Medicare premiums come out of your SSDI check, and the amount depends on your income

When you receive both SSDI and Medicare, your monthly SSDI payment is reduced by the amount you owe for Medicare Part B (medical insurance) and Part D (prescription drug coverage). This is called a premium deduction. The Social Security Administration takes the money directly from your benefit before you receive it, so you never see that portion of your check.

The size of your premium depends on your income from the previous year. If your income was higher two years ago, you may pay more now — Social Security uses a delayed calculation called income-related monthly adjustment amounts, or IRMAA. This means a change in your earnings or other income today will affect your premiums about two years from now.

Part A (hospital insurance) has no monthly premium for most people on SSDI, because SSDI recipients are automatically considered to have paid enough into Social Security to may have access to. However, you may owe a deductible when you use the hospital, and that works separately from your monthly premium.

Key Takeaways

  • Medicare Part B and Part D premiums are subtracted from your SSDI payment each month, reducing the amount you receive in your bank account.
  • Your premium amount is based on your income from two years prior, so a job or other income you had in the past affects what you pay now.
  • If your income drops significantly, you can ask Social Security to recalculate your premiums using current-year income instead of the delayed figure.
  • Part A typically has no monthly premium for SSDI recipients, but you will still owe hospital deductibles when you use inpatient care.
  • Your SSDI check will show the premium deduction as a separate line item, so you can see exactly what Medicare is costing you each month.

How the premium deduction appears on your SSDI payment

Your SSDI benefit statement shows three numbers: your gross benefit (the full amount you earned), the Medicare premium deduction, and your net payment (what actually reaches your bank account). If you receive $1,200 in SSDI and your Part B premium is $164.90, your net check is $1,035.10.

You can see this breakdown in your Social Security statement, which you receive by mail or can view online through your my Social Security account. The statement lists your gross benefit, each deduction (Medicare Part B, Part D, and any others), and your net amount. If the deduction seems wrong, this statement is your proof to bring when you contact Social Security.

The premium deduction happens automatically once you enroll in Medicare Part B and Part D. You do not need to pay Medicare directly — Social Security handles it. If you decline Part D when you first become may be able to access for Medicare, you can enroll later, but you may owe a penalty that increases your premium permanently.

When your income changes and premiums need to recalculation

Social Security uses your Modified Adjusted Gross Income (MAGI) from two years ago to set your current premiums. If you earned $25,000 in 2022, that income determines your 2024 premiums. This delay means you might pay higher premiums now based on work you no longer do.

If your income has dropped significantly — you stopped working, lost a job, or had a major life change — you can ask Social Security to recalculate your premiums using your current-year income instead. This is called a life-changing event request. You must contact Social Security and explain the change, and they will review whether it qualifies. Common may have access to events include loss of employment, reduction in work hours, or death of a spouse who contributed to household income.

To request a recalculation, call Social Security at 1-800-772-1213 or visit your local Social Security office. Bring documentation of the income change — a termination letter from your employer, recent pay stubs showing reduced hours, or tax documents. The process typically takes two to four weeks.

Part B premiums and income thresholds

In 2024, the standard Part B premium is $164.90 per month for most people. However, if your MAGI exceeds certain thresholds, you pay a higher amount. The thresholds are different depending on whether you file taxes as single, married filing jointly, or married filing separately.

For 2024, if you are single and your MAGI is over $97,000, your Part B premium increases. If you are married filing jointly and your MAGI is over $194,000, your premium increases. The higher your income above the threshold, the more you pay — there are five income brackets, and the highest earners pay roughly three times the standard premium.

These thresholds and premium amounts change each year. Social Security sends you a notice in October or November if your premiums will change for the following year. If you disagree with the amount, you have 60 days from the date on the notice to request a review.

Part D premiums and how they work with SSDI

Part D is prescription drug coverage, and the premium varies depending on which plan you choose. Unlike Part B, there is no single standard Part D premium — each insurance company that offers Part D sets its own price. Plans range from roughly $5 to $100 per month, depending on the coverage level and the company.

You choose your Part D plan during the initial enrollment period when you first become may be able to access for Medicare, or during the annual open enrollment period in October and November. If you do not enroll in Part D when you first become may be able to access, you will owe a late enrollment penalty for as long as you have Part D coverage. The penalty is roughly 1% of the national average Part D premium for each month you delayed, and it increases your premium permanently.

Your Part D premium is also subject to income-related adjustments, similar to Part B. If your income is high enough, you will pay an additional surcharge on top of your plan's base premium. Social Security deducts both the base premium and any income-related surcharge from your SSDI check.

What happens if your SSDI payment is very small

If your SSDI benefit is smaller than your Medicare premiums, Social Security will still deduct the full premium amount. This can result in a net payment of zero or even a negative balance, which means you owe money to Social Security.

In practice, this is rare. Most people on SSDI receive enough to cover Medicare premiums. However, if you are in this situation, contact Social Security when ready. They can review whether you are enrolled in the right Medicare plans, whether you may have access to for Extra Help (a program that pays Part D premiums for people with low income), or whether other information programs are available to you.

Extra Help is a federal program that covers Part D premiums and cost-sharing for people whose income and resources fall below certain limits. If you think you might may have access to, you can explore through Social Security or through your state Medicaid office. The income limits are higher than regular Medicaid, so you may may have access to even if you do not may have access to for other information.

How to review and dispute your premium amount

Start by checking your Social Security statement online or by phone. Call 1-800-772-1213 and ask for a detailed breakdown of your current premiums and the income figure Social Security used to calculate them. Write down the date you call and the name of the representative, in case you need to follow up.

If the income figure is wrong — for example, Social Security used 2022 income when you had no income in 2022 — request a recalculation. Bring tax documents, W-2 forms, or other proof of your actual income for that year. If Social Security made an error, they will correct it and may owe you a refund of overpaid premiums.

If you disagree with Social Security's decision about your premium or your recalculation request, you have the right to appeal. The appeal process has several levels: reconsideration, hearing before an administrative law judge, and review by the Appeals Council. You do not need a lawyer, but many people find it helpful to have one, especially at the hearing stage.

Frequently Asked Questions

Can I opt out of Medicare Part B to keep more of my SSDI check?

You can decline Part B when you first become may be able to access for Medicare, but once you enroll, you cannot drop it without penalty. If you later want to re-enroll, you will owe a permanent surcharge on your premium. Most people on SSDI should enroll in Part B because the coverage is valuable and the premium is relatively low compared to private insurance.

What if I go back to work and my income increases?

Your Medicare premiums will not change when ready. Social Security uses income from two years ago, so a job you start today will affect your premiums in 2026. When that happens, your premiums may increase. If your income later drops again, you can request a recalculation based on current income.

Does my spouse's income affect my Medicare premiums?

Only if you file taxes jointly. Social Security uses your Modified Adjusted Gross Income (MAGI) to calculate premiums. If you are married and file jointly, your combined income is used. If you file separately, only your individual income counts, but filing separately may result in higher premiums for both of you.

Can I get a refund if I overpaid Medicare premiums?

Yes, if Social Security made an error in calculating your premiums or if your income was lower than they thought. Request a review of your account and provide proof of your actual income. If an overpayment is confirmed, Social Security will refund it, usually by increasing your next several SSDI checks.

What is the difference between Part B and Part D premiums?

Part B covers doctor visits, outpatient care, and medical equipment. Part D covers prescription drugs. Part B has a standard premium set by the government each year. Part D premiums vary by plan and insurance company. Both are deducted from your SSDI check, and both are subject to income-related increases if your income is high enough.
