Medicare IRMAA, Explained
This is one of the more confusing parts of Medicare, so let me walk you through it plainly: IRMAA (Income-Related Monthly Adjustment Amount) is a surcharge added to your Medicare Part B and Part D premiums if your income is above certain thresholds.

Social Security determines whether IRMAA applies to you using your Modified Adjusted Gross Income (MAGI) from your tax return, typically from two years prior. If your income is above the threshold for your filing status, you'll pay a higher amount for Part B and, if applicable, Part D — on top of your regular premium.
It Can Apply Regardless of Plan Type
IRMAA isn't tied to a specific type of coverage — it applies whether you have Original Medicare, a Medicare Supplement plan, or Medicare Advantage, since it's based on your Part B and Part D premiums specifically, not the plan you choose.
What to Do If You Think IRMAA Doesn't Reflect Your Current Situation
Because IRMAA is based on income from a prior year, it can sometimes be based on a financial picture that no longer reflects your circumstances — for example, after retirement, a divorce, or the loss of a spouse. In situations like these, you can request a reconsideration from the Social Security Administration using Form SSA-44, providing documentation of the life-changing event.
Because IRMAA income thresholds and surcharge amounts are adjusted periodically, I always check the current figures directly with you rather than rely on outdated numbers.
