Most Medicare prescription drug (Part D) plans charge a monthly premium which vary by plan.  If your modified adjusted gross income as reported on your IRS tax return from 2 years ago (the most recent tax return information provided to Social Security by the IRS) is above a certain limit, you may pay a Part D income-related monthly adjustment amount (Part D-IRMAA) in addition to your monthly plan premium. This extra amount is paid directly to Medicare, not to your plan.

Social Security will contact you if you have to pay Part D-IRMAA, based on your income.  The amount you pay can change each year.  If you have to pay a higher amount for your Part D premium and you disagree (for example, if your income goes down), you can contact Social Security to request a reduction in your income-related monthly adjustment amount.

Note: The extra amount you have to pay isn’t part of your plan premium. Therefore, you don’t pay the extra amount to your plan, but instead directly to Medicare. Most people have the extra amount taken from their Social Security check. If the amount isn’t taken from your check, you’ll get a bill from Medicare. You must pay this amount to keep your Part D coverage. There are several ways to pay your Part D IRMAA – find out how to pay your bill.
