What Does IRMAA Stand For?

Updated: Nov 29, 2021


Income-related Monthly Adjustment Amount


The standard Part B premium amount in 2022 is $170.10. Most people pay the standard Part B premium amount. If your modified adjusted gross income as reported on your IRS tax return from 2 years ago is above a certain amount, you'll pay the standard premium amount and an Income Related Monthly Adjustment Amount (IRMAA).

The income-related monthly adjustment amount (IRMAA) is an extra charge added to your premium. It is a sliding scale with a set of statutory percentage-based tables used to adjust Medicare Part B and Part D prescription drug coverage premiums. The higher the beneficiary's range of modified adjusted gross income (MAGI), the higher the IRMAA.
