IRMAA stands for income-related monthly adjustment amount. Similar to Medicare Part B, high-income earners will pay more for their Medicare Part D coverage.
If you are a member of a Medicare plan that includes prescription drug coverage and your modified adjusted gross income on your IRS tax return from 2 years ago is above a certain limit, you may pay an additional amount for Medicare Part D coverage. The extra amount is paid directly to Social Security, not to your plan. If you are subject to IRMAA, Social Security will send you a letter. The letter will explain how they determined the amount you must pay and the actual IRMAA.
Neither APWU Health Plan nor your health plan determine who will be subject to IRMAA. Therefore, if you disagree with the amount you must pay, contact the Social Security Administration:
