Description
As part of the v2-to-FHIR project we are mapping commonly used fields in key v2 messages to FHIR resources so that messages can be transformed into bundle of FHIR resources. OBX-10 is the Nature of Abnormal Test field but there is no cognate existing data element in FHIR. We suggest that a standard extension to Observation (and Observation.component) be created to allow exchange of this concept.
The extension should be allowed to repeat to match the cardinality of the v2 spec.
We suggest a CodeableConcept value using value set http://terminology.hl7.org/CodeSystem/v2-0080 with a binding other than Recommended or Extensible (as table 0080 is HL7 defined, but other use cases may have different values).
The v2 description can be reused as part of the extension narrative:
This extension contains the nature of the abnormal test.
