Which module describes how terminologies are used in FHIR?

• A. Security and Privacy Module
• B. Workflow Module
• C. Terminology Module
• D. Resource Module

Answer: (C)

Terminology usage in FHIR is described by the Terminology Module. This part of the standard defines how codes from code systems are modeled and applied within resources, including the data types used to represent coded values (Code, Coding, CodeableConcept) and how those values are constrained or expanded through ValueSet, CodeSystem, and ConceptMap resources. It also specifies bindings that attach value sets to elements, guiding validation and interpretation so systems agree on what codes mean. In practice, this module tells you how to reference terminology within resources and how terminology resources relate to the data you exchange. The other modules address different concerns: Security and Privacy handles access control and protection of data, Workflow deals with processes and tasks, and the Resource Module defines the structure of the data resources themselves, not how terminology is used within them.
