Medicare Part A can feel like a puzzle, especially when you’re trying to figure out what’s actually covered and where your costs might spike. Here’s the straight answer: Medicare Part A covers inpatient hospital care, skilled nursing facility care, and critical access hospitals, but it comes with daily cost-sharing and strict limits that can leave you with hefty bills. No annual out-of-pocket maximum exists under Part A alone, which means costs can pile up fast if you have a long hospital stay.
Let’s break down exactly what those limits mean for your wallet and your coverage so you can plan ahead.
What Medicare Part A Actually Covers
Medicare Part A is your inpatient coverage. That means hospital stays, not doctor visits or outpatient care. It also covers skilled nursing facility stays if you qualify, and critical access hospitals in rural areas.

Most people pay $0 in premiums because they or their spouse worked 40+ quarters (10 years) in a Medicare-covered job. If you don’t have enough work history, you might pay up to $565 per month in 2026. But the premium is only part of the story. The real costs show up when you actually use it.
Breaking Down the 2026 Cost Structure
This is where it gets important. Medicare Part A uses what’s called a “benefit period” to track your costs. A benefit period starts the day you’re admitted to the hospital and ends 60 days after you’re discharged. If you’re readmitted within that window, it counts toward the same benefit period.
Here’s the cost breakdown:
- Deductible: $1,736 per benefit period. You pay this out of pocket before Medicare kicks in.
- Days 1-60 of hospital stay: Medicare covers 100% after you meet the deductible.
- Days 61-90: You pay $419 per day (coinsurance). Medicare covers the rest.
- Days 91+: You pay $838 per day from your lifetime reserve days, which are limited to 60 total days in your lifetime.
Once you use up your 60 lifetime reserve days, Medicare stops covering inpatient hospital care beyond day 90. That means you’re paying 100% of hospital costs out of pocket.
The Skilled Nursing Facility Limits
If you need skilled nursing care after a hospital stay (at least 3 days), Medicare Part A also covers that, but with limits.
Here’s how it breaks down:
- Days 1-20: Medicare covers 100% of approved costs.
- Days 21-100: You pay $209.50 per day in coinsurance (2026 amount).
- Day 101+: You pay everything out of pocket.
These limits reset each benefit period. If you’re discharged and readmitted within 60 days, you’re still in the same benefit period, so the costs continue to accumulate.
Why There’s No Annual Out-of-Pocket Maximum
Here’s the thing that surprises a lot of people: Medicare Part A doesn’t have an annual out-of-pocket maximum limit like commercial insurance does. That means theoretically, you could face unlimited costs if you have multiple hospital stays or a very long stay.
This is one of the biggest reasons EZ Access Insurance strongly recommends pairing Part A with supplemental coverage like Medigap (Medicare Supplement) or Medicare Advantage. Without it, extended hospital stays can drain your savings quickly.

Real-World Example: What a Hospital Stay Could Cost
Let’s say you’re hospitalized for 75 days due to a serious illness.
- Days 1-60: You pay $1,736 (deductible) + $0 for hospital costs = $1,736
- Days 61-75 (15 days): You pay 15 × $419 = $6,285
- Total out of pocket: $8,021
That’s just one benefit period. If you were hospitalized again within 60 days, you’d face another $1,736 deductible and the same cost structure all over again.
Now imagine a 120-day stay. After day 90, you’re either paying $838/day from your lifetime reserve (if you haven’t used them up) or 100% of costs. A long-term hospitalization can easily exceed $20,000+ out of pocket.
Understanding “Benefit Periods” and How They Reset
This catches a lot of people off guard. A benefit period isn’t a calendar year like you might think. It’s based on when you’re admitted and discharged.
Say you’re hospitalized January 15 and discharged February 10. Your benefit period ends 60 days after discharge, which is around April 10. If you’re admitted again on April 12, that’s a new benefit period with a new $1,736 deductible. The previous costs don’t carry over, but the new hospitalization starts from scratch.
This means if you have multiple hospital stays in a short window, you could pay multiple deductibles in a single year. Planning ahead with supplemental coverage is crucial.
Do You Need Supplemental Coverage?
Here’s our honest take: Medicare Part A alone leaves you exposed. If you’re on Original Medicare (Part A + Part B), you almost certainly need either a Medigap plan or Medicare Advantage to cap your costs.

Medigap plans (also called Medicare Supplement): These fill the gaps in Original Medicare. Plans like Medigap G or N cover the hospital deductible, the daily coinsurance for days 61-90, and even some or all costs after your lifetime reserve days run out. You’ll pay a monthly premium (usually $100-300), but you gain predictable, capped costs.

Medicare Advantage: These are all-in-one plans from private insurers that cover Part A and Part B benefits. They usually have lower premiums ($0-50/month), but they cap your out-of-pocket maximum annually. If you have a major hospitalization, you know exactly what your max cost will be.
Choosing between them depends on your health, budget, and preference for flexibility. If you’re not sure which is right for you, EZ Access Insurance can walk you through both options personalized to your situation.
Common Misconceptions About Part A Limits
Myth: “Medicare covers everything after 90 days.” False. After 90 days, you pay $838/day from a limited pool of 60 lifetime reserve days. Once those are gone, Medicare stops covering inpatient hospital care.
Myth: “The deductible resets every year.” False. It resets every benefit period, which is based on your admission and discharge dates, not the calendar.
Myth: “Part A is free, so I don’t need anything else.” False. Premiums are free for most people, but the out-of-pocket costs during actual care can be substantial without supplemental coverage.
How to Lower Your Part A Costs
1. Get supplemental coverage: This is the biggest cost reducer. Medigap or Medicare Advantage caps your exposure.
2. Understand your benefit period: Know when it ends so you don’t accidentally trigger a new deductible.
3. Use in-network facilities (if on Medicare Advantage): Staying in-network keeps you in lower cost-sharing tiers.
4. Appeal denials: Sometimes Medicare denies coverage. Don’t accept the first no. File an appeal or ask EZ Access Insurance to help you navigate the process.
5. Review your coverage annually: During Open Enrollment (October 15 – December 7), you can switch plans if your needs change or if better options are available.
Looking Ahead: Planning for Part A Costs
Don’t wait until you’re hospitalized to figure this out. Now is the time to understand your coverage, identify gaps, and add supplemental coverage if you don’t have it.

Frequently Asked Questions
Does Medicare Part A have an out-of-pocket maximum?
No. Original Medicare Part A alone does not have an annual out-of-pocket maximum. Costs can accumulate without limit, especially for extended hospital stays. This is why supplemental coverage (Medigap) or Medicare Advantage is strongly recommended. Medicare Advantage plans do have an out-of-pocket maximum, typically $7,550-$8,000 in 2026.
What happens after my 60 lifetime reserve days run out?
Once you exhaust your 60 lifetime reserve days, Medicare no longer covers any inpatient hospital care beyond day 90 of a benefit period. You would pay 100% of hospital costs out of pocket. This is another critical reason to have Medigap coverage, which covers these costs after the lifetime reserve days are exhausted.
Can I have multiple benefit periods in one year?
Yes. Each hospital admission starts a new benefit period if you’ve been out of the hospital for 60 days or more. If you’re hospitalized twice with a 60+ day gap between discharges, you’ll face two separate $1,736 deductibles in the same calendar year. This is possible and does happen.
Is the Part A deductible the same every year?
No. The Part A deductible increases annually. In 2026, it’s $1,736. Check the Centers for Medicare & Medicaid Services (CMS) website each year for updates, or ask EZ Access Insurance during your annual review.
