Medicare is included with SSDI, but only after you have been receiving disability payments for 24 months

When you are approved for Social Security Disability Insurance (SSDI), you do not automatically receive Medicare. Instead, Medicare coverage begins in your 25th month of receiving SSDI payments. This means there is a waiting period between when your SSDI payments start and when your health insurance through Medicare begins.

The 24-month waiting period is set by federal law and applies to nearly all SSDI recipients, regardless of age or the reason for your disability. The only exception is if you have End-Stage Renal Disease (ESRD) — permanent kidney failure requiring dialysis or transplant — in which case Medicare can begin when ready, even before your first SSDI payment arrives.

Once your Medicare coverage starts, it is permanent as long as you continue to receive SSDI. You do not have to reapply or renew it each year. If your SSDI payments stop for any reason, your Medicare coverage stops as well, though there are limited circumstances where you can keep it.

Key Takeaways

  • Medicare coverage begins in month 25 of receiving SSDI, not at the start of your payments.
  • The 24-month waiting period is automatic and applies to almost all SSDI recipients, with ESRD as the only common exception.
  • Medicare Part A (hospital insurance) and Part B (medical insurance) are both included at no cost to you during the waiting period and after.
  • If your SSDI payments stop, your Medicare coverage stops, but you may be able to continue it by paying the premium yourself.
  • You can enroll in Medicare Advantage or a prescription drug plan during your waiting period, even though Part A and B do not start until month 25.

What Medicare coverage you receive and when it starts

Your Medicare coverage includes Part A (hospital insurance) and Part B (medical insurance covering doctor visits and outpatient care). Both parts are provided at no monthly premium cost to you because you are receiving SSDI. This is different from Medicare for people age 65 and older, many of whom pay a monthly premium for Part B.

The coverage begins on the first day of your 25th month receiving SSDI. For example, if your SSDI payments begin in January 2024, your Medicare coverage starts on January 1, 2025. Social Security will send you a Medicare card in the mail before your coverage begins, usually a few weeks in advance.

You are automatically enrolled in both Part A and Part B. You do not have to sign up or take any action. However, you can decline Part B if you choose, though this is rare and usually not recommended because you would lose coverage for doctor visits and other outpatient services.

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

During the 24 months before Medicare starts, you need health insurance from another source. Many SSDI recipients use Medicaid, which is a joint federal and state program that covers low-income individuals. Medicaid rules vary by state, but most states cover SSDI recipients automatically or make them very straightforward to enroll in.

To learn about you may have access to for Medicaid in your state, contact your state Medicaid office or call 211 (a free referral service). You can also explore online through your state's benefits portal. Some states have already enrolled you in Medicaid when you were approved for SSDI, so check your mail for a Medicaid card.

If Medicaid is not available to you or you do not may have access to, you may be able to purchase coverage through the Affordable Care Act (ACA) marketplace at healthcare.gov. Because your SSDI income is typically low, you may receive a subsidy that reduces your monthly premium significantly.

Even though your Medicare Part A and B do not start until month 25, you can enroll in Medicare Advantage plans or prescription drug plans (Part D) during your waiting period if you want additional coverage. This is optional, but some people do this to may support they have prescription coverage from day one.

What happens to Medicare if your SSDI payments stop

If your SSDI payments end — whether because your medical condition improved, you returned to work, or for another reason — your Medicare coverage also stops. The timing depends on why your payments stopped. If you return to work and your payments end because your earnings are too high, Medicare typically continues for a grace period, but this varies.

Once your Medicare coverage ends, you can continue it by paying the full monthly premium yourself. As of 2024, the Part B premium ranges from roughly $165 to $560 per month depending on your income, but this amount changes each year. You would also pay a premium for Part D (prescription drug coverage) if you want it.

If you cannot afford to pay the premium, you may may have access to for Medicare Savings Programs, which are state-run programs that help pay your Medicare premiums and cost-sharing. Contact your state Medicaid office to learn whether you may have access to.

How to prepare before your Medicare coverage begins

A few months before your 25th month of SSDI, Social Security will mail you a Medicare card. Check the card for accuracy — make sure your name, date of birth, and Social Security number are correct. If there are errors, call Social Security at 1-800-772-1213 to correct them before your coverage begins.

Before your Medicare starts, choose a primary care doctor who accepts Medicare. Not all doctors do, so call ahead to confirm. Having a primary care doctor in place means you can start using your Medicare coverage when ready when it begins, rather than scrambling to find one later.

If you are currently using Medicaid or ACA coverage, ask your current doctor whether they accept Medicare. If they do, you can often continue seeing them without interruption. If they do not, you will need to find a new doctor once Medicare begins.

Review your current medications and make sure you understand how they will be covered under Medicare Part D. If you do not enroll in a Part D plan during your waiting period, you can enroll when your Medicare starts, but waiting may result in a penalty if you go without prescription coverage.

Special situations: ESRD and other exceptions

If you have End-Stage Renal Disease requiring dialysis or a kidney transplant, Medicare begins when ready upon approval for SSDI, not after 24 months. You will receive your Medicare card within a few weeks of being approved for SSDI. This exception exists because ESRD requires when ready, ongoing medical care that cannot wait.

If you are age 65 or older when you are approved for SSDI, you may already be enrolled in Medicare through the regular age-65 program. In this case, your SSDI approval does not change your Medicare coverage — you keep the same coverage you already had. However, if you were not yet enrolled in Medicare at age 65, your SSDI approval will trigger enrollment at that time.

If you are a widow, widower, or adult child receiving benefits on a deceased worker's Social Security record (not SSDI), different rules explore. Contact Social Security directly to understand how Medicare works with your specific situation.

Frequently Asked Questions

Can I get Medicare before 24 months if I have a serious health condition?

No. The 24-month waiting period applies to all SSDI recipients except those with End-Stage Renal Disease. There is no exception for other serious conditions, no matter how urgent your medical needs are. During the waiting period, use Medicaid or ACA coverage for your health care.

Do I have to pay anything for Medicare once it starts?

No. Part A and Part B are provided at no monthly premium cost because you are receiving SSDI. You may have small copayments or coinsurance when you use services, but there is no monthly premium. If you enroll in Medicare Advantage or Part D, those may have premiums depending on the plan.

What if I miss the important date to enroll in a Medicare Advantage or Part D plan?

If you do not enroll in Part D during your waiting period or when Medicare starts, you may pay a penalty for each month you go without coverage. The penalty is added to your Part D premium permanently. You can enroll during the annual enrollment period (October 15 to December 7) or if you have a may have access to life event.

Can I keep Medicare if I go back to work and my SSDI stops?

It depends on why your SSDI stopped. If you return to work and your earnings exceed the limit, you may have a grace period where Medicare continues. After that, you can keep Medicare by paying the monthly premium yourself. Contact Social Security to understand your specific situation before you return to work.

Do I need to do anything to enroll in Medicare, or is it automatic?

Enrollment is automatic. You do not have to sign up or submit any paperwork. Social Security will send you a Medicare card in the mail before your coverage begins. The only action you might take is to decline Part B if you choose, though this is not recommended for most people.
