Medicare Part A premium

Most people do not pay a premium for Medicare Part A (hospital insurance). But those who don’t receive premium-free Part A may pay up to $471 per month in 2021, depending on how many years they have worked and paid Medicare taxes.

The 2021 Part A premium is $259 per month if you paid Medicare taxes for 30-39 business quarters, which is 7.5 years to nearly 10 years, and $471 per month if you worked fewer than 30 quarters, which is fewer than 7.5 years.

Medicare Part A deductible

The 2021 Medicare Part A deductible is $1,484 per benefit period.

You must meet the Part A deductible in each benefit period before Medicare Part A begins to pay for your inpatient care costs. A benefit period begins on the first day you are admitted for inpatient care, and it ends when you have been discharged and haven’t received inpatient care for 60 consecutive days.

You could potentially have more than one Part A benefit period in a single calendar year.

Medicare Part A coinsurance

The Part A coinsurance is the amount of money you may have to pay out-of-pocket for extended inpatient stays at hospitals and other long-term care facilities, after you reach your Part A deductible for that benefit period.

The first 60 days of an inpatient stay are covered in full for each benefit period after you hit your Part A deductible. If your inpatient hospital stay lasts longer than 60 days, you may have to pay the following Part A coinsurance costs:

  • 2021 Part A coinsurance for days 61-90: $371 per day
  • 2021 Part A coinsurance for days 91 and beyond: $742 per day for each lifetime reserve day
  • After you use all of your 60 lifetime reserve days, you are responsible for all costs

Note: your Part A coinsurance costs and Part A deductible reset with each new benefit period. As mentioned above, you could potentially face more than one Part A benefit period in a calendar year.

Medicare Part B premium

The standard monthly premium for Medicare Part B (medical insurance) is $148.50 per month in 2021.

People with higher incomes could potentially pay more for their Part B premiums. This higher amount is called the Income-Related Monthly Adjusted Amount, or IRMAA.

The following chart outlines what you might pay for your Part B premium in 2021, based on your reported income taxes from 2019.

Medicare Part B deductible

The 2021 Part B deductible is $203 annually.

You must meet this deductible before your Medicare Part B coverage starts paying its share.

Medicare Part B coinsurance

After you meet your Part B deductible, you are typically responsible for paying a 20 percent coinsurance for the Medicare-approved amount for your covered services.

Part B coinsurance can be applied to covered services like doctor's office visits, outpatient therapy, durable medical equipment and other Part B-covered services.

Medicare Supplement Insurance plans (also called Medigap) can help cover some of the out-of-pocket Medicare costs detailed above, such as deductibles, coinsurance and copayments.

  • In 2021, the high-deductible Medigap Plan F and high-deductible Plan G options have a deductible of $2,370 per year. The high deductible Plan F is not available to new beneficiaries who became eligible for Medicare on or after January 1, 2020.
