Choosing care in Illinois

Compare providers on the care they deliver, not on a ranking. Look at the levels of care offered, whether medications for opioid use disorder are available, the populations served, payment and insurance options, and the current licensing status of each program.

Where you can, call each option in Illinois and confirm services, licensing, cost, insurance, and current openings in writing. No ratings, inspections, or quality scores are published for these SAMHSA listings, so direct confirmation is the surest check.
