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
