I have VA benefits and do not have Medicare drug coverage, so why am I being charged IRMAA when I am not even enrolled in a Part D plan?

IRMAA: Higher incomes and costs · updated Nov 15, 2025

You are probably not being charged for Medicare Part D IRMAA, but rather only Medicare Part B IRMAA.

Income-Related Monthly Adjustments Amounts (IRMAA) are additional amounts of money charged to Medicare beneficiaries who have annual income (modified adjusted gross income (MAGI)) over certain limits.

The IRMAA charges are then paid in addition to both Medicare Part B and Medicare Part D premiums.

You can see the annual changes in IRMAA limits in our this site News section.

However, Part D IRMAA will not be charged if you are not enrolled in a Medicare Part D plan - but, you will still need to pay your Medicare Part B IRMAA. 

As noted by the Centers for Medicare and Medicaid Services (CMS):
"If an individual does not have or no longer has Medicare prescription drug coverage, they shouldn’t be charged the Part D-IRMAA."  However, the CMS memo does continue on to note that "if someone didn’t pay the Part D-IRMAA that was owed before disenrolling from their prescription drug coverage, they are responsible for the past due amount."

2026 Example of IRMAA without drug coverage:  "I have VA drug benefits and no Part D plan, so why am I being charged $81.20 for IRMAA?"

You are paying only Part B IRMAA.  Using this 2026 example, the Medicare Part B IRMAA is $81.20 for couples who earn between $218,000 up to $274,000 annually or individuals who earn $109,000 up to $137,000.

During the same year, the Medicare Part D IRMAA is $14.50 for the same income bracket (couples who earn between $218,000 up to $274,000 annually or individuals who earn $109,000 up to $137,000).

Since this person is assessed $81.20, and does not have a Medicare Part D prescription drug plan, they are only being charged for their Part B IRMAA.
