Code Display Definition
= Equals The specified property of the code equals the provided value.
is-a 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 (i.e. include child codes)
descendent-of 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 child codes)
is-not-a Not (Is A) (by subsumption) The specified property of the code does not have an is-a relationship with the provided value.
regex Regular Expression The specified property of the code matches the regex specified in the provided value.
in 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 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).

Explanation of the columns that may appear on this page:

Level Lvl A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes For value sets, levels are under other codes, and imply that the mostly used to organize codes for user convenience, but may follow code they are under also applies 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
