Linking Appointment with Encounter

juan londonoDec 4 2025

Following the documentation for through R4 API, when I query an Appointment (for example GET https://fhir-open.cerner.com/r4/ec2458f2-1e24-41c8-b71b-0e701af7583d/Appointment/4822366 ) or an Encounter (for example GET https://fhir-open.cerner.com/r4/ec2458f2-1e24-41c8-b71b-0e701af7583d/Encounter/97939518 only Encounter has a reference to Appointment but it's always empty; a similar question was posted here https://forums.oracle.com/ords/apexds/post/associating-encounter-and-appointment-through-r4-api-7377 but I was wondering if there's a solution from Appointment to Encounter or any other way to associate them.

Thanks
