| Realm | uv |
| Authority | hl7 |
| Description | STU3: `MedicationStatement.dosage` additional types (Dosage) additional types from child elements (additionalInstruction, asNeeded[x], dose[x], maxDosePerAdministration, maxDosePerLifetime, maxDosePerPeriod, method, patientInstruction, rate[x], route, sequence, site, text, timing) |
| Purpose | This extension is part of the cross-version definitions generated to enable use of the element `MedicationStatement.dosage` as defined in FHIR STU3 in FHIR R4B. The source element is defined as: `MedicationStatement.dosage` 0..* `Dosage` Across FHIR versions, the element set has been mapped as: * STU3: `MedicationStatement.dosage` 0..* `Dosage` * R4: `MedicationStatement.dosage` 0..* `Dosage` * R4B: `MedicationStatement.dosage` 0..* `Dosage` Following are the generation technical comments: Element `MedicationStatement.dosage` is mapped to FHIR R4B element `MedicationStatement.dosage` as `SourceIsBroaderThanTarget`. The mappings for `MedicationStatement.dosage` do not cover the following types: Dosage. The mappings for `MedicationStatement.dosage` do not cover the following types based on type expansion: additionalInstruction, asNeeded[x], dose[x], maxDosePerAdministration, maxDosePerLifetime, maxDosePerPeriod, method, patientInstruction, rate[x], route, sequence, site, text, timing. |
