore to doctor visits or outpatient care?

No. The Part A deductible applies only to inpatient hospital stays, skilled nursing facility care, hospice, and some home health services. Doctor visits and outpatient care are covered under Part B, which has its own separate deductible.
