Medicaid Illinois: Eligibility, Application & Benefits Guide for 2026

In 2026, over 3 million Illinois residents are covered by Medicaid (also known as Medical Assistance in Illinois, with several specific programs). Under the Affordable Care Act (ACA), Illinois expanded Medicaid in 2014 to cover adults up to 138% of the Federal Poverty Level. It's administered by Illinois Department of Healthcare and Family Services (HFS) and most enrollees are served by managed care organizations (MCOs) under HealthChoice Illinois, a Medicaid benefit.

This guide outlines eligibility for illinois medicaid, the ABE Illinois process for claiming medicaid, benefits, and the process for renewing medicaid in illinois. The information is from Illinois HFS, ABE Illinois, Medicaid.gov and KFF. 

What is Medicaid Illinois?

Illinois medicaid is the state's joint federal-state health insurance program for low-income residents, including children, pregnant people, parents, adults under 65, seniors, and people with disabilities. The Illinois Department of Healthcare and Family Services administers the program, and most enrollees are covered through HealthChoice Illinois, the state's Medicaid managed care system, which contracts with multiple private insurers to deliver benefits.

Medicaid Illinois operates through several specific programs:

• FamilyCare for pregnant women, infants, and parents

• All Kids for children

• Aid to the Aged, Blind, and Disabled (AABD) for seniors and people with disabilities

• Medicaid Expansion for adults under 65 with income up to 138% FPL

• Health Benefits for Workers with Disabilities (HBWD) for working people with disabilities

For broader Medicaid context, see our Medicaid pillar guide. The Illinois rules below are state-specific examples that other states' Medicaid programs may handle differently.

Illinois Medicaid eligibility in 2026

Illinois medicaid eligibility depends on income, household size, and which program category applies to you. The federal poverty level (FPL) thresholds adjust annually each January.

Adults under 65 (Medicaid Expansion)

This is the largest eligibility group in Illinois Medicaid post-ACA-expansion. Single adults with no dependents who fall under this income threshold qualify for the same comprehensive benefits as families.

Pregnant women and infants

Higher income limits apply, typically up to 213% FPL. Pregnant women have continuous coverage through 12 months postpartum.

Children (All Kids program)

Income limits run higher than adult thresholds, with sliding-scale premiums for higher-income families through CHIP.

Seniors (65+) and People with Disabilities

Different rules apply, with both income and asset tests. For seniors needing long-term care, the Medicaid asset limit is $17,500 in 2026 (single applicant). Illinois has a "spend-down" provision for those with income above the limit.

Illinois Medicaid income limits

Most adults under 65 years old have Modified Adjusted Gross Income (MAGI) used to determine eligibility for medicaid in Illinois. MAGI contains wages, self-employment, Social Security, unemployment, alimony, and other taxable income. It doesn't include child support received, and SSI benefits.

For seniors and people with disability, the normal method of income calculation is used, which may be disregarded for medical expenses, work expenses and some other expenses. In 2026, the income limits for the Aid to the Aged, Blind, and Disabled program are approximately $1,254 per month (single) and higher for couples and larger families.

When you apply for Medicaid through ABE, the Illinois Medicaid income calculation automatically runs. The system assigns you to a program and the benefits you are eligible for.

How to apply for Medicaid in Illinois

How to apply for medicaid in illinois has three main paths in 2026:

1. ABE Illinois (Application for Benefits Eligibility)

ABE Illinois is Illinois's online portal for applying for Medicaid, SNAP, cash assistance, and other state benefits. ABE is the primary and recommended application path.

What you'll need:

• Identity verification (driver's license, state ID, passport)

• Proof of citizenship or eligible immigration status

• Income documentation (pay stubs, tax return, Social Security letter)

• Residency proof (utility bill, lease)

• Household composition (Social Security numbers for all household members)

• Information about other health coverage if applicable

ABE Illinois walks through eligibility questions, calculates which programs you qualify for, and submits the application. You can track status online and upload requested documents through the portal.

2. Healthcare.gov

If you start on Healthcare.gov when shopping for marketplace coverage, the system will identify Medicaid eligibility and forward your information to Illinois HFS for processing. This is common during ACA open enrollment.

3. By phone or in person

Illinois HFS accepts applications by phone (1-800-843-6154) or in person at your local Department of Human Services office. This option is particularly useful for people without internet access or for complex applications involving long-term care or disability determinations.

Standard processing takes 30 days for non-disability applications and up to 90 days for disability-based or long-term care applications. Presumptive eligibility provides immediate temporary coverage in some emergency situations.

Medicaid Illinois benefits

Illinois Medicaid benefits are comprehensive and follow federal mandatory benefit requirements with significant state-added benefits:

• Hospital and physician services

• Prescription drugs through Illinois Medicaid pharmacy network

• Mental health and substance use treatment

• Family planning (no copay)

• Pregnancy and maternity care

• Pediatric services (full EPSDT coverage for children)

• Vision care (eye exams covered, glasses covered with limits)

• Dental care (limited adult dental for non-pregnant adults; full dental for children and pregnant women)

• Long-term care (nursing facility, home and community-based services for those who qualify)

• Transportation to medical appointments

Illinois has expanded its adult dental Medicaid coverage in recent years, though it remains less comprehensive than coverage for children. For dental specifics, see our Medicaid dental for adults state-by-state guide.

For specialty access, see our eye doctors that accept Medicaid and dermatologists that accept Medicaid guides.

ABE Illinois Medicaid renewal

Illinois medicaid renewal happens annually for most enrollees. Illinois HFS sends renewal notifications about 60 days before your renewal date. The renewal can typically be completed online through ABE Illinois, by mail, or by phone.

To prepare for renewal:

• Update your contact information with HFS so renewal notices reach you

• Have current income documentation ready

• Track changes in household composition (new children, marriages, divorces, deaths)

• Respond promptly to renewal requests because non-response leads to coverage termination

After the COVID-19 public health emergency ended in 2023, Illinois (along with all states) resumed regular eligibility redeterminations. Many enrollees lost coverage during this "unwinding" period because of paperwork issues rather than actual ineligibility. Make sure ABE has your current address and phone number to avoid this.

HealthChoice Illinois: how managed care works

HealthChoice Illinois is the state's mandatory Medicaid managed care program. Most enrollees must select a managed care organization (MCO) within 30 days of becoming eligible. If you don't select, you'll be auto-assigned. Major MCOs in Illinois include Blue Cross Blue Shield, CountyCare (in Cook County), Meridian Health Plan, Molina Healthcare, and others.

The MCO handles your day-to-day care, including provider networks, prior authorizations, member services, and care coordination. You can switch MCOs once during your first year of enrollment, then once a year during open enrollment.
