The United States Core Data for Interoperability (USCDI) is a standardized set of health data classes and constituent data elements for nationwide, interoperable health information exchange. Review the USCDI Fact Sheet to learn more. For data class descriptions and applicable standards supporting data elements, view the USCDI v1 in PDF format. 

  • A USCDI “Data Class” is an aggregation of various Data Elements by a common theme or use case.
  • A USCDI “Data Element” is the most granular level at which a piece of data is exchanged.
    • For example, Date of Birth is a Data Element rather than its component Day, Month, or Year, because Date of Birth is the unit of exchange.

ONC will follow a predictable, transparent, and collaborative process to expand the USCDI, providing stakeholders the opportunity to comment on the USCDI’s expansion. ONC will launch a public website to solicit recommendation from public for changes and additions to the USCDI. Based on public input, the draft of the next version of USCDI will be presented to the public for review and comment before finalizing it. 

The USCDI standard will follow the Standards Version Advancement Process described in the Cures rule to allow health IT developers to update their systems to newer version of USCDI and provide these updates to their customers.
