Blue Shield of California Service Not Covered: How to Appeal

Why Blue Shield of California Denies Not Covered Claims

Blue Shield of California denies service not covered claims when it determines the request does not meet its internal coverage criteria. This may involve a medical necessity determination, a prior authorization requirement, a network limitation, or a policy exclusion.

Common Denial Reasons

• Not medically necessary: Blue Shield of California's clinical reviewers determined the service did not meet coverage criteria
• Prior authorization not obtained or denied: Advance approval was required but not received
• Out-of-network provider: The treating provider or facility is not in Blue Shield of California's network
• Plan exclusion: The service is excluded under your specific Blue Shield of California plan
• Missing documentation: Insufficient clinical records were submitted to support the claim

Steps to Appeal

1. Get the denial in writing — Request Blue Shield of California's denial letter with the specific reason and policy provision cited
2. Request the clinical policy document — Blue Shield of California must provide the internal criteria applied to your claim
3. Obtain a letter of medical necessity — Your treating physician should directly address the denial reason
4. File an internal appeal — Submit within 180 days of the denial notice. Urgent appeals must be processed within 72 hours
5. Request external review — If the internal appeal fails, request independent external review
