Since 2011, people with Medicare who earn over $85,000 have been paying an additional monthly premium or Income-Related Monthly Adjustment Amount (IRMAA) for their
Medicare Part D prescription drug plan coverage.
Section 1860D-13(a)(7) of the Social Security Act requires that beneficiary’s with a "modified adjusted gross income" (MAGI) greater than the specified threshold amounts ($85,000 in 2019 for a beneficiary filing an individual income tax return or married and filing a separate return, and $170,000 for a beneficiary filing a joint tax return), are responsible for a larger portion of the total cost of Part D their benefit coverage and should pay back a portion of the cost via the Income-Related Monthly Adjustment Amount (IRMAA).
In 2019, most high-earning Medicare Part D members will see about a 5% decrease in their Part D IRMAA payments as compared to their current 2018 payments - assuming their income remains consistent. However, people in the "new" highest income bracket (individuals earning over $500,000 and couples earning over $750,000) will notice a 3.5% increase in their IRMAA payments over 2018 levels.
Medicare Part D IRMAA charged for PDPs and MAPDs
If you are one of these higher-earning Medicare beneficiaries, you will find that Part D IRMAA payments are required whether you receive your Medicare Part D coverage
through a stand-alone Medicare Part D plan (PDP)
or through a Medicare Advantage plan that includes prescription drug coverage (MAPD).
Medicare Part D IRMAA and Medicare Part B IRMAA
In addition, people with Medicare who have higher incomes also pay a separate IRMAA for their
Medicare Part B (out-patient) coverage. Please see the Medicare Part B section below for more information on Medicare Part B IRMAA.
A new income bracket for 2019 Medicare Part D and Medicare Part B IRMAA
In 2011, Medicare Part D IRMAA payments were determined using five (5) income brackets (levels). The Medicare Access and
CHIP Reauthorization Act of 2015 (the "Doc Fix" law) made adjustments to the five income brackets--Medicare Part D beneficiaries formerly in Part D IRMAA level four (4) were merged into level five (5) and level three (3) was split into level three (3) and level four (4).
In 2019, a sixth income bracket will be added to the IRMAA payment levels.
These income bracket changes can be seen in the following chart and resulted in some people paid considerably higher IRMAA in 2018 (up to a 58% increase in IRMAA) as compared to 2017 (These bracket changes also applied to Part B IRMAA (Part B section below).

A few important notes and reminders about IRMAA:
- The additional monthly Part D income-related adjustment amount is not collected by the Medicare Part D plans, but instead paid directly to the Federal government.
- 2019 IRMAA is calculated using the most recent tax returns available to the IRS - for 2019, this would be your 2017 tax returns that were filed in 2018.
- "Income" for purposes of IRMAA is defined as MAGI or Modified Adjusted Gross Income. MAGI is calculated as your total adjusted gross income (AGI) and tax-exempt interest income.
- The amount of your IRMAA will be directly deducted from your Social Security, Railroad Retirement Board, or Office of Personnel Management benefits.
- If there are not sufficient funds in your government benefits, then Medicare will bill you directly for the unpaid balance of your IRMAA payment.
- Medicare Part D beneficiaries affected by the 2019 IRMAA will receive a letter from the Social Security Administration notifying them of their IRMAA payment.
- If you do not pay your IRMAA, you will be involuntarily disenrolled from your Medicare Part D or Medicare Advantage plan - and may be without Medicare plan coverage for the remainder of the year.
As background, Medicare Part D IRMAA payments can change every year and are calculated using the
annually-released standard base Medicare Part D premium.
The 2019 standard base premium is $33.19, a decrease of $1.83 (-5.23%) or roughly
5% lower than the 2018 standard base premium.
