Blue Cross Blue Shield of California (Anthem Blue Cross)
Also known as: Anthem Blue Cross California, Blue Cross California, BCBS CA, Anthem CA, Blue Cross of California
Common Denial Patterns
- Medical necessity denials citing proprietary clinical guidelines that differ from DMHC standards
- Prior authorization denials for advanced imaging (MRI, CT, PET scans)
- Step therapy requirements for specialty medications, especially biologics
- Out-of-network denials in narrow network Covered California (ACA marketplace) plans
Appeal Best Practices
- 1For HMO plans, file with DMHC for Independent Medical Review — overturn rates are significantly higher than internal appeals
- 2Reference the specific Anthem CA clinical policy number in your appeal letter
- 3For behavioral health denials, cite California Mental Health Parity Act (SB 855) — broader than federal MHPAEA
- 4Include clinical guidelines (NCCN, ACR, etc.) that contradict the denial basis
Known Weaknesses

- California SB 855 (Mental Health Parity) is stronger than federal law — use it for behavioral health denials
- Covered California narrow networks create access-based appeal opportunities
- CA has among the strongest consumer protection laws for health insurance in the US
