Medicare Part A: Coverage, Costs, and Enrollment

Medicare Part A is the part of Original Medicare that helps pay for inpatient hospital care, limited skilled nursing facility care, hospice, and certain qualifying home health services. If you are turning 65 or helping a parent prepare for Medicare, understanding Part A can make the rest of the coverage decision easier. This guide, written by Deborah Lader, explains what Medicare Part A covers, how eligibility and work history affect premiums, what 2026 cost sharing looks like, and when to enroll.

What is Medicare Part A?

Medicare Part A is also called Hospital Insurance. It is one part of Original Medicare, the federal health coverage program for people who qualify by age or disability. Part A focuses on facility-based and end-of-life care. Part B, by contrast, generally helps pay for doctor services, outpatient care, preventive services, and medical equipment.

In plain language, Medicare Part A is designed to help when you need care in a hospital, a Medicare-certified skilled nursing facility, or a hospice program. It can also help with certain home health services when you meet Medicare's eligibility rules. Part A does not pay every medical bill, and it does not replace the need to understand Part B, prescription coverage, or supplemental coverage.

For an official overview of Medicare costs and the current figures, review Medicare.gov's Medicare costs page. Medicare rules and cost amounts can change, so use the official source to confirm details for your situation.

What does Medicare Part A cover?

Medicare Part A generally covers medically necessary inpatient and facility-based services when you meet the applicable eligibility requirements and receive care from a Medicare-approved provider. The four main areas are inpatient hospital care, skilled nursing facility care, hospice, and qualifying home health care.

• Inpatient hospital care: Covered services can include a semi-private room, meals, general nursing, certain drugs, and other hospital services and supplies included in inpatient treatment.
• Skilled nursing facility care: Part A may cover short-term skilled nursing or therapy after a qualifying inpatient hospital stay and when other conditions are met.
• Hospice care: Part A hospice benefits can cover comfort-focused care for a person certified as terminally ill and choosing hospice care.
• Qualifying home health care: Medicare may cover part-time or intermittent skilled services at home when a person is homebound and meets the plan of care and provider requirements.

Coverage is not the same as automatic payment for every service. The facility, provider, admission status, medical necessity, benefit period, and other rules can affect whether Medicare pays. Always ask the hospital or provider how your care will be billed and whether the provider accepts Medicare.

How does Medicare Part A cover inpatient hospital care?

Medicare Part A generally covers inpatient hospital care when a doctor orders inpatient admission and the hospital accepts Medicare. Covered services may include a semi-private room, meals, general nursing, certain drugs, and supplies that are part of the inpatient treatment. Part A does not generally cover private-duty nursing, a private room unless medically necessary, personal care items, or separately billed television and telephone charges.

One important distinction is the difference between being formally admitted as an inpatient and being held for observation. Observation services may take place in a hospital but do not automatically count as an inpatient stay for every Medicare rule. Ask whether you are formally admitted and request an explanation if the status is unclear.

Medicare's inpatient hospital care guidance provides the current coverage details and facility rules. It is a useful source to review with a caregiver before a planned procedure or admission.

How much does Medicare Part A cost in 2026?

Most people do not pay a monthly premium for Medicare Part A because they or a spouse paid Medicare taxes while working for the required period. When cost sharing applies, the amount depends on the type and length of care. In 2026, the Part A inpatient hospital deductible is 1,736 dollars for each benefit period. The deductible is not an annual deductible, so it can apply again if a new benefit period begins.

These figures describe Original Medicare. A Medicare Advantage plan can use different deductibles, copayments, and out-of-pocket rules. If you choose Medicare Advantage, compare the plan's Evidence of Coverage and Summary of Benefits rather than assuming Original Medicare cost sharing applies.

What is a Medicare Part A benefit period?

A benefit period begins when you are admitted as an inpatient and ends after you have been out of inpatient hospital or skilled nursing facility care for 60 consecutive days. Because the Part A deductible applies by benefit period, a person can have more than one deductible in a year if separate benefit periods begin.

The lifetime reserve days are another important limit. Original Medicare provides 60 lifetime reserve days for inpatient hospital care beyond day 90. Once used, those reserve days are not restored. After day 150 of an inpatient hospital stay, Original Medicare does not pay the full cost of the stay. A Medigap policy or Medicare Advantage plan may change how your costs are handled, but you must check that coverage separately.

Does Part A cover skilled nursing facility care?

Medicare Part A can cover short-term skilled nursing facility care when all eligibility conditions are satisfied. In general, this includes a qualifying inpatient hospital stay of at least 3 consecutive days, admission to a Medicare-certified skilled nursing facility within the required timeframe, a medical need for daily skilled care or therapy, and Part A days remaining in the benefit period. Hospital observation time does not count as an inpatient day for the usual 3-day requirement.

Covered skilled nursing facility services can include a semi-private room, meals, skilled nursing, physical therapy, occupational therapy, speech-language therapy, medications, supplies, equipment, and related services. Coverage is limited to 100 days per benefit period under Original Medicare. In 2026, days 1-20 are 0 dollars per day after the Part A deductible, and days 21-100 are 217 dollars per day. After day 100, you pay all costs under Original Medicare.

Read the official Medicare skilled nursing facility coverage guidance for the complete eligibility list. Ask the hospital discharge planner whether your stay was inpatient or observation before assuming the 3-day requirement has been met.

Does Part A cover hospice care?

Medicare Part A hospice coverage is for comfort-focused care when a person has a terminal illness. To qualify, the person generally must have Medicare Part A, choose hospice care instead of curative treatment for the terminal illness, and have a hospice doctor and regular doctor certify a life expectancy of 6 months or less if the illness follows its normal course.

Hospice care can be provided at home, in a hospice facility, in a nursing facility, or in another setting approved for hospice services. The hospice team develops a plan of care and coordinates comfort and support services. Hospice benefits include two 90-day periods followed by unlimited 60-day periods, with recertification required for continued care.

In Original Medicare, there is generally no cost for covered hospice care from a Medicare-approved hospice. There may be a small copayment of up to 5 dollars for prescriptions related to pain and symptom management, and a 5% coinsurance for approved inpatient respite care. Room and board is not generally covered when you receive hospice at home or in a nursing facility. Review the official Medicare hospice care page for details.

Does Medicare Part A cover home health care?

Medicare can cover qualifying home health services when a person is homebound, needs part-time or intermittent skilled services, has a plan of care established and reviewed by a provider, and receives care from a Medicare-certified home health agency. Covered services can include skilled nursing, physical therapy, occupational therapy, speech-language therapy, medical social services, certain supplies and equipment, and home health aide services when they support skilled care.

Home health coverage is not the same as 24-hour in-home supervision or unlimited custodial care. Medicare does not generally cover homemaker services that are unrelated to the care plan, home-delivered meals, or personal care when that is the only care needed. Covered home health services usually have no cost, but durable medical equipment can involve 20% of the Medicare-approved amount after applicable Part B rules.

The way Medicare pays for home health services can depend on your eligibility, coverage, and the service being provided. Read Medicare's home health services guidance and ask the agency which services are covered before care begins.

Who qualifies for premium-free Medicare Part A?

Most people qualify for premium-free Medicare Part A based on their own or a spouse's Medicare-covered work history. The common benchmark is about 40 quarters, or 10 years, of work in which Medicare taxes were paid. The Social Security Administration keeps the official record of your work credits, so check with SSA if you are unsure whether you qualify.

If you do not qualify for premium-free Part A, you may be able to buy Part A. In 2026, the monthly premium is generally 311 or 565 dollars, depending on how many quarters of Medicare-covered work you or your spouse have. If you buy Part A, you also generally need to enroll in Part B. The premium and eligibility rules can be different for people who qualify for Medicare before age 65 because of disability or certain medical conditions.

Medicare Part A is only one part of the decision. People who want Medicare Advantage or an MAPD plan must be enrolled in both Part A and Part B. Grey State Financial can compare plans available in your area and explain how hospital coverage fits with doctors, prescriptions, networks, and other benefits.

When should I enroll in Medicare Part A?

For most people, the Initial Enrollment Period is a 7-month window. It begins 3 months before the month you turn 65, includes your birthday month, and ends 3 months after the birthday month. Enrolling early can help your coverage start on time. The exact effective date can depend on when you enroll.

If you are already receiving Social Security benefits at least 4 months before turning 65, Medicare says you may be enrolled automatically in Part A and Part B. If you are not receiving benefits, you generally need to apply through Social Security. Visit the official Medicare enrollment timing page or Social Security Medicare sign-up page to confirm the current process.

People who continue working past 65 should coordinate Medicare timing with their employer benefits administrator and Social Security. Employer size, the type of coverage, health savings account contributions, and whether you qualify for premium-free Part A can affect the best next step. Do not assume that delaying one part of Medicare means you should delay every part.

How does Part A fit with the rest of Medicare?

Original Medicare includes Part A and Part B. Part A helps with hospital and facility-based services, while Part B generally helps with physician and outpatient services. Most people who stay with Original Medicare also consider Part D prescription drug coverage and may consider a Medicare Supplement plan to help with certain out-of-pocket costs.

Another route is Medicare Advantage, also called Part C. Medicare Advantage plans are offered by private Medicare-approved insurers and generally combine Part A and Part B coverage in one plan. MAPD plans also include prescription drug coverage. Plans can have networks, copays, annual out-of-pocket limits, and extra benefits on select plans. See the Grey State Financial Medicare Advantage guide for an overview, and review plan-specific documents before enrolling.

Medicare Part A FAQs

Is Medicare Part A free for everyone?

No. Most people qualify for premium-free Part A through their own or a spouse's work history, but people who do not have enough Medicare-covered work credits may be able to buy Part A. In 2026, the premium is generally 311 or 565 dollars per month, depending on work history.

Does Medicare Part A pay 100% of hospital costs?

No. Under Original Medicare, you generally pay the Part A deductible for each benefit period. In 2026, hospital days 1-60 are 0 dollars per day after the deductible, days 61-90 are 434 dollars per day, and days 91-150 are 868 dollars per day while using lifetime reserve days. After day 150, you pay all costs.

Do I need both Part A and Part B?

Part A and Part B work together in Original Medicare, but whether you need or should enroll in both depends on your circumstances. You must have both Part A and Part B to qualify for a Medicare Advantage or MAPD plan. Ask Social Security and your employer benefits administrator about timing if you are still working.

Does Part A cover prescription drugs?

Part A may cover certain drugs supplied as part of an inpatient hospital, skilled nursing, or hospice service. It is not general outpatient prescription drug coverage. Most people who want outpatient prescription coverage consider a stand-alone Part D plan or a Medicare Advantage plan that includes drug coverage.

What is the difference between Part A and Part B?

Part A primarily covers inpatient hospital care, skilled nursing facility care, hospice, and qualifying home health services. Part B generally covers doctor services, outpatient care, preventive services, and durable medical equipment. Together, they form Original Medicare.
