This case-sensitive code system http://hl7.org/fhir/code-search-support defines the following codes:

Code Display Definition Copy
explicit in-compose Explicit Codes In Compose The search for code on ValueSet only includes codes explicitly detailed on includes or expansions. returns ValueSet resources where the code is included in the extensional definition of the ValueSet. btn   btn
all in-expansion Implicit Codes In Expansion The search for code on ValueSet only includes all codes based returns ValueSet resources where the code is contained in the ValueSet expansion. btn   btn
in-compose-or-expansion In Compose Or Expansion The search for code on ValueSet returns ValueSet resources where the expansion of code is included in the value set. extensional definition or contained in the ValueSet expansion. btn   btn

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. 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
