HL7 Version 2 to FHIR
1.0.0-ballot - ballot International flag

HL7 Version 2 to FHIR, published by HL7 International / Orders and Observations. This guide is not an authorized publication; it is the continuous build for version 1.0.0-ballot built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/HL7/v2-to-fhir/ and changes regularly. See the Directory of published versions



v2-to-FHIR will use FHIR components and profiles to maintain mapping documentation. Additionally, when v2 messages are converted to FHIR messages a minmum set of data must be available through the FHIR Bundle. To this end, the following profiles will be introduced in future versions of the guide:

  1. ConceptMap - The ConceptMap is used as the source of truth for the mappings. A profile is defined for each of the mapped elements that defines the data captured for each type of mapping:

    • Message ConceptMap Profile
    • Segment ConceptMap Profile
    • Data Type ConceptMap Profile
    • Code System ConceptMap Profile
  2. Bundle - The profile that must be used to include the minimum data that should be in a FHIR message bundle that represents a converted v2 message.

  3. Other - We are considering how to use MessageDefinition and GraphDefinition and will provide at a future time relevant profiles of these for the FHIR messages that represent the converted v2 messages.
