The Finnish logical model for appointments includes a code set for appointment statuses that differs from the FHIR Appointment.status values.

The Finnish logical model is more detailed when the service is being planned, and separates between states where the need fo a service has been identified but no service provider has yet been identified (#1, Suunniteltu), and when the service provider has been selected (#2, Tilattu).

The FHIR specification uses the Appoinment resource to track information on scheduling and for administrative purposes, and the Encounter resource to track any clinically relevant information (see Appointment Statuses and Encounters). In FHIR, when an encounter starts, its state is tracked with the Encounter resource, and no longer with the Appointment.

The Finnish logical model does not make such a distinction. The same value set records states for when the encounter has started (#6, Alkanut) and when the service is in progress or completed (#7, Toteutunut).

The Finnish logical model does not have a separate state for when the patient has arrived (FHIR status #arrived). It does have a code #10 Ilmoittautunut that matches the FHIR code #checked-in.

The Finnish logical model used to have a separate code for an appointment that has been rescheduled (#5, Siirretty), but that code is now deprecated.

The Finnish logical model does not have any code for appointments that have been entered in error.
