Name | Flags | Card. | Type | Description & Constraints Filter: Bindings Constraints Obligations
--- | --- | --- | --- | ---
EHDSBodyStructure |  | 0..* | Base | Body structure model Instances of this logical model can be the target of a Reference
identifier |  | 0..* | Identifier | Identifier for this instance of the anatomical structure.
morphology |  | 0..1 | CodeableConcept | The kind of structure being represented by the body structure at BodyStructure.location. This can define both normal and abnormal morphologies. Binding Description: (preferred): SNOMED CT
location |  | 0..1 | CodeableConcept | Body site Binding Description: (preferred): SNOMED CT
locationQualifier |  | 0..* | CodeableConcept | Additional qualifier of the body structure (e.g. upper, lower, left side). Binding Description: (preferred): SNOMED CT
laterality |  | 0..1 | CodeableConcept | Body structure laterality (e.g. left, right). Binding Description: (preferred): SNOMED CT
description |  | 0..1 | string | Textual description of the body structure
