You Get Medicare, Not Medicaid, Once You've Been on SSDI for Two Years
When you receive Social Security Disability Insurance (SSDI), you do not automatically get health insurance the moment your benefits start. Instead, you become may be able to access for Medicare — the federal health insurance program for people over 65 and certain younger people with disabilities — after you have been receiving SSDI payments for 24 consecutive months. This two-year waiting period is a fixed rule; it does not change based on your income or medical condition.
Medicare is different from Medicaid. Medicaid is a state-run program for people with low income, and you may still may have access to for it while waiting for Medicare to begin, depending on your state and your income. But the insurance that comes with SSDI itself is Medicare, and it covers hospital care, doctor visits, prescription drugs, and other medical services once the 24-month clock runs out.
Key Takeaways
- Medicare begins automatically after 24 months of receiving SSDI payments; you do not need to explore separately for it.
- Medicare Part A covers hospital stays and skilled nursing care, while Part B covers doctor visits and outpatient services, and you pay a monthly premium for Part B.
- You can add Part D (prescription drug coverage) or a Part C plan (Medicare Advantage) to lower your out-of-pocket costs, though each has different rules and networks.
- While waiting for Medicare to start, you may may have access to for Medicaid in your state, which has different income limits and covers services Medicare does not.
- Once Medicare begins, you keep it for life as long as you remain on SSDI, even if your income rises above the usual Medicare income limits.
How the Two-Year Waiting Period Works
The 24 months begins the month your SSDI payments start, not the month you applied. If the Social Security Administration approves your claim in June and your first check arrives in July, your Medicare may be able to access date is July of the second year following — roughly 24 months later. You do not have to do anything during this waiting period; Social Security tracks it automatically.
During those 24 months, you should explore whether you may have access to for Medicaid in your state. Medicaid rules vary widely — some states cover people with disabilities regardless of income, while others have strict income caps. Contact your state Medicaid office or call 211 to find out what you may be able to access while you wait. Some people may have access to for both Medicaid and Medicare at the same time, which can reduce what you pay out of pocket.
What Medicare Part A and Part B Cover
Part A covers inpatient hospital care, skilled nursing facility care after a hospital stay, hospice care, and some home health services. Part A has no monthly premium — it is included with your SSDI. You do pay a deductible when you enter the hospital, and you share costs for longer stays, but Part A is the foundation of your coverage.
Part B covers doctor visits, outpatient services, lab tests, imaging, and preventive care. Part B does have a monthly premium, which is deducted from your SSDI check. In 2024, the standard Part B premium is $164.90 per month, though the amount changes each year and may be higher if your income is above a certain threshold. You also pay a deductible and a percentage of the cost for each service.
Both Part A and Part B have gaps in coverage. They do not cover dental care, vision care, hearing aids, or long-term custodial care in a nursing home. This is why many people on Medicare add supplemental coverage or choose a different plan structure.
Adding Part D for Prescription Drugs and Part C as an Alternative
Part D is prescription drug coverage, and you can add it when Medicare starts or during the annual enrollment period in the fall. Part D is sold by private insurance companies approved by Medicare, and the plans vary in which drugs they cover and what you pay. If you do not sign up for Part D when you first become may be able to access and you go without it for more than 63 days, you may pay a penalty for the rest of your life. If you take medications regularly, signing up is usually worth the cost.
Part C, also called Medicare Advantage, is an alternative to Original Medicare (Parts A and B). With Part C, a private insurance company provides your Part A and Part B coverage, usually with lower out-of-pocket costs and sometimes dental or vision benefits included. The trade-off is that you must use doctors and hospitals in the plan's network, and you may need approval before certain services. Part C plans change every year, so you should review your options during the annual enrollment period each fall.
You cannot have both Original Medicare and Part C at the same time — you choose one or the other. If you have Part C and want to switch back to Original Medicare, you can do so during the annual enrollment period, though you should add Part D at the same time if you do not already have it.
What Happens to Your Medicare if Your SSDI Ends
Once you have been on SSDI for at least five years and you turn 65, your SSDI automatically converts to retirement benefits under Social Security. Your Medicare continues without interruption. If your SSDI ends for another reason — such as work activity that exceeds the substantial gainful activity limit — you may be able to keep Medicare for a limited time. This is called Extended Medicare Coverage, and it lasts up to eight and a half years after your SSDI ends, though you must pay the full premium yourself.
If you lose SSDI and do not may have access to for Extended Medicare Coverage, you will lose Medicare unless you are 65 or older. This is why it is important to understand the rules about work and SSDI before you return to full-time employment.
Medicaid While You Wait for Medicare and Beyond
Medicaid is a separate program run by each state, and it covers people with low income and limited resources. While you are waiting for Medicare to begin, Medicaid may cover services that SSDI alone does not — such as dental care, vision care, and personal care information. Medicaid also has no monthly premium and often lower out-of-pocket costs than Medicare.
In some states, you automatically may have access to for Medicaid when you are approved for SSDI. In others, you must explore separately and meet income and resource limits. A few states have expanded Medicaid to cover more people with disabilities. Call your state Medicaid office or 211 to learn what is available where you live. If you may have access to for both Medicaid and Medicare, Medicaid can pay some of your Medicare premiums and cost-sharing, which is called "dual may be able to access" status.
Frequently Asked Questions
Do I have to pay for Medicare when it starts?
Part A has no monthly premium. Part B does — in 2024 it is $164.90 per month, deducted from your SSDI check. If you add Part D or choose Part C, those have their own premiums. You also pay deductibles and cost-sharing when you use services.
What if I cannot afford the Part B premium?
If your income is low, you may may have access to for a Medicare Savings Program in your state, which helps pay your Part B premium and other costs. Contact your state Medicaid office or call 211 to learn whether you may have access to. Some people also may have access to for both Medicaid and Medicare, which can lower their total costs.
Can I choose not to take Medicare when it starts?
You can decline Part B, but Part A is automatic. If you decline Part B and later want it, you can sign up during the annual enrollment period, though you may pay a penalty. It is usually better to enroll even if you do not think you will use it right away.
Does Medicare cover dental, vision, or hearing aids?
Original Medicare does not cover routine dental, vision, or hearing aids. Some Part C (Medicare Advantage) plans include dental or vision benefits, but coverage varies by plan. Medicaid in your state may cover these services, so check what your state offers.
What if I go back to work while on SSDI?
SSDI has work incentives that let you earn money and keep some or all of your benefits for a limited time. Your Medicare continues during this period. If your earnings eventually cause your SSDI to end, you may keep Medicare for up to eight and a half years under Extended Medicare Coverage, though you must pay the full premium yourself.
