Introducing a new provider resource experience that simplifies getting you the information you need, when you need it. You’re invited to visit an early release of our new site; try it out at Your feedback is appreciated as we work to complete the experience.

Authorization Requirements

Highmark requires authorization of certain services, procedures, and/or Durable Medical Equipment, Prosthetics, Orthotics, & Supplies (DMEPOS) prior to performing the procedure or service. The authorization is typically obtained by the ordering provider. Some authorization requirements vary by member contract. This information is intended to serve as a reference summary that outlines where information about Highmark’s authorization requirements can be found. (This information should not be relied on as authorization for health care services and is not a guarantee of payment.)


MCG Clinical Criteria - Information on Highmark's incorporation of MCG Health evidence-based clinical guidelines into Highmark’s criteria of clinical decision support.


Member Eligibility and Benefits

Service preapproval is based on the member’s benefit plan/eligibility at the time the service is reviewed/approved. Benefit plans vary widely and are subject to change based on the contract effective dates. The provider is responsible for verification of member eligibility and covered benefits.

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


Prior Authorization Code Lists

The procedure codes contained in the lists below usually require authorization (based on the member’s benefit plan/eligibility). Effective dates are subject to change. Highmark will provide written notice when codes are added to the list; deletions are announced via online publication.


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 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.
