Medicare Part A Explained
Hospital Insurance Made Simple
Medicare Part A is often called hospital insurance. It helps cover certain inpatient care, including care you receive when you are formally admitted to a hospital, short-term skilled nursing facility care after a qualifying hospital stay, hospice care, and some home health care services.
Part A is one of the two parts of Original Medicare, along with Medicare Part B. Original Medicare includes Part A for hospital insurance and Part B for medical insurance.
Our goal is to help you understand what Medicare Part A does, what it may help cover, what it does not cover, and what costs you may be responsible for.
What Is Medicare Part A?
Medicare Part A is the part of Medicare that helps cover certain types of inpatient and facility-based care.
Most people think of Part A as the part of Medicare that helps with hospital stays. That is true, but Part A can also help cover some skilled nursing facility care, hospice care, and certain home health services when Medicare’s rules are met.
A simple way to remember it: Part A helps cover care connected to a hospital stay, skilled nursing care, hospice care, and certain home health services.
It does not cover every healthcare expense, and it does not work the same way as a full health insurance plan by itself.
What Does Medicare Part A Cover?
Medicare Part A may help cover several major categories of care.
Inpatient Hospital Care
Part A usually helps cover inpatient hospital care when you are formally admitted to the hospital with a doctor’s order and the hospital accepts Medicare. Medicare-covered inpatient hospital services may include a semi-private room, meals, general nursing, certain drugs, and other hospital services and supplies related to your inpatient treatment.
It is important to know that being in the hospital overnight does not always mean you are considered an inpatient. Your hospital status matters because it can affect what Medicare pays and what you may owe.
Skilled Nursing Facility Care
Medicare Part A may help cover short-term care in a skilled nursing facility if you meet Medicare’s requirements. This is not the same as long-term custodial care. Skilled nursing facility care generally means care that must be provided by, or under the supervision of, skilled nursing or therapy professionals.
In many cases, Part A skilled nursing facility coverage requires a qualifying inpatient hospital stay of at least three days, and you generally must enter the skilled nursing facility within a short time after leaving the hospital.
Hospice Care
Medicare Part A can help cover hospice care for people who meet Medicare’s hospice eligibility requirements. Hospice is end-of-life care for people with an illness that cannot be cured, and it focuses on comfort care rather than treatment intended to cure the terminal illness.
To qualify for hospice care under Medicare, certain requirements must be met, including certification by doctors that the person is terminally ill with a life expectancy of six months or less if the illness runs its normal course.
Some Home Health Care
Medicare may cover certain home health services under Part A and/or Part B if you are eligible. Covered home health services may include part-time or intermittent skilled nursing care, therapy services, medical social services, and certain home health aide services when specific conditions are met.
Medicare does not cover everything at home. For example, Medicare does not pay for 24-hour-a-day care at home, meal delivery, homemaker services unrelated to your care plan, or custodial personal care when that is the only care you need.
What Does Medicare Part A Not Cover?
Medicare Part A does not cover every cost related to hospital or facility care.
For inpatient hospital care, Medicare does not cover items such as private-duty nursing, a private room unless medically necessary, personal care items, or a television or phone in your room if there is a separate charge.
Part A also does not generally cover long-term custodial care, which means help with daily living activities such as bathing, dressing, or using the bathroom when that is the only care you need. Medicare’s home health coverage page also explains that custodial or personal care alone is not covered as home health care.
That is one of the biggest misunderstandings about Medicare: Medicare may help with skilled medical care, but it is not designed to pay for long-term personal care.
Is Medicare Part A Free?
Many people do not pay a monthly premium for Medicare Part A. This is often called premium-free Part A.
In 2026, most people pay $0 for Part A because they or a spouse paid Medicare taxes long enough while working, generally at least 10 years. People who do not qualify for premium-free Part A may be able to buy it and pay a monthly premium.
Even if you do not pay a monthly premium for Part A, that does not mean Part A is completely free. You may still have deductibles, coinsurance, and other costs depending on the care you receive.
Medicare Part A Costs
Part A has costs that are different from many other types of insurance.
In 2026, the Medicare Part A inpatient hospital deductible is $1,736 per benefit period before Original Medicare starts to pay. Medicare states that there is no limit to the number of benefit periods you can have in a year, which means you may pay the Part A deductible more than once in a year.
For inpatient hospital care in 2026, after you pay the Part A deductible:
Days 1–60: $0 per day
Days 61–90: $434 per day
Days 91–150: $868 per day while using lifetime reserve days
After day 150: You pay all costs
These amounts apply to each benefit period.
What Is a Benefit Period?
A benefit period is how Medicare measures your use of inpatient hospital and skilled nursing facility services.
This is different from a calendar year. A benefit period begins when you are admitted as an inpatient to a hospital or skilled nursing facility. It ends after you have gone 60 days in a row without receiving inpatient hospital care or skilled nursing facility care.
This matters because your Part A deductible is based on benefit periods, not simply once per year. Medicare explains that there is no limit to the number of benefit periods you can have in a year.
Part A and Skilled Nursing Facility Costs
For skilled nursing facility care in 2026, Medicare Part A costs depend on how long you are receiving covered skilled nursing facility care during a benefit period.
In 2026:
Days 1–20: $0 per day
Days 21–100: $217 per day
Days 101 and beyond: You pay all costs
Medicare limits skilled nursing facility coverage to 100 days in each benefit period.
Part A vs. Part B
Medicare Part A and Part B work together, but they cover different types of care.
Part A is hospital insurance. It generally focuses on inpatient hospital care, skilled nursing facility care, hospice care, and some home health care.
Part B is medical insurance. It generally helps cover doctor visits, outpatient services, preventive care, durable medical equipment, and other medically necessary services.
Original Medicare includes both Part A and Part B. After you sign up for Part A and Part B, you can choose how you want to receive your Medicare coverage, including Original Medicare or Medicare Advantage.
Why Part A Matters
Medicare Part A is one of the foundational pieces of Medicare.
It helps protect you from some of the major costs associated with inpatient hospital care and certain facility-based care. But Part A by itself is not the whole Medicare picture.
To fully understand your Medicare coverage, you also need to understand:
Medicare Part B
Prescription drug coverage
Medicare Supplement Insurance, also called Medigap
Medicare Advantage
Enrollment periods
Out-of-pocket costs
Learning Part A first gives you a stronger foundation for understanding the rest of Medicare.
Common Questions About Medicare Part A
Does Medicare Part A cover doctor visits?
Not usually. Doctor visits are generally covered under Medicare Part B, not Part A. Medicare Part A mainly helps cover certain inpatient and facility-based care, while Part B helps cover medical and outpatient services.
Does Medicare Part A cover emergency room visits?
Emergency room care is usually outpatient care unless you are formally admitted to the hospital as an inpatient. If you are admitted as an inpatient with a doctor’s order, Part A may help cover the inpatient hospital stay. Medicare explains that inpatient hospital care generally requires that you be admitted as an inpatient with a doctor’s order.
Does Medicare Part A cover nursing home care?
Medicare Part A may help cover short-term skilled nursing facility care if Medicare’s requirements are met. It does not generally cover long-term custodial care when that is the only care you need.
Do I need Medicare Part B if I have Part A?
Many people enroll in both Part A and Part B because Original Medicare includes both hospital insurance and medical insurance. Medicare explains that Original Medicare includes Part A and Part B, and people generally sign up for both before choosing how they want to receive their Medicare coverage.
Can I have Part A without paying a premium?
Many people qualify for premium-free Part A because they or a spouse paid Medicare taxes long enough while working, generally at least 10 years. People who do not qualify for premium-free Part A may be able to buy it.
The Simple Takeaway
Medicare Part A is hospital insurance.
It can help cover inpatient hospital care, short-term skilled nursing facility care, hospice care, and some home health care services. But it does not cover everything, and you may still have deductibles, coinsurance, or other out-of-pocket costs.
Understanding Part A is one of the first steps toward understanding Medicare as a whole.
