The Terminology Module provides an overview and guide to the FHIR resources, operations, coded data types and externally-defined standard and FHIR-defined terminologies that are used for representing and communicating coded, structured data in the FHIR core specification and profiles. Collectively, these capabilities are used to provide the terminology service functionality required for supporting the use of coded data in FHIR resources throughout the specification as described in the other modules.
The terminology resources and their relationships are shown below:
The Terminology Module covers the following:
Coded Data Types
A subset of the terminology resources has been tested and are being used in production tooling, and as such have reached a maturity level where changes become less likely. These are:
Other resources are still under development:
Over the next 18 months, we will continue to advance the resources through the Maturity Levels through further development and testing. We anticipate more widespread implementation of NamingSystem, CodeSystem and ExpansionProfile and testing in Connectathons and with implementation experience.
