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|
