Expansion based on Filter Operator v5.0.0 (CodeSystem)

Code	System	Display	Definition
=	http://hl7.org/fhir/filter-operator	Equals	The specified property of the code equals the provided value.
is-a	http://hl7.org/fhir/filter-operator	Is 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-of	http://hl7.org/fhir/filter-operator	Descendent 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-a	http://hl7.org/fhir/filter-operator	Not (Is A) (by subsumption)	The specified property of the code does not have an is-a relationship with the provided value.
regex	http://hl7.org/fhir/filter-operator	Regular Expression	The specified property of the code matches the regex specified in the provided value.
in	http://hl7.org/fhir/filter-operator	In Set	The specified property of the code is in the set of codes or concepts specified in the provided value (comma-separated list).
not-in	http://hl7.org/fhir/filter-operator	Not in Set	The specified property of the code is not in the set of codes or concepts specified in the provided value (comma-separated list).
generalizes	http://hl7.org/fhir/filter-operator	Generalizes (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-of	http://hl7.org/fhir/filter-operator	Child Of	Only 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-leaf	http://hl7.org/fhir/filter-operator	Descendent Leaf	Includes 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.
exists	http://hl7.org/fhir/filter-operator	Exists	The 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:

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

Comments

Additional notes about how to use the code
