Where to apply for Illinois Medicaid

You apply for Illinois Medicaid through the Department of Human Services (DHS), which runs the program statewide. The easiest way to start is through the ISBE Online Services portal at abe.illinois.gov, where you can submit your application from home without visiting an office. You can also apply by mail, phone, or in person at your local DHS office — the DHS website has a location finder if you want to visit one.

If you are applying for the first time or reapplying after a gap, you will need to create an account on the ISBE portal. The system walks you through the questions and tells you right away if you appear to meet the income and resource limits. Paper applications are available by calling 1-877-597-1900, though the online route is faster because DHS can process it without waiting for mail delivery.

You do not need to choose between online and mail — many people start online to see if they may have access to, then mail in supporting documents. The portal tells you exactly which documents to send and where to mail them.

Key Takeaways

  • Apply through the ISBE Online Services portal at abe.illinois.gov, by phone at 1-877-597-1900, or at your local DHS office.
  • You will need proof of income, residency, citizenship or immigration status, and Social Security numbers for everyone in your household.
  • DHS typically makes a decision within 30 days of receiving all required documents, though some cases take longer if information is missing.
  • If you are denied, you can request a hearing to challenge the decision, and you have the right to see the documents DHS used to make its choice.
  • Your coverage can start as early as the first day of the month you applied, even if DHS has not finished reviewing your case yet.

Documents you need to gather before applying

DHS requires proof of several things, and having these documents ready before you start your application speeds up the process. You will need proof of income for the past 30 days — this can be recent pay stubs, a letter from your employer, bank statements showing deposits, or tax returns if you are self-employed. If you receive benefits like Social Security or unemployment, bring the award letter or a recent statement showing the amount.

You also need proof of residency in Illinois, which can be a utility bill, lease, mortgage statement, or government mail with your current address. Bring proof of citizenship or immigration status — a birth certificate, passport, or green card works. For immigration status, DHS accepts certain visa types and work permits; the ISBE portal has a full list if you are unsure whether yours qualifies.

Finally, you will need Social Security numbers for everyone in your household who is applying. If someone does not have a number yet, you can still apply, but DHS will ask you to get one before coverage starts. Bring photo ID if you are applying in person, though it is not required for online or mail applications.

Income and resource limits for Illinois Medicaid

Illinois Medicaid has different income limits depending on which category you fall into — parent or caregiver, child, pregnant person, elderly, or disabled. The limits change each year, and they are higher than many people expect. For example, a parent caring for a child can earn significantly more than the federal poverty line and still be covered. The exact number depends on your household size and which group you belong to.

DHS also looks at resources, which means money in the bank, vehicles, and property you own. Most people under 65 can have up to $2,000 in countable resources; people 65 and older can have up to $3,000. Your home and one vehicle do not count toward this limit. If you are over the resource limit, you may still be covered under a different program or after spending down some assets.

The ISBE portal shows you the current income limits for your household size when you start your application. If you are close to the limit, apply anyway — DHS counts income in a specific way, and what you earn may not be counted the same way you think it is.

What happens after you submit your application

Once DHS receives your application, they send you a notice telling you they got it and what documents they still need. If you applied online, check your ISBE account regularly for messages — DHS uses the portal to ask for missing information rather than mailing letters. If you applied by mail or phone, watch for mail from DHS.

DHS typically makes a decision within 30 days of receiving all the documents they need. If documents are missing, the clock pauses until you send them. Some cases take longer if DHS needs to verify your income with your employer or if your situation is complicated. You can call 1-877-597-1900 to check on your case status, though having your application number ready makes the call faster.

If you are approved, your coverage can start as early as the first day of the month you applied, even if DHS is still reviewing your paperwork. You will receive a card in the mail within one to two weeks. If you are denied, the notice will explain why and tell you how to request a hearing to challenge the decision.

Reapplying if your coverage ended

Illinois Medicaid coverage lasts 12 months, and DHS sends you a renewal notice about 30 days before it expires. If you miss the renewal deadline, your coverage stops, but you can reapply at any time. The process is the same as your first application — use the ISBE portal, call, or visit an office.

If your coverage ended because you did not renew, you may have a gap where you are not covered. Some people are covered retroactively back to the date their old coverage ended if they reapply quickly and still meet the rules. Call DHS to ask whether your situation qualifies for retroactive coverage.

If your income or household changed during your coverage period, you can report the change to DHS before your renewal date. This can help you avoid losing coverage or being overpaid if your situation changed.

What to do if you are denied

If DHS denies your application, the notice will say why — usually because your income is too high, you do not meet the residency requirement, or you did not provide proof of citizenship. Read the notice carefully, because it explains exactly what DHS found and what you can do next.

You have the right to request a fair hearing to challenge the decision. You must ask for the hearing within 30 days of the denial notice. At the hearing, you can present new information, explain your situation, and ask questions about how DHS made its decision. You also have the right to see all the documents DHS used to decide your case.

If your income is the issue, you may be able to reapply after your circumstances change. If you were denied because of immigration status, you might be covered under a different program — call DHS to ask what other options exist.

Using your Illinois Medicaid card

Once you receive your card, you can use it at any doctor, hospital, or pharmacy that takes Illinois Medicaid. You do not need to choose a primary care doctor unless you are in a managed care plan — some people get traditional Medicaid where they can see any provider, while others are automatically enrolled in a managed care plan that requires them to pick a doctor. Your approval notice will tell you which type you have.

Keep your card with you when you go to medical appointments. If you lose it, call the number on your renewal notice or contact DHS to request a replacement. Your coverage is active even if you are waiting for a new card to arrive in the mail.

Frequently Asked Questions

Can I apply for Medicaid if I am undocumented?

Illinois Medicaid is open to certain immigrants, including those with work permits, visas, and green cards. Undocumented immigrants are not covered under regular Medicaid, but Illinois has a separate program called Medicaid for Immigrants that covers emergency services and some preventive care. Call 1-877-597-1900 to ask about this program.

How long does it take to get approved?

DHS usually decides within 30 days of receiving all your documents. If documents are missing, the timeline pauses until you send them. Some cases take longer if DHS needs to verify information with your employer or if your situation is complex. You can check your status anytime through the ISBE portal or by calling DHS.

What if my income changes after I am approved?

Report the change to DHS as soon as possible — you can do this through the ISBE portal or by calling 1-877-597-1900. If your income goes up, you might lose coverage or have to pay back some benefits. If it goes down, you might be covered under a different category with better benefits. DHS will recalculate your coverage based on the new information.

Can I apply if I have a job but no pay stubs yet?

Yes. Bring a letter from your employer stating your job title, start date, and expected pay. DHS will use this to estimate your income. Once you receive pay stubs, send them to DHS to update your file. If your actual income is lower than the estimate, DHS may owe you money back.

What if I am approved but think DHS made a mistake?

You can request a fair hearing within 30 days of any decision you disagree with — not just denials. At the hearing, you can present new information and ask questions about how DHS decided your case. You also have the right to see all documents DHS used. Call 1-877-597-1900 to request a hearing.
