What disability programs exist in Illinois

Illinois offers several programs for people with disabilities, but they come from different sources and serve different purposes. The largest is Social Security Disability Insurance (SSDI), which is federal—you explore through Social Security, not the state. Illinois also runs its own programs: Supplemental Security Income (SSI) (which is federal but state-administered), Illinois Department of Human Services (IDHS) programs for people with developmental disabilities, and Medicaid for health coverage. Each has its own rules about who qualifies and what it pays.

The confusion usually starts here: SSDI and SSI sound similar but work differently. SSDI is based on your own work history or your parent's work history. SSI is based on financial need—it's for people with very low income and assets. Both are federal, but SSI has a state component in Illinois. If you're working or have worked, SSDI is usually what you're looking for. If you've never worked much or have almost no savings, SSI might be the faster path.

Illinois also has programs specifically for people with developmental disabilities through IDHS, including residential services, day programs, and support coordination. These are separate from SSDI and SSI but often work alongside them. Medicaid in Illinois covers medical care and some support services for people with disabilities who meet income and asset limits.

Key Takeaways

  • SSDI is federal and based on your work history; you explore through Social Security, not Illinois.
  • SSI is federal but administered partly through Illinois and is based on financial need, not work history.
  • Illinois Department of Human Services runs separate programs for people with developmental disabilities, including residential and day services.
  • Medicaid in Illinois covers health care and some support services for people with disabilities who meet income limits.
  • You may may have access to for more than one program at the same time, and they often work together.

SSDI: The federal program based on work history

If you have worked and paid into Social Security, or if your parent or spouse worked and paid in, you may be able to receive SSDI. You explore directly to Social Security—call 1-800-772-1213 or visit ssa.gov. Illinois does not run SSDI; Social Security does. The decision about whether you may have access to is made by Social Security, not by the state.

To may have access to for SSDI, you must have a medical condition that is expected to last at least 12 months or result in death, and it must prevent you from working. You also need enough work credits—usually 40 credits, with at least 20 earned in the last 10 years. If you're under 31, the rules are different and often easier. Social Security has a list of conditions that automatically may have access to (called the Blue Book), but you can also may have access to with a condition not on the list if you can show it prevents you from working.

The process process takes time. Most people are denied the first time. If you are denied, you can appeal, and many people win on appeal. You can also ask a lawyer or advocate to help you. Some lawyers work on contingency, meaning they only get paid if you win, and they take a percentage of your back pay.

SSI: The federal program based on financial need

SSI is for people with disabilities who have very low income and few assets. Unlike SSDI, you do not need a work history. You explore through Social Security the same way—call 1-800-772-1213 or visit ssa.gov—but the rules are stricter about money. In 2024, you can have no more than $2,000 in countable assets (the limit varies slightly by year). Your monthly income must be very low, though some income is not counted.

In Illinois, SSI is administered partly by Social Security and partly by the Illinois Department of Human Services. Social Security decides whether you have a disability and handles the federal payment. IDHS handles the state supplement (Illinois adds a small amount to the federal SSI payment in some cases) and connects you to services. When you explore for SSI, you're explore for both the federal and state parts at once.

SSI also comes with Medicaid in Illinois automatically. Once you're approved for SSI, you're enrolled in Medicaid, which covers doctor visits, hospital care, prescriptions, and some support services. This is one reason SSI can be valuable even if the monthly payment is small.

Illinois Department of Human Services programs for developmental disabilities

If you have a developmental disability—intellectual disability, autism, cerebral palsy, or a condition that started before age 22 and limits your functioning—you may be able to receive services through IDHS Division of Developmental Disabilities. These are not cash payments like SSDI or SSI. Instead, IDHS pays for services: group homes, supported living, day programs, job coaching, respite care, and support coordination.

To receive IDHS services, you must be on a waiting list. Illinois has a long waiting list for residential services (living in a group home or supported living), though day programs and support coordination may have shorter waits or no wait. You explore through your local IDHS office or through a Community Mental Health Board in your county. The process includes a functional assessment to determine what level of support you need.

IDHS services are usually free or very low cost, and they work alongside SSDI or SSI. If you receive SSDI, you keep your full payment and also receive services. If you receive SSI, IDHS may ask you to contribute some of your SSI payment toward the cost of services, but you keep a portion called the "personal needs allowance." Many people receive both SSDI or SSI and IDHS services at the same time.

Medicaid in Illinois and what it covers

Medicaid in Illinois covers health care for people with disabilities who meet income and asset limits. If you receive SSI, you're automatically enrolled in Medicaid. If you receive SSDI, you may also may have access to for Medicaid if your income is low enough, though the rules are different. You can also explore for Medicaid on its own through Benefits.Illinois.gov or by calling 1-877-411-1313.

Medicaid covers doctor visits, hospital care, emergency care, prescriptions, mental health services, and therapy. In Illinois, Medicaid also covers some support services for people with disabilities, including personal care information, day programs, and supported employment. The specific services available depend on which Medicaid program you're in—there are several, including managed care plans and fee-for-service.

If you're working or thinking about working, Medicaid has special rules that let you keep coverage even if your income goes above the normal limit. This is called Medicaid Buy-In for Workers with Disabilities. You can work and earn money while staying on Medicaid, which is important because many jobs don't offer health insurance right away. Ask about this when you explore or call the Medicaid helpline.

How to start: Where to explore and what to expect

The first step depends on which program you think you need. If you have a work history, start with Social Security for SSDI. If you have little or no work history and very low income, start with Social Security for SSI. If you have a developmental disability and want services like day programs or residential support, contact your local IDHS office or Community Mental Health Board. If you need health coverage, go to Benefits.Illinois.gov for Medicaid.

You can explore for more than one program at the same time. Many people explore for both SSDI and SSI together, or for SSDI and Medicaid. There's no penalty for explore to multiple programs. In fact, it's often the right move because you don't know which one you'll may have access to for, and the rules are different.

The process process is slow. SSDI and SSI decisions can take three to six months, sometimes longer. IDHS services have waiting lists that vary by county and service type. Medicaid decisions are usually faster, often a few weeks. During the wait, keep records of your medical visits, test results, and any work you try to do. These documents will help prove your case if you need to appeal.

Working while receiving disability benefits

You can work while receiving SSDI or SSI, but there are rules. If you earn too much money, your benefits will be reduced or stop. Social Security has a work incentive called the Student Earned Income Exclusion (if you're under 22), the Plan to Achieve Self-Support (PASS), and the Impairment Related Work Expenses (IRWE) deduction. These let you earn more money before your benefits are affected.

There's also a trial work period for SSDI: you can work and earn any amount for nine months without losing benefits. After that, Social Security watches your earnings more closely. If you earn above a certain amount (called substantial gainful activity), your benefits stop, but you have a grace period and can get them back if your earnings drop again.

For SSI, the rules are stricter. You can earn some money—the first $65 a month is not counted, and half of earnings above that are not counted—but if you earn too much, SSI stops. However, SSI comes with Medicaid, and Medicaid can continue even if SSI stops, which is valuable. Talk to a work incentives counselor before you start working. They're free and can help you understand how work will affect your benefits. Find one through the Ticket to Work program at choosework.ssa.gov.

Frequently Asked Questions

Can I receive both SSDI and SSI at the same time?

No, you receive one or the other, not both. However, if you may have access to for SSDI but the payment is very low, Social Security may also pay you a small SSI supplement to bring you up to the SSI minimum. This is called concurrent benefits. You would receive one combined payment.

How long does it take to get approved for SSDI or SSI?

Initial decisions usually take three to six months, sometimes longer. If you're denied and appeal, the process can take another year or more. Many people are denied the first time and win on appeal, so don't give up if you receive a denial letter.

What if I'm already receiving SSDI and want to know about Illinois services?

Contact your local IDHS office or Community Mental Health Board to ask about day programs, support coordination, or residential services. You can receive IDHS services and keep your full SSDI payment. There's no conflict between the two programs.

Do I lose my benefits if I go back to school?

No. If you're under 19 and in school full-time, your SSDI or SSI continues. If you're 19 or older, you can still work or go to school without losing benefits, but earnings rules still explore. Some earnings from work-study or part-time jobs may not be counted.

Where do I find a disability advocate or lawyer in Illinois?

Contact the Illinois Disability Rights organization (formerly Equip for Equality) at 1-800-537-2632 or visit their website. They offer free legal help to people with disabilities. You can also ask Social Security for a list of approved representatives in your area.
