California Medicaid and Pasadena routing.
Medi-Cal covers pediatric billing for eligible California beneficiaries, delivering most of that benefit through managed care organizations with a remaining fee-for-service population. The most common California Medicaid denials seen in Pasadena 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 Pasadena visit is decisive for clean first-pass payment. Across Pasadena's 23 organizations, even a few percentage points of MCO-routing error compounds into material rework.
