Original Medicare includes Medicare Part A and Medicare Part B. Medicare Part A is your hospital insurance, covering things like an inpatient hospital stay, and Medicare Part B is your medical insurance, covering things like doctor visits. The monthly premium for Part A is $0 for most people, but it does come with out-of-pocket costs like deductibles and coinsurances.
Here’s what to know about Part A coverage and costs.
What does Medicare Part A cover?
Medicare Part A typically covers costs related to four inpatient services: inpatient hospital care, skilled nursing facility care, hospice care and home health services.
Inpatient hospital care

If you don't qualify for premium-free coverage, you may be eligible to buy Part A coverage. If you must pay for Part A, the premium is as much as $565 per month in 2026, depending on you and your spouse's work and Medicare tax history
Centers for Medicare & Medicaid Services. Costs. Accessed Aug 28, 2025.
Aside from Part A premiums, there are other costs based on your health care use. If you have a Medigap plan, these costs may be covered by that insurance. If you have a Medicare Advantage policy, it has to cover the same services but may come with different copays, coinsurance and deductibles.
The table below summarizes your share of Part A costs when using Original Medicare.

🤓Nerdy Tip
Other parts of Medicare — including Part C (Medicare Advantage plans), Part D (prescription drug coverage) and Medigap plans — are available through private health 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 costs and rules may apply.
Does it make sense to enroll in Medicare Part A and postpone the rest?
For those getting health care from a large employer, enrolling in Part A if you qualify for premium-free Part A and delaying the rest until retirement might seem like a smart idea — but there are caveats.
If you’re contributing to a health savings account and want to keep doing that, keep in mind that you can’t save money to an HSA once you’ve signed up for Medicare. If you start Part A at 65, you should stop HSA contributions before your 65th birthday month. If you sign up after 65, stop six months before you plan to enroll in Part A, because Part A coverage gets back-dated six months or to your 65th birthday month, whichever is closest.
No. Although Medicare Part A covers a share of your eligible medical costs, you’re still responsible for some out-of-pocket costs unless you have a supplemental plan (Medigap) that covers them.
You’ll have to cover deductibles, and potentially coinsurance, if you’re hospitalized or in approved skilled nursing care. That deductible for hospital care is $1,736 in 2026 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 or your skilled nursing facility stay exceeds 20 days, you'll have to start paying coinsurance. If you enter a new benefit period after the previous one ended, you will pay the deductible again.
If you’re already receiving Social Security or Railroad Retirement Board benefits before age 65, you’ll automatically be enrolled in Original Medicare — including both Medicare Part A and Part B coverage — the month you turn 65.
If you are waiting to start Social Security benefits, you can separately enroll in Part A, Part B or both. Regardless of your choice, you must apply for coverage on SSA.gov.
Here's when you can enroll:
Initial enrollment period (IEP): 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. If your birthday is on the first of a month, your IEP begins four months before your birthday month and ends two months after.
Special enrollment period (if you qualify): Certain situations or life events will allow you to sign up for Part B and Premium-Part A outside of normal enrollment periods. These events include things like ending health coverage from an employer or missing sign-up due to a natural disaster.
General enrollment period: 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. Coverage starts the month after you sign up, and you may pay penalties for late enrollment. 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 until January to sign up, and coverage would start in February.
Those who aren’t eligible for a special enrollment period and miss the initial enrollment period could face trouble. They may have to pay permanent penalties for the delay in coverage, and they’ll have to cover their medical costs out-of-pocket while they wait for the next sign-up period.
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'll have available the month you turn 65 and whether you’ll be eligible for a special enrollment period.
