DescriptionR4B: `Coverage.costToBeneficiary` (new:BackboneElement)
PurposeThis extension is part of the cross-version definitions generated to enable use of the element `Coverage.costToBeneficiary` as defined in FHIR R4B in FHIR STU3. The source element is defined as: `Coverage.costToBeneficiary` 0..* `BackboneElement` Across FHIR versions, the element set has been mapped as: * R4B: `Coverage.costToBeneficiary` 0..* `BackboneElement` * R4: `Coverage.costToBeneficiary` 0..* `BackboneElement` Following are the generation technical comments: Element `Coverage.costToBeneficiary` has a context of Coverage based on following the parent source element upwards and mapping to `Coverage`. Element `Coverage.costToBeneficiary` has no mapping targets in FHIR STU3. Typically, this is because the element has been added (is a new element).
