Code Display Definition

true true Boolean true.

false false Boolean false.

trace Trace Amount Detected The content is greater than zero, but too small to be quantified.

sufficient Sufficient Quantity The specific quantity is not known, but is known to be non-zero and is not specified because it makes up the bulk of the material.

withdrawn Value Withdrawn The value is no longer available.

nil-known Nil Known The are no known applicable values in this context.

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
