Prior authorization to Anthem Blue Cross Blue Shield

Anthem Blue Cross Blue Shield operates as distinct state-licensed plans across many states. Prior authorization requirements, fax numbers, step therapy rules, and covered services differ significantly between California, Ohio, Georgia, Virginia, and every other state Anthem serves. Always confirm which state entity covers the member before submitting — a request routed to the wrong state plan restarts the review clock and can delay care by days.
