NLM released VSAC update version 2.19.0 on June 28, 2019

NEW: C-CDA R2.1 Updated Value Sets Available

We are pleased to announce the VSAC publication and downloadable files of the 2019-06-28 release of the HL7 Consolidated Clinical Document Architecture (C-CDA) R2.1 value sets, authored by the HL7 Terminology group.

There are several ways you can access the C-CDA value sets:

• VSAC Welcome Page: The Search button of the HL7 C-CDA Value Sets program block leads you to the VSAC Search Value Sets web browser, presorted by this HL7 C-CDA release. The Download link leads you to the C-CDA release section of the Download tab and supplies pr-packaged downloadable files.
• VSAC Download Tab: Here, you can download the Excel and pipe-delimited text files, code system versions used, and a list of C-CDA value sets available (136) and unavailable (8) in VSAC. The published downloadable C-CDA R2.1 2019-06-28 release excludes eight C-CDA value sets for which VSAC does not have the required supporting code systems.
• VSAC Search Value Sets Tab: Use a web browser to search, sort, filter and view details for all or individual value sets; use the Export Search Results button to download a catalog of C-CDA value set expansions; increase the paging and use the checkboxes to download all C-CDA value set expansions as Excel, XML, or Text files. Navigate to the Search Value Sets tab, select the HL7 C-CDA program, and select the C-CDA R2.1 2019-06-28 release
• VSAC SVS API: Given a C-CDA value set identifier (OID) that you can obtain by any of the above methods, use an SVS API call, such as:
  https://vsac.nlm.nih.gov/vsac/svs/RetrieveMultipleValueSets?id=2.16.840.1.113883.1.11.16866&release=C-CDA R2.1 2019-06-28&ticket={{ST}}
