Insurance & Medicaid Coverage in Illinois

Illinois has expanded Medicaid under the ACA, significantly broadening access to addiction treatment for low-income adults earning up to 138% of the federal poverty level (~$20,783/year for an individual). Covered services typically include medical detox, inpatient/residential rehab, outpatient counseling, and medication-assisted treatment (MAT). In addition to Medicaid, most private insurance plans — including Blue Cross Blue Shield, Aetna, Cigna, UnitedHealthcare, and Humana — are required by the Mental Health Parity Act to cover substance use disorder treatment at parity with medical care.
