How to Appeal an IRMAA Determination

Tax Planning Retirement Planning Financial Planning


The Income-Related Monthly Adjustment Amount (IRMAA) is a component of Medicare Part B and Part D premiums that is determined based on an individual's income. IRMAA notices usually come out near the end of the year, stating what your new Medicare premium will be for the next year.

While Medicare is an essential healthcare program for many Americans, an IRMAA determination can lead to increased costs for higher-income beneficiaries. However, the determination of IRMAA is not set in stone. If you believe that your IRMAA determination is incorrect or unjust, you have the right to appeal the decision. In this article, we'll guide you through the process of appealing an IRMAA determination.

Understanding IRMAA

Before delving into the appeals process, it's important to understand what IRMAA is and how it's calculated. IRMAA is an additional premium that higher-income Medicare beneficiaries are required to pay for Medicare Part B and Part D coverage. The determination is based on your modified adjusted gross income (MAGI), which is calculated from your tax return from two years prior. If you've experienced a life-changing event that significantly impacted your income, such as retirement or the death of a spouse, you can request a re-evaluation of your IRMAA determination.

Reasons to Appeal

There are several valid reasons for appealing an IRMAA determination:

  • Incorrect Information: Your IRMAA determination might be based on inaccurate or outdated income information.
  • Life-Changing Events may qualify you for a lower IRMAA. Here are some examples:
    • Marriage-You entered into a legal marriage. 
    • Divorce/Annulment-Your legal marriage ended, and you will not file a joint tax return for the year. 
    • Death of your spouse-Your spouse died. 
    • Work Stoppage-You or your spouse stopped working. 
    • Work Reduction-You or your spouse reduced your work hours. 
    • Loss of Income-Producing Property-You or your spouse experienced a loss of income-producing property not under your control.  Examples of this would include disaster, losing property due to arson, fraud, or theft. 
    • Loss of Pension Income-You or your spouse experienced some sort of disruption (cessation, termination, or reorganization) of an employer’s pension plan. 
    • Employer Settlement Payment-You or your spouse receive a settlement from your employer/former employer. 
  • Retroactive Application: If you're appealing based on a life-changing event, you may be able to have your IRMAA adjustment applied retroactively to a previous year.
  • Administrative Errors: Mistakes can happen during the calculation and notification process, leading to an incorrect determination.

Steps to Appeal

Appealing an IRMAA determination involves several steps:

Review the Determination Letter: The first step is to carefully review the IRMAA determination letter you received from the Social Security Administration (SSA). This letter will outline the basis for your IRMAA and provide information on how to appeal.

Gather Documentation: Collect all necessary documentation to support your appeal. This may include tax returns, proof of life-changing events, and any other relevant financial documents.

Complete the Appeal Form: The SSA provides Form SSA-44 (Medicare Income-Related Monthly Adjustment Amount-Life-Changing Event) for appealing IRMAA determinations based on life-changing events. You’ll be surprised how informative this form actually is, so read it carefully. Fill out this form accurately and provide supporting documentation. Please note that if there are two spouses on Medicare you’ll probably each receive an IRMAA determination letter and will each need to complete an appeal form.

Submit the Appeal: Send your completed appeal form and supporting documents to the SSA. Make sure to keep copies for your records and consider sending the documents through certified mail to ensure they are received.

Await Response: The SSA will review your appeal and respond with a decision. This process can take some time, so be patient.

Appeal Further, If Necessary: If your appeal is denied and you believe there was an error or misunderstanding, you have the right to request a reconsideration or a hearing.


Appealing an IRMAA determination can be a complex process, but it's essential if you believe your determination is inaccurate or unjust. Understanding the reasons for appealing and following the steps outlined in this article can help you navigate the process successfully. Remember to gather all relevant documentation, complete the necessary forms, and be prepared to wait for a response from the SSA. Your efforts can result in a fairer and more accurate determination of your IRMAA, ensuring that your Medicare costs align with your actual income.
