F: Performer HCP declines and CAT redirects

The following sequence diagram shows the messaging flow when the Performer HCP (Service Provider) declines the service request and the CAT redirects to another Performer HCP.See Participants for more information.

Element and Value

Refer to Primary Flow for DocumentReference, HealthcareService, Location, Patient, Practitioner, and PractitionerRole elements.
