What Is the Cost of Medicare Part B in 2023?
Your Part B costs will typically come in the forms of premiums, deductibles, copayments, and coinsurance.
Premiums
Medicare Part B comes with a monthly premium. Most people pay the standard Part B premium, which is $174.70 per month in 2024.
If you are in a higher income bracket, though, you may pay have to pay more. You only have to pay a higher 2023 Part B premium if your yearly income is over $103,000 individually or $206,000 as a couple filing taxes jointly.
This increased amount is called the Medicare Income-Related Monthly Adjustment Amount (IRMAA).
Deductibles, Copayments and Coinsurance
Medicare Part B comes with a $240 annual deductible in 2024. Part B won’t pay for anything until you pay that amount each year that you use the coverage.
After you pay the deductible, you still pay for a portion of the services covered by Part B. This is usually 20% of the Medicare-approved amount for the service. Part B covers the other 80%.
If you don’t want to pay for deductibles or coinsurance, some Medicare Supplement insurance (also called Medigap) plans can help cover these and other out-of-pocket Medicare costs.
How Do I Get Medicare Supplement Part B?
Medicare Part B is optional. If you are automatically enrolled in Medicare Part A (hospital insurance), you will be automatically enrolled in Part B, but you may choose to opt out of it.
When you receive your red, white and blue Medicare card in the mail, you can follow the opt-out instructions that come attached and send the card back. If you don’t follow these instructions, you will get Part B and must pay the monthly premiums.
If you automatically enrolled in Part A and Part B, you will have to manually enroll in Medicare at your local social security office or through social security’s online portal.

Your Medicare IEP lasts for 7 months.
The best time to enroll in Part B is during your Medicare Initial Enrollment Period (IEP). This period begins three months before you turn 65 years old, includes the month of your birthday and continues on for three additional months.
