CodeDisplayDefinition
=EqualsThe specified property of the code equals the provided value.
is-aIs A (by subsumption)Includes all concept ids that have a transitive is-a relationship with the concept Id provided as the value, including the provided concept itself (include descendant codes and self).
descendent-ofDescendent Of (by subsumption)Includes all concept ids that have a transitive is-a relationship with the concept Id provided as the value, excluding the provided concept itself i.e. include descendant codes only).
is-not-aNot (Is A) (by subsumption)The specified property of the code does not have an is-a relationship with the provided value.
regexRegular ExpressionThe specified property of the code matches the regex specified in the provided value.
inIn SetThe specified property of the code is in the set of codes or concepts specified in the provided value (comma separated list).
not-inNot in SetThe specified property of the code is not in the set of codes or concepts specified in the provided value (comma separated list).
generalizesGeneralizes (by Subsumption)Includes all concept ids that have a transitive is-a relationship from the concept Id provided as the value, including the provided concept itself (i.e. include ancestor codes and self).
child-ofChild OfOnly concepts with a direct hierarchical relationship to the index code and no other concepts. This does not include the index code in the output.
descendent-leafDescendent LeafIncludes concept ids that have a transitive is-a relationship with the concept Id provided as the value, but which do not have any concept ids with transitive is-a relationships with themselves.
existsExistsThe specified property of the code has at least one value (if the specified value is true; if the specified value is false, then matches when the specified property of the code has no values).

Explanation of the columns that may appear on this page:

LvlA 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
SourceThe source of the definition of the code (when the value set draws in codes defined elsewhere)
CodeThe code (used as the code in the resource instance). If the code is in italics, this indicates that the code is not selectable ('Abstract')
DisplayThe 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
