Identify the Correct Blue Plan and Regulator in California
California is served by two separate Blue Cross and Blue Shield companies, and the applicable regulator can differ by plan and product. This page explains that structure.
Blue Plans Serving California
Two Separate Companies
Blue Shield of California
Underwritten by California Physicians' Service, operating independently of Anthem.
Why the Legal Entity Matters
Two Companies, Two Possible Regulators
Anthem Blue Cross and Blue Shield of California are separate legal entities with separate member processes, forms, and routing. Product type matters too: HMO products are typically regulated by the Department of Managed Health Care (DMHC) under the Knox-Keene Act, while some PPO or EPO products may be regulated by the California Department of Insurance (CDI) instead. Confirm the legal entity and regulator before assuming which process applies.
Fully Insured vs. Self-Funded
Funding Changes the Regulatory Path
Fully insured plan
The California Blue plan bears the claims risk as the insurer, and either DMHC or CDI regulates it depending on the product.
Self-funded plan
The employer bears the claims risk, and a Blue company may act as administrator. Federal law, not DMHC or CDI, generally governs the appeal.
Home Plan and Host Plan
The Same Qualification Applies in California
The Home Plan commonly controls the member benefit appeal, while the Host Plan may remain involved in provider processing or local network functions for out-of-area care. The denial notice and plan documents govern the specific case.
External Review
DMHC Independent Medical Review, Qualified
For DMHC-regulated fully insured plans, California generally allows up to six months to request an Independent Medical Review (IMR) after the health plan's appeal response. CDI-regulated and self-funded plans follow different rules, so confirm the correct regulator before filing.
FEP Exclusion
FEP Coverage Follows a Different Path
If your coverage is FEP Blue, California's commercial appeal and DMHC or CDI external-review rules don't apply. FEP follows a separate OPM-governed process.
No Universal Route
Local Forms and Routes Remain Case-Specific
This page doesn't publish a specific Anthem Blue Cross or Blue Shield of California mailing address or fax number. Use the route and form referenced in your own denial notice or EOB, or let Remedy Support confirm it during secure review.
Member vs. Provider
Don't Use a Provider Route for a Member Appeal
A provider claims address or provider portal is not a member appeal destination. Using one for a member appeal may delay intake or jeopardize timely filing.
