How to Appeal Your Medicare Part B Premium (IRMAA)

By Brian Krantz - December 1, 2025

How to appeal IRMAA surcharges and lower my Medicare Part B premium.

If you’ve received a Medicare IRMAA determination letter and believe the Income-Related Monthly Adjustment Amount (IRMAA) surcharge is incorrect, you have the right to file an IRMAA appeal. The Social Security Administration (SSA) calculates your Medicare Part B premium and Part D premiums based on your modified adjusted gross income (MAGI) from your IRS tax return. High-income brackets can trigger a higher premium and IRMAA surcharge, but certain life-changing events may qualify you for a lower premium amount.

Step 1: Request a Reconsideration

Start the appeals process by requesting a reconsideration of the initial determination.

  • Call the SSA at 1-800-772-1213 or visit your local Social Security office.
  • Complete Form SSA-44 (Life-Changing Event Form) or submit a completed form SSA-44 online: Download here.
    This form helps document your life-changing event and updated tax information.

Step 2: Qualifying Reasons for a New Determination

You may qualify for a new IRMAA decision if:

  • Your income tax return was inaccurate or outdated (and you filed an amended tax return).
  • There was an error in IRS data or SSA used older tax information.
  • You had a drop in income due to a life-changing event affecting your MAGI.

Seven qualifying life-changing events include:

  1. Death of a spouse
  2. Marriage or annulment
  3. Divorce
  4. Work reduction or work stoppage
  5. Loss of income-producing property
  6. Loss or reduction of certain pension income
  7. Settlement payment or other significant income changes

Step 3: Be Patient and Persistent

The Part B premium appeals process can take several months. SSA may request supporting documents such as W-2s, tax returns, or proof of income. Providing accurate documentation promptly is key.

Important Notes

  • Medicare beneficiaries with higher-income brackets often face IRMAA surcharges for both Medicare Part B and Part D plans.
  • Your premium amount is based on MAGI, which includes tax-exempt interest.
  • If your income changed due to COVID-19 or another life-changing event, you may qualify for a new determination.
  • IRMAA applies to Original Medicare, Medicare Advantage plans, and prescription drug coverage under Part D.
