A concept descriptor represents any kind of concept usually by giving a code defined in a code system. A concept descriptor can contain the original text or phrase that served as the basis of the coding and one or more translations into different coding systems. A concept descriptor can also contain qualifiers to describe, e.g., the concept of a "left foot" as a postcoordinated term built from the primary code "FOOT" and the qualifier "LEFT". In exceptional cases, the concept descriptor need not contain a code but only the original text describing that concept.

In cases of an exceptional value, the concept descriptor need not contain a code but only the original text describing that concept.
If a value is an exceptional value (NULL-value), this specifies in what way and why proper information is missing.
The plain code symbol defined by the code system. For example, "784.0" is the code symbol of the ICD-9 code "784.0" for headache.
Specifies the code system that defines the code.
If applicable, a version descriptor defined specifically for the given code system.
A name or title for the code, under which the sending system shows the code value to its users.
The valueSet extension adds an attribute for elements with a CD dataType which indicates the particular value set constraining the coded concept.
The valueSetVersion extension adds an attribute for elements with a CD dataType which indicates the version of the particular value set constraining the coded concept.
The text or phrase used as the basis for the coding.
Specifies additional codes that increase the specificity of the the primary code.
A set of other concept descriptors that translate this concept descriptor into other code systems.
