Record details about an anatomical structure. This resource may be used when a coded concept does not provide the necessary detail needed for the use case.
The BodyStructure resource contains details about the anatomical location of a specimen or body part, including patient information, identifiers, as well as text descriptions and images.
When needed, it allows the the representation of complex body structures and/or locations using the included and excluded elements. It can provide indications of laterality and directionality to the anatomic location. This capability may be required when not indicated in a corresponding code (e.g., includedStructure.structure or excludedStructure.structure). The BodyStructure resource supports recording and tracking an anatomic location or structure on a patient outside the context of another resource. For example, it can be the target of a Procedure or Observation resource.
If a resource's code value implies a body structure, then the bodyStructure resource should be used consistent with the code and to provide any additional detail. The bodySite element in any resource can be used when the resource's code is not implicit about the body structure and does not require extensive detail.
