Illinois Medicaid Autism Coverage
Illinois Medicaid covers ABA therapy for children under 21 through the Adaptive Behavior Services benefit. For long-term community services, families must join PUNS (the statewide waiting list) — selection for the Children's Support or AWDD waiver is based on urgency of need, not time on the list, and can take years.
