What Medicare Costs Look Like When You Get SSDI

How Medicare premiums work when you receive SSDI

If you receive Social Security Disability Insurance (SSDI), you become covered by Medicare automatically after 24 months of receiving benefits. Your Medicare premiums are deducted directly from your SSDI payment each month — you do not pay them separately. The amount you pay depends on your income and which parts of Medicare you use.

Most SSDI recipients pay the standard Part B premium, which is the monthly charge for doctor visits and outpatient care. In 2024, this amount changes each year based on national healthcare costs. If your income is higher, you may pay an additional surcharge called an Income-Related Monthly Adjustment Amount (IRMAA), though most SSDI recipients do not reach the income threshold that triggers this.

Part A, which covers hospital stays, is free for almost all SSDI recipients. Part D, which covers prescription drugs, has its own premium that varies by plan — you choose which plan to join, and the cost depends on which one you pick.

Key Takeaways

• Medicare premiums for Part B are taken directly from your SSDI check each month, so you never write a separate check.
• Part A hospital coverage is free; Part B (doctor visits) has a monthly premium that applies to most SSDI recipients.
• Part D prescription drug coverage is optional and costs vary depending on which plan you choose through Medicare.
• If your income rises above certain thresholds, you may pay extra charges on top of the standard premium, though this is uncommon for SSDI recipients.
• Your costs stay the same whether you enroll in Original Medicare or a Medicare Advantage plan, though coverage and out-of-pocket costs differ between them.

What Part B costs and what it covers

Part B is the part of Medicare that covers doctor visits, lab tests, imaging, and outpatient procedures. The standard Part B premium is deducted from your SSDI payment automatically. The exact amount changes each January and is set by Medicare based on the previous year's costs.

Beyond the monthly premium, you also pay a yearly deductible before Part B coverage kicks in — this is a separate amount you must meet each calendar year. After you meet the deductible, you typically pay 20 percent of the cost for most services, and Medicare pays 80 percent. Some services, like preventive care, have no cost-sharing at all.

If your income is below a certain level, you may be covered by a program called Medicaid (run by your state, not Medicare), which can pay your Part B premium and deductible for you. Each state sets its own income limits, so whether you may have access to depends on where you live and how much you earn.

Part D prescription drug coverage and how to choose a plan

Part D is optional coverage for prescription medications. Unlike Part A and Part B, which are automatic, you must actively choose a Part D plan during your enrollment period. If you do not enroll when you first become covered by Medicare, you may face a permanent penalty on your premiums if you join later.

Part D plans are offered by private insurance companies approved by Medicare. Each plan has its own list of covered drugs, its own monthly premium, and its own rules about which pharmacies you can use. The premium you pay depends entirely on which plan you choose — some cost $5 per month, others cost $100 or more.

You can compare plans using Medicare's online tool, which shows you the total cost for your specific medications at different pharmacies. Many SSDI recipients with low income may have access to for Extra Help, a federal program that pays most or all of your Part D premium and reduces your out-of-pocket drug costs. You apply for Extra Help through Social Security, not through Medicare.

When your SSDI payment is reduced for Medicare costs

Your SSDI check is reduced by the amount of your Part B premium each month. This happens automatically — Social Security deducts it before the money reaches your bank account. If you also owe a Part D premium, that is not deducted from SSDI; instead, you pay it directly to your insurance plan, usually by mail or online.

The reduction in your SSDI payment is the same for everyone paying the standard Part B premium, regardless of how much SSDI you receive. If your SSDI payment is very small, the premium reduction may take a significant chunk of it. In that case, you may want to explore whether you may have access to for Medicaid in your state, which can cover the premium for you and reduce your out-of-pocket costs.

If you have questions about why a specific amount was deducted, you can call Social Security at 1-800-772-1213 and ask to speak with someone about your Medicare deduction. They can explain the exact breakdown of what was taken and why.

Income limits and extra charges (IRMAA)

If your income exceeds certain thresholds, Medicare charges you an additional monthly amount on top of the standard Part B premium. This surcharge is called an Income-Related Monthly Adjustment Amount (IRMAA). The income limits are fairly high for most SSDI recipients, so you typically only face IRMAA if you have substantial earnings from work or other income sources beyond your SSDI payment.

IRMAA is based on your income from two years prior. So in 2024, Medicare looks at your 2022 income to decide your 2024 premium. If your income changes significantly — for example, you return to work or lose a job — you can request that Medicare recalculate your IRMAA based on your current situation, rather than waiting two years for the automatic adjustment.

The surcharge applies to both Part B and Part D if your income is high enough. Most SSDI recipients do not pay IRMAA because their income stays below the threshold, but if you do, the extra amount is deducted from your SSDI check along with your standard premium.

Medicaid and how it reduces your Medicare costs

Medicaid is a separate program run by your state that covers low-income people. If you may have access to for Medicaid while you are on SSDI, Medicaid can pay your Medicare premiums and deductibles, which dramatically reduces your out-of-pocket costs. Some states also cover services that Medicare does not, like dental or vision care.

Each state sets its own income limits for Medicaid, so whether you may have access to depends on where you live. In some states, if you receive SSDI, you automatically may have access to for Medicaid. In others, you must have income below a specific amount. You apply for Medicaid through your state's Medicaid office or through your state's health insurance marketplace.

If you think you might may have access to, contact your state Medicaid office or call 211 to be connected to local resources. They can tell you the income limit in your state and help you understand whether you meet it. Having both Medicare and Medicaid is called "dual coverage," and it significantly reduces what you pay for healthcare.

Frequently Asked Questions

Does the Medicare premium come out of my SSDI check before or after I receive it?

The premium is deducted before the money reaches you. Social Security calculates your SSDI payment, subtracts the Medicare Part B premium, and deposits the remainder into your bank account. You see only the amount after the deduction.

What happens if I cannot afford the Medicare premium?

If your income is low enough, Medicaid in your state may pay the premium for you. You can also contact Social Security to discuss hardship options if the premium is creating genuine financial strain. Some people also may have access to for Extra Help with Part D costs, which reduces drug premiums and out-of-pocket expenses.

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

You can decline Part B when you first become covered by Medicare, but if you enroll later, you will face a permanent penalty on your premiums. Most people keep Part B because the penalty ends up costing more over time than the premium itself. If cost is the issue, exploring Medicaid or Extra Help is usually a better option.

How do I know which Part D plan is cheapest for my medications?

Use Medicare's Plan Finder tool on Medicare.gov. Enter your medications and preferred pharmacies, and it shows you the total annual cost for each plan. Plans change every year, so you should compare them again during the annual enrollment period (October 15 to December 7) even if you were happy with your plan last year.

What is Extra Help and how do I apply?

Extra Help is a federal program that pays most or all of your Part D premium if your income and resources are low. You apply through Social Security, not Medicare. Call 1-800-772-1213 or visit your local Social Security office with information about your income and savings, and they can tell you whether you may have access to.
