## Resource Profile: NCTS Complete Code System 

| | |
| :--- | :--- |
| *Official URL*:https://healthterminologies.gov.au/fhir/StructureDefinition/complete-code-system-4 | *Version*:1.0.0 |
| Active as of 2020-01-31 | *Computable Name*:Ncts_complete_code_system |

 
This StructureDefinition describes the NCTS Complete Code System, a profile of the FHIR® CodeSystem resource. The NCTS Complete Code System is designed to represent terminologies published as part of the National Clinical Terminology Service, and maximise interoperability within the NCTS ecosystem. 

 
The purpose of this profile is to codify a set of general best practices with respect to representing code systems in FHIR, and an opinionated approach to versioning that is compatible with the syndication model that NCTS uses. 

**Usages:**

* Examples for this Profile: [AustralianIndigenousStatus](CodeSystem-australian-indigenous-status-1.md), [AustralianStatesAndTerritories](CodeSystem-australian-states-territories-1.md), [IndividualHealthcareIdentifierRecordStatus](CodeSystem-ihi-record-status-1.md) and [IndividualHealthcareIdentifierStatus](CodeSystem-ihi-status-1.md)
