The FHIR Composition Framework groups resources into which five layers?

• A. Foundation, Core, Clinical, Financial, Specialized
• B. Foundation, Base, Clinical, Financial, Specialized
• C. Foundation, Base, Clinical, Data, Specialized
• D. Foundation, Base, Clinical, Financial, Administrative

Answer: (B)

Grasping how FHIR organizes resources into layered groups helps you see how a document is built from reusable parts. The five layers reflect scope and reuse: Foundation provides the basic scaffolding and metadata that all resources share; Base contains the common data types and elements used across resources; Clinical covers health data that describe patient health events; Financial handles billing, claims, and cost-related resources; Specialized contains resources designed for domain-specific use cases that need unique semantics. This five-layer structure—Foundation, Base, Clinical, Financial, Specialized—follows the established framing, while terms like Core, Data, or Administrative aren’t used to name these layers.
