Does IRMAA Apply to Medicare Advantage Plans?

Yes, IRMAA applies to Medicare Advantage. It attaches to your Part B and Part D coverage, not to the flavor of Medicare you picked. Here is how the surcharges show up on an Advantage bill, the Part D wrinkle, and what a couple actually pays.

That is the short answer to whether IRMAA applies to Medicare Advantage plans, and it is the answer that surprises people who switched to Advantage specifically to save money. Everyone in a Medicare Advantage plan still pays the Part B premium every month, so the Part B surcharge follows you. And if your Advantage plan includes drug coverage, the Part D surcharge comes along too.

Why Medicare Advantage does not shield you from IRMAA

A Medicare Advantage plan changes how your care is delivered. It does not change your obligation to pay Part B. Social Security deducts the Part B premium, plus any IRMAA, from your benefit check or bills you directly, whether your card says Original Medicare or a private plan. In 2026 the standard Part B premium is $202.90, and with IRMAA the total monthly premium ranges from $284.10 to $689.90 depending on income.

About 8 percent of Medicare beneficiaries pay IRMAA in a given year. If your MAGI from two years ago crossed $109,000 single or $218,000 joint, you are in the club whether you chose Advantage or not.

The Part D wrinkle

Part D IRMAA only applies if you actually have Part D coverage. Most Advantage plans bundle it into an MAPD plan, and in that case the Part D surcharge, $14.50 to $91 a month in 2026, is added to your plan premium. But if your Advantage plan has no drug coverage and you carry no Part D plan at all, there is no Part D IRMAA to pay. The Part B surcharge still applies either way.

Two edge cases people ask about constantly: a $0-premium MAPD plan still gets both surcharges, because IRMAA is billed by Social Security, not by your plan. And a plan that rebates part of your Part B premium does not rebate the IRMAA portion.

What a couple actually pays

IRMAA is per person, so a married couple at the top tier pays the surcharge twice. That is how the combined annual number climbs past $13,000 in extra premiums on top of regular plan costs. It is one reason high-income retirees feel this cost more than almost any other Medicare expense: it is invisible when you pick the plan and unavoidable once the determination letter arrives.

If your income dropped since the lookback year because of a qualifying life-changing event, the surcharge is not necessarily final. Form SSA-44 lets you ask Social Security to use your current income instead.

Frequently Asked Questions

Does IRMAA apply to Medicare Advantage plans?

Yes. IRMAA is a surcharge on Medicare Part B and Part D, and Medicare Advantage enrollees still owe the Part B premium every month. The Part B surcharge applies regardless of which type of Medicare you have.

Do I pay Part D IRMAA if my Advantage plan has no drug coverage?

No. Part D IRMAA only applies when you have Part D coverage, whether through a standalone plan or an MAPD plan. Without any Part D coverage there is no Part D surcharge, though the Part B surcharge still applies.

Does IRMAA apply to a $0 premium Medicare Advantage plan?

Yes. IRMAA is billed by Social Security, not by your plan, so a $0 plan premium does not reduce it. You still owe the full Part B surcharge and, if your plan includes drug coverage, the Part D surcharge.

Who bills me for IRMAA on a Medicare Advantage plan?

The Social Security Administration, not your Advantage plan. The surcharge is usually deducted from your Social Security benefit check. If you are not receiving benefits, CMS bills you directly.

Can I appeal IRMAA if I am on a Medicare Advantage plan?

Yes, through the same process as everyone else. If a qualifying life-changing event reduced your income, file Form SSA-44 and ask Social Security to use your current income instead of the two-year-old tax return.
