Medicare Part A, hospital coverage
Last reviewed June 11, 20266 min readBy the Goodsurance editorial team Reviewed by the Goodsurance editorial team
Part A is the part of Medicare most people never think about until they are admitted to a hospital. It is the hospital-insurance half of Original Medicare, and for most people it arrives quietly and costs nothing in monthly premium: if you or your spouse worked and paid Medicare taxes for at least 10 years, your Part A premium is $0. What it covers is narrower than the word "hospital" suggests, and the gaps, observation status and long-term care, are where people get surprised.
1What Part A covers
Part A pays for care when you are formally admitted as an inpatient, plus a few related settings:
- Inpatient hospital stays: your room, nursing, meals, and the drugs and services you receive as an admitted patient.
- Skilled nursing facility care: short-term, after a qualifying hospital stay, when you need skilled care like rehabilitation or wound care. This is not the same as long-term nursing-home care.
- Hospice care: comfort-focused care for a terminal illness.
- Some home health care: limited and specific, generally when you are homebound and need skilled care.
The thread connecting all of these is skilled and short-term. Part A is built for episodes: you get sick, you get treated, you recover. It is not built for the slow, ongoing kind of care someone might need for years, and that distinction matters more than almost anything else here.
Inpatient hospital. Part A covers a semi-private room, general nursing, meals, and the drugs and services delivered while you are admitted. It does not cover a private room unless medically necessary, private-duty nursing, or the television and phone charges some hospitals still bill separately.
Skilled nursing facility (SNF). Part A covers an SNF stay only after a qualifying inpatient hospital stay, and only while you genuinely need skilled care, the kind that requires a licensed professional, such as physical therapy after a hip replacement or IV antibiotics. The moment your needs become custodial, help with bathing or dressing rather than skilled treatment, Part A coverage ends, even if you are still in the same bed.
Hospice. For a terminal illness a doctor certifies, Part A covers hospice care focused on comfort rather than cure: pain management, nursing, counseling, and support for the family. It is one of the most comprehensive things Part A does, and one of the least understood until a family needs it.
Home health. Narrow and specific. Part A (with Part B) can cover part-time skilled nursing or therapy at home if you are homebound and a doctor orders it. It does not cover full-time care, meal delivery, or general help around the house.
2The observation-status trap
This is the single most important thing here that most people have never heard of. Part A coverage for a skilled nursing facility stay requires a qualifying inpatient hospital stay, generally three days as a formally admitted inpatient. Here is the trap: a hospital can keep you for several days under "observation status" rather than admitting you. You are in a hospital bed, you are being treated, it looks and feels like admission, but technically you are an outpatient under observation, which falls under Part B, not Part A.
If you are then discharged to a skilled nursing facility for rehab, those observation days do not count toward the three-day requirement, and Part A may not cover the SNF stay at all. People have been handed large nursing-home bills they never saw coming because of a status distinction no one explained at the time.
The protection is simple: if you or a family member is in the hospital for more than a night, ask directly whether you are admitted as an inpatient or under observation. Hospitals are required to tell you. If you are under observation and a nursing-home stay may follow, that is the moment to have the conversation, not after discharge.
Nights "under observation" look identical from the bed but bill under Part B and do not count toward the 3-day inpatient stay a skilled nursing facility requires, so the SNF benefit can vanish. Ask whether you are admitted or under observation.
3What it costs when you actually use it
A $0 premium does not mean $0 when you are admitted. Part A has cost-sharing, and it works per "benefit period" rather than per year, which trips people up.
For an inpatient hospital stay, you pay a deductible of $1,736 per benefit period in 2026. A benefit period starts the day you are admitted and ends after you have been out for 60 days straight. If you are admitted again after that, a new benefit period begins, and so does another deductible, so a rough year with multiple separate hospitalizations can mean paying it more than once.
The daily coinsurance is where a long stay gets expensive. The first 60 days, the deductible is all you owe. After that, $434 a day applies for days 61 through 90. Beyond 90 days in a single benefit period, you draw on a one-time bank of "lifetime reserve days," 60 across your entire life, each charged at $868 a day in 2026. Once those are gone, they are gone, and you pay all costs.
Skilled nursing has its own ladder. The first 20 days of a covered SNF stay are fully paid; from day 21 you owe $217 a day in 2026, and after day 100 the stay is entirely on you.
Most stays never reach these thresholds. But the structure is why a serious year can produce real out-of-pocket exposure, and a large part of why people pair Original Medicare with a Medigap supplement, which is built to absorb exactly these Part A costs.

4The buy-in, if you did not earn premium-free Part A
A smaller group did not accumulate enough work credits, theirs or a spouse's, to get Part A for free. They can still get it by paying a monthly premium, and the amount depends on how many credits they earned: a lower premium of $311 a month in 2026 for those who worked 30 to 39 quarters, and a higher $565 a month for those with fewer than 30.
It is a real cost, and it interacts with other rules in ways that are easy to get wrong, for instance whether it makes more sense to take premium Part A or look at a different path entirely. This is one of the situations where talking through the math with a licensed agent before you enroll can save a meaningful amount.
5The gap that defines Part A: long-term care
Here is the single most important thing to understand, because the misunderstanding is so common and so costly. Part A does not pay for long-term custodial care. If someone needs help with everyday activities like bathing, dressing, or eating over months or years, and does not need skilled medical care, Medicare does not cover that stay. People assume it does, plan around an assumption that is not true, and find out at the worst possible moment.
The line is genuinely confusing. Part A will cover a skilled nursing facility for rehab after a hospital stay, for a limited time, while skilled care is needed. It will not cover the same facility, or the same bed, once the need becomes custodial. The building does not change; the type of care does, and Medicare follows the type of care, not the address.
The path that does cover long-term custodial care is Medicaid, which has its own income and asset rules and is a separate system from Medicare. Qualifying often means spending down assets to a limit, which works far better started early than in a crisis. There is also standalone long-term care insurance, bought ahead of time specifically for this gap. Neither is a Part A feature, and that is exactly the point: if long-term care is a real concern, it is a separate plan you make on purpose, not something Medicare quietly has covered.

Is Medicare Part A free?
Medicare Part A is premium-free for most people, but it is not entirely free.
If you or your spouse paid Medicare taxes for at least 40 quarters, about 10 years of work, you pay no monthly premium for Part A in 2026. If you worked 30 to 39 quarters, the Part A premium is $311 per month in 2026; with fewer than 30 quarters, it is $565 per month in 2026. Even when Part A has no premium, you still pay costs when you use it: the inpatient hospital deductible is $1,736 per benefit period in 2026, plus coinsurance, your share of costs, for longer stays. So Part A is often premium-free, but using it still has out-of-pocket costs.
What is the Medicare Part A deductible?
The Medicare Part A inpatient hospital deductible is $1,736 per benefit period in 2026.
A deductible is the amount you pay before Medicare starts covering its share. With Part A, this deductible applies per benefit period rather than per year. A benefit period starts the day you are admitted as an inpatient and ends after you have been out of the hospital or a skilled nursing facility for 60 days in a row. That means if you have separate hospital stays far apart in the same year, you could owe the deductible more than once. After the deductible, Part A covers your inpatient costs for a set number of days before daily coinsurance, your share of costs, begins.
Does Medicare Part A cover nursing home care?
Medicare Part A covers short-term skilled nursing facility care, but not long-term nursing home stays.
After a qualifying inpatient hospital stay, Part A can cover skilled nursing care, meaning care that requires trained medical staff, for a limited number of days. What Part A does not cover is long-term custodial care, which is help with daily activities like eating, bathing, or dressing when that is the only care you need. Many people are surprised by this, because a nursing home stay for custodial reasons is generally not a Medicare benefit. For that kind of long-term care, people often look to Medicaid, long-term care insurance, or personal savings. Part A covers the skilled, short-term side, not ongoing custodial living.
How long does Medicare Part A cover a hospital stay?
Medicare Part A covers a hospital stay in stages tied to the benefit period, not a single yearly limit.
After you pay the inpatient deductible of $1,736 per benefit period in 2026, Part A covers your covered hospital costs in full for the first 60 days of an inpatient stay. For days beyond that, you begin paying daily coinsurance, meaning a set share of the cost per day, with the amount increasing for longer stays. A benefit period starts when you are admitted and ends after 60 days out of the hospital or skilled nursing facility. There is also a lifetime reserve of extra days you can use once. The exact daily amounts vary, so the key idea is that longer stays bring added costs.
What does Medicare Part B cover?
Medicare Part B covers doctor visits, outpatient care, and many preventive services.
That includes care from physicians and specialists, lab tests, X-rays, mental health services, durable medical equipment such as walkers and wheelchairs, and preventive screenings and vaccines. Part B is the medical, outpatient side of Original Medicare, while Part A handles inpatient hospital care. Part B also covers some limited drugs given in a clinical setting, such as certain injections, though it does not cover most pharmacy prescriptions; those fall under Part D. In 2026, Part B has a standard monthly premium of $202.90 and a yearly deductible of $283, the amount you pay before Medicare shares costs. After the deductible, you typically pay coinsurance for covered services.
How much is Medicare Part B?
The standard Medicare Part B premium is $202.90 per month in 2026.
A premium is the amount you pay each month to keep the coverage. Most people pay this standard amount, but if your income is above a certain level, you may pay more through IRMAA, the Income-Related Monthly Adjustment Amount, which is an extra charge based on your reported income. IRMAA starts for single filers with income above $109,000 and joint filers above $218,000 in 2026. Part B also has a yearly deductible of $283 in 2026, which you pay before Medicare begins sharing costs. So the $202.90 is the baseline; higher earners pay more, and the deductible is separate from the monthly premium.
Is Medicare Part B mandatory?
Medicare Part B is not mandatory, but delaying it can cost you.
Part B covers doctor visits and outpatient care, and you can choose to turn it down or delay it. However, if you do not sign up when you are first eligible and you do not have other qualifying coverage, such as coverage from a current employer, you may owe a late enrollment penalty. That penalty is an amount added to your Part B premium, and it can last for as long as you have Part B. In 2026, the standard Part B premium is $202.90 per month. So while Part B is technically optional, skipping it without qualifying coverage can lead to a lasting higher cost.
Is the Part B deductible per year or per visit?
The Medicare Part B deductible is per year, not per visit.
A deductible is the amount you pay before Medicare starts sharing covered costs. For Part B, you pay this deductible once each calendar year, and in 2026 it is $283. After you meet it, you generally pay coinsurance, your share of the cost, for covered services for the rest of the year rather than starting the deductible over at each appointment. This is different from Part A, where the inpatient deductible applies per benefit period and can occur more than once a year. So with Part B, the $283 is a single yearly amount that resets at the start of each new calendar year.
