The meaning of the hierarchy of concepts in a code system

This Code system is referenced in the content logical definition of the following value sets:

  • This CodeSystem is not used here; it may be used elsewhere (e.g. specifications and/or implementations that use this content)

This case-sensitive code system http://hl7.org/fhir/codesystem-hierarchy-meaning defines the following codes:

CodeDisplayDefinition
grouped-by Grouped By No particular relationship between the concepts can be assumed, except what can be determined by inspection of the definitions of the elements (possible reasons to use this: importing from a source where this is not defined, or where various parts of the hierarchy have different meanings)
is-a Is-A A hierarchy where the child concepts have an IS-A relationship with the parents - that is, all the properties of the parent are also true for its child concepts
part-of Part Of Child elements list the individual parts of a composite whole (e.g. body site)
classified-with Classified With Child concepts in the hierarchy may have only one parent, and there is a presumption that the code system is a "closed world" meaning all things must be in the hierarchy. This results in concepts such as "not otherwise classified."
