What Medicare Coverage You Get When SSDI Is Approved

You Get Medicare Automatically After 24 Months on SSDI

Once the Social Security Administration approves you for SSDI, you do not have to do anything else to get Medicare. After you have been receiving SSDI payments for 24 consecutive months, Medicare enrollment happens automatically. You will receive your Medicare card in the mail without having to submit a separate form or contact anyone.

The 24-month waiting period starts from the month you first become may have access to to SSDI benefits, not from the month you explore. If you were approved retroactively — meaning Social Security determined your disability began in an earlier month — the 24 months count backward from that earlier date. This means some people become Medicare-may be able to access before they receive their first SSDI check.

You do not pay a premium for Medicare Part A (hospital insurance) because of your SSDI status. Part A covers hospital stays, skilled nursing facility care, hospice, and home health services. This is different from how Medicare works for people age 65 and older, many of whom pay a monthly premium for Part A.

Key Takeaways

Medicare enrollment is automatic 24 months after your SSDI approval date; you receive your card by mail with no action required on your part.
You get Medicare Part A (hospital insurance) at no monthly cost because you are on SSDI, unlike most people who turn 65.
Medicare Part B (doctor visits and outpatient care) has a monthly premium that is deducted from your SSDI check unless you choose to decline it.
The 24-month clock starts from your SSDI entitlement date, which may be earlier than your approval date if you were approved retroactively.
You can enroll in Part D (prescription drug coverage) or a Medicare Advantage plan during your initial enrollment period or during the annual open enrollment window.

Medicare Part B and What It Costs

Medicare Part B covers doctor visits, outpatient surgery, diagnostic tests, and other services outside a hospital setting. Unlike Part A, Part B requires a monthly premium. For 2024, the standard Part B premium is $164.90 per month, though this amount changes each year. The premium is automatically deducted from your SSDI payment, so you do not have to pay it separately.

You are enrolled in Part B automatically when you become Medicare-may be able to access through SSDI. If you do not want Part B coverage, you can decline it, but you should understand the consequences before you do. If you turn down Part B and later want to enroll, you may face a permanent penalty on your premium unless you have a may have access to reason for the delay.

Some people with very low income may be able to get help paying Part B premiums through Medicaid or the Medicare Savings Program, which is run by your state. These programs are separate from SSDI and have their own income limits. You can contact your state Medicaid office or call 1-800-MEDICARE to learn whether you may be able to get help with costs.

Part D and Prescription Drug Coverage

Part D is optional prescription drug coverage. You are not automatically enrolled in Part D when you become Medicare-may be able to access through SSDI. Instead, you have an initial enrollment period of 63 days centered around the month you become Medicare-may be able to access — that is, 30 days before, the month itself, and 30 days after.

If you do not enroll in Part D during this window and you do not have other creditable drug coverage (such as coverage through a current or former employer), you will pay a penalty if you enroll later. The penalty is 1 percent of the national average Part D premium for each month you were without coverage. Like the Part B penalty, this penalty is permanent.

You can enroll in Part D during the annual open enrollment period, which runs from October 15 to December 7 each year. Coverage changes take effect on January 1. You can also enroll if you experience a may have access to life event, such as loss of other drug coverage or a move to a different state.

Medicare Advantage Plans and Other Coverage Options

Medicare Advantage (Part C) is an alternative to Original Medicare (Part A and Part B). With Medicare Advantage, a private insurance company provides your Part A and Part B coverage, usually with a lower or zero premium. However, Medicare Advantage plans often have higher out-of-pocket costs when you use care, and they usually require you to use doctors and hospitals within their network.

You can enroll in a Medicare Advantage plan during your initial enrollment period when you first become Medicare-may be able to access, or during the annual open enrollment period from October 15 to December 7. If you enroll in Medicare Advantage, you are still covered by Part A and Part B, but through the private plan instead of Original Medicare.

Some Medicare Advantage plans include Part D prescription drug coverage, while others do not. If your plan does not include Part D and you want drug coverage, you cannot enroll in a standalone Part D plan while you are in Medicare Advantage. You would need to switch back to Original Medicare first.

What Happens Before Your 24 Months Are Up

Between the time you are approved for SSDI and the time you become Medicare-may be able to access, you may still need health insurance. Some people continue coverage through a spouse's employer plan, Medicaid, or the Affordable Care Act marketplace. Others go without coverage during this period.

If you have Medicaid when you become Medicare-may be able to access, Medicaid continues to exist alongside Medicare. In this situation, Medicaid is called "dual may be able to access" coverage and can help pay Medicare premiums and cost-sharing. The rules for dual may be able to access coverage vary by state, so contact your state Medicaid office to understand what will happen to your coverage once Medicare starts.

Some states have programs that help people with disabilities pay for health insurance before they reach Medicare age. These programs are not automatic, so you would need to contact your state Medicaid office or your state's disability services agency to learn what is available where you live.

Your Medicare Card and Account Setup

When you become Medicare-may be able to access, Social Security mails your Medicare card to the address on file. The card shows your Medicare number, which is usually your Social Security number followed by a letter. Keep this card in a safe place and bring it to all doctor visits and hospital stays.

You can create a Medicare account online at Medicare.gov to view your coverage, check claims, and read your card if it is lost. You will need your Medicare number and an email address to set up the account. Having an online account makes it easier to track your coverage and resolve billing issues.

If you move or change your address, update it with Social Security as soon as possible so your Medicare card reaches you. You can update your address online at ssa.gov, by phone at 1-800-772-1213, or in person at your local Social Security office.

Frequently Asked Questions

What if I am already on Medicare when I get approved for SSDI?

If you are already receiving Medicare (for example, because you are age 65 or older), your coverage does not change when you are approved for SSDI. You continue with the same Medicare plan. However, if you were paying a Part B premium before, you will no longer pay it once you have been on SSDI for 24 months, because SSDI recipients do not pay Part A or Part B premiums.

Do I have to take Medicare Part B when I become may be able to access?

No, you can decline Part B. However, if you decline and later want to enroll, you may face a permanent 10 percent penalty on your premium for each year you were without coverage. The only exceptions are if you have other creditable coverage (such as through an employer) or if you have a may have access to reason for the delay.

Can I switch from Original Medicare to Medicare Advantage after I enroll?

Yes. You can switch during the annual open enrollment period from October 15 to December 7, or if you have a may have access to life event such as a move or loss of coverage. Changes take effect on January 1 of the following year, or the first of the month following a may have access to event.

What if I cannot afford my Medicare premiums?

Your state may have programs to help pay Part B and Part D premiums if your income is low enough. Contact your state Medicaid office or call 1-800-MEDICARE to ask about the Medicare Savings Program or other state information programs. You can also ask your doctor's office or local hospital about financial information programs they offer.

Will my SSDI payment change when I become Medicare-may be able to access?

Your SSDI payment amount does not change when you become Medicare-may be able to access. However, your Part B premium will be deducted from your check starting the month your Medicare coverage begins. If you decline Part B, your full SSDI payment goes to you without this deduction.
