Expansion based on http://hl7.org/fhir/codesystem-hierarchy-meaning version 3.3.0

All codes from system http://hl7.org/fhir/codesystem-hierarchy-meaning

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
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."

Explanation of the columns that may appear on this page:

Lvl

A few code lists that FHIR defines are hierarchical - each code is assigned a level. For value sets, levels are mostly used to organize codes for user convenience, but may follow code system hierarchy - see Code System for further information

Source

The source of the definition of the code (when the value set draws in codes defined elsewhere)

Code

The code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')

Display

The display (used in the display element of a Coding). If there is no display, implementers should not simply display the code, but map the concept into their application

Definition

An explanation of the meaning of the concept
