## EHDSMedicationUse Mapping

EHDSMedicationUse → MedicationStatement
Ongoing alignment: The models are expected to continue evolving, with updates incorporated into this Implementation Guide to maintain alignment with the EHDS Implementing Acts.
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.

### EHDSMedicationUse → MedicationStatement

This page explains how conceptual elements from the EHDS logical model are expressed in the corresponding FHIR MedicationStatement profile used by this Implementation Guide.

Mapping Context

- Source logical model: EHDSMedicationUse
- Target FHIR profile: MedicationStatementEuEps
