Illinois Medicaid and Evanston routing.
HealthChoice Illinois covers bh billing for eligible Illinois beneficiaries, delivering most of that benefit through managed care organizations with a remaining fee-for-service population. The most common Illinois Medicaid denials seen in Evanston are prior authorization missing or expired, plan-of-record mismatch (patient assigned to different MCO), medical necessity documentation insufficient, timely filing exceeded, and managed care vs FFS routing errors. Because each MCO credentials providers separately and enrollment runs 60-120 days from clean application, confirming plan assignment and credentialing status before the first Evanston visit is decisive for clean first-pass payment. Across Evanston's 447 organizations, even a few percentage points of MCO-routing error compounds into material rework.
