Where to start your Illinois Medicaid application

You apply for Medicaid in Illinois through the Department of Human Services (DHS), which runs the program statewide. The fastest way to start is online through the ISBE (Illinois State Benefits portal) at benefits.illinois.gov, where you can submit your application without leaving home. You can also apply in person at your local DHS office, by mail, or by phone at 1-877-204-1012.

The online portal is usually the quickest option because it processes faster and you get confirmation immediately. If you do not have internet access or prefer to speak with someone, your local DHS office can walk you through the application over the phone or in person. Many offices have extended hours and some offer same-day appointments.

Before you start, gather documents that show your income, household size, citizenship or immigration status, and Social Security numbers for everyone in your household. You do not need all of these on day one — DHS will tell you what is missing — but having them ready speeds up the process.

What documents you need to have ready

Illinois Medicaid requires proof of several things, and what you need depends partly on your situation. For income, bring recent pay stubs (usually the last 30 days), tax returns, or a letter from your employer. If you receive unemployment, Social Security, or other benefits, bring the award letter or a recent statement showing the amount.

You will also need proof of citizenship or immigration status. A birth certificate, passport, or naturalization papers work for citizenship. If you are not a U.S. citizen, bring your immigration documents — a green card, work permit, or visa. DHS can also verify citizenship electronically in some cases, so ask if they can do that instead of collecting the document yourself.

For household size, list everyone living with you and their relationship to you. You will need their Social Security numbers and dates of birth. If someone in your household is a minor, you may need to show guardianship or custody documents.

If you own property, a car, or have savings, DHS may ask for proof of those assets. Keep bank statements, property deeds, and vehicle registration handy. Illinois has asset limits for some Medicaid programs, though the limits are high enough that most people do not hit them.

How long the application process takes

DHS has 30 days from the date they receive your complete application to make a decision. "Complete" means they have everything they asked for — if documents are missing, the clock does not start until you send them. In practice, many applications are decided within two to three weeks if nothing is missing.

If DHS needs more information, they will contact you by mail or phone. You usually have 10 days to respond. If you miss the deadline, your application may be denied, but you can reapply or request a hearing to explain why you could not respond in time.

Once you are approved, coverage typically starts on the first day of the month after DHS receives your complete application. If you apply on the 15th of January and are approved, your coverage would start February 1st. In some cases — such as if you are pregnant or a child — coverage can start sooner.

What happens after you submit your application

After you submit online or by mail, DHS will send you a notice in the mail within a few days confirming they received it. This notice will have a case number and instructions for checking the status of your application. You can also log into benefits.illinois.gov to see updates.

If DHS needs documents from you, they will send a letter listing what they need and when you need to send it. You can mail documents, upload them through the online portal, or bring them to your local DHS office. Uploading through the portal is fastest because it creates a record immediately.

When DHS makes a decision, they will mail you a notice. If you are approved, the notice will tell you your coverage start date and how to use your Medicaid card. If you are denied, the notice will explain why and tell you how to request a hearing to challenge the decision.

If your application is denied

A denial usually means DHS found that you do not meet the income limit, citizenship requirement, or another rule for the program you applied for. The denial notice will explain the specific reason. Read it carefully, because it also tells you how to request a hearing.

You have 30 days from the date on the denial notice to request a hearing. You can do this by mail, phone, or online through benefits.illinois.gov. At the hearing, you can present documents or witnesses to show why you believe the decision was wrong. A hearing officer will review your case and make a new decision.

If you were denied because of income, you may still be able to get coverage through a different Medicaid program with a higher income limit. For example, if you do not may have access to for regular Medicaid, you might may have access to for Medicaid for the Elderly, Blind, and Disabled (MEBD) or a program for pregnant women or children. DHS can tell you which programs you might be may be able to access for.

Reapplying if your circumstances change

If your income, household size, or other circumstances change after you are denied, you can reapply. You do not have to wait any amount of time — you can submit a new application the same day. Changes that might make you newly may be able to access include a job loss, a reduction in hours, a new child, or the death of a household member.

When you reapply, mention in your application that you previously applied and were denied. Include the date of the denial if you remember it. This helps DHS understand your situation and can speed up the review.

Getting help with your application

If you get stuck or do not understand what DHS is asking for, several organizations in Illinois offer free help. Legal Aid Chicago, Equip for Equality, and local community action agencies can walk you through the application or help you prepare documents. Many of these organizations can also represent you at a hearing if your application is denied.

You can also call DHS directly at 1-877-204-1012. The line is usually busy during peak hours (morning and early afternoon), so calling in late afternoon or the next day often gets you through faster. Have your case number ready if you have already applied.

Some local DHS offices have application assistants on staff who can help you fill out forms or upload documents. Call your local office to ask if this service is available and whether you need an appointment.

Frequently Asked Questions

Can I apply for Medicaid if I am not a U.S. citizen?

Yes, but your immigration status matters. Lawful permanent residents (green card holders), refugees, asylees, and certain other immigration statuses can get Medicaid. Undocumented immigrants cannot get regular Medicaid, but Illinois offers a separate program called Medicaid for Immigrants that covers emergency services and some preventive care. Bring your immigration documents when you apply, and DHS will tell you which program you may have access to for.

What if my income is too high for Medicaid?

Income limits vary by program and household size. If your income is slightly above the limit, you might still may have access to for a different Medicaid program or for a tax credit to help you buy insurance through the marketplace. DHS can tell you what other options exist. You can also reapply if your income drops later.

How do I check the status of my application?

Log into benefits.illinois.gov with your username and password to see real-time updates. You can also call 1-877-204-1012 and give DHS your case number. The online portal is usually faster because you do not have to wait on hold.

What if I need coverage to start before the first of the month?

In some situations, coverage can start sooner. Pregnant women, children, and people with urgent medical needs may be able to get coverage in the same month they apply. Call DHS or ask when you submit your application if you have a time-sensitive medical need.

Can I apply for my child if I do not may have access to?
