Eligibility and benefits can be verified by accessing NaviNet® or by calling the number on the back of the member’s identification card.

Obtaining Authorizations 

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

If you are a Highmark network provider and have not signed up for NaviNet, learn how to do so here.


Highmark recently launched the Auth Automation Hub utilization management tool that allows offices to submit, update, and inquire on authorization requests.
