Medicare Part A: What It Covers, What It Costs
Medicare Part A is the hospital insurance portion of Medicare. For most people, it’s premium-free.

Medicare Part A is the portion of Medicare that covers hospital care and related services. Unlike the other parts, it’s usually available without a premium. Here’s what to know.

Original Medicare — the government-run part of Medicare that you can enroll in through Social Security — is made up of two parts: Medicare Part A and Medicare Part B.
While Part B generally covers doctor's appointments and preventive care, Medicare Part A is hospital insurance and generally covers:
Inpatient hospital care
This covers hospital services you get when you’re admitted to a hospital on doctor’s orders, including semiprivate rooms, meals, general nursing and drugs for inpatient treatments. The hospital must accept Medicare.
Medicare Part A covers inpatient hospital care in a variety of facilities, including:
Acute care hospitals.
Critical access hospitals.
Inpatient rehabilitation facilities.
Inpatient psychiatric facilities.
Long-term care hospitals.
Inpatient care as part of a qualifying clinical research study.
Skilled nursing facility care
You can get short-term care at a certified skilled nursing facility following a qualifying inpatient hospital stay of at least three days. Covered services include a semiprivate room, meals, skilled nursing care and other services, such as physical therapy and occupational therapy.
Other covered services include:
Speech-language pathology services.
Medical social services.
Medications.
Medical supplies and equipment used in the facility.
Ambulance transportation to the closest supplier of needed services that aren't available at your facility (if other transport would endanger your health).
Dietary counseling.
Swing bed services.
Hospice benefits
Hospice is the end-of-life care you receive if you're terminally ill, for example. Covered services include care from doctors, nurses and aides; medical equipment (such as wheelchairs); certain prescription drugs; occupational therapy; physical therapy; and grief and loss counseling for you and your family.
Covered services include part-time skilled nursing and home health aide care, occupational therapy, physical therapy, speech-language pathology services, medical social services and injectable osteoporosis drugs for women. Medicare does not pay for 24-hour-a-day care at home, meal delivery, homemaker services (if that's the only care you need), or personal care, such as bathing or dressing (if that's the only care you need).
$0 coinsurance per day for days 1-60 of each benefit period.
$371 coinsurance per day for days 61-90 of each benefit period.
$742 coinsurance per day for days 91 and beyond of each benefit period, up to your total lifetime reserve days (60 days over your lifetime).
All costs after exceeding lifetime reserve days.
Skilled nursing facility care
$0 coinsurance for days 1-20 for each benefit period (which starts on the day you’re admitted and ends when you haven’t received inpatient hospital care or care in a skilled nursing facility for 60 days).
$185.50 coinsurance per day of each benefit period for days 20-100.
All costs for days 101 and beyond.
Hospice
$0 for hospice care.
$5 or less on copayments for prescription drugs for pain relief or symptom relief at home.
5% of Medicare-approved amount for inpatient care, in some cases.
Home health services
$0 for covered home health services.
20% of the Medicare-approved amount for certain medical equipment, such as wheelchairs and walkers.
Nerdy tip: Other parts of Medicare — including Part C (Medicare Advantage plans), Part D (prescription drug coverage) and Medigap plans — are available through private insurers approved by Medicare. If you sign up for a Medicare Advantage plan, an alternative to Original Medicare, it will include at least the same coverage provided in Original Medicare. However, you may be limited to a certain network and different rules may apply.
Medicare Part A eligibility
Generally, you're eligible for Medicare Part A if you meet one of the following requirements, according to Medicare:
You are age 65 or older.
You've gotten disability benefits from Social Security or the Railroad Retirement Board for at least 25 months.
You receive disability benefits because you have Amyotrophic Lateral Sclerosis, also called ALS or Lou Gehrig’s disease.
You have End-Stage Renal Disease (ESRD) and meet certain requirements.
How much Medicare Part A costs
You may qualify for premium-free Medicare Part A if you or your spouse has worked and paid Medicare taxes for over 10 years, among other ways. To determine your eligibility, use Medicare's eligibility calculator.
If you don't qualify for premium-free coverage, you may be eligible to purchase Part A coverage. If you must pay for Part A, the monthly premium is either $259 or $471 in 2021, depending on you and your spouse's work and Medicare tax history.
“If you’re over 65 and you can afford it, it makes sense to pay for Part A,” says Jo Schneier, CEO and co-founder of Trusty.care, a Medicare quoting and enrollment tool for brokers, acknowledging that the premiums aren't cheap. “Original Medicare plus a supplement is probably going to be the best insurance you have,” he notes, referring to Medigap plans.

Frequently asked questions
For those getting health care from a large employer, enrolling in Part A and delaying the rest until retirement might seem like a no-brainer — but there are caveats.
“We used to tell people, go ahead and get into Medicare A, there’s no fee,” says Katy Votava, president of Goodcare, a consulting firm for the management of Medicare costs and planning, and author of the book “Making the Most of Medicare: A Guide for Baby Boomers.” “But you don’t want to enroll in Medicare [Part] A if you have an employer plan that lets you put money into health savings accounts.”
That’s because you won’t be able to make tax-free contributions to your HSA while enrolled in Medicare, she notes.
These types of plans — high-deductible health plans with HSAs — have become more common in recent years, Votava notes. Even if you don’t have one now, your company might change its coverage options and you might end up in one before retirement, she adds. If you’re unsure of how your coverage might change, it may be best to wait until your special enrollment period and sign up for parts A and B at the same time.
Here's what's not covered in Part A:
Deductibles and coinsurance
You’ll have to cover deductibles (and, potentially, coinsurance) if you’re hospitalized, for instance. In 2021, that deductible for hospital care is $1,484 per benefit period, which starts on the day you’re admitted and ends when you haven’t received inpatient hospital care or care in a skilled nursing facility for 60 days. If your hospital stay exceeds 60 days, you'll have to start paying coinsurance.
Outpatient hospital service
These are covered by Part B and include same-day surgeries or emergency services and X-rays ordered by your doctor, for instance.
Long-term care
While Part A covers a limited amount of time spent at skilled nursing facilities, it doesn’t cover long-term care in nursing homes.
Custodial care
Custodial care, or help with eating, getting dressed or bathing, isn't covered by Part A.
If you’re already receiving Social Security or Railroad Retirement Board benefits, you’ll automatically start receiving Original Medicare — including Medicare Part A coverage — the month you turn 65, in most cases.
This is the seven-month period starting three months before the month you turn 65, including your birthday month and ending three months after your birthday month.
This is the eight-month period starting at the month after your employment ends or the month after losing your qualifying employer insurance, whichever happens first. You can generally qualify for this special enrollment period if you or your spouse are receiving health care from a large employer when you turn 65.
This runs from Jan. 1 through March 31 every year. If you didn’t sign up when you were first eligible and weren’t eligible for a special enrollment period, you’ll have to wait for the general enrollment period to sign up. However, you may have to pay penalties for late enrollment, and your coverage would start only on July 1. So, for example, if you were to realize on April 1 that you needed to sign up for Medicare during the general enrollment period, you'd have to wait over a year to actually get that coverage — even if you signed up as soon as possible during the general enrollment period the following January.
Those who aren’t eligible for a special enrollment period and miss the initial enrollment period are really in trouble, says Votava of Goodcare.
“They’ll not only pay penalties for the rest of their life, [but they'll] have to wait long periods of time — it could be months, a year, or more than a year — before [they're] eligible to start coverage,” Votava says. And in the meantime, she notes, they’ll be covering 100% of their medical costs out-of-pocket.
While there aren’t penalties for Part A if you’re getting it premium-free, there are penalties for enrolling late in Parts B and D, which grow larger the longer you postpone your enrollment. Before turning 65, make sure you understand the type of coverage you have and whether you’re eligible for a special enrollment period.
The answer depends on the size of your employer.
Enrolling in premium-free Part A and postponing the other parts of Medicare has long been a strategy used by folks to get more coverage at no upfront cost. But it may not work in all cases.
It might seem redundant since you already have coverage, but you should enroll in Medicare parts A, B and D — or a Medicare Advantage plan that covers these — when you're first eligible to avoid costly penalties. Once enrolled, Medicare will generally be your primary coverage, meaning it will pay first, and your employer coverage will be secondary.
You can generally postpone enrollment in Medicare in this case with no penalties. After your coverage ends, you’ll get a special enrollment period, at which time you can enroll in Medicare and choose plans without late penalties. (If you were to enroll and keep your employer coverage, your Medicare would be secondary and your employer coverage would be primary.)
Before making your decision, confirm the details of your health coverage with your benefits manager.
