TermInfo – Implementation Guide for Using SNOMED CT and LOINC Terminologies in HL7 Information Models

The new and expanded project officially began at the January 2012 WGM in San Antonio. The intent is to develop material for DSTU followed by normative ballot to address issues of overlap between the terminology and information models.

The links below are to the content from the previous DSTU standard (expired May 2009), which will serve as the starting point for our new work:

Hot Topics

FHIR TermInfo-related Issues

Use Cases

Each use case needs to be given a meaningful name, then linked out to a page for that use case.


Presentations given to explain TermInfo will be posted here.


A summary is posted here of the principles which form the basis upon which TermInfo is built.

TermInfo 1.5 DSTU - Update Project (archive)

TermInfo January 2014 5th DSTU Ballot Updates

This section of the wiki contains the content of the TermInfo January 2014 5th DSTU Ballot, broken into individual Word documents. There is one document per chapter of the TOC. These files will be used to facilitate incorporation of the Jan. 2014 ballot comment resolutions into the final DSTU version that is being prepared for official HL7 and IHTSDO publication.

We are using a Google Docs spreadsheet for tracking progress with the document updates as they are being made to apply the ballot comment resolutions.

This is the final January 2014 balloted version (in Word format) of the TermInfo DSTU draft document (the source of the individual sections below):
