| Title | R4B: Associated or related medication information (new) |
| Realm | uv |
| Authority | hl7 |
| Description | R4B: `MedicationKnowledge.relatedMedicationKnowledge` (new:BackboneElement) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `MedicationKnowledge.relatedMedicationKnowledge` as defined in FHIR R4B in FHIR STU3. The source element is defined as: `MedicationKnowledge.relatedMedicationKnowledge` 0..* `BackboneElement` Across FHIR versions, the element set has been mapped as: * R4B: `MedicationKnowledge.relatedMedicationKnowledge` 0..* `BackboneElement` Following are the generation technical comments: Element `MedicationKnowledge.relatedMedicationKnowledge` is not mapped to FHIR STU3, since FHIR R4B `MedicationKnowledge` is not mapped. Element `MedicationKnowledge.relatedMedicationKnowledge` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). |
