HL7-defined code system of comcepts that represent an exception identifier code; that is, a code that is not defined in the value set (either model or site-extended). These are occationsally referred to a 'flavors of null' although this set of concepts is specific to the CWE datatype used in HL7 Version 2.x messaging, and the codes may be used in the 'identifier' component of the 'triplets' in that datatype.

This Code system is referenced in the content logical definition of the following value sets:
