AIS segment

The AIS segment contains information about various kinds of services that can be scheduled. Services included in a transaction using this segment are assumed to be controlled by a schedule on a schedule filler application. Services not controlled by a schedule are not identified on a schedule request using this segment.

Count the pipes to find a field, and count the empty ones too: an empty field still holds its place. Leave out the separator before AIS-3 and its value arrives as AIS-2, so the receiver stores Universal Service Identifier as Segment Action Code.

This page carries the AIS field table as published and nothing beyond it. The field notes, vendor behaviour, FHIR mapping and parsing guidance that thePID page has are still to be written for AIS.
