Yes. Medicaid in Illinois covers mental health care, and it covers a wide range of it: outpatient therapy, psychiatric evaluations, medication management, inpatient psychiatric hospitalization, mobile crisis response, and intensive community-based treatment for people with serious mental illness. Most enrollees get these services through a HealthChoice Illinois managed care plan, which coordinates behavioral and medical care under one roof. The Illinois Department of Healthcare and Family Services (HFS) sets the rules.
What Mental Health Services Are Covered
Therapy, Psychiatry, and Inpatient Care
The core services are what you would expect: outpatient therapy with a licensed clinician, psychiatric evaluations, medication management, and inpatient psychiatric hospitalization when it is medically necessary. These are available under both fee-for-service Medicaid and HealthChoice Illinois managed care plans.1Illinois.gov. Medicaid Community Behavioral Health Services
Community-Based Treatment for Serious Mental Illness
For people living with serious mental illness, Illinois Medicaid funds intensive programs designed to keep people stable and out of the hospital. Community Support Team (CST) services pair a multidisciplinary team with each person and deliver treatment in real-world settings instead of a clinic. Assertive Community Treatment (ACT) follows a similar model at a higher intensity level for individuals with the most persistent conditions. Both build individualized care plans that can cover psychiatric care, therapy, and help with daily living skills.2Illinois.gov. Medicaid Community-Based Behavioral Health Services
Screenings and Assessments
Providers use the Illinois Medicaid Comprehensive Assessment of Needs and Strengths (IM+CANS) as the approved tool for integrated assessment and treatment planning. It combines a mental health assessment with an individual plan of care, so identified needs translate directly into treatment recommendations.3Illinois Department of Healthcare and Family Services. Illinois Medicaid Comprehensive Assessment of Needs and Strengths
Crisis Response
Mobile Crisis Response is available to all Medicaid enrollees, 24 hours a day, 365 days a year. Any qualified Medicaid-enrolled community mental health center or behavioral health clinic can provide these services. If you or someone you know is in a mental health crisis, call the CARES line at 1-800-345-9049 to reach mobile crisis response.4Illinois.gov. Crisis Services
Extra Coverage for Children Under EPSDT
Children and adolescents get broader coverage than adults do. The federal Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) mandate requires Illinois to provide any medically necessary service that falls within a covered Medicaid category if it will correct or improve a physical or mental condition. States cannot cap the number of medically necessary screenings and cannot require prior authorization for periodic or between-schedule screenings.5Medicaid.gov. EPSDT – A Guide for States: Coverage in the Medicaid Benefit for Children and Adolescents
In practice, that means a child under 21 whose screening reveals a mental health need is entitled to treatment even if the same service would not be covered for an adult. Covered rehabilitative services for children include community-based crisis teams, intensive outpatient services, individualized therapy delivered in non-traditional settings like schools or homes, counseling, and medication management. Illinois also operates a Screening, Assessment, and Support Services (SASS) program and a Specialized Family Support Program for youth behavioral health needs.1Illinois.gov. Medicaid Community Behavioral Health Services
Telehealth Visits
Illinois Medicaid reimburses telehealth mental health visits at the same rate as in-person appointments, as required by 89 Illinois Administrative Code 148.290(c)(3).6Illinois.gov. 2023-2024 Mental Health Parity Analysis Summary Report The 2023 Mental Health Equity Access and Prevention Act (House Bill 2847) reinforced patients’ right to choose between telehealth and in-person visits for medically necessary care.7Illinois General Assembly. 305 ILCS 5 Illinois Public Aid Code For enrollees in rural areas where the nearest behavioral health provider is hours away, that can be the difference between regular therapy and going without.
What You Pay Out of Pocket
Illinois Medicaid charges small copayments for some services. Behavioral health clinical visits carry a $3.90 copay. Brand-name prescriptions are also $3.90; generics are $2.00. Inpatient hospital stays are $3.90 per day, capped at half the department’s rate for the first day.8Illinois Department of Human Services. PM 20-03-04-a Customer Copays
Some services are exempt from copays entirely, including family planning, emergency services, and services Medicare pays for. Children and pregnant individuals are generally not subject to copays.
Who Qualifies
Adults 19 to 64
Illinois expanded Medicaid under the Affordable Care Act, so adults between 19 and 64 qualify if their modified adjusted gross income is at or below 138 percent of the Federal Poverty Level. For 2026, that works out to roughly $22,025 a year for a single-person household.9ASPE. 2026 Poverty Guidelines The 138 percent reflects a 133 percent statutory limit plus a five-percentage-point income disregard that every expansion state applies.10KFF. Medicaid Income Eligibility Limits for Adults as a Percent of the Federal Poverty Level There is no asset test for this expansion group; only income matters.
Children, Pregnant Individuals, and People Who Are Aged, Blind, or Disabled
Other categories have their own rules. Children under 19 and pregnant individuals often qualify at incomes well above 138 percent of the FPL.11Medicaid.gov. List of Medicaid Eligibility Groups For people who qualify based on age or disability, Illinois applies an asset test as well: countable resources cannot exceed $17,500, regardless of household size.12Illinois Department of Human Services. PM 07-02-01 Asset Limits
Citizenship and Immigration Status
Full Medicaid benefits generally require U.S. citizenship or lawful permanent resident status of at least five years. Children under 19 and pregnant individuals are exempt from the five-year wait. Refugees, asylees, and certain other immigrants with special status may qualify immediately.13Illinois.gov. Immigrant Eligibility for Medicaid FAQ
How to Apply
Apply through the Application for Benefits Eligibility (ABE) portal online. The same system handles SNAP, cash assistance, and Medicare Savings Programs. To apply by phone, call the ABE Customer Call Center at (800) 843-6154, or apply in person at a local Department of Human Services office.14Illinois.gov. IL Application for Benefits Eligibility Home Once approved, most enrollees are placed in a HealthChoice Illinois managed care plan.
Prior Authorization and Parity
Some mental health services and medications require prior authorization before Medicaid will pay. For fee-for-service enrollees, HFS sets those requirements. For managed care enrollees, the health plan handles authorization, but it has to follow federal parity rules.
The Mental Health Parity and Addiction Equity Act (MHPAEA) applies to Medicaid managed care plans. An MCO that covers both medical and behavioral health cannot impose stricter limits on mental health care than on comparable medical or surgical care. That includes non-quantitative limits like preauthorization rules, step therapy, and medical necessity criteria. If you ask, the MCO has to make its behavioral health medical necessity criteria available and explain the reasons for any denial.15Department of Health and Human Services. Application of MHPAEA to Medicaid MCOs, CHIP, and Alternative Benefit Plans If getting mental health care approved is harder than getting comparable medical care approved, that gap may itself be a parity violation.
Illinois has recently loosened one prior authorization requirement. Under Public Act 103-0593, effective January 1, 2025, HFS waives prior authorization for serious mental illness (SMI) medications when a patient is already stable on the medication and changes providers, changes insurance, or has a dosage or frequency adjustment. A one-time authorization may still be needed if HFS lacks the patient’s prescription history.16Illinois.gov. Provider Notice Issued 02/14/2025
If Your Plan Denies a Service
You have a right to appeal any denial, reduction, or termination of a mental health service. There are two levels.
First, file an appeal with your health plan within 60 calendar days of the date on the denial notice. The plan reviews its own decision, and you can add information or have someone represent you.17Illinois.gov. Illinois Medicaid MCO Grievance and Appeals Process
If the plan upholds the denial, request a State Fair Hearing within 120 calendar days of the plan’s appeal resolution letter. If you want to keep receiving the service while the hearing is pending, you have to request the hearing within 10 calendar days of the resolution notice. An impartial hearing officer runs the hearing, and you can bring a lawyer, relative, or friend. Appeals involving mental health services go to the Illinois Department of Human Services Bureau of Hearings. Federal rules require that the denial notice itself be written in plain language and accessible to people with limited English proficiency.18eCFR. 42 CFR 435.917 Notice of Agency Decision Concerning Eligibility, Benefits, or Services
