Idaho Medicaid and Lewiston routing.
Idaho Medicaid covers behavioral health billing for eligible Idaho beneficiaries, delivering most of that benefit through managed care organizations with a remaining fee-for-service population. The most common Idaho Medicaid denials seen in Lewiston 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 Lewiston visit is decisive for clean first-pass payment. Across Lewiston's 82 organizations, even a few percentage points of MCO-routing error compounds into material rework.
