What Medicare Actually Pays for Skilled Nursing Facility Care
Most people are shocked when they see the bill after a skilled nursing facility stay. They assumed Medicare covered it. And in a sense it does — but only partially, and only under conditions that are stricter than most people realize.
Here’s how the benefit period breaks down under Original Medicare in 2026. For days 1 through 20, Medicare covers 100% of the cost. That sounds great until you hit day 21. Starting on day 21, you’re on the hook for a coinsurance amount of $209.50 per day in 2026. That’s not a typo. Every single day from day 21 through day 100, you owe $209.50 out of pocket. After day 100, Medicare pays nothing at all.
That means a 60-day skilled nursing stay — which is not unusual after a hip replacement or stroke — could cost you over $8,000 in coinsurance alone. A 90-day stay pushes that figure past $14,600. And this is on top of your Part A deductible of $1,676 per benefit period in 2026, which you likely already paid when you were hospitalized.
This is exactly the gap that Medigap was designed to fill. But here’s what a lot of people don’t fully understand: not every Medicare supplement plan covers the skilled nursing facility coinsurance. The coverage depends entirely on which plan you buy.
Which Medigap Plans Actually Cover the SNF Coinsurance
Let me be direct about this. If skilled nursing facility coverage matters to you — and it should — then you need to pick a Medigap plan that explicitly covers the SNF coinsurance. Several plans do. A few don’t. And one popular plan is more limited than people expect.
Here’s a quick breakdown of how the major standardized Medigap plans handle SNF coinsurance coverage:
| Medigap Plan | SNF Coinsurance (Days 21-100) | Part A Deductible | Part B Deductible |
|---|---|---|---|
| Plan G | 100% covered | 100% covered | Not covered |
| Plan N | 100% covered | 100% covered | Not covered |
| Plan F (grandfathered) | 100% covered | 100% covered | 100% covered |
| Plan K | 50% covered | 50% covered | Not covered |
| Plan L | 75% covered | 75% covered | Not covered |
| Plan A | Not covered | Not covered | Not covered |
| Plan B | Not covered | 100% covered | Not covered |
For most people newly enrolling in Medicare in 2026, Plan G is the gold standard. It covers the SNF coinsurance in full, covers the Part A deductible, and the only thing it doesn’t cover is the Part B deductible (which is $257 in 2026 — a small price to pay for that level of protection). Plan G premiums typically run $100 to $200 per month at age 65, depending on your state and which insurer you use. A 65-year-old woman in Ohio might pay $115 to $140 a month with a reputable carrier. That’s a reasonable trade-off for coverage that can save you tens of thousands of dollars in a bad year.
Plan N is worth a look if you’re in good health and want lower premiums. It also covers the SNF coinsurance fully, but you’ll pay up to $20 per doctor visit and up to $50 for emergency room visits. It’s a better fit for someone who rarely sees specialists and wants to save $20-$40 a month on premiums.
The Qualification Rules Most People Miss
Here’s where it gets frustrating. Even if you have the best Medigap plan in the world, your insurance can only pay what Medicare approves. And Medicare’s rules for qualifying for skilled nursing facility coverage are strict enough that a lot of people don’t actually qualify — even when they think they will.
To qualify for Medicare’s SNF benefit, three conditions must be met. First, you must have had a qualifying hospital stay of at least three consecutive days as an inpatient (not under observation status). Second, the SNF admission must be for a condition that was treated during that qualifying hospital stay. Third, you must need skilled care — meaning daily skilled nursing or therapy services — not just custodial care like help with bathing and eating.
The observation status issue is the one that catches people off guard most often. Hospitals sometimes keep patients under “observation” rather than admitting them as inpatients. From the patient’s perspective, everything looks the same: you’re in a hospital bed, wearing a gown, getting IV fluids. But under Medicare’s rules, observation days don’t count toward the three-day qualifying stay. That means if you were in the hospital for four days under observation and then transferred to a skilled nursing facility, Medicare won’t cover your SNF stay at all — and neither will your Medigap plan, because Medigap only fills gaps in Medicare-approved costs.
I’ve seen this happen to people who were genuinely blindsided. If you’re ever admitted to a hospital and you’re not sure of your status, ask directly: “Am I admitted as an inpatient, or am I under observation status?” It’s a question you have every right to ask.
The Common Misconception That Costs People Real Money
The single biggest mistake I see is people confusing skilled nursing facility care with long-term care. They are not the same thing, and Medigap does not cover long-term care. Not even close.
Medicare’s SNF benefit covers short-term, medically necessary skilled care after a qualifying hospital stay. We’re talking about post-surgical rehabilitation, wound care, IV antibiotics, physical therapy after a stroke — things that require licensed nurses or therapists on a daily basis. Once you plateau in your recovery and no longer need skilled services, Medicare stops paying. That’s true even if you still need help walking, dressing, or eating. That kind of ongoing personal assistance is classified as custodial care, and it’s excluded from Medicare and Medigap entirely.
Long-term custodial care is expensive. A private room in a nursing home in many states runs $8,000 to $10,000 per month or more. Medigap will never cover that. If long-term care is a concern — and statistically it should be, because about 70% of people turning 65 will need some form of it — you need to be looking at long-term care insurance or hybrid life/LTC policies, not Medigap. Those are separate products entirely.
I bring this up because I’ve talked to people who thought their Plan G was a safety net for nursing home care. It isn’t. And finding that out at age 80 when you need placement is a terrible time to discover the gap.
How SNF Coverage Works in Practice: A Real Example
Let me walk through a realistic scenario so this stops being abstract. Take a 72-year-old man in Florida who falls and breaks his hip. He’s admitted to the hospital as an inpatient (not observation) and has surgery. He stays in the hospital for four days, then gets transferred to a skilled nursing facility for rehabilitation.
Here’s what the cost picture looks like with and without Plan G:
| Expense | Without Medigap | With Plan G |
|---|---|---|
| Part A deductible (2026) | $1,676 | $0 |
| SNF days 1-20 | $0 | $0 |
| SNF days 21-45 (25 days at $209.50/day) | $5,237.50 | $0 |
| Total out-of-pocket | $6,913.50 | $0 (after Plan G premium) |
A 45-day skilled nursing stay after a hip replacement is not unusual. That’s a $6,900 exposure without Medigap, covered almost entirely by Plan G. Even at $150/month in premiums, that’s $1,800 a year — and one SNF stay wipes out years of premium costs in a single event.
Bottom Line
If you’re choosing a Medigap plan and skilled nursing facility coverage matters to you (it should), Plan G is the right choice for most people. It gives you full SNF coinsurance coverage, strong hospitalization protection, and predictable costs, all for a premium that most people find manageable. Don’t let the slightly lower premiums of Plan K or Plan L talk you into partial coverage on something this expensive — the math doesn’t work out in your favor when you actually need a SNF stay.
Frequently Asked Questions
Does Medigap cover all 100 days of a skilled nursing facility stay?
No. Medicare and Medigap together cover days 1 through 100, but the structure is different for each phase. Medicare pays 100% for days 1-20. For days 21-100, plans like Plan G and Plan N cover the daily coinsurance ($209.50 in 2026) so you pay nothing. After day 100, Medicare pays nothing and neither does Medigap. A skilled nursing facility stay that extends past 100 days is your full financial responsibility unless you have a separate long-term care policy.
What if I was in the hospital under observation status — does Medigap still help?
Only if Medicare approves the SNF stay in the first place. If your hospital time was spent under observation rather than as a formal inpatient admission, you likely won’t qualify for Medicare’s SNF benefit at all. Medigap fills gaps in Medicare-covered services, so if Medicare doesn’t cover the SNF stay, Medigap won’t either. This is one reason to always confirm your admission status while you’re still in the hospital.
Will Medigap cover a nursing home stay if I just need help with daily activities?
No. This is custodial care, not skilled care, and it’s not covered by Medicare or any Medigap plan. Medicare’s SNF benefit only applies when you need daily skilled nursing or therapy services. Once your condition stabilizes and you no longer require that level of care, Medicare stops covering the stay — regardless of whether you’re still in the facility.
Is Plan G really worth the higher premium compared to Plan N for SNF coverage?
Both Plan G and Plan N cover the SNF coinsurance in full, so on that specific benefit they’re equal. The difference is that Plan N has copays for doctor and ER visits. If you’re healthy and rarely see specialists, Plan N can save you $20-$40 a month in premiums. But if you’re a frequent healthcare user or want zero surprises, Plan G’s predictability is worth the extra cost. For SNF coverage specifically, either plan will protect you equally well.
