Standards status: Trial-use Maturity Level: 0 Computable Name: v3 Code System CodingRationale

Identifies how to interpret the instance of the code, codeSystem value in a set of translations. Since HL7 (or a government body) may mandate that codes from certain code systems be sent in conformant messages, other synonyms that are sent in the translation set need to be distinguished among the originally captured source, the HL7 specified code, or some future role. When this code is NULL, it indicates that the translation is an undefined type. When valued, this property must contain one of the following values: SRC - Source (or original) code HL7 - HL7 Specified or Mandated SH - both HL7 mandated and the original code (precoordination) There may be additional values added to this value set as we work through the use of codes in messages and determine other Use Cases requiring special interpretation of the translations.

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

Properties

This code system defines the following properties for its concepts

OR original and required Originally produced code, required by the specification describing the use of the coded concept.
P post-coded Description: Post-coded from free text source</description>
PR post-coded and required Post-coded from free text source, required by the specification describing the use of the coded concept.
R required Description: Required standard code for HL7.
HL7 HL7 Specified or Mandated HL7 Specified or Mandated true
SH Both HL7 mandated and the original code Both HL7 mandated and the original code (precoordination) true
