PacificSource supports a growing portfolio of health data interoperability resources to comply with federal regulations and enable the safe exchange of health data, which is important to improving health outcomes.

PacificSource interoperability resources are made available via APIs (Application Programming Interfaces) aligned with HL7 FHIR (Fast Healthcare Interoperability Resources) standards. More information regarding FHIR may be obtained at the HL7 website.

PacificSource APIs provide access to publicly accessible data and—with appropriate security controls—to protected health information (PHI).

PacificSource may block or revoke access to its API resources at any time in the event that it perceives that member PHI may be at risk or that a violation of the Usage Terms and Conditions has occurred.
