0. Extension
Definition	The reason that this appointment is being scheduled. This is more clinical than administrative. This can be coded, or as specified using information from another resource. When the patient arrives and the encounter begins it may be used as the admission diagnosis. The indication will typically be a Condition (with other resources referenced in the evidence.detail), or a Procedure.
Short	Reason this appointment is scheduled
Comments	`Appointment.reasonCode` maps to R4 `Appointment.reasonCode`. So is mapped as Equivalent.

Definition	An Extension May be used to represent additional information that is not part of the basic definition of the element.
