Are you facing an unexpected Income-Related Monthly Adjustment Amount (IRMAA) on your Medicare premiums? You’re not alone. Many Medicare beneficiaries are surprised when they receive notice of higher premiums due to IRMAA charges.
IRMAA is an additional charge applied to Medicare Part B and Part D premiums for individuals with higher incomes. While the Social Security Administration (SSA) calculates these charges based on past tax returns, many beneficiaries find themselves in situations where their income has changed significantly since the reported tax year. Fortunately, if you believe your IRMAA determination is incorrect or unfair, you have the right to appeal.
This article will teach you how to understand and appeal Medicare IRMAA. We’ll first explain what Medicare IRMAA is, how it’s calculated, who is affected by it, then teach you how to appeal it. Let’s get started.
How Medicare Premiums Work
Medicare is a federal health insurance program for individuals aged 65 and older and certain younger individuals with disabilities. While Medicare Part A is typically free for those who have paid sufficient payroll taxes, Part B (medical insurance) and Part D (prescription drug coverage) require monthly premiums.
The standard Part B premium is set annually by the government. However, some beneficiaries must pay higher premiums due to their income level. This is where the IRMAA comes into play. If your income exceeds certain thresholds, you will pay more for Medicare Part B and Part D than the standard premium amount.
What Is IRMAA?
IRMAA is an additional premium charged to higher-income Medicare beneficiaries for their Part B and Part D coverage. While most people pay the standard Medicare premium, IRMAA adds an extra charge for those whose income exceeds certain thresholds.
Key facts about IRMAA:
- Applies to both Medicare Part B (medical insurance) and Part D (prescription drug coverage)
- Calculated based on your modified adjusted gross income (MAGI) from two years prior
- Reassessed annually by the Social Security Administration (SSA)
- Can significantly increase your monthly Medicare costs
How Is an IRMAA Calculated according to your Adjusted Gross Income?
The Social Security Administration determines your IRMAA by reviewing your tax return from two years ago. For 2025 Medicare premiums, the SSA uses your 2023 tax information.
IRMAA calculations use your modified adjusted gross income (MAGI), which includes:
- Your adjusted gross income (AGI) from your tax return
- Tax-exempt interest income
- Any foreign-earned income excluded from taxation
If your MAGI exceeds specific income thresholds, you’ll be placed in a higher premium bracket. In 2023, individuals with MAGI above $97,000 or married couples filing jointly with MAGI above $194,000 became subject to IRMAA charges.
5 Valid Reasons to Appeal Your IRMAA
If you believe your IRMAA determination is incorrect or no longer reflects your financial situation, you can request a reconsideration. Here are legitimate reasons to appeal:
1. Life-Changing Events
Significant life events that reduce your income may qualify you for an IRMAA adjustment:
- Retirement or reduction in work hours
- Death of a spouse
- Divorce or marriage annulment
- Loss of income-producing property due to natural disaster
- Loss of pension income
- Employer settlement payments
2. Incorrect Tax Information
The IRS may have provided inaccurate tax data to the SSA, resulting in an incorrect IRMAA calculation.
3. Amended Tax Return
If you filed an amended tax return after the SSA calculated your IRMAA, you may qualify for a reconsideration.
4. Changes in Filing Status
A change in your tax filing status might affect your IRMAA eligibility.
5. One-Time Income Spike
A one-time increase in income (like selling property or taking a retirement distribution) that doesn’t represent your regular income level.
How to Appeal an IRMAA Decision: The Complete Process
Step 1: Obtain the Required Forms
To appeal an IRMAA determination, you’ll need Form SSA-44 (Medicare Income-Related Monthly Adjustment Amount – Life-Changing Event). This official social security form allows you to report significant income changes and request an IRMAA reassessment.
Step 2: Gather Supporting Documentation
Strong evidence is crucial for a successful appeal. Collect documents that prove your financial situation has changed:
- Employer letter confirming retirement or reduced hours
- Death certificate or divorce decree
- Recent tax returns and income statements
- Amended tax return documentation
- Evidence of property loss due to natural disaster
- Documentation of pension loss
Step 3: Submit Your IRMAA Appeal
You can file your appeal through multiple channels:
- Visit your local Social Security office in person
- Mail completed Form SSA-44 with supporting documents to the SSA
- Call the SSA at 1-800-772-1213 to discuss appeal options
Step 4: Follow Up on Your Appeal Status
The SSA will review your appeal and notify you of their decision. If approved, your IRMAA charges will be adjusted accordingly. If denied, you have additional recourse options.
What Happens If Your IRMAA Appeal Is Denied?
If your initial appeal is unsuccessful, you still have options:
- Request Reconsideration: Ask the SSA to review your case again.
- Administrative Law Judge (ALJ) Hearing: If reconsideration fails, request a hearing with an ALJ.
- Appeals Council Review: If denied by the ALJ, seek review by the Social Security Appeals Council.
- Federal Court Review: As a last resort, take your case to federal court.
