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 VTQ-2 and its value arrives as VTQ-1, so the receiver stores Query/Response Format Code as Query Tag.

This page carries the VTQ 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 VTQ.

No message structure in v2.5.1 carries VTQ, and no other segment is linked to it here. The standard defines the segment on its own.
