What Does Medicare Part B Cost?

Medicare Part B covers medical services like doctor visits, outpatient care, and preventive services — but unlike Part A, it comes with an ongoing monthly premium. Here's how that cost is structured.

The Standard Premium

Medicare sets a standard Part B premium each year, and it typically changes annually. Because the amount is updated yearly, it's best to check the current figure directly on Medicare.gov or ask a licensed agent for the up-to-date number rather than relying on a figure that may be out of date.

Income-Based Adjustments (IRMAA)

If your income is above a certain threshold, you may pay more than the standard premium through an Income-Related Monthly Adjustment Amount (IRMAA), based on your tax return from two years prior.

The Annual Deductible

In addition to the monthly premium, Part B has an annual deductible that also typically changes each year. After you meet it, you generally pay 20% coinsurance for most Part B-covered services, unless you have supplemental coverage that helps with that cost.
