Yes, Most Medigap Plans Cover Hospital Copays — But Not All of Them
Most Medicare supplement plans will cover your hospital stay copays, and the better ones cover them completely. That’s actually one of the biggest reasons people buy Medigap in the first place. But the details matter more than you’d think, and the wrong plan can leave you stuck with bills you weren’t expecting.
Here’s how it works. Original Medicare (Parts A and B) covers hospital stays, but it doesn’t pay 100% of everything. There are deductibles, daily copays, and lifetime limits built into the structure. Medigap exists to fill those gaps. Depending on which plan you choose, it fills them partially or almost completely.
I’ve talked to a lot of people who assumed their Medigap plan “covered everything hospital-related.” Some of them were right. Others were in for a surprise when they got the bill. Let me break down exactly what you’re looking at.
How Medicare Structures Hospital Costs (And Where the Gaps Are)
Before you can understand what Medigap covers, you need to understand what Medicare charges. Part A is your hospital insurance, and it doesn’t work like a simple copay system. It uses something called benefit periods, which trips people up constantly.
A benefit period starts the day you’re admitted to a hospital and ends after you’ve been out of the hospital (or a skilled nursing facility) for 60 consecutive days. Each benefit period has its own deductible and its own set of daily copays for longer stays.
For 2026, here’s what Part A actually charges you:
| Length of Hospital Stay | What Medicare Charges You |
|---|---|
| Days 1-60 | $1,676 deductible per benefit period (no daily copay) |
| Days 61-90 | $419 per day |
| Days 91-150 (lifetime reserve days) | $838 per day |
| Beyond 150 days | You pay 100% of all costs |
Most people never stay past day 60 in a single hospitalization, so the daily copays for days 61-90 don’t come up often. But that 2026 Part A deductible of $1,676 hits every single benefit period, not just once a year. If you’re hospitalized twice in a year with more than 60 days between stays, you owe that deductible twice. That’s the part that genuinely catches people off guard.
Part B has its own deductible for outpatient services. The 2026 Part B deductible is $257, and after that Medicare covers 80% of approved outpatient costs. You’re responsible for the remaining 20% with no cap unless you have Medigap.
Which Medigap Plans Actually Cover Hospital Copays
This is where you need to pay attention, because not every Medigap plan covers the same things. Let me give you the honest breakdown.
| Medigap Plan | Part A Deductible | Part A Daily Copays (Days 61-90) | Part B Coinsurance (20%) | Part B Deductible |
|---|---|---|---|---|
| Plan G | Covered 100% | Covered 100% | Covered 100% | Not covered |
| Plan N | Covered 100% | Covered 100% | Covered (with copays up to $20 office / $50 ER) | Not covered |
| Plan F | Covered 100% | Covered 100% | Covered 100% | Covered 100% |
| Plan K | 50% covered | 50% covered | 50% covered | Not covered |
| Plan L | 75% covered | 75% covered | 75% covered | Not covered |
| Plan A | Not covered | Covered 100% | Covered 100% | Not covered |
Plan F was the gold standard for years, but it’s no longer available to people who became eligible for Medicare after January 1, 2020. If you turned 65 before 2020, you can still buy it. If you didn’t, Plan G is now the most complete option available to you, and honestly, it’s the one I’d recommend for most people.
Plan G covers the 2026 Part A deductible of $1,676, all daily hospital copays, and the Part B 20% coinsurance. The only thing it doesn’t cover is the 2026 Part B deductible of $257. That’s $257 once a year out of pocket. After that, you’re essentially protected from any major cost exposure for both hospital stays and outpatient care.
Plan N is a solid second option if you’re generally healthy and want lower monthly premiums. You’ll pay a copay of up to $20 for office visits and up to $50 for emergency room visits that don’t result in an inpatient admission. Hospital stays themselves are still well covered under Plan N.
The Misconception That Trips Up a Lot of People
Here’s the mistake I see more than any other: people confuse “hospital stay” with “inpatient hospital stay.” They’re not always the same thing, and Medicare’s rules on this are genuinely maddening.
When you’re admitted to a hospital, you might be placed under “observation status” instead of being formally admitted as an inpatient. This happens more than you’d think, sometimes even when you’re staying overnight. Under observation status, you’re technically an outpatient. That means Part B covers your care, not Part A, and the cost structure is completely different.
Why does this matter? A few reasons. First, your Medigap plan’s hospital coverage is tied to Part A. If you’re under observation, Part A isn’t paying, so the benefit works differently. Second, and this is the one that really stings, if you go from the hospital to a skilled nursing facility under observation status, Medicare won’t cover your skilled nursing stay at all. Part A requires a three-day qualifying inpatient stay before it kicks in for skilled nursing. Observation days don’t count.
In my experience, people find out about this rule after the fact, when they’re already in the skilled nursing facility looking at a bill for thousands of dollars. The hospital generally won’t tell you proactively whether you’re inpatient or under observation. You have to ask. Specifically ask: “Am I formally admitted as an inpatient, or am I under observation status?” Get a clear answer in writing if you can.
This isn’t a Medigap problem, it’s a Medicare problem. But knowing it exists means you can ask the right questions and protect yourself.
What Plan G Actually Costs and Whether It’s Worth It
Plan G premiums vary significantly depending on your age, state, and the insurance company. At age 65, you’re typically looking at somewhere between $100 and $200 per month. A 65-year-old in Ohio might pay around $115 to $145 per month through a reputable carrier. In a higher-cost state like New York, that same person could pay $250 or more because New York has community rating rules that drive prices up.
Is it worth it? For most people, yes. Here’s the math for a simple scenario: if you have one hospital admission in a year, you’ve already gotten $1,676 worth of coverage from Plan G just on the Part A deductible alone. Add in any outpatient care, specialist visits, or procedures where Medicare’s 20% adds up, and Plan G’s value compounds quickly.
The people who might not need Plan G are those who are genuinely healthy, rarely see doctors, and have significant savings they’re comfortable using to cover unexpected medical costs. For those folks, Plan N or even a high-deductible Plan G can make sense. But if you’re asking me whether the average 67-year-old should buy protection against hospital copays, the answer is yes. The risk of one bad hospitalization without it is too high to justify saving $80 a month on premiums.
One more thing worth mentioning: if you’re already past your initial enrollment window, you may face medical underwriting to qualify for Plan G, which means insurers can deny you or charge more based on your health history. The best time to buy is when you first become eligible for Medicare, when you have guaranteed issue rights and can’t be turned down.
Bottom Line
Plan G is the right call for most people who want real protection against hospital stay costs. It covers the Part A deductible per benefit period, all daily hospital copays, and the Part B 20% coinsurance, leaving only the $257 annual Part B deductible on your plate. Buy it when you first enroll in Medicare, compare prices from at least three carriers in your state, and ask your hospital directly whether you’re admitted as an inpatient or under observation any time you end up in the emergency room.
Frequently Asked Questions
Does Medigap cover the Part A deductible every time I’m hospitalized?
Yes, if you have Plan G, Plan F, or Plan N, your Medigap plan covers the Part A deductible each time a new benefit period begins. Since a new benefit period starts after you’ve been out of the hospital for 60 consecutive days, you could theoretically owe this deductible more than once in a year if you have multiple hospitalizations with 60+ days between them. That’s exactly why having coverage for it matters.
Will Medigap cover me for a long hospital stay that goes past 60 days?
Yes. Plan G, Plan F, and Plan N all cover the daily copays for days 61 through 90, which are $419 per day in 2026. They also cover the lifetime reserve days (days 91-150), which cost $838 per day without coverage. Stays beyond 150 days are not covered by Medicare at all, and most Medigap plans don’t cover that either, though some plans offer a limited daily hospital benefit for extended stays.
I’m on a Medicare Advantage plan. Does any of this apply to me?
No. Medigap plans only work with Original Medicare. If you’re on Medicare Advantage, you can’t use a Medigap plan. Your hospital costs under Medicare Advantage depend entirely on your specific plan’s copays and out-of-pocket maximums, which vary by insurer and plan. If you want the Medigap protections described here, you’d need to switch back to Original Medicare first.
Can I buy Plan G if I’m already sick or have pre-existing conditions?
It depends on when you’re applying. During your initial Medigap open enrollment period, which starts when you’re 65 and enrolled in Part B, you have guaranteed issue rights and can’t be turned down for any plan. Outside of that window, most states allow insurers to use medical underwriting, meaning they can decline you or charge higher premiums based on your health. A few states, including New York, Connecticut, and Massachusetts, have stronger consumer protections that allow year-round enrollment regardless of health status.
