Who provides public treatment in Chicago
The Illinois Helpline for Opioids and Other Substances at 1-833-234-6343 (or text HELP to 833234) is free and confidential and helps residents find substance use care, including publicly funded programs for people without insurance.
You can also search findtreatment.gov from ZIP code 60601 and filter by level of care, medication, and payment option.
Levels of care to expect
Care is matched to the person, usually after an assessment. Options near Chicago range from medically supervised detox and residential treatment to intensive outpatient programs, regular outpatient counseling, and medication for opioid or alcohol use disorder. Alcohol and benzodiazepine withdrawal can be dangerous, so ask about medical withdrawal management before stopping heavy use.
Paying for treatment
Illinois expanded Medicaid, so more adults qualify than in non-expansion states. Illinois Medicaid, administered by the Department of Healthcare and Family Services and largely delivered through HealthChoice Illinois managed care plans, covers medically necessary substance use disorder treatment, including withdrawal management, residential and outpatient care, and methadone, buprenorphine, and naltrexone.
If you have private insurance, federal parity rules require your plan to cover substance use treatment on terms comparable to medical care; ask about in-network programs and prior authorization. If you are uninsured, ask the Illinois Helpline for Opioids and Other Substances about publicly funded programs or help applying for Illinois Medicaid.
