The Office for the National Coordinator for Health Information Technology (ONC) finalized version 4 of the United States Core Data for Interoperability (USCDI) on July 20.

The ONC adopted the USCDI standard following passage of the 21st Century Cures Act to standardize a set of data classes for health care to be formatted for nationwide electronic exchange. New versions of the USCDI have been published annually, with an open submission system to collect public submission proposals for new data classes and elements.

Version 4 features 20 additional data elements and a new data class. The new data class, “Facility Information,” provides details on the physical location of available services or resources. Also of note are six new data elements applicable to laboratories, intended to support ongoing public health reporting and to further specify collected laboratory specimens.

The USCDI New Data Element and Class submission system is now open and accepting feedback for version 5. All submissions for new data elements and feedback on existing data elements must be received by Sept. 20, 2023.
