Most people pay no Part A premium, because they or a spouse paid Medicare taxes long enough while working. In 2026 the standard Part B premium is $202.90 a month and the Part B deductible is $283 a year (see the CMS fact sheet for 2026). If your income is higher, you pay more for Part B. A Medigap, Medicare Advantage or Part D plan adds its own premium, which varies by plan.
Part A: most people pay no premium
Part A is hospital insurance: inpatient hospital care, skilled nursing facility care, hospice and some home health care. You usually pay no monthly premium for it if you or a spouse paid Medicare taxes while working for long enough, generally ten years. That's about ninety-nine percent of people with Medicare, by CMS's count. If you get Medicare before 65, you pay no Part A premium either.
You pay the Part A deductible each time a new benefit period starts, and there's no limit to the number of benefit periods in a year, so you can pay it more than once. A benefit period starts the day you are admitted as an inpatient and ends when you have had no inpatient hospital care, or skilled care in a nursing facility, for sixty days in a row.
If you don't qualify for Part A without a premium, you might be able to buy it, as long as you also sign up for Part B. If you don't buy it when you're first eligible, you might pay a penalty. Here's how late enrollment penalties work.
Part B: the premium, the deductible and your share
Part B covers services from doctors and other health care providers, outpatient care, home health care, durable medical equipment and some preventive services. Most people pay a monthly premium for it.
You pay the Part B premium every month, even in a month when you use no Part B services, and the amount can change each year. It is usually taken out of your Social Security benefit; if you don't get benefits, or the benefit is too low, Medicare sends you a bill.
The twenty percent applies when your doctor accepts the amount Medicare approves as full payment, which is called accepting assignment. Original Medicare has no yearly limit on what you pay out of pocket unless you add supplemental coverage, such as a Medigap policy, or join a Medicare Advantage Plan.
When income raises the premium
If the modified adjusted gross income on your tax return from two years ago is above a set amount, you pay an income-related monthly adjustment amount, called IRMAA, in addition to the standard Part B premium, and an extra amount with a Part D plan. These amounts affect roughly eight percent of people with Part B.
Social Security tells you if you have to pay it. If a life-changing event such as marriage, divorce, the death of a spouse, a loss of income or an employer settlement payment reduced your household income, you can ask Social Security to lower the amount.
The same brackets add an amount to a Part D plan's premium: from $14.50 to $91.00 a month in 2026, added to the plan's own premium (from the CMS 2026 fact sheet).
What a Medigap, Advantage or drug plan adds
A plan you add to Original Medicare, or join instead of it, brings its own premium and costs. You keep paying the Part B premium either way.
Medicare Supplement (Medigap)
Monthly premiums vary with the policy you buy, where you live and other factors, and can change each year. Medigap usually helps pay your share of Part A and Part B costs, such as deductibles and coinsurance, and some policies cover emergency care when you travel out of the country. Here's how companies set Medigap prices.
Medicare Advantage (Part C)
Premiums, deductibles, copayments and coinsurance vary by plan and can change each year. Every plan has a yearly limit on what you pay out of pocket; once you reach it, the plan pays for your covered health services for the rest of the year. Some plans help pay all or part of your Part B premium. You can see Medicare Advantage and Medigap side by side.
Part D drug coverage
Premiums vary by plan, and higher incomes pay the extra IRMAA amount too. In 2026 no Medicare drug plan may have a deductible above $615, and once your out-of-pocket spending on covered drugs reaches $2,100 you pay nothing more out of pocket for covered Part D drugs for the rest of the year (Medicare.gov's drug cost page). There's more on how Part D drug coverage works.

Help paying Medicare costs
- Medicare Savings Programs. If you have limited income and resources, your state may help pay your Medicare premiums, deductibles and coinsurance through a Medicare Savings Program.
- Extra Help. A Medicare program that lowers Part D premiums, deductibles, coinsurance and other drug costs. You get it automatically if you have full Medicaid, help from a Medicare Savings Program or Supplemental Security Income; otherwise you can apply. While you get Extra Help, you don't pay a Part D late enrollment penalty.
- Your State Health Insurance Assistance Program. Your local State Health Insurance Assistance Program can help you apply. You can apply for Extra Help and a Medicare Savings Program at the same time.
In 2026 the Extra Help income limit is $23,940 for one person and $32,460 for a married couple, and the resource limits are $18,090 and $36,100 (Medicare.gov's Extra Help page). Those limits may go up each year, so check them when you apply.
Questions people ask
Who does not pay Medicare premiums?
Most people pay no Part A premium, because they or a spouse paid Medicare taxes long enough while working, generally ten years; CMS puts that at about ninety-nine percent of people with Medicare in its 2026 fact sheet. If you get Medicare before 65, you pay no Part A premium either. Most people do pay a Part B premium, though a state Medicare Savings Program can help pay it for people with limited income and resources, and some Medicare Advantage plans help pay all or part of it.
What is IRMAA, and what income triggers it?
IRMAA is the income-related monthly adjustment amount: an extra amount added to the Part B premium, and to a Part D premium, when the modified adjusted gross income on your tax return from two years ago is above a set level. For 2026 the level is $109,000 on an individual return and $218,000 on a joint return, based on 2024 income (see the CMS 2026 fact sheet). Social Security tells you if you owe it, and you can ask it to lower the amount after a life-changing event such as marriage, divorce, the death of a spouse or a loss of income.
Does Medicare pay 100% of your medical bills?
No. With Original Medicare you pay the Part A deductible for each benefit period and, after the Part B deductible, usually twenty percent of the amount Medicare approves for Part B services, and there is no yearly limit on what you pay out of pocket. A Medigap policy helps pay those shares. A Medicare Advantage Plan has a yearly out-of-pocket limit, after which it pays for your covered health services for the rest of the year.
Can I get help paying Medicare costs?
Yes, if your income and resources are limited. Medicare Savings Programs, run by your state, help pay Medicare premiums, deductibles and coinsurance. Extra Help lowers Part D premiums, deductibles and other drug costs; you get it automatically with full Medicaid, a Medicare Savings Program or Supplemental Security Income, and otherwise you can apply. You can apply for both at the same time, and your State Health Insurance Assistance Program can help.
