Medicare IRMAA is an addition to your monthly Medicare Part B or Part D premium, that Medicare beneficiaries pay based on their income. How much additional cost you will have to pay is determined each year by the Centers for Medicare & Medicaid Services.

What Is IRMAA?

IRMAA is an acronym for income-related monthly adjustment amount. Depending on your income, you may be charged for IRMAA Part B and/or IRMAA Part D. This applies to Medicare beneficiaries with a higher income. IRMAA only applies to you if you are receiving Medicare Part B or Medicare Part D benefits.

When Was It Enacted?

The income-related monthly adjustment amount went into effect in 2003. It is a provision of the Medicare Modernization Act.

It now also includes beneficiaries of Medicare Part D.

How To Calculate IRMAA
