How much does Medicare Part A cost?
Medicare Part A is free for most people. You do not have to pay a premium for Part A if you or your spouse worked and paid Medicare taxes for at least 10 years. Part A does charge a deductible and copays. Part A deductibles are charged per benefit period. A benefit period begins the day you are admitted to the hospital and ends when you’ve been out of the hospital 60 days in a row.
You pay one deductible even if you have more than one hospital stay during a single benefit period. Below you'll see the different Medicare Part A costs that may apply. Costs are shown for 2024.

Each lifetime reserve day may be used only once, but you may apply the days to different benefit periods. Lifetime reserve days may not be used to extend coverage in a skilled nursing facility.
Medicare Part B
Medicare Part B (medical insurance) is the other half of Original Medicare. Part B covers care you receive in a clinic or hospital as an outpatient including most doctor services you receive as an inpatient, doctor visits, most routine and emergency medical services and some preventive care. The list below shows examples of some of the items and services Part B covers.

Note: Generally, Medicare Part B is not required. You can choose to opt out and only enroll in Part A, but you may need to enroll in both Part A and Part B to qualify for other coverage, such as a Medicare Advantage plan.
How much does Medicare Part B cost?
Medicare Part B shares some costs with you when you see the doctor or use other medical services. Part B has a monthly premium that is either deducted from your monthly Social Security benefits check or that you pay directly to Medicare. The amount you pay can vary depending on your tax reported income from two years prior.
Below you'll see the different costs that may apply. Costs shown are for 2024.
Part B premium
Per month:$174.70 to $594 in 2024, depending on income
Part B deductible
Per year:$240 in 2024
Part B coinsurance
Most medical services:20% of theMedicare-approved amount
Durable medical equipment:20% of theMedicare-approved amount
Outpatient mental health care:20% of theMedicare-approved amount
How Medicare Part B Cost Sharing Works
You will pay the Medicare Part B premium and share part of costs with Medicare for covered Part B health care services. Medicare Part B pays 80% of the cost for most outpatient care and services, and you pay 20%.
For 2024, the standard monthly Part B premium is $174.70.You'll pay the standard amount if:
- You enroll for the first time in 2024.
- You aren't receiving Social Security benefits.
- Your premiums are billed directly to you.
- You have Medicare and Medicaid, and Medicaid pays your premiums.
Your Part B premium may be less than the standard amount if you enrolled in Part B in 2022 or earlier and your premium payments are deducted from your Social Security check.
Your premium may be more than the standard amount based on your income. You will pay an income‑related monthly adjustment amount (IRMAA) if your reported income was above $103,000 for individuals or $206,000 for couples in 2024. Visit Medicare.gov to learn more about IRMAA.
And while Medicare will share your Part B health care costs with you, there is something called "Medicare assignment"that's important to understand.
Doctors and providers who accept Medicare assignment agree to take what Medicare pays—the Medicare-approved amount—as payment in full. Medicare reduces the approved amount it pays for doctors who don't accept Medicare assignment. Doctors who don't accept Medicare assignment may charge more than the Medicare-approved amount. You may have to pay the additional cost, which is called "excess charges."
Medicare Part B covers doctor visits, lab tests, preventive screenings and other outpatient health care services. Part B costs include a monthly premium, an annual deductible and coinsurance for most services.
How to enroll in Medicare Part A or Part B
If you are receiving Social Security or Railroad Retirement Board benefits, you will be enrolled in Medicare automatically when you turn 65 and get your Medicare card in the mail. If you are not enrolled automatically, you will need to sign up by yourself. You can enroll in Medicare Part A and Part B online at www.ssa.gov, in person at your local Social Security office or by phone at 1-800-772-1213 (TTY 1-800-325-0778).
Late Enrollment Penalties for Medicare Part A and Part B
Both Medicare Part A and Part B can have late enrollment premium penalties.
The Part A Late Enrollment Penalty
If you must pay a Part A premium and enroll late, you could pay a penalty. The Part A late enrollment penalty is 10% of the Part A premium. You pay the penalty in addition to your Part A premium for twice the number of years you delay enrollment.
Example: If you delay 2 years, you will pay an additional 10% of the Part A premium for 4 years (2 x 2 years).
The Part B Late Enrollment Penalty
The Part B penalty is 10% of the monthly premium amount for each full 12-month period enrollment is delayed. You pay the Part B premium penalty in addition to your Part B premium for as long as you have Medicare Part B.
Example: You delayed Part B 3 years. To calculate how much your penalty will cost, you'll multiply (10% of Part B premium) x (# of years enrollment is delayed). In this case, (10%) x (3). Thus, your Part B premium penalty will be 30% of the Part B premium.
What Original MedicareDoesn't Cover
Original Medicare doesn't cover everything. With a few exceptions, Original Medicare doesn't include coverage for prescription drugs. It also does not cover health care benefits you may have been used to getting with an employer plan such as dental, vision, hearing health care or wellness items like fitness memberships.
