Status: draft. Extension maintained by: Health Level Seven International (Modeling and Methodology)

A numeric value that allows the comparison (less than, greater than) or other numerical manipulation of a concept (e.g. Adding up components of a score).

Comment :

This extension assigns a numerical value associated with to a concept. Assigning a value to a concept should generally be done in a formal code system that defines the coded ordinal value. value, or in an applicable value set for the concept, but some concepts do not have a formal definition (or are not even represented as a concept formally - often in Questionnaires), so this extension is allowed to appear ouside those preferred contexts. The value may be constrained to an integer in some contexts of use.
