The authorization is typically obtained by the ordering provider. Some authorization requirements vary by member contract.

Obtaining Authorizations 

Portal: The preferred - and fastest - method to submit preauthorization requests and receive approvals is the online provider portal. The online provider portal (Availity) is designed to facilitate the processing of authorization requests in a timely, efficient manner. Providers who do not have Availity can use the HIPAA Health Services Review (278) electronic transactions for some types of authorizations.


Highmark Blue Cross Blue Shield launched the Predictal Auth Automation Hub utilization management tool that allows offices to submit, update, and inquire on authorization requests. We have a number of resources available to assist providers in the authorization process.
