What is IRMAA and why is it deducted from my Social Security?

Since 2007, Medicare members whose taxable income exceeds a certain threshold have been charged more than the standard Part B and Part D monthly premiums, in accordance with a surcharge schedule. The acronym for that extra charge is IRMAA, which stands for Income Related Monthly Adjustment Amount. This year the income threshold is $85,000 for individuals and $170,000 for couples filing joint tax returns. 

The NYC Health Benefits Program will reimburse the amount of the Medicare Part B IRMAA increase. The reimbursement claim form and instructions are available in the Forms section of this website. However, the IRMAA surcharge for Medicare Part D is not reimbursed.

The rules and rates for Higher-Income Medicare Beneficiaries are available on the Social Security Administration website here.
