ISD segment

The interaction detail segment contains information about the status of specific interaction (e.g., processing — see section Glossary) on the specific equipment.

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 ISD-2 and its value arrives as ISD-1, so the receiver stores Interaction Type Identifier as Reference Interaction Number.

This page carries the ISD 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 ISD.
