HL7 Terminology (THO)
5.1.0 - Publication International flag

This page is part of the HL7 Terminology (v5.1.0: Release) based on FHIR R4. The current version which supercedes this version is 5.2.0. For a full list of available versions, see the Directory of published versions

ValueSet: CodingRationale

Official URL: http://terminology.hl7.org/ValueSet/v3-CodingRationale Version: 2.0.0
Active as of 2014-03-26 Computable Name: CodingRationale
Other Identifiers: id: urn:oid:2.16.840.1.113883.1.11.19250

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 value set is not used here; it may be used elsewhere (e.g. specifications and/or implementations that use this content)

Logical Definition (CLD)



This value set contains 8 concepts

Explanation of the columns that may appear on this page:

Level A few code lists that FHIR defines are hierarchical - each code is assigned a level. In this scheme, some codes are under other codes, and imply that the code they are under also applies
System 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)
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
