BLC segment

The BLC segment contains data necessary to communicate patient abstract blood information used for billing and reimbursement purposes. This segment is repeating to report blood product codes and the associated blood units.

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 BLC-2 and its value arrives as BLC-1, so the receiver stores Blood Amount as Blood Product Code.

This page carries the BLC 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 BLC.
