Explanation of the columns that may appear on this page:
Level A few code lists that FHIR defines are hierarchical - each code is assigned a level.
In this scheme, some codes are under other codes, and imply that the code they are under also applies
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)
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
