Highmark Blue Cross Blue Shield Prior Authorization

Highmark Blue Cross Blue Shield prior authorization rules are often service-specific rather than universal, so the safest workflow is to confirm the requirement in the payer's provider resources before scheduling or submitting care. The notes below summarize the most actionable provider-side guidance captured in the research set for this payer.

At a glance

• Prior authorization is primarily handled through Availity Essentials / Availity’s Authorizations & Referrals workflow for initial medical authorization requests. Highmark’s Provider Resource Center directs providers to authorization guidance and medical policies, with some products requiring specific electronic submission rules. Pharmacy authorizations are handled through CoverMyMeds via Highmark’s Payer Spaces in Availity. Fax forms exist as a backup in some cases, but West Virginia prior authorization forms were removed because electronic submission is required there.
• Authorization requirements vary by product, service area, and procedure code; Highmark directs providers to medical policies and code-specific guidance.
• West Virginia prior authorization forms were removed from the PRC; fax is not accepted for WV providers for prior auth submissions.
• Some content is available only after logging into Availity.
