This system defines standard codes used throughout this Implementation Guide for New Zealand rheumatic fever data representation
The codes defined in this CodeSystem are used throughout the rheumatic fever IG, including in resource profiles.
Originally it was sought to define these codes as concepts in the NZ Edition of SNOMED CT. However, this turned out to be unworkable due to restrictions imposed by SNOMED that only 'affiliate members' can access the contents of the SNOMED CT edition. As a consequence of this, applications cannot lookup nor access term definitions on NZHTS – NZ's official terminology server. This prevents FHIR validation of FHIR resources using (or meant to use) NZ edition SNOMED terms/codes.
Due to these restrictions this IG defines codes needed for NZ rheumatic fever data representation locally within the IG, in this CodeSystem.
Some of these codes re-use the original code numbers assigned in the NZ SNOMED edition in case this becomes publically accessible in future.
The codes here are arranged in a 2-layer hierarchy which enables ValueSets segregated by purpose and help consumers understand the various purposes of the codes.
This Code system is referenced in the content logical definition of the following value sets:
