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

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

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