Medicare Part A is free for most people at 65, but "free" has conditions

If you or your spouse paid Medicare taxes while working, you will not pay a monthly premium for Medicare Part A (hospital insurance) when you turn 65. You have already paid for it through payroll deductions over your working years. However, Part A is not entirely free — you will pay deductibles and coinsurance when you actually use hospital services.

The distinction matters because many people assume "free Part A" means no costs at all. It means no monthly bill. The costs come when you are admitted to a hospital, skilled nursing facility, or hospice.

Key Takeaways

  • Most people pay zero monthly premium for Part A at 65 if they or a spouse worked and paid Medicare taxes for at least 10 years.
  • You will still pay a deductible (currently $1,676 per hospital stay) and coinsurance for days beyond the first 60 in the hospital.
  • If you do not have 10 years of Medicare tax history, you can buy Part A coverage, but the monthly premium can be $278 to $556 depending on your work history.
  • Part A covers inpatient hospital stays, skilled nursing care after hospitalization, hospice, and some home health services — but only under specific conditions.
  • You must be enrolled in Part A to use it; enrollment happens automatically at 65 if you are receiving Social Security, but you should verify your coverage.

Who gets Part A with no monthly premium

You may have access to for premium-free Part A if you are 65 or older and you (or your spouse, or ex-spouse if married 10+ years) worked and paid Medicare taxes for at least 10 years total. The work does not have to be consecutive, and it does not have to be recent — only that the total adds up to 10 years.

If you are already receiving Social Security retirement benefits when you turn 65, Medicare Part A enrollment happens automatically. You will receive a Medicare card in the mail about three months before your 65th birthday. If you are not yet taking Social Security, you will need to contact Social Security to enroll in Medicare.

Railroad workers and some federal employees may have different rules. If you worked for the railroad, contact the Railroad Retirement Board. If you were a federal employee, your agency's benefits office can tell you how your coverage works.

What Part A actually costs when you use it

The monthly premium is zero, but hospital bills are not. When you are admitted to a hospital as an inpatient, you pay a deductible — a flat amount per stay. As of 2024, that deductible is $1,676. This applies to each separate hospital stay, even if they happen in the same month.

After you pay the deductible, Medicare covers all costs for days 1 through 60 of your hospital stay. On days 61 through 90, you pay coinsurance — a daily amount that you are responsible for. As of 2024, that is $419 per day. If you stay longer than 90 days, you enter your lifetime reserve days, which are 60 additional days Medicare will cover during your lifetime, but you pay $838 per day for those.

For skilled nursing facility care (not regular nursing home care — this is care after a hospital stay), you pay nothing for days 1 through 20, then $209.50 per day for days 21 through 100. After day 100, you pay all costs yourself.

If you do not have 10 years of work history

If you did not work long enough to may have access to for premium-free Part A, you can still buy it. The monthly premium depends on how many years you or your spouse worked and paid Medicare taxes. If you have 30 to 39 quarters of coverage (roughly 7.5 to 10 years), the premium is $278 per month as of 2024. If you have fewer than 30 quarters, the premium is $556 per month.

These premiums change each year. You can contact Social Security or Medicare to find out what your specific premium would be based on your work history. Some people in this situation choose not to buy Part A and instead rely on Part B and Part D (prescription drug coverage) plus a Medigap or Medicare Advantage plan, though this is usually more expensive overall.

When Part A does not cover the bill

Part A covers inpatient hospital care, but only if you are admitted as an inpatient — not if you are in observation status. This distinction is important because observation stays look like hospital stays but are classified differently, and Part A may not cover them the same way. Always ask the hospital whether you are being admitted as an inpatient or placed in observation.

Part A does not cover custodial care in a nursing home — care that helps with daily living but is not medical care. It covers skilled nursing care only, and only after a hospital stay of at least three days. It does not cover assisted living facilities, independent living communities, or long-term care insurance.

Part A also does not cover services outside the United States, except in very limited circumstances (Canada or Mexico if you are closer to those countries than to a U.S. hospital). If you travel internationally, you will need separate travel insurance or out-of-pocket funds for any hospital care.

How to verify your Part A coverage

You can check whether you are enrolled in Part A by creating an account on Medicare.gov or by calling Medicare at 1-800-MEDICARE (1-800-633-4227). Have your Social Security number ready. The representative can tell you your enrollment status, your deductible amount for the current year, and any other coverage details.

If you are within three months of turning 65 and have not yet received your Medicare card, contact Social Security to make sure your enrollment is in process. If you turned 65 more than three months ago and have not received a card, call Medicare directly.

If you are still working at 65 and your employer offers health insurance, you may be able to delay Part A enrollment without penalty, but the rules are complex. Ask your employer's benefits office and Medicare before you decide to delay.

Frequently Asked Questions

Do I have to take Part A at 65 if I am still working?

If your employer has 20 or more employees and offers health insurance, you can delay Part A without penalty. However, most people should enroll anyway because Part A has no monthly premium and covers hospital costs. Talk to your employer's benefits office and Medicare before you decide to delay.

What is the difference between Part A and Part B?

Part A covers inpatient hospital stays, skilled nursing care, hospice, and some home health services. Part B covers outpatient services like doctor visits, lab tests, imaging, and preventive care. Most people need both, and Part B does have a monthly premium.

If Part A is free, why do I still owe money after a hospital stay?

Part A is free as a monthly premium, but you pay when you use it. You pay a deductible per hospital stay and coinsurance for longer stays. This is different from having no costs — it means you have already paid for the insurance through taxes, not that hospital care itself is free.

Can I get Part A if I am not a U.S. citizen?

You must be a U.S. citizen or a lawful permanent resident (green card holder) who has lived in the U.S. for at least five consecutive years. If you are not sure about your status, contact Medicare or Social Security to discuss your specific situation.

What happens if I do not enroll in Part A when I turn 65?

If you delay enrollment without a valid reason (like employer coverage), you may pay a penalty when you do enroll — a 10 percent increase in your premium for twice the number of years you were late. Since Part A is free for most people, there is usually no reason to delay.
