## EHDSMedicationUse Mapping

EHDSMedicationUse → MedicationStatement

### 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
