ABA therapy in Chicago: what to know before you start

In Chicago you will find ABA delivered through hospital-affiliated clinics, large multi-site companies, and smaller independent practices, in centers, homes and sometimes schools. That breadth is an advantage, but quality and philosophy vary widely, so the vetting is on you. Illinois's insurance mandate (since 2011) means most state-regulated private plans cover ABA generally through age 21, and Medicaid covers medically necessary ABA for children under 21 through EPSDT — which is why demand and supply are both high here.

Funding for longer-term developmental disability supports runs through a separate Illinois system worth knowing about: PUNS, the statewide waitlist for DD Waiver services. ABA itself is usually billed to insurance or Medicaid rather than through PUNS, but because PUNS placement is driven by how long someone has been waiting, registering early on PUNS is widely recommended even while you pursue insurance-funded ABA. You enroll through a local Independent Service Coordination agency, and Illinois Life Span (https://www.illinoislifespan.org) has clear guidance.
