Can I be assessed an Income-Related Monthly Adjustment Amount (IRMAA) for Medicare Part D if I am enrolled in a Medicare Advantage (MAPD) plan?

Yes.  If you are a Medicare beneficiary and your annual income (MAGI) exceeds certain limits - and you are enrolled in a Medicare Advantage plan (HMO, PPO, or PFFS) that includes prescription drug coverage (MAPD), then your MAPD actually includes Medicare Part D drug coverage (along with Medicare Part A and Medicare Part B coverage) - and you can be charged an Income-Related Monthly Adjustment Amount (IRMAA) for both your Medicare Part D and Medicare Part B coverage.

In short, Medicare Part D IRMAA is assessed to anyone getting Part D coverage from a stand-alone Medicare Part D plan (PDP) -- Medicare Advantage plan that includes drug coverage (MAPD) -- or a Medicare Cost plan - even if this coverage is paid for by your employer, union, or retiree health plan.

Question:  Will I pay Part D IRMAA if my Medicare Advantage plan does not have drug coverage?

No.  If you are enrolled in a Medicare Advantage plan that does not include prescription drug coverage (MA) and you do not have any other Medicare Part D prescription drug coverage, then you will not be charged Medicare Part D IRMAA -- but you will still pay Medicare Part B IRMAA.

Question:  What if I am enrolled in an MAPD with a $0 premium?

Even if you are enrolled in a Medicare Advantage plan (MAPD) with a $0 premium - or a Medicare Advantage plan that returns or rebated a portion of your Part B premium, when your income exceeds the IRMAA limits (such as $109,000 for an individual for 2026), you will need to pay Medicare Part D IRMAA (and Medicare Part B IRMAA).

Question:  What is IRMAA and who pays IRMAA?

If you are a Medicare beneficiary who earns a higher income, the government will assess an Income-Related Monthly Adjustment Amount (IRMAA) that you must pay in addition to your Medicare Part B premium and your Medicare Part D premium (if you are enrolled in a Medicare prescription drug plan (PDP) or Medicare Advantage plan that includes prescription drug coverage (MAPD)).

Question:  What happens if I do not pay my Part D IRMAA?

If you do not pay your Medicare Part D IRMAA, Medicare will notify your Medicare plan and your Part D plan can “involuntarily" disenroll you from your Medicare plan and you can be without prescription drug coverage for the remainder of the year unless you can use a Special Enrollment Period to join another Medicare Part D or Medicare Advantage plan.

Also, if you lose your Medicare Part D coverage, you may accumulate a permanent late-enrollment premium penalty for every month that you are without some form of creditable prescription drug coverage.
