HL7 Version 2 to FHIR
0.1.0 - STU1 Ballot

This page is part of the HL7 Version 2 to FHIR (v0.1.0: STU 1 Ballot 1) based on FHIR R4. . For a full list of available versions, see the Directory of published versions

Extension: Type

The type was necessary in v2 to distinguish purpose of the observation when it appears in a message in the same group (e.g., answers to ask at order entry questions with actual results ). Within FHIR flagging the observation may not be necessary, but that is not yet clear. Until then, we will keep the thought of needing an extension, but not create it yet.
