The most common California Medicaid denials seen in Los Angeles 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 Los Angeles visit is decisive for clean first-pass payment. Across Los Angeles's 233 organizations, even a few percentage points of MCO-routing error compounds into material rework.
