AIL segment

The AIL segment contains information about location resources (meeting rooms, operating rooms, examination rooms, or other locations) that can be scheduled. Resources included in a transaction using this segment are assumed to be controlled by a schedule on a schedule filler application. Resources not controlled by a schedule are not identified on a schedule request using this segment. Location resources are identified with this specific segment because of the specific encoding of locations used by the HL7 specification.

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 AIL-3 and its value arrives as AIL-2, so the receiver stores Location Resource ID as Segment Action Code.

This page carries the AIL 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 AIL.
