## Logical Model: Dosaging model

Official URL: https://www.xt-ehr.eu/specifications/fhir/StructureDefinition/EHDSDosaging | Version: 0.1.0
Draft as of 2025-08-25 | Computable Name: EHDSDosaging

Logical model for usage instructions for administring the requested product. Based on FHIR Dosage complex data type. When implemented, this model may be reduced significantly according to the specific use case.

Usages:

- Use this Logical Model: Medication dispense model, Medication prescription model and Medication statement model

You can also check for usages in the FHIR IG Statistics
