CPCDS - USCDI - USCDI +Class and Data Elements Mapping

As part of our comment to USCDI+ Quality, CARIN developed a CPCDS - USCDI - USCDI+ Class and Data Element crosswalk that maps the various Data Classes and Data Elements between CPCDS - USCDI - USCDI+. Of note, it does not map to all the USCDI and USCDI+ Classes and Data Elements, only to those related to CPCDS. We hope this is helpful and are happy to provide a walk through of the crosswalk, if helpful.

Here is a link to the comment:

Mapping is attached.

Thank you again for providing the opportunity to comment on these data elements. We appreciate your consideration and if you have any questions or additional follow-up, please contact a member of our administrative team at or

CARIN Alliance Submission to USCDI

The CARIN Alliance, a multi-sector group of stakeholders representing numerous hospitals, thousands of physicians, and millions of consumers, individuals, and caregivers would like to thank you and the ONC staff for reviewing the data classes and data elements submitted by the CARIN Alliance in September 2021 and April 2022. As part of this submission, we again want to make a recommendation to include the Explanation of Benefit (EOB) data classes and data elements associated with the CARIN IG for Blue Button as part of USCDI version 3.

Additional comment

Additionally, the names for US Core Data for Interoperability (USCDI) and the aligning HL7 US Core FHIR are misleading. The true scope of USCDI is focused largely on EHR interoperabilty and ONC certification of EHRs. However, “US Core” implies core data for the US in general, not the narrow focus on EHRs. For instance, public health and payer use cases are not well represented.

Suggest renaming US Core to something more appropriate to it’s scope, such as US Core for EHR exchange, or expand the scope and make it truly encompassing of the chosen name. At a minimum clearly delineate the scope of USCDI, especially what is not in “US Core” that actually is a core need for the US (in a pandemic, how can public health not be considered core).
