Become a part of the Quest Behavioral Health Provider Network.

At Quest, we take care of the caretakers. We can’t take care of our members without you – the skilled behavioral health providers, chemical dependency providers, and EAP providers that matter most to our members.

Quest Behavioral Health is now offering electronic payment processes for Behavioral Health and EAP services. Visit our Electronic Payment Processes page for more information.

For providers who receive paper checks: Checks which are not cashed within 180 days of the issued date will have the funds automatically returned to Quest and a new check will be issued which may delay payment. Attempting to cash a check after 180 days may result in fees. Promptly processing payments from Quest will help to avoid fees or delay of payments. For questions regarding claims payments, please contact Quest at 800-364-6352.

Quest accepts electronic claims for both Behavioral Health and the Employee Assistance Program.
