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