| Realm | uv |
| Authority | hl7 |
| Description | R4: `MedicationRequest.dispenseRequest.initialFill` (new:BackboneElement) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `MedicationRequest.dispenseRequest.initialFill` as defined in FHIR R4 in FHIR STU3. The source element is defined as: `MedicationRequest.dispenseRequest.initialFill` 0..1 `BackboneElement` Following are the generation technical comments: Element `MedicationRequest.dispenseRequest.initialFill` has a context of MedicationRequest.dispenseRequest based on following the parent source element upwards and mapping to `MedicationRequest`. Element `MedicationRequest.dispenseRequest.initialFill` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element). |
