What is Kaiser Permanente Southern California Provider Credentialing?

Credentialing is the process Kaiser uses to verify your qualifications, including your education, licensure, work history, and professional background. It ensures that providers meet their quality and compliance standards before joining the network.

This process is different from enrollment and contracting. While credentialing verifies your eligibility, enrollment allows you to bill, and contracting defines your reimbursement terms.

Any healthcare professional or facility planning to serve Kaiser patients must complete credentialing. This includes physicians, specialists, therapists, behavioral health providers, and group practices.

Even experienced providers transitioning to a new practice or location must reapply, as credentialing is tied to both the individual and practice details.
