You become may be able to access for Medicare automatically after you have been on SSDI for 24 months

If you receive Social Security Disability Insurance (SSDI), you do not need to do anything special to get Medicare. The Social Security Administration automatically enrolls you in Medicare Part A (hospital insurance) and Part B (medical insurance) once you have been receiving SSDI payments for 24 consecutive months. This happens whether you are 65 or younger — age does not matter for SSDI recipients.

The 24-month waiting period starts from the month you first received an SSDI payment, not from the month you applied. If you were approved retroactively and received back payments, those months still count toward your 24 months. Social Security will send you a Medicare card in the mail about three months before your coverage begins.

You will be enrolled in both Part A and Part B unless you actively decline Part B before your coverage starts. Most people keep both parts because Part A covers hospital stays and Part B covers doctor visits and outpatient care. If you turn down Part B when you first become may be able to access, you can sign up later, but you may pay a higher premium for the rest of your life.

Key Takeaways

  • Medicare enrollment happens automatically 24 months after your first SSDI payment, with no action required on your part.
  • You receive both Part A (hospital) and Part B (doctor and outpatient) coverage unless you decline Part B in writing before your coverage date.
  • Your SSDI payment and your Medicare premium are separate — Medicare Part B premiums are deducted from your SSDI check each month.
  • You can choose a Medicare Advantage plan or stay with Original Medicare, and you can change your choice each year during the annual enrollment period.
  • If you work and your earnings are high enough to end your SSDI, your Medicare coverage continues for at least 93 more months even after payments stop.

What happens to your SSDI payment when Medicare starts

When your Medicare coverage begins, your SSDI payment does not change. However, your Medicare Part B premium is deducted from your SSDI check each month. For 2024, the standard Part B premium is $164.90 per month, though the amount changes yearly and may be higher if your income was above a certain level in prior years.

You will see the deduction listed on your SSDI payment stub. If you also have Part D coverage (prescription drugs) or a Medigap supplemental plan, those premiums are paid separately — they do not come out of your SSDI check. Part A has no monthly premium for most people who have paid into Social Security long enough, which includes most SSDI recipients.

If your SSDI payment is very small and the Part B premium would reduce it below a certain threshold, Social Security may delay the deduction or handle it differently. Contact Social Security directly if your payment seems incorrect after Medicare starts.

Original Medicare versus Medicare Advantage when you are on SSDI

When you turn 65 or after your 24 months on SSDI ends, you can choose between two ways to receive your Medicare benefits: Original Medicare (Part A and Part B) or a Medicare Advantage plan. Original Medicare is run by the federal government and works the same way for everyone. Medicare Advantage plans are run by private insurance companies and often include prescription drug coverage (Part D) and extra benefits like dental or vision, but they have networks and may require referrals.

If you do nothing, you will be enrolled in Original Medicare by default. To switch to a Medicare Advantage plan, you must actively choose one during the annual enrollment period (October 15 to December 7 each year) or when you first become may be able to access for Medicare. You can switch back to Original Medicare the following year if you change your mind.

Many people on SSDI choose Medicare Advantage because the plans often have lower or zero monthly premiums and include drug coverage. However, Original Medicare gives you more freedom to see any doctor who accepts Medicare. Compare the plans available in your area each year — the options and costs change.

Prescription drug coverage and other add-ons

Medicare Part D (prescription drug coverage) is optional but strongly recommended if you take any medications. You can get Part D through a standalone plan if you have Original Medicare, or it is usually included in a Medicare Advantage plan. If you do not sign up for Part D when you first become may be able to access for Medicare, you will pay a penalty for each month you go without it — the penalty is added to your premium permanently.

Medigap (supplemental insurance) is another optional add-on that works only with Original Medicare. Medigap helps pay the costs that Original Medicare does not cover, such as copayments and coinsurance. It is sold by private insurance companies and has a monthly premium paid separately from your SSDI check. You have the best rates and widest choice of Medigap plans if you sign up within six months of starting Part B.

If you have a Medicare Advantage plan, you cannot also have Medigap. Medicare Advantage plans are designed to cover most of what Medigap would, though the coverage works differently because of the network and referral requirements.

What happens to your Medicare if your SSDI ends

If you return to work and your earnings become high enough to end your SSDI payments, your Medicare coverage does not stop when ready. You have what is called Extended Medicare Coverage, which means you can keep your Medicare for at least 93 more months (about 7.75 years) after your SSDI payments end. During this time, you continue to pay the Part B premium, which is deducted from your paycheck or paid directly to Medicare.

This extended coverage period is one of the biggest work incentives in the SSDI program. It means you can test your ability to work without losing health insurance. If you go back to work and your SSDI ends, Social Security will send you a notice explaining your extended coverage period and how to pay your premiums.

After your extended coverage ends, you can continue Medicare if you pay the full premium yourself, or you can switch to your employer's health plan if one is available. You will not have another chance to sign up for Part D at the lower initial enrollment rate, so do not drop it during your extended coverage period unless you have other drug coverage.

How to contact Medicare and make changes to your coverage

Once you have Medicare, you can call Medicare directly at 1-800-MEDICARE (1-800-633-4227) to ask questions, make changes to your plan, or report problems. You can also visit Medicare.gov to compare plans, view your coverage details, and manage your account online. Medicare has representatives available 24 hours a day, 7 days a week.

If you need help understanding your options, you can contact your State Health Insurance information Program (SHIP), which offers free counseling about Medicare. Find your state's SHIP by calling 1-800-MEDICARE or visiting shiptalk.org. SHIP counselors can explain the differences between plans in your area and help you understand your costs.

Changes to your Medicare coverage can only be made during specific times: when you first become may be able to access, during the annual enrollment period (October 15 to December 7), or if you have a may have access to life event such as moving to a new state or losing other health coverage. Outside these windows, you are locked into your current plan.

Income-related premiums and extra help programs

If your income is above a certain level, you will pay a higher Medicare Part B premium. Social Security uses your income from two years ago to calculate this, so if your income was high in 2022, you might pay more for Medicare in 2024. The higher amount is called an Income-Related Monthly Adjustment Amount (IRMAA). You can appeal an IRMAA if your income dropped due to a life event such as retirement or a job loss.

If your income is low, you may be able to get help paying your Medicare premiums and cost-sharing through programs like the Medicare Savings Program or the Low-Income Subsidy (also called Extra Help). These programs are run by your state, and you can find out whether you may have access to by calling 1-800-MEDICARE or visiting your state Medicaid office. The income limits vary by state.

Frequently Asked Questions

Do I have to accept Medicare when it is offered to me after 24 months on SSDI?

You are automatically enrolled in Part A and Part B. You can decline Part B before your coverage starts by contacting Social Security in writing, but this is rarely recommended because you will pay a penalty if you sign up later. Part A has no monthly premium for most SSDI recipients, so there is no reason to turn it down.

What if I am already on Medicare when I start receiving SSDI?

If you are 65 or older and already have Medicare when your SSDI begins, your coverage continues without interruption. Your SSDI payment will still be reduced by the Part B premium each month. You do not need to do anything — Social Security coordinates automatically with Medicare.

Can I use Medicaid and Medicare at the same time?

Yes. If your income and resources are low enough to may have access to for Medicaid, you can have both Medicare and Medicaid. Medicaid covers costs that Medicare does not, and in some states, Medicaid pays your Medicare premiums. Contact your state Medicaid office to see if you may have access to.

What if I disagree with my IRMAA premium amount?

You can appeal an IRMAA if your current income is significantly lower than the income Social Security used to calculate it. You must file an appeal with Social Security within 60 days of receiving your notice. Life events such as job loss, retirement, or death of a spouse are common reasons for a successful appeal.

Does my spouse get Medicare automatically if I am on SSDI?

No. Your spouse has their own Medicare may be able to access based on their own age or disability status. If your spouse is under 65 and not disabled, they do not become may be able to access for Medicare just because you are on SSDI. They would need to may have access to on their own through age, disability, or end-stage renal disease.
