HL7 Unified Terminology

Introduction

This is the main entry page for the new HL7 Terminology. This page is still under construction, and will change frequently.

PLEASE NOTE: This page is a demonstration page to illustrate the UTG prototype progress. There are no HL7 Terminology releases or downloadable/browsable content accessible through these pages at this time. For illustrative purposes only!

General Information

HL7 is in the process of unifying the governance of the terminology artifacts used and referenced in its published standards. One goal of this effort is to provide a single entry point for the user community to access all of the HL7 terminology artifacts in a common browsing and downloadable format. The links on this page will direct you to the terminology content maintained and published by HL7.

Browsable Terminology

These are the pages listing the HL7 Code Systems and Value Sets. The links on these pages will access the same content pages as the canonical URIs of the terminology objects themselves. These reference the most recent release of the HL7 terminology.

Be advised that for the initial demonstration prototype, the html pages generation for the UTG content in not yet working. For illustrative purposes, the links below reference the FHIR rendered terminology pages in order to show the format that the UTG terminology at the valid URLs for the code systems and value sets will look like once the html generation software has been completed. Sorry for the delay.

Downloadable Terminology

The links here are to download the HL7 Terminology. At the present time, only the download of all terminology is supported; downloading only selected code systems and value sets is planned for the near future. Please note that at this time the download links access zip files of the initial prototype UTG resources files, still in development so incomplete and containing varying errors. Note that only the V3 and the V2 vocablary are in these, and only the HL7 maintained content, not any external content.
