Overview
This is an overview of IGUHealth Terminology module support. For a descriptive definition of the terminology module with FHIR click here. In short, terminologies are a defined set (ValueSet, CodeSystem) of fixed string values (codes). The terminology module defines ways for looking up, validating, pulling in additional information, and translating between terminology sets (see here).
