Medicare Part B Premium

What you pay for your Medicare Part B premium changes slightly each year and is based on income and when you enroll. For 2021, the standard Part B premium is $148.50.[1]

Part B Deductible and Coinsurance

Another cost of Part B is the Part B deductible and the related 20% coinsurance.

For 2021, the Part B deductible is $203. In 2020 it was $198. After you meet your deductible for the year, you typically pay 20% of the Medicare-approved amount for most doctor services (including most doctor services while you’re a hospital inpatient), outpatient therapy, and durable medical equipment (DME).


While most people pay the standard amount for their Medicare Premiums, you may pay less with assistance programs or more based on Modified Adjusted Gross Income (MAGI). If your income is high enough, you’ll pay the standard premium amount plus an additional amount called the Income Related Monthly Adjustment Amount (IRMAA).

The IRMAA Part B costs chart below from Medicare.Gov shows the standard premium and IRMAA adjusted premiums for 2021 based on income.
