CNS segment

The clear equipment notification segment contains the data necessary to allow the receiving equipment to clear any associated notifications. 13.4.8.0 CNS Field Definitions 13.4.8.1 CNS-1 Starting Notification Reference Number (NM) 01402 Definition: This field contains the starting notification reference number that is to be cleared. 13.4.8.2 CNS-2 Ending Notification Reference Number (NM) 01403

The shape of one line

segmentCNS|CNS-1Starting Notification Reference…|CNS-2Ending Notification Reference…|CNS-3Starting Notification Date/Time|CNS-4Ending Notification Date/Time|CNS-5Starting Notification Code|CNS-6Ending Notification Code

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 CNS-2 and its value arrives as CNS-1, so the receiver stores Ending Notification Reference Number as Starting Notification Reference Number.

This page carries the CNS 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 CNS.
