When everyone's on the same page, technology can make cool things happen. U.S. Core Data for Interoperability – also known by its nickname USCDI - is one of those things.

Epic's work with the HL7® FHIR® standard means that any health system, hospital, or clinic that uses Epic's comprehensive health record system can connect to any app that also supports the HL7 FHIR standard to exchange USCDI data elements.

Epic USCDI on FHIR is a free online resource for developers who create apps for use by healthcare organizations.

Epic supports exchange of the common clinical data set (CCDS) with patient-controlled consumer applications. Find free online resources for developers—including specs, client IDs, a sandbox, and endpoints—on open.epic.
