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

  1. 1For HMO plans, an Independent Medical Review through DMHC is available if the internal appeal does not resolve the denial; ask for it
  2. 2Reference the specific Anthem CA clinical policy number in your appeal
  3. 3For behavioral health denials, cite California Mental Health Parity Act (SB 855) — broader than federal MHPAEA
  4. 4Include clinical guidelines (NCCN, ACR, etc.) that contradict the denial basis

Points to Check

  • DMHC Independent Medical Review is independent of Anthem and has strong consumer protections
  • California SB 855 (Mental Health Parity) is stronger than federal law — use it for behavioral health denials
  • If no in-network provider is reasonably available, document it to support an access-based appeal
  • California adds state review rights on top of federal law — DMHC for HMO plans, CDI for PPO plans; check which one regulates your plan
