Implement Da Vinci HRex Consent and Provenance resources for data exchange between payers

Verified steps

1. Review the Da Vinci Health Record Exchange (HRex) IG for its Consent and Provenance profile definitions, which govern how member consent for data sharing and data provenance are represented in payer-to-payer and provider-to-payer exchange.
2. Create a Consent resource conforming to the HRex Consent profile to capture the member's authorization for data sharing; include the patient reference, a status of 'active', the scope and category appropriate to the exchange purpose, and the provision specifying what data may be shared and with whom.
3. When requesting data on behalf of a member, include or reference the Consent resource in the exchange request (e.g., as part of a Da Vinci PDex or CDex request) to demonstrate authorization.
4. Create a Provenance resource conforming to the HRex Provenance profile for each FHIR resource shared in the exchange; populate Provenance.agent to identify the source organization, Provenance.target to reference the shared resource, and Provenance.recorded with the exchange timestamp.
5. Link Provenance resources to the exchanged clinical resources so downstream systems can trace the origin and chain of custody of each data element.
6. Validate both Consent and Provenance resources against the HRex IG profiles before submission.
