ZL7 segment

(proposed example only)

The shape of one line

segmentZL7|ZL7-1Primary key value - ZL7|ZL7-2Display-sort-key

required

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 ZL7-2 and its value arrives as ZL7-1, so the receiver stores Display-sort-key as Primary key value - ZL7.

This page carries the ZL7 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 ZL7.

No message structure in v2.5.1 carries ZL7, and no other segment is linked to it here. The standard defines the segment on its own.
