TQ2 segment

The TQ2 segment is used to form a relationship between the service request the TQ1/TQ2 segments are associated with, and other service requests. The TQ2 segment will link the current service request with one or more other service requests. There are many situations, such as the creation of a service request for a group of intravenous (IV) solutions, where the sequence of the individual intravenous solutions (each a service in itself) needs to be specified, e.g., hyperalimentation with multi-vitamins in every third bottle.

The shape of one line

required in some cases optional

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 TQ2-3 and its value arrives as TQ2-2, so the receiver stores Related Placer Number as Sequence/Results Flag.

This page carries the TQ2 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 TQ2.
