Medicare Part A is the hospital insurance component of Medicare — and for most people it is free. Yet despite being the most fundamental piece of Medicare coverage many new enrollees do not fully understand what it covers, what it does not cover, what cost-sharing they are responsible for, and how its benefit periods work. Understanding Part A before you need it — not when you are already hospitalized and receiving bills — is one of the most practical things a Medicare beneficiary can do. This guide breaks down exactly what Medicare Part A covers in plain language with the specific numbers that apply in 2026.
Quick Answer: Medicare Part A covers inpatient hospital care, skilled nursing facility care (after a qualifying hospital stay), hospice care, and some home health care. For 2026 the hospital deductible is $1,676 per benefit period. Most people get Part A free if they or their spouse worked 40+ quarters (10 years) paying Medicare taxes. Part A does NOT cover custodial nursing home care, most dental care, or outpatient services.

What Part A Covers — Overview
Medicare Part A covers four main categories of care:
- Inpatient hospital care — when you are formally admitted as an inpatient
- Skilled nursing facility (SNF) care — after a qualifying hospital stay
- Hospice care — for terminal illness
- Home health care — limited skilled care in your home
The common thread in all Part A coverage is that it covers skilled care in an institutional or home setting — not custodial or personal care that does not require medical skill.
Hospital Coverage in Detail
When you are formally admitted to a hospital as an inpatient Medicare Part A pays for your covered services.
What hospital coverage includes:
- Semi-private room and board
- General nursing care
- Hospital meals
- Medications administered during the stay
- Lab tests and X-rays performed as part of inpatient care
- Medical supplies and equipment used during the stay
- Operating and recovery room services
- Intensive care unit services
- Physical, occupational, and speech therapy
- Mental health inpatient care
Critical distinction — inpatient vs observation status: Part A only covers you when you are formally admitted as an inpatient. If the hospital places you under “observation status” — even if you sleep there for multiple nights — you are technically an outpatient and Part B (not Part A) covers your services. This distinction matters enormously for skilled nursing facility qualification (see below). Ask your doctor and hospital specifically whether you are admitted as an inpatient.
Psychiatric hospital stays: Part A covers up to 190 days of inpatient psychiatric hospital care over your lifetime — a separate benefit from general inpatient hospital coverage.
Skilled Nursing Facility Coverage — How It Actually Works
Medicare Part A covers skilled nursing facility (SNF) care — but with specific requirements that trip up many beneficiaries and their families.
Requirements for SNF coverage:
- You had a qualifying inpatient hospital stay of at least 3 consecutive days (as an inpatient — not observation status)
- You are admitted to a Medicare-certified skilled nursing facility
- You need skilled care — skilled nursing, physical therapy, occupational therapy, or speech therapy
- Your doctor certifies that skilled care is necessary
What SNF coverage provides for 2026:
| Days in SNF | Your Cost |
|---|---|
| Days 1-20 | $0 — fully covered |
| Days 21-100 | $209.50 per day coinsurance |
| Days 101+ | All costs — no Medicare coverage |
What “skilled care” means: The care must require the skills of licensed medical professionals — a registered nurse administering IV medications, a physical therapist providing rehabilitation, a speech therapist working on swallowing difficulties. Custodial care — help with bathing, dressing, eating — does not qualify as skilled care and is not covered by Medicare Part A regardless of where it is provided.
The 3-day qualifying stay rule: The observation status trap is most damaging here. A 4-day hospital stay under observation status does not qualify you for SNF coverage — even though you were physically in the hospital for 4 nights. You must have 3 consecutive days of formal inpatient admission to trigger SNF eligibility.
Hospice Care Coverage
Medicare Part A covers hospice care for beneficiaries who are terminally ill — certified by a doctor to have a life expectancy of 6 months or less if the illness runs its normal course.
What hospice coverage includes:
- Doctor and nursing services
- Medical equipment (hospital bed, wheelchair, oxygen)
- Medications for symptom control and pain relief
- Aide and homemaker services
- Physical, occupational, and speech therapy
- Social work services
- Spiritual and grief counseling for the patient and family
- Short-term inpatient care for pain and symptom management
- Short-term respite care (inpatient, to give family caregivers a break)
Your costs in hospice: Hospice is nearly free under Medicare. You pay $0 for hospice care itself and small copayments for drugs ($5 or less per prescription for symptom management) and respite care (5% of the Medicare-approved amount).
Electing hospice means giving up curative treatment: To receive Medicare hospice benefits you agree to focus on comfort care rather than curative treatment for your terminal illness. You can still receive Medicare coverage for other unrelated health conditions.
Home Health Care Coverage
Medicare Part A (and Part B) covers limited skilled home health care when you are homebound and need skilled medical care at home.
Requirements for home health coverage:
- You are homebound — leaving home requires considerable effort or is medically contraindicated
- You need skilled nursing care or therapy (physical, occupational, or speech) on an intermittent basis
- A doctor certifies the home health plan
- Services are provided by a Medicare-certified home health agency
What home health coverage includes:
- Part-time skilled nursing care
- Physical, occupational, and speech therapy
- Part-time home health aide services (only when skilled care is also needed)
- Medical social services
- Durable medical equipment (at 80% coverage with 20% coinsurance)
What home health does NOT cover: Round-the-clock nursing care, personal care services not connected to skilled care, homemaker services (cooking, cleaning), and custodial care that does not require medical skill.
What Part A Does NOT Cover
Understanding Part A’s exclusions prevents the financial surprises that most commonly affect Medicare beneficiaries.
- Custodial nursing home care: Long-term care in a nursing home for help with daily living activities — the most common and expensive misconception. Medicare does not cover this
- Most dental care: Routine dental exams, cleanings, fillings, dentures — not covered by Part A
- Routine vision care: Eye exams for glasses, eyeglasses, contact lenses — not covered
- Routine hearing care and hearing aids: Not covered by Part A
- Outpatient care: Doctor visits, outpatient surgery, lab tests outside a hospital admission — covered by Part B, not Part A
- Private room upgrades: Part A covers semi-private rooms — private rooms are at your expense unless medically necessary
- Personal convenience items: TV, phone in hospital room, personal care items
Your Costs — Deductibles and Coinsurance 2026
Part A is not free to use even though most people pay no premium. Cost-sharing applies to all Part A services.
Hospital inpatient costs 2026:
| Hospital Days | Your Cost |
|---|---|
| Days 1-60 | $1,676 deductible per benefit period |
| Days 61-90 | $419 per day coinsurance |
| Days 91-150 | $838 per day (lifetime reserve days) |
| Days 151+ | All costs — no coverage |
No out-of-pocket maximum: Original Medicare Part A has no out-of-pocket maximum — costs can accumulate without limit for extended hospital stays. This is why Medigap supplement coverage is valuable — Plan A through Plan G cover various portions of this cost-sharing.
Understanding the Benefit Period
The benefit period concept is unique to Medicare and confuses many beneficiaries — particularly because the Part A deductible applies per benefit period, not per year.
How benefit periods work:
- A benefit period begins the day you are admitted as an inpatient in a hospital or skilled nursing facility
- A benefit period ends when you have been out of a hospital or SNF for 60 consecutive days
- If you are readmitted after 60 days a new benefit period begins — and the $1,676 deductible applies again
- There is no limit on the number of benefit periods you can have in a year
Example: You are hospitalized in January (benefit period 1 — $1,676 deductible). You are discharged and remain at home for 65 days. You are readmitted in April (benefit period 2 — another $1,676 deductible). Both deductibles apply in the same calendar year because each hospitalization started a new benefit period.
Frequently Asked Questions
Does Medicare Part A cover nursing home care?
Medicare Part A covers skilled nursing facility care short-term after a qualifying hospital stay — for up to 100 days with significant cost-sharing after day 20. It does NOT cover long-term custodial nursing home care — the kind of 24-hour care many people need for Alzheimer’s, dementia, or other conditions requiring ongoing personal assistance. Long-term custodial care is covered by Medicaid (for those who qualify financially) or by private long-term care insurance. This is one of the most common and financially devastating Medicare misconceptions.
What is the Part A premium and who pays it?
Most people pay $0 premium for Part A because they or their spouse worked at least 40 quarters (10 years) while paying Medicare payroll taxes. People with 30-39 quarters of work pay $285/month in 2026. People with fewer than 30 quarters pay $518/month. If you are unsure whether you qualify for premium-free Part A check your Social Security earnings record at SSA.gov — it shows your Medicare-covered quarters of work.
Can I use Part A at any hospital?
With Original Medicare you can use Part A at any hospital that accepts Medicare — approximately 93% of all hospitals in the United States. You do not need referrals or prior authorization for most hospital admissions under Original Medicare. If you have a Medicare Advantage plan (Part C) rather than Original Medicare you are typically limited to the plan’s hospital network for non-emergency care.
Conclusion
Medicare Part A is the foundation of Medicare hospital coverage — free for most beneficiaries, broadly accepted at nearly all US hospitals, and covering the major inpatient care categories most people will eventually need. Understanding its coverage before a medical crisis — the benefit period structure, the observation status trap, the SNF qualification requirements, and most importantly what it does NOT cover — prevents the financial surprises that catch many beneficiaries off guard. The most critical understanding: Part A covers skilled care, not custodial care. Long-term nursing home care for daily living assistance is not a Medicare benefit regardless of what you may have heard. Planning for that gap — through Medicaid planning, long-term care insurance, or family arrangements — is one of the most important financial preparations a Medicare beneficiary can make.
