Terminology

Background

The following coded values are used to describe administrative and clinical concepts within the FHIR elements to meet structural requirements of both the data model profiles and user interfaces.

Whenever possible, value sets and code systems were taken from the US Core Terminology and/or FHIR Core Terminology that were associated with the resources for interoperability.

Notes

ValueSet resources have been "expanded" utilizing the ValueSet.expansion element backbone. This is because Azure FHIR Service lacks a terminology server, so any value set that is not extensional required an enumerated lists of all values for display.

Expanded value sets retain their original Canonical URL if they are otherwise unmodified
Any changes to the original value set including adding or removing a code system, defining additional values, or removing values from the ValueSet.compose element is considered a custom value set and will be recorded on Custom Terminology.
