Yes, but not right away and not automatically

Social Security Disability Insurance (SSDI) does include health insurance, but you have to wait for it. When you start receiving SSDI payments, you are not covered by Medicare when ready. Instead, you begin with a waiting period: you must receive SSDI for 24 months before Medicare coverage begins. During those first two years, you need to find health coverage elsewhere — through a spouse's employer, Medicaid, the Affordable Care Act marketplace, or another source.

After 24 months on SSDI, Medicare Part A (hospital insurance) and Part B (medical insurance) start automatically. You do not have to explore separately or do anything to set up it. The Social Security Administration handles the enrollment. This is different from how Medicare works for people who reach age 65, where you must actively enroll during a specific window or face penalties.

Some people on SSDI also stay on Medicaid at the same time. Whether you keep Medicaid after Medicare starts depends on your state's rules and your income. Medicaid can cover costs that Medicare does not — like long-term care, dental, and vision — so losing it can matter significantly.

Key Takeaways

  • SSDI recipients receive Medicare Part A and Part B automatically after 24 months on the program, with no separate enrollment step required.
  • During the first 24 months of SSDI, you must find health coverage through Medicaid, a spouse's plan, the ACA marketplace, or another source.
  • You may stay on Medicaid even after Medicare begins, depending on your state and income level.
  • Medicare premiums for SSDI recipients are usually deducted directly from your monthly SSDI payment.
  • Certain work incentives allow you to keep Medicare coverage for a limited time even if you return to work and your SSDI payments stop.

The 24-month waiting period and what to do during it

The 24 months starts from the month you begin receiving SSDI payments, not from the month you applied or were approved. If you were approved in March but your first payment came in May, the 24-month clock starts in May. This matters because it affects when your Medicare coverage actually begins.

During this waiting period, you have several options. If you have a spouse who works, you may be able to join their employer health plan. If your income is low enough, you can explore for Medicaid through your state — Medicaid does not have a waiting period and covers many services Medicare does not. You can also shop for coverage on the Affordable Care Act marketplace at Healthcare.gov. Some people may have access to for subsidies that lower their monthly premiums based on their SSDI income.

Do not wait until month 24 to think about coverage. If you have a gap in health insurance, you risk owing large medical bills out of pocket. Some people find that staying on Medicaid during the waiting period and keeping it after Medicare starts is the best option because Medicaid covers services like dental and vision that Medicare does not.

How Medicare Part A and Part B work for SSDI recipients

Medicare Part A covers hospital stays, skilled nursing facility care, hospice, and some home health services. Part B covers doctor visits, outpatient care, lab tests, and durable medical equipment. Both are included in your SSDI Medicare coverage at no separate enrollment step.

You will pay a monthly premium for Part B, which is deducted automatically from your SSDI payment. The standard Part B premium changes each year — it was $164.90 per month in 2024, but this amount varies by income and changes annually. If your income is higher, you may pay an income-related monthly adjustment amount (IRMAA) on top of the standard premium. Part A has no monthly premium for most SSDI recipients.

Medicare has deductibles and copayments. For Part A, you pay a deductible for each hospital stay. For Part B, you pay a deductible once per year, then 20 percent of the cost of most services after that. These costs can add up, which is why many people on SSDI also keep Medicaid or buy a Medigap supplemental policy to cover what Medicare does not.

Medicaid and SSDI: how they work together

Medicaid is a separate program run by states, not the federal government. When you receive SSDI, you do not automatically get Medicaid — you have to explore through your state. However, in most states, receiving SSDI makes you categorically may be able to access for Medicaid, meaning you meet the income and disability requirements automatically. You still have to submit an process, but the process is usually faster than for people who do not receive SSDI.

Some states have different Medicaid rules. A few states do not use categorical may be able to access for SSDI recipients, so you may have to prove your income and resources separately. A handful of states have higher income limits for Medicaid than the SSDI payment amount, so you might not may have access to even though you receive SSDI. Your state Medicaid office can tell you whether you are may be able to access based on your SSDI status alone.

If you are on both Medicaid and Medicare, Medicaid is called the "secondary payer." This means Medicare pays first, and Medicaid covers costs that Medicare does not — copayments, deductibles, and services like dental and vision. This combination is often called "dual may be able to access" status and can significantly reduce your out-of-pocket costs.

What happens to your health insurance if you work

SSDI includes work incentives that let you test whether you can work without losing your entire benefit. The most important one for health insurance is called Medicare Continuation. If your SSDI payments stop because you earn too much money, you can keep Medicare Part A and Part B for up to 93 months (about 7.75 years) by paying the monthly premium yourself.

This is valuable because it means you do not have to rush to find employer coverage or worry that a gap in work will leave you uninsured. You can work, lose SSDI, keep Medicare, and if work does not work out, you can reapply for SSDI without waiting another 24 months for Medicare to restart.

Medicaid rules for people who work are different and vary by state. Some states let you keep Medicaid if your income stays below a certain threshold. Others have work incentive programs that let you earn more and still keep Medicaid. Contact your state Medicaid office or a work incentive planning and information (WIPA) project to understand what applies to you.

Costs and coverage gaps to watch for

Medicare does not cover everything. Dental, vision, hearing aids, and long-term custodial care are not covered by Part A or Part B. If you lose Medicaid when Medicare starts, you will have to pay for these services out of pocket or buy a private Medigap policy. Medigap policies are sold by private insurers and cover some of the costs that Medicare does not — but they do not cover dental or vision either.

Your SSDI payment is reduced by your Part B premium, so your take-home benefit is smaller than the full SSDI amount. If you also have to pay for Medigap or out-of-pocket costs, your budget can become tight. Some people find that keeping Medicaid is worth staying below certain income thresholds because Medicaid covers services Medicare does not.

If you work and lose SSDI, your Medicare Continuation coverage requires you to pay the full Part B premium yourself — there is no employer subsidy. This can be expensive if you are not earning much. Plan ahead by understanding what your costs will be if your work situation changes.

How to enroll and what documents you need

You do not enroll in Medicare for SSDI — the Social Security Administration does it for you automatically after 24 months. About three months before your Medicare coverage starts, you will receive a notice in the mail explaining your coverage and your Part B premium amount. Your Medicare card will arrive in the mail before your coverage begins.

For Medicaid, you must explore through your state. You can explore online through your state's Medicaid website, by mail, or in person at your local Medicaid office. You will need proof of your SSDI status (your benefit letter or Social Security statement), proof of income, and proof of residency. The process usually takes 30 to 45 days.

If you want coverage during the 24-month waiting period, explore for Medicaid or ACA marketplace coverage as soon as your SSDI payments begin. Do not wait. If you have a gap in coverage, you may owe medical bills that you cannot pay back.

Frequently Asked Questions

Do I have to pay for Medicare if I am on SSDI?
