The meaning of the hierarchy of concepts in a code system.
Official specComposition
| Code | Display | Definition |
|---|---|---|
| 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. Not that is-a is a property of the concepts, so additional subsumption relationships may be defined using properties or the [subsumes](extension-codesystem-subsumes.html) extension. |
| 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.". |
