About CalOptima Link

Support and resources

Important Update

CalOptima is required to protect the privacy and security of our member’s protected health information by implementing the following changes to the CalOptima Link Provider Portal:

  • CalOptima Link no longer displays the member’s street address, telephone number or clinical summaries. Claims inquiries are now a stand-alone function of the Provider Portal which requires a new registration to access.
  • To register for claims function, click on the “Register for CalOptima Link” arrow below and create a new log in, using your same NPI and TIN (Note: There may be time-delay due to volume of registrations.)

For any questions and to check claim status, please call the Claims department at 714-246-8885.

CalOptima Link has resources and tools so you can submit referrals online, view authorization status, view clinical alerts at a glance, create reports, view referral information, and more.

Download the CalOptima Link user guide .  

After we receive your registration request, we will contact you by phone. To adhere to security standards for access to CalOptima Link, our customer support staff will request confirmation of employment or affiliation on company letterhead. This will ensure access only to the appropriate staff in your office.

For registration questions or technical support, please call 800-864-8160.
