Illinois Medicaid serves many different groups of people. As of 2024, the program covers adults earning up to 138% of the federal poverty level, which means a single adult earning approximately $1,810 per month or a family of three earning around $3,824 per month may be covered. The program also serves children, seniors aged 65 and older, people with disabilities, and pregnant women and new mothers.
The program has expanded significantly in recent years. In 2014, Illinois expanded Medicaid to include more working-age adults. This expansion meant that thousands of additional Illinois residents gained access to coverage they did not have before. Today, more than 2.8 million Illinois residents rely on Medicaid for their health insurance.
Illinois Medicaid covers both inpatient and outpatient services. Inpatient services mean staying overnight in a hospital. Outpatient services include visits to doctors' offices, urgent care clinics, and emergency rooms where you do not stay overnight. The program also covers prescription drugs through its pharmacy benefit program. Many medications are covered at a lower cost or at no cost to members.
Mental health and substance use treatment services are covered benefits. This includes counseling, therapy, psychiatric care, and rehabilitation programs. Dental services for adults include cleanings, fillings, and extractions. Vision care covers eye exams and glasses or contact lenses.
Takeaway: Illinois Medicaid is a state health insurance program that covers hospital care, doctor visits, medications, and other medical services for people with lower incomes. Understanding what the program covers helps you know what services you may receive if you participate.
Illinois Medicaid has income and asset limits that determine whether someone may receive coverage. Income limits change each year because they are tied to the federal poverty level, which adjusts annually. For 2024, the monthly income limit for a single adult is approximately $1,810. For a family of two, the limit is around $2,449 per month. A family of four faces a limit of approximately $3,727 per month.

These income limits apply to gross income, which means income before taxes are taken out. Gross income includes wages from employment, self-employment income, Social Security benefits, retirement income, unemployment benefits, and child support. Some types of income do not count toward the limit. For example, the first $20 of unearned income per month and the first $65 of earned income per month are not counted.
Assets are also considered, though the asset limits are quite high. Currently, the asset limit is $2,000 for individuals and $3,000 for couples. Assets include savings accounts, checking accounts, stocks, bonds, and other property. However, certain assets do not count, such as your primary home, one vehicle, household goods, and personal items.
Pregnant women have different income rules than other adults. Pregnant women and women up to 60 days after delivery may be covered at income levels up to 214% of the federal poverty level, which is significantly higher than the regular adult limit. This means a pregnant woman can earn more money and still get coverage.
Children have their own income limits. Children under age 19 may be covered at income levels up to 218% of the federal poverty level. This is much higher than adult limits. A family of four with income up to approximately $5,614 per month may have their children covered, even if the parents do not meet adult limits.
Seniors and people with disabilities often have access to Medicaid based on their receipt of Supplemental Security Income (SSI), rather than just income limits. If someone receives SSI, they typically automatically meet Medicaid financial limits.
Takeaway: Medicaid in Illinois has specific income and asset limits that vary by family size and relationship to the program (adult, child, pregnant woman, senior, or person with disability). Knowing these limits helps you understand where you stand financially in relation to the program.
When you start the process of joining Illinois Medicaid, you will need to gather certain documents to verify your information. Having these documents ready before you begin makes the process smoother. The main categories of documents relate to identity, residency, income, and citizenship or immigration status.

For proof of identity, you may use a driver's license, state ID card, passport, or birth certificate. You should bring the original document or a certified copy. If you do not have any of these, a work ID, school ID, or letter from a shelter or social service agency may work. The goal is to prove who you are.
To show you live in Illinois, bring a recent utility bill, lease agreement, mortgage statement, or mail from a government agency. The document should show your name and current Illinois address and should be dated within the last 60 days. A landlord's letter can also work if you do not have official documents.
Income verification requires different documents depending on your income source. If you work as an employee, bring recent pay stubs from the last 30 days or a letter from your employer showing your wages and hours. Self-employed people should provide tax returns or business records. If you receive Social Security, SSI, unemployment, or retirement income, bring the most recent award letter or benefit statement from the agency providing the payment.
If you care for children, you may need to show proof of the children's ages. Birth certificates work best. If children live with you but you are not the parent, you may need custody papers or a letter from the parent allowing the child to live with you.
For citizenship or immigration status, U.S. citizens should bring a birth certificate, passport, or naturalization papers. Legal immigrants need to provide their Permanent Resident Card (green card) or other immigration documents showing their status. Some qualified non-citizens may be covered, so it is important to provide accurate immigration information.
If you are applying as a parent or caretaker of a child, you will need similar documents for yourself plus documents proving your relationship to the child. Married couples need to show marriage certificates.
Takeaway: Gathering documents related to identity, residency, income, and citizenship before you file for Illinois Medicaid makes the process more efficient. Keep copies of important documents in a safe place for reference.
