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

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

This section of the wiki contains the content of the TermInfo, Release 1.5, broken into individual word documents. There is one document per chapter of the TOC. These files will be used to facilitate updating of the material from version 1.5 of the TermInfo Implementation Guide (Initially named, Using SNOMED CT in HL7 Version 3; Implementation Guide, Release 1.5) . Updates will be based on ballot comment reconciliations from the 2009 Ballot and other currently relevant improvements.
