Attention Office Administrators and Provider Portal Users: PLEASE ACT NOW

CalOptima Link has been deactivated. It is urgent that you register for CalOptima’s new Provider Portal. Our portal is a secure online web application providing authorized users access to referrals and authorizations, claims history, and member information. All CalOptima Link users for your office will need to register immediately. Please call CalOptima Provider Relations at 714-246-8600 or email  

Please have the following information readily available to complete the registration:

  • Name of authorized contract signer(s)
  • Name of the designee for a Local Office Administrator (LOA) (this is a member of your staff responsible for reviewing and approving requests to access information associated with your office)

Thank you for your attention to this urgent matter. We appreciate your partnership and dedication to providing quality health care for CalOptima members.

Provider Portal has resources and tools so you can submit referrals online, view authorization status, view reports, view claims information, and more.
