What’s available in Marissa
In-home usually starts sooner than the drive is worth

Coverage itself is set statewide, not locally. Illinois Medicaid covers medically necessary ABA for eligible children anywhere in Illinois, and Illinois’s autism insurance law reaches private plans issued in the state. Your address changes which providers can reach you — it doesn’t change whether you’re covered.
