## Logical Model: Administered dosage model

Official URL: http://www.xt-ehr.eu/fhir/models/StructureDefinition/EHDSAdministeredDosage | Version: 0.2.1
Draft as of 2026-02-09 | Computable Name: EHDSAdministeredDosage

Model contains elements needed for registering an individual medication administration. It is derived from the full dosage regimen model in order to keep the consistency between the shared elements.

Usages:

- Use this Logical Model: Medication administration model
