Expansion based on codesystem Filter Operator v6.0.0-ballot2 (CodeSystem)
This value set contains 11 concepts
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 |
