The “Prior authorization list” is a list of designated medical and surgical services and select prescription Drugs that require prior authorization under the medical benefit. The list below includes specific equipment, services, drugs, and procedures requiring review and/or supplemental documentation prior to payment authorization.
Members and providers are encouraged to obtain prior authorization and may call Customer Service to inquire about the need for prior authorization. While the list below covers the medical services, drugs, and procedures that require authorization prior to rendering; Blue Shield may require additional information after the service is provided.
If further information is required to process the payment Blue Shield’s Claims department will reach out and will request the specific information at that time. Before providing service please contact Customer Service or access the provider connection website to verify the service is a covered benefit.
Blue Shield of California providers
Prior authorization for the services listed below is highly recommended. For more information on obtaining prior authorization review refer to your provider manual. If authorization was not obtained prior to the service being rendered, the service will likely be reviewed for medical necessity at the point of claim.
Please include medical records when you are ready to submit for claim payment, review our medical policies, and verify the service is a covered benefit online through our provider connection website or contact Customer Service. If prior authorization was obtained and you are submitting an offline (i.e. paper) claim, remember to attach a copy of the prior authorization letter.
