Dental Providers – IMPORTANT

Dental Providers who intend to bill for both medical and dental services for Highmark Blue Cross Blue Shield of Western New York members will need to follow a new process to be credentialed and contracted.



Professional Providers

Providers who are currently credentialed with Highmark Blue Cross Blue Shield of Western New York will not need to recredential until you are normally due to recredential with us. You will need to continue doing this through the usual CAQH process. Once you have attested/updated your information in CAQH, there is nothing else you need to do.

You can always reference the Highmark Affiliation FAQs for more information.
