Yes, but not right away

If you receive Social Security Disability Insurance (SSDI), you will eventually get Medicare—but there is a waiting period. You become covered for Medicare after you have been on SSDI for 24 consecutive months. That 24-month clock starts from the month your SSDI payments begin, not from the month you applied.

This means if your SSDI started in March, your Medicare coverage begins in March of the following year, two years later. During those 24 months, you have no Medicare through SSDI, though you may be covered by Medicaid instead, depending on your state and income.

Once you reach month 25 of SSDI, Medicare Part A (hospital insurance) and Part B (medical insurance) start automatically. You do not have to explore separately or take any action. Social Security sends you a Medicare card in the mail before your coverage begins.

Key Takeaways

  • Medicare begins automatically after 24 months of SSDI payments; you do not need to explore or do anything to set up it.
  • The 24-month waiting period is a federal rule that applies to all SSDI recipients, regardless of age or diagnosis.
  • During the waiting period, you may be covered by Medicaid if your income and resources fall within your state's limits.
  • Once Medicare starts, you pay premiums for Part B and Part D (prescription drug coverage) unless your income is low enough to may have access to for cost-sharing help.
  • You can work and still receive both SSDI and Medicare through work incentive programs, even before the 24 months are up.

Why there is a 24-month wait

The 24-month waiting period exists because SSDI and Medicare are separate programs with different purposes. SSDI is an income replacement program—it pays you because you cannot work. Medicare is health insurance that anyone age 65 or older can buy, or that certain younger people receive through SSDI or End-Stage Renal Disease (ESRD).

Congress built in the waiting period to limit Medicare's costs. The logic was that people newly disabled would be covered by Medicaid (which is means-tested and state-run) during the first two years, and only after proving they could sustain long-term disability would they move to the federal Medicare program. This rule has not changed since 1972.

The waiting period applies the same way to everyone: a 25-year-old with spinal cord injury waits 24 months, just as a 55-year-old with heart disease does. Age does not shorten the wait.

What happens during the 24-month waiting period

While you wait for Medicare, your health coverage depends on your state and your income. Most states cover SSDI recipients under Medicaid during the waiting period, though the income and resource limits vary. Some states are more generous; others are stricter. A few states have waiting lists or gaps in coverage.

You should contact your state Medicaid office or use your state's online portal to find out whether you are covered and what your benefits include. Medicaid covers doctor visits, hospital stays, and prescription drugs, but the copays, deductibles, and formularies (the list of covered drugs) differ by state.

If your state does not cover you under Medicaid, or if you have income above the limit, you may be able to buy coverage through the Affordable Care Act (ACA) marketplace. SSDI income counts toward the income limit for ACA subsidies, which can lower your monthly premium significantly. You can also look into short-term health plans, though these are less comprehensive and may not cover pre-existing conditions.

Medicare Parts A and B: what you pay and what is covered

When your Medicare starts in month 25 of SSDI, you receive Part A and Part B automatically. 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 medical equipment.

Part B has a monthly premium, which is deducted from your SSDI check. In 2024, the standard premium is $164.90 per month, though it changes each year and is higher if your income exceeds certain thresholds. You also pay a yearly deductible ($240 in 2024) before Part B coverage begins, and then 20% coinsurance for most services after that.

Part A has no monthly premium if you or your spouse paid Medicare taxes for at least 10 years. Most SSDI recipients may have access to this way. Part A does have a deductible ($1,632 per hospital stay in 2024) and copays for longer stays.

Neither Part A nor Part B covers dental, vision, hearing aids, or long-term custodial care. If you need these services, you can buy a Medigap (supplemental insurance) policy or a Medicare Advantage plan, though both have their own costs and trade-offs.

Prescription drug coverage under Part D

Medicare Part D is optional prescription drug coverage. You do not receive it automatically; you must enroll during your initial enrollment period (which begins three months before your Medicare start date) or during the annual open enrollment period in the fall.

If you do not enroll in Part D when you first become Medicare-may be able to access, you pay a penalty for every month you go without it—even if you do not take any medications. The penalty is roughly 1% of the national average Part D premium per month of delay, and it is added to your premium permanently.

Part D premiums vary by plan and region. In 2024, they range from roughly $7 to $100 per month, depending on which plan you choose. You also pay a deductible (up to $545 in 2024) and copays or coinsurance for each prescription. If your income is low, you may may have access to for Extra Help, a federal program that covers most or all of your Part D costs.

How SSDI and Medicare interact with work

You can work while receiving SSDI and still keep your Medicare once it starts. This is one of the strongest work incentives in the program. Even if your earnings cause your SSDI payment to stop, your Medicare continues for at least 93 months (roughly 7.75 years) after your SSDI ends, as long as you remain disabled.

During the 24-month waiting period, you can also work under the Trial Work Period, which lets you earn up to a certain amount (in 2024, any amount) without losing SSDI. After the Trial Work Period ends, you enter the Extended may be able to access Period, during which you can work and still receive SSDI if your earnings fall below the substantial gainful activity (SGA) level—$1,550 per month in 2024 for non-blind workers.

If you work and your SSDI stops because of earnings, you do not lose Medicare. This is deliberate policy: Congress wanted to remove the fear that working would leave you uninsured. You can use this time to build work history, test your ability to work, and plan your return to the workforce without losing health coverage.

Medicaid after Medicare starts

Once Medicare begins, your Medicaid coverage may change or end, depending on your state. Some states automatically drop you from Medicaid when Medicare starts; others keep you on both programs. A few states have a special category called Medicaid Buy-In that lets you stay on Medicaid even if your income is above the normal limit, as long as you are working.

If you lose Medicaid when Medicare starts, you lose coverage for services Medicare does not pay for—like dental, vision, and long-term care. You also lose the lower copays that Medicaid often provides. Before your Medicare start date, contact your state Medicaid office to find out what will happen to your coverage and whether you may have access to for any programs that let you keep Medicaid alongside Medicare.

Frequently Asked Questions

Can I get Medicare before 24 months if I am older or have a serious condition?

No. The 24-month waiting period applies to all SSDI recipients, regardless of age or diagnosis. There are no exceptions. If you are already age 65 or older when you start SSDI, you may be able to enroll in Medicare at 65 through a different route (age-based may be able to access), but that is separate from the SSDI waiting period.

What if I do not want Medicare when it starts?

You can decline Part B (medical insurance) by contacting Social Security before your coverage begins, though Part A (hospital insurance) is automatic and harder to refuse. Declining Part B means you avoid the premium, but you also lose coverage for doctor visits and outpatient care. If you change your mind later, you may face a penalty for late enrollment.

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

Part A is free if you or your spouse paid Medicare taxes for at least 10 years. Part B has a monthly premium (deducted from your SSDI check), and Part D (prescription drugs) has a separate premium. If your income is very low, you may may have access to for programs that cover these costs.

What happens to my Medicare if I go back to work and SSDI stops?

Your Medicare continues for at least 93 months after SSDI ends, as long as you remain disabled according to Social Security's rules. After 93 months, you can keep Medicare by paying the full premium yourself, or you can switch to ACA marketplace coverage if your income qualifies for subsidies.

Can I have both Medicaid and Medicare at the same time?

Yes. Many SSDI recipients have both programs running together. Medicaid covers services Medicare does not, like dental and vision, and often pays Medicare's copays and deductibles. Whether you keep Medicaid after Medicare starts depends on your state's rules and your income.
