4.4. Terminology

This section lists the coded value sets that are referenced by the FHIR profiles in this implementation guide. These coded values are used to describe and standardize clinical concepts and other data content within health records.

4.4.1. Usage Guidance

Several ValueSets are not available at their canonical URL (e.g., Canada Health Infoway-published value sets) or on the terminology servers used in implementation guide publication (e.g., tx.fhir.org). Primarily, this impacts validation against Canada Health Infoway-hosted ValueSets during the development of derived Implementation Guides. This does not affect deployed systems as these instances will be validated against loaded terminology. For several of these ValueSets, "stub" resources have been created to stand-in for the unresolvable ValueSets. These stub ValueSets include pointers to the locations where the full value sets can be downloaded. Current guidance is to manually download the value sets from, for example, Infoway's Terminology Server, or Health Canada (e.g. Licensed Natural Health Products). When terminology is not readily available as FHIR® Release 4 ValueSets or CodeSystems, implementers should work with terminology producers to identify options.

• Please note that these value sets and/or code systems are created by Ontario Health.
• Use of terminology subsets hosted on Canada Health Infoway Terminology Server is required in order to comply with this interoperability specification. Access to and use of SNOMED CT and other subsets on Infoway's Terminology Server requires an Infoway account with acceptance of the SNOMED CT license agreements.
