Who Runs SSDI and Medicaid—and Why They're Separate

SSDI and Medicaid are run by different federal agencies with different rules

No, SSDI and Medicaid are not run by the same company or agency. SSDI (Social Security Disability Insurance) is administered by the Social Security Administration, a federal agency that handles all Social Security programs. Medicaid is administered by the Centers for Medicare & Medicaid Services (CMS), which is part of the Department of Health and Human Services. They operate under different laws, have different funding sources, and make decisions independently—even though they often affect the same person.

The confusion is understandable because the two programs are tightly linked in practice. If you receive SSDI, you automatically become may be able to access for Medicare after 24 months. Many people on SSDI also receive Medicaid, especially in the early years before Medicare kicks in. But the agencies do not share a single decision-making process, and approval for one program does not automatically mean approval for the other.

Key Takeaways

The Social Security Administration runs SSDI; the Centers for Medicare & Medicaid Services runs Medicaid—they are separate federal agencies with separate budgets and rules.
SSDI is a federal program with the same rules in every state; Medicaid is jointly funded by federal and state money, so rules vary by state.
You can be approved for SSDI but denied Medicaid, or vice versa, because each program has its own income and resource limits.
After 24 months on SSDI, you move to Medicare for health coverage, but Medicaid may continue depending on your state and income.

How the Social Security Administration runs SSDI

The Social Security Administration (SSA) is a standalone federal agency that processes SSDI claims, makes disability decisions, and pays monthly benefits. When you file for SSDI, you work with the SSA's local field office or online portal. The SSA has its own medical consultants and vocational experts who review your case. They decide whether you meet the definition of disability under federal law, and that decision is final within the SSA—no state can override it or add extra requirements.

SSDI funding comes from payroll taxes (the Social Security trust fund), not from general tax revenue. Because it is a federal program, the rules are identical nationwide. Your monthly benefit amount depends on your work history and earnings record, not on where you live. The SSA also handles work incentives, overpayment recovery, and appeals—all within the same agency.

How CMS and states run Medicaid together

Medicaid is jointly run by the federal government (through CMS) and each state. CMS sets the broad rules and provides federal funding, but each state designs its own Medicaid program within those rules. This means may be able to access, covered services, and payment rates differ by state. Some states are more generous; others are more restrictive. A person might be on Medicaid in one state and ineligible in another, even with the same income and disability status.

Because Medicaid is state-administered, you explore through your state's Medicaid office, not through a federal agency. Your state determines whether you meet its income and resource limits, whether your disability is recognized under state rules, and what services are covered. CMS oversees the states to may support they follow federal law, but the day-to-day decisions are made locally.

Why SSDI approval does not automatically mean Medicaid approval

Being approved for SSDI proves you meet the federal definition of disability, but it does not automatically prove you meet your state's Medicaid rules. Each program has its own income limits and resource limits (the amount of money and assets you can have). SSDI's income limit is higher than many states' Medicaid limits. You could receive an SSDI benefit that is too high to also receive Medicaid in your state—though most states have workarounds for this situation.

Additionally, some states require a separate Medicaid disability information even if you are already on SSDI. They may use different medical standards or ask for updated medical evidence. In other states, SSDI approval streamlines the Medicaid process but does not eliminate it entirely. You still have to file a Medicaid process and provide proof of your SSDI award.

The 24-month Medicare transition and what happens to Medicaid

After you have been on SSDI for 24 months, you automatically become may be able to access for Medicare Part A (hospital insurance) and Part B (medical insurance). This is a federal rule that applies everywhere. At that point, Medicare becomes your primary health coverage, and you pay Medicare premiums from your SSDI benefit.

What happens to Medicaid depends on your state and income. In some states, you lose Medicaid when Medicare starts because your SSDI benefit is now counted as income. In other states, Medicaid continues as a secondary payer to help cover costs Medicare does not pay. A few states have special programs (like Medicaid Buy-In programs) that let you keep Medicaid even after Medicare begins. You need to check with your state's Medicaid office to know what applies to you.

Why the two agencies do not share a single decision

SSDI and Medicaid are separate programs created by different laws passed at different times. SSDI was created in 1956 as part of Social Security; Medicaid was created in 1965 as part of Medicare. They have different purposes: SSDI replaces lost income; Medicaid pays for medical care. Because they serve different goals, Congress gave them different rules and put them under different agencies.

The two agencies do communicate. When you are approved for SSDI, the SSA can send your award notice to your state's Medicaid office to speed up the Medicaid process. But they do not share a single database or decision-making process. Each agency independently verifies your information, reviews your medical evidence, and makes its own information. This separation can feel frustrating, but it also means that a mistake by one agency does not automatically affect the other.

What you need to do to get both programs

If you want both SSDI and Medicaid, you must file separate applications. Start with SSDI through the Social Security Administration—either online at ssa.gov, by phone at 1-800-772-1213, or in person at your local field office. The SSDI process typically takes three to six months for an initial decision.

While you wait for SSDI, file for Medicaid with your state's Medicaid office. Do not wait for the SSDI decision. Your state may approve you based on your disability, income, and resources alone. Once you receive your SSDI award letter, send a copy to your state's Medicaid office; they may use it to confirm your may be able to access or adjust your benefits. Keep both agencies informed of any changes in your income, resources, or living situation, because each program tracks these differently.

Frequently Asked Questions

If I am denied SSDI, can I still get Medicaid?

Yes. Medicaid has its own disability standard, which is sometimes different from SSDI's. You can be denied SSDI and still be approved for Medicaid, or vice versa. File for both programs independently and let each agency make its own decision based on its own rules.

Do I have to report changes to both SSDI and Medicaid separately?

Yes. Changes in income, resources, living situation, or medical condition must be reported to both the Social Security Administration and your state's Medicaid office. They do not share real-time information, so reporting to one does not automatically update the other. Failure to report can result in overpayments or loss of benefits.

Why does my SSDI benefit count as income for Medicaid but not for other programs?

Each program has its own rules about what counts as income and what the income limit is. Medicaid's income limit is often lower than SSDI's benefit amount, which is why some people lose Medicaid when they are approved for SSDI. Some states have special rules or programs to help people in this situation; ask your state's Medicaid office about options.

Can I appeal a Medicaid denial if I was approved for SSDI?

Yes, but the SSDI approval does not may provide a Medicaid appeal will succeed. You can appeal the Medicaid denial through your state's process, which usually involves a hearing before a state official. Bring your SSDI award letter as evidence of your disability, but be prepared to show you also meet your state's specific income and resource rules.

What if my state's Medicaid office says I am ineligible because my SSDI benefit is too high?

Ask about Medicaid Buy-In programs, Medicaid Spend-Down options, or other state programs designed for people on SSDI. Some states let you set aside income or resources to reduce your countable income. Your state's Medicaid office or a benefits counselor can explain what options exist in your state.
