Scheduling AvailableSlots

This data model communicates information about a patient’s office or other outpatient appointment. EHR systems can send Scheduling messages to update your system with the appointment status, date/time, scheduled providers, and scheduled resources.

Every appointment gets assigned a visit number and patient ID. Any changes to the appointment are made with the relevant visit number. If the appointment is canceled and later rescheduled, however, a new visit number is created. Also keep in mind that scheduling holds and blocks don’t have an associated patient ID.

This data model has event types that allow you to:

  • receive a notification about appointment updates;
  • push or receive a list of available appointment slots;
  • query for and receive open appointment times; or
  • query for and receive booked appointment times.

AvailableSlots

Query for open times for booking an appointment within a given time range. Results are returned in Scheduling.AvailableSlotsResponse.
