EHDSMedication to FHIR Medication Mapping

HL7 Europe Base and Core FHIR IG
2.0.0-recon - ci-build 150

HL7 Europe Base and Core FHIR IG, published by HL7 Europe. This guide is not an authorized publication; it is the continuous build for version 2.0.0-recon built by the FHIR (HL7® FHIR® Standard) CI Build. This version is based on the current content of https://github.com/hl7-eu/base/ and changes regularly. See the Directory of published versions

EHDSMedication → MedicationEuCore

Ongoing alignment: The Xt-EHR logical models are under active revision and continuous refinement. Updates from Xt-EHR will be progressively incorporated into this Implementation Guide to maintain alignment with the evolving EHDS specifications.

Yellow row/cells: In this ballot publication, some row/cells of the mapping table have been left in yellow to indicate areas requiring further review or refinement; including feedback from the Xt-EHR joint action (see note above). These highlights will be addressed in subsequent updates to ensure accuracy and completeness of the mappings.

EHDSMedication → MedicationEuCore

This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR MedicationEuCore and OrganizationEuCore profiles used by this Implementation Guide.

Mapping Context

Source logical model: EHDSMedication
Target FHIR profiles: MedicationEuCore

The model supports prescribed/dispensed medication and can represent both generic (virtual) products and branded (real) products.
