Epic Systems is the dominant EHR platform among California's major health systems. UC Health campuses across the state, Sutter Health, Dignity Health, Providence, Cedars-Sinai, UCSF Health, Stanford Health Care, and dozens of other major California healthcare organizations run Epic as their core clinical platform. This widespread Epic adoption has made California one of the largest Epic markets in the country — and has created a substantial need for specialized Epic integration expertise.\n\nZerosums Technology provides Epic integration services specifically for California health systems and medical groups. Our integration engineers understand Epic's architecture deeply, including the Epic Bridges module for HL7 v2 interface management, Epic's SMART on FHIR platform and MyChart API, the Epic Interconnect web services layer, and Epic's native interoperability capabilities through Care Everywhere and Cosmos. We build integrations that work reliably in California's complex health system environments.\n\nCalifornia's health information exchange requirements add specific integration demands for Epic deployments. Connecting Epic to Cal INDEX, participating in California-specific care coordination programs, meeting the interoperability requirements of California's Medi-Cal managed care program, and satisfying CMS and ONC interoperability rules all require specific Epic configuration and interface development work. Our California-specific expertise means we understand these requirements without a learning curve.\n\nFor California digital health companies whose products need to integrate with Epic, we provide development services that navigate Epic's app marketplace process, implement SMART on FHIR authentication, develop FHIR R4 integrations with Epic's APIs, and build the technical documentation required for Epic's review and certification processes. We have guided multiple California health technology companies through the process of building successful Epic integrations.
