USCDI

The C-CDA templates were designed to meet the 2015 Edition certification criterion for Consolidated CDA Creation 170.315(g)(6). They were created for each item in the 2015 Edition Common Clinical Data Set (CCDS). The C-CDA templates on this page contain requirements up to and including U.S. Core Data for Interoperability (USCDI) v4. Consolidated CDA is based on community input and used for USCDI ONC certification.

Note that:

• USCDI Data Classes and Element names may not be the same as the C-CDA template names and element names.
• Not every USCDI Data Class and Element is mapped to a single template.
• Many C-CDA elements do not map to a USCDI Data Class or Element because C-CDA usage is broader than certification and because additional C-CDA elements are required to make CDA implementable.

ONC’s USCDI and Consolidated CDA are complementary initiatives, with USCDI defining high-level data requirements and Consolidated CDA providing detailed templates for meeting those requirements. Mapping between them is necessary for achieving interoperability and consistency in healthcare data exchange within the United States. Consolidated CDA is broader than USCDI and therefore, to make USCDI implementable in CDA, interpretation of USCDI is necessary. USCDI data classes and element names may not be the same as the Consolidated CDA template and element names.

Updates to C-CDA depend upon community input and we encourage our audience to submit questions and feedback to C-CDA specifications by clicking on the Propose a change link in the footer of every page. In addition, we encourage our audience to request any necessary clarifications to USCDI through the USCDI ONDEC process that helps inform future updates to C-CDA.

The table below lists the C-CDA templates used for the corresponding USCDI Data elements. It is a mapping between USCDI data elements and C-CDA Templates and C-CDA elements.
