2024 Irmaa Brackets For Medicare Part B And Deductible. The centers for medicare and medicaid services (cms) have yet to release the 2025 irmaa surcharge amounts for part b. The standard monthly premium for medicare part b enrollees will be $174.70 for 2024, an increase of $9.80 from $164.90 in 2023.

One of the direct consequences of irmaa is the increase in monthly premiums for medicare part b and part d coverage. You won’t pay the irmaa directly to your insurance company if you have medicare advantage or medicare part d.
