SSDI Includes Medicare, Not Medicaid
When you receive Social Security Disability Insurance (SSDI), you become covered by Medicare automatically after you have been on SSDI for 24 months. This is federal health insurance run by the Centers for Medicare & Medicaid Services. It is not Medicaid, which is a separate program run by states for people with low income.
The 24-month waiting period starts from the month your SSDI payments begin, not from the month you filed. If you were approved for SSDI in March, your Medicare coverage begins in March of the following year, two years later. You do not have to do anything to enroll — Social Security automatically signs you up and sends you a Medicare card in the mail.
Medicare has four parts: Part A (hospital insurance), Part B (medical insurance), Part D (prescription drug coverage), and Part C (an alternative plan). Part A and Part B are automatic. Part D requires you to choose a plan. Part C is optional and replaces Parts A and B if you select it.
Key Takeaways
- Medicare begins automatically 24 months after your SSDI payments start, and you receive it at no cost because SSDI recipients do not pay premiums for Part A or Part B.
- You must choose a prescription drug plan (Part D) during your enrollment window, or you may face a penalty if you enroll later.
- Some SSDI recipients also remain on Medicaid if they were already receiving it before SSDI approval, depending on your state's rules.
- Medicare covers hospital stays, doctor visits, and some preventive care, but you still pay copayments and deductibles for most services.
- If you return to work and your SSDI ends, your Medicare continues for at least 8.5 more years, even if your income rises above the limit.
What Medicare Part A and Part B Cover
Part A covers inpatient hospital care, skilled nursing facility care, hospice, and some home health services. If you are admitted to a hospital, Part A pays for your room, meals, and most hospital services after you meet the deductible. The deductible changes each year; in 2024 it is $1,632 for each benefit period. A benefit period starts when you enter the hospital and ends 60 days after you leave.
Part B covers doctor visits, outpatient care, medical equipment, and preventive services like screenings and vaccines. Part B has a yearly deductible (currently $240 in 2024) and then you typically pay 20 percent of the cost for most services after that. You do not pay a monthly premium for Part B as an SSDI recipient, which is different from people who enroll in Medicare at age 65.
Neither Part A nor Part B covers dental, vision, or hearing care. If you need these services, you can buy a separate Medigap policy or enroll in a Medicare Advantage plan (Part C) that may include them, though coverage varies by plan and location.
How to Choose a Prescription Drug Plan
You must enroll in Part D (prescription drug coverage) during your initial enrollment window. This window is seven months long and includes the month Medicare begins, plus three months before and three months after. If you miss this window, you can still enroll during the annual open enrollment period (October 15 to December 7 each year), but you may owe a late enrollment penalty on top of your monthly premium.
Part D plans are run by private insurance companies, and each plan has a different list of covered drugs, different copayments, and different monthly premiums. You can compare plans on Medicare.gov using their plan finder tool. Enter your current medications and the tool shows you which plans cover them and what you will pay.
Once you enroll in a Part D plan, you can change plans only during the annual open enrollment period unless you have a may have access to life event (such as moving to a different state or losing other drug coverage). If your medications or costs change during the year, you may be stuck with your current plan until the next enrollment period.
Medicaid and SSDI: When You Have Both
Some people receive both SSDI and Medicaid at the same time. This usually happens if you were already on Medicaid when you were approved for SSDI, or if you live in a state that covers working-age adults with disabilities under Medicaid. Medicaid is state-run, so the rules vary widely by location.
Medicaid covers services that Medicare does not, including dental, vision, hearing aids, and long-term care. If you have both, Medicaid often pays the copayments and deductibles that Medicare does not cover. This is called "dual coverage" and it can significantly reduce your out-of-pocket costs.
If you are unsure whether you have Medicaid, contact your state's Medicaid office or call 211 to find the local number. Your state Medicaid office can tell you whether you still may have access to and what services are covered in your state.
What Happens to Medicare if You Return to Work
If your SSDI ends because you return to work and earn too much money, your Medicare does not end when ready. You receive what is called Extended Medicare Coverage, which continues your Part A and Part B for at least 8.5 more years after your SSDI payments stop. During this time, you do not pay premiums for Part A or Part B.
After the 8.5-year extension ends, you can keep Medicare by paying a monthly premium if you are not yet 65 years old. Once you turn 65, you automatically transition to regular Medicare for people over 65, and the rules change.
This extended coverage is one reason that returning to work does not always mean losing all your benefits. You keep health insurance even if your income rises, which can make it safer to try working again.
Medicare Costs and Out-of-Pocket Expenses
As an SSDI recipient, you do not pay monthly premiums for Part A or Part B. However, you still pay deductibles and copayments when you use services. Part A has a deductible per benefit period (currently $1,632 in 2024). Part B has a yearly deductible (currently $240 in 2024) and then you pay 20 percent of approved charges for most services.
Part D (prescription drugs) has a monthly premium that varies by plan, typically ranging from $5 to $100 per month depending on which plan you choose and which drugs you need. You also pay copayments for each prescription, which can range from a few dollars for generic drugs to much more for brand-name drugs.
If your income is very low, you may be able to get help paying these costs through the Medicare Savings Program or the Low-Income Subsidy program. These are run by your state, and you can find out whether you may have access to by calling 1-800-MEDICARE or contacting your state Medicaid office.
Frequently Asked Questions
Do I have to pay for Medicare if I am on SSDI?

What if I need coverage before my 24 months of SSDI are up?
Some states cover people on SSDI under Medicaid before Medicare begins. Contact your state Medicaid office to ask whether you are covered. If not, you may be able to buy a plan through the health insurance marketplace at Healthcare.gov, and you may may have access to for a subsidy based on your income.
Can I use my Medicare outside the United States?
Medicare generally does not cover care outside the U.S., with rare exceptions for emergency care in Canada or Mexico near the border. If you travel internationally, you may want to buy a separate travel health insurance policy. Talk to your doctor before you leave about what to do if you need care abroad.
What if my doctor does not accept Medicare?
You can still see that doctor, but you will likely pay more out of pocket. Ask your doctor's office whether they accept Medicare and what you will owe. You can also search for doctors who accept Medicare on Medicare.gov or call 1-800-MEDICARE to find providers in your area.
Do I lose Medicaid when Medicare starts?
Not automatically. Some states continue Medicaid coverage alongside Medicare. Contact your state Medicaid office to confirm whether you still may have access to and what services are covered. Having both can reduce your out-of-pocket costs significantly.
