Blue Shield of California Denial Appeal Guide

Blue Shield of California Appeal Process

Like all California HMO/POS plans, Blue Shield is regulated by DMHC, giving you access to independent medical review.

How to Appeal

1. File an internal grievance with Blue Shield within 180 days
2. File DMHC IMR — you can file simultaneously for medical necessity denials
3. Blue Shield must respond within 30 days (72 hours for urgent)
4. If denied internally — DMHC IMR is your strongest option

Common Denial Reasons

• Prior authorization not obtained
• Medical necessity not met per clinical criteria
• Out-of-network provider used
• Treatment considered experimental
• Benefit exclusion in plan documents

California Consumer Protections

• DMHC IMR with ~60% patient success rate
• Timely access requirements (must see specialist within 15 business days)
• Continuity of care protections (can keep your doctor during plan transitions)
• Mental health parity enforcement
• Network adequacy requirements
