Epic Systems is the dominant EHR platform among major health systems, academic medical centers, and large multi-specialty groups in the United States. Epic's native functionality is extensive, but virtually every healthcare organization running Epic also needs to exchange data with systems that Epic doesn't natively replace — specialized departmental systems, legacy clinical applications, insurance carriers, public health agencies, reference laboratories, imaging centers, and an ever-growing ecosystem of digital health platforms.\n\nZerosums Technology provides specialized integration engineering services for Epic environments. Our team has deep experience with Epic's integration architecture, including Epic's Bridges module for HL7 v2 interface management, MyChart API and Patient-Facing FHIR APIs, Epic's App Market and third-party vendor integration patterns, and the Interconnect web services platform. We build integrations that are reliable, well-documented, and maintainable over the long lifecycle of an Epic implementation.\n\nHL7 v2 interfaces remain the workhorse of Epic integration. We develop and maintain the full range of Epic HL7 interface types: ADT feeds to downstream systems, order and result interfaces with reference labs, radiology RIS integrations, pharmacy system connections, billing and coding interfaces, and more. Our interfaces are built with appropriate error handling, alerting, and documentation so your team can manage them confidently.\n\nFor organizations adopting modern interoperability approaches, we develop FHIR R4 integrations that leverage Epic's SMART on FHIR platform and FHIR APIs. This includes patient access apps, provider-facing clinical decision support tools, population health analytics pipelines, and care coordination platforms that need real-time access to Epic data. We also help Epic customers satisfy the ONC 21st Century Cures Act FHIR API requirements.
