In most cases, Da Vinci will use the US Core Coverage profile when communicating Coverage.

This profile is intended for use ONLY during the $member-match operation. It differs from the US Core profile in that the referenced 'Patient' resource does not need to have an identifier (as when calling $member-match, no identifier will be known).

This structure is derived from Coverage

Summary

Mandatory: 1 element(2 nested mandatory elements)
Must-Support: 19 elements

Structures

This structure refers to these other structures:

• US Core Patient Profile (http://hl7.org/fhir/us/core/StructureDefinition/us-core-patient|7.0.0)
• HRex Organization Profile (http://hl7.org/fhir/us/davinci-hrex/StructureDefinition/hrex-organization)
• US Core RelatedPerson Profile (http://hl7.org/fhir/us/core/StructureDefinition/us-core-relatedperson|7.0.0)
• HRex Member Match Patient (http://hl7.org/fhir/us/davinci-hrex/StructureDefinition/hrex-patient-demographics)

Slices

This structure defines the following Slices:

• The element 1 is sliced based on the value of Coverage.identifier
• The element 1 is sliced based on the value of Coverage.class

Maturity: 2

If the member identifier (conveyed in Coverage.identifier) is known, it must be sent as this uniquely identifies a covered individual. If not, then the Coverage.subscriberId can be used together with demographic information found by resolving Coverage.beneficiary to identify the member. (There can be multiple members associated with a single subscriber - e.g. family members of an individual who is covered under a work-based policy.)

Additional notes and guidance around how to map real-world insurance card information into the Coverage resource can be found in the CARIN Digital Insurance Card IG. As a rule, all elements available SHOULD be populated, even if not all might be strictly necessary to identify the member because rules can vary from insurer to insurer about which pieces of information are necessary to uniquely identify a member.
