Status	draft (experimental) · 1.26.0
Base	Extension (constraint)
Context	Appointment (element)
Source	FSH · JSON

Delivery channel of an appointment/encounter (in-person | video | telephone | secure message). A distinct axis from appointmentType (booking style); R5 models this as Appointment.virtualService. Value is CodeableConcept so a source/raw code and a normalized Nexus code co-exist; the binding is extensible so a future pan-Canadian/Ontario code can be added as a parallel coding.
