Practice requirements for ABA providers in Illinois

As of 2026-10-21, per the cited Illinois rule (Section 140.465), Medicaid ABS payment may go to enrolled Behavioral Health Clinics (BHCs) or to independently enrolled ABS clinicians. Independent clinicians may bill their own services and supervised technician services within an employment, contractual or similar relationship. BHC requirements are set out in Section 140.499; the cited HFS notices do not establish a universal ABA facility license. Clinic certification details were not researched.

Providers must enroll via the IMPACT system. For fee-for-service (FFS) customers, prior authorization applies to BATP services exceeding six hours (24 units) per 180 days and to all BAI services (HFS notice of Jan 19, 2021). The BATP is to be updated once every 180 days. The current ABS fee schedule retains conditional authorization for assessment ("Yes if >6 hours"). Effective April 15, 2025, all ABS prior authorization requests for FFS customers must be submitted via the OMI Clinical Review Platform (CRP). Managed-care providers must follow their MCO's own authorization procedures, which may differ from the FFS requirements above.

89 Ill. Adm. Code 140.465(b)(3) requires clinical supervision of each ABS Technician by an ABS Clinician equal to at least 5 percent of the technician's time delivering ABS services per month, including at least two face-to-face, real-time contacts per month. An RBT must be supervised by an LCP, BCBA, BCBA-D, or BCaBA. A non-RBT developmental-intervention technician must be supervised by an LCP or by an LCSW, LCPC, LMFT, licensed OT, or licensed SLP with Department-approved developmental-intervention training. A BCaBA may practice as an ABS Clinician only under supervision of an LCP, BCBA, or BCBA-D; the rule sets no percentage for that supervision. An independently enrolled ABS Clinician may bill only for services the clinician personally provides or that a technician with an employment, contractual, or similar relationship provides under that clinician's supervision (140.465(a)(2)). The 05/14/2026 fee schedule requires prior authorization for BAI codes, including 97153 (daily maximum 32 quarter-hour units, Level 2 $13.00, daily maximum $416), and for BATP codes 97151, 97152, and 0362T only if more than 6 hours. Team services billed with HT require at least 1 BCBA plus 2 RBTs, or 1 developmental clinician plus 2 developmental technicians. BATP must be completed before BAI and reviewed at least every 180 days (140.465(c)(1)(A)).
