## Logical Model: Medication Line (model) 

| | |
| :--- | :--- |
| *Official URL*:https://www.ehealth.fgov.be/standards/fhir/medication/StructureDefinition/BeModelMedicationLine | *Version*:1.1.0 |
| Active as of 2026-03-25 | *Computable Name*:MedicationLine |

 
Logical data model for medication line. 

### Relationship with other elements:

The Medication Line relates to the other data structures in the following way:

* [Medication Line](StructureDefinition-BeModelMedicationDispense.md) may refer to a [Medication Dispense](StructureDefinition-BeModelMedicationDispense.md) that occurs in the treatment.
* [Medication Dispense](StructureDefinition-BeModelMedicationDispense.md) may be the trigger for creating or updating a [Medication Line](StructureDefinition-BeModelMedicationLine.md).

**Usages:**

* Refer to this Logical Model: [Medication Dispense (model)](StructureDefinition-BeModelMedicationDispense.md) and [Medication prescription (model)](StructureDefinition-BeModelMedicationPrescription.md)
