Medicare premiums are deducted directly from your SSDI payment each month

When you turn 65 or become may be able to access for Medicare while receiving SSDI, your Part B premium (which covers doctor visits and outpatient care) is automatically withheld from your monthly benefit check. The amount changes each year. For 2024, the standard Part B premium is $164.90 per month, though some people pay more based on their income from two years prior.

The withholding happens without you having to do anything — Social Security handles it automatically once you are enrolled in Medicare Part B. If you also choose to enroll in Part D (prescription drug coverage) or a Medicare Advantage plan, those premiums are deducted separately, either from your SSDI check or billed to you directly depending on the plan.

Part A (hospital insurance) has no monthly premium for most people who have worked long enough to may have access to, so nothing is withheld for it. However, if you did not work long enough to may have access to for premium-free Part A, you would pay a premium for that as well.

Key Takeaways

  • Part B premiums are deducted from your SSDI check automatically each month, reducing the amount you receive.
  • The standard 2024 Part B premium is $164.90 monthly, but the amount varies by year and by your income level from two years prior.
  • Part D and Medicare Advantage plan premiums are separate and may be deducted from SSDI or billed directly depending on which plan you choose.
  • You can see your exact premium amount on your Medicare Summary Notice, which Social Security mails to you each year.

Income-related premium increases and how they work

If your income from two years ago exceeded certain thresholds, Medicare charges you a higher Part B premium — called an Income-Related Monthly Adjustment Amount or IRMAA. Social Security uses your Modified Adjusted Gross Income (MAGI) from your tax return to calculate this, not your current SSDI amount.

For example, if you had other income in 2022 (such as wages, interest, or rental income), that income determines your 2024 premium. The income brackets and premium amounts change each year. If your income was below the threshold, you pay the standard premium. If it was above, you pay more — sometimes significantly more.

If your income drops — because you stopped working, received a one-time payment, or had a life event like divorce or death of a spouse — you can ask Social Security to recalculate your IRMAA. This is called a life-changing event appeal, and it may lower your premium for the remainder of that year.

What happens if you cannot afford the premium

If the Part B premium withheld from your SSDI check leaves you with too little to live on, you have options. You can request that Social Security reduce or delay your Part B premium withholding through a process called a hardship exemption. This is not the same as cancelling Medicare — you stay enrolled, but the premium is not taken from your check.

To request this, contact Social Security directly at 1-800-772-1213 or visit your local Social Security office. You will need to explain your financial hardship and may be asked to provide proof of your expenses and income. Social Security reviews these requests case by case.

Another option is to enroll in a Medicare Savings Program (MSP) run by your state. These programs help pay your Part B premium, deductibles, and copayments if your income and resources fall below certain limits. Each state sets its own limits, so what qualifies in one state may not in another. You explore through your state's Medicaid office, not through Medicare.

How to find your exact premium amount

Your Medicare premium appears on your Medicare Summary Notice, which Social Security sends to you each December. This notice shows your Part B premium for the coming year, any IRMAA adjustment, and the total amount that will be withheld from your SSDI check starting in January.

You can also log into your Medicare.gov account to see your current premium information, or call Medicare directly at 1-800-MEDICARE (1-800-633-4227). If you notice an error on your notice — such as an income amount that is wrong — you have a limited window to appeal it, usually until March 31 of that year.

If you receive a notice showing a premium increase you did not expect, read it carefully to see whether it is due to a standard annual increase or an IRMAA adjustment. The reason matters because the steps to challenge it are different.

Part D and Medicare Advantage premiums

If you enroll in a Part D plan (prescription drug coverage), the monthly premium for that plan is separate from your Part B premium. Some Part D plans cost nothing, while others charge $5 to $100+ per month depending on the plan and the drugs it covers. These premiums are usually deducted from your SSDI check if you choose that option when you enroll.

A Medicare Advantage plan (Part C) replaces Original Medicare and includes drug coverage. Many Advantage plans have no monthly premium, though you still pay your Part B premium to Social Security. Others charge an additional premium on top of Part B. Advantage plans also have different deductibles and copayments than Original Medicare, so the total cost to you depends on how much medical care you use.

When you first become may be able to access for Medicare, you have a limited time to enroll in Part D without penalty. If you miss that window and enroll later, you may pay a permanent penalty on top of your regular premium. This is one reason to review your options carefully during your initial enrollment period.

What changes your premium amount

Your Part B premium can change for three main reasons: a standard annual increase set by Medicare, an IRMAA adjustment based on your income from two years prior, or a change in your enrollment status (such as dropping or adding Part D).

Standard increases happen most years and are announced in the fall for the coming year. IRMAA adjustments happen automatically if your income crossed a threshold — you do not have to do anything for this to occur, though you can appeal if your income has since dropped. Changes in your enrollment status take effect the month after you make the change.

Your SSDI amount itself does not affect your Medicare premium. Only your income from work, investments, and other sources matters for IRMAA purposes. This means you could receive a large SSDI increase and still pay the same Medicare premium, or a small SSDI increase and face a higher premium if your other income was high two years ago.

Frequently Asked Questions

Can I refuse Medicare Part B to keep my full SSDI check?

No. Once you turn 65, you are automatically enrolled in Medicare Part B, and the premium is withheld from your SSDI check. You can decline Part B enrollment before it starts, but this is rarely advisable because you will face a permanent penalty if you enroll later. The only exception is if you are still working and covered by an employer health plan.

What if I disagree with the income amount Social Security used to calculate my IRMAA?

You can file an appeal called a life-changing event appeal if your income has dropped since the year Social Security used to calculate your premium. You have until March 31 of that year to file. You will need to provide proof of the change, such as a job loss letter or divorce decree. Contact Social Security or Medicare to start the appeal.

Do I pay Medicare premiums if I am on SSDI and under 65?

No. You do not pay Medicare premiums until you turn 65, even though you may be enrolled in Medicare. If you are under 65 and on SSDI, you become may be able to access for Medicare automatically after 24 months of receiving SSDI benefits, but no premium is withheld until you reach 65.

Can my state help pay my Medicare premiums?

Yes, through a Medicare Savings Program. These state-run programs help pay your Part B premium, deductibles, and copayments if your income is low enough. Income limits vary by state. You explore through your state's Medicaid office, not Medicare. Call 1-800-MEDICARE to find your state's program.

What happens to my Medicare if I go back to work?

Your Medicare coverage continues, and you keep paying the same premiums. However, if you earn enough income to affect your MAGI, your IRMAA may increase two years later. Your SSDI benefits may also change or stop depending on how much you earn, but your Medicare stays in place as long as you remain enrolled.
