# EHDSEncounter -> Encounter (HDR)

**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.

### EHDSEncounter -> Encounter (HDR)

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

**Mapping Context**
*  **Source logical model:** [ EHDSEncounter ](https://www.xt-ehr.eu/fhir/models/StructureDefinition-EHDSEncounter.html) 
*  **Target FHIR profile:** [ EncounterEuHdr ](StructureDefinition-encounter-eu-hdr.md)
