The HL7HL7 is a Standards Developing Organization accredited by the American National Standards Institute (ANSI) to author consensus-based standards representing a board view from healthcare system stakeholders. HL7 has compiled a collection of message form... More SIU message notifies an auxiliary (or other similarly configured) application of changes to some facet of the filler application’s appointment schedule. There are 14 different trigger events for the SIU message, but they all use a common message format.
The fourteen SIU messages include:
- SIU-S12 – Notification of new appointment booking
- SIU-S13 – Notification of appointment rescheduling
- SIU-S14 – Notification of appointment modification
- SIU-S15 – Notification of appointment cancellation
- SIU-S16 – Notification of appointment discontinuation
- SIU-S17 – Notification of appointment deletion
- SIU-S18 – Notification of addition of service/resource on appointment
- SIU-S19 – Notification of modification of service/resource on appointment
- SIU-S20 – Notification of cancellation of service/resource on appointment
- SIU-S21 – Notification of discontinuation of service/resource on appointment
- SIU-S22 – Notification of deletion of service/resource on appointment
- SIU-S23 – Notification of blocked schedule time slot(s)
- SIU-S24 – Notification of opened (“un-blocked”) schedule time slot(s)
- SIU-S26 – Notification that patient did not show up for scheduled appointment
