Summary
Illinois providers must follow new behavioral health utilization management requirements effective Jan 1, 2026, with no prior authorization needed for initial periods (72 hours for inpatient, 48 hours for intensive outpatient, 2 business days for other outpatient). Notification requirements and timelines differ between commercial and Medicaid members.
Action Required
By Jan 1, 2026: Billing team must update prior authorization workflows to exclude first 72 hours for inpatient behavioral health, first 48 hours for intensive outpatient/partial hospitalization, and first 2 business days for outpatient behavioral health services. Train staff on notification requirements: 48 hours for commercial inpatient admissions, 24 hours for Medicaid services. Update billing system to track first treatment dates for outpatient services to determine coverage periods. Failure to provide first treatment date will trigger medical record requests.
