The most common Delaware Medicaid denials seen in Wilmington 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 Wilmington visit is decisive for clean first-pass payment. Across Wilmington's 13 organizations, even a few percentage points of MCO-routing error compounds into material rework.
