3.2.48 ADT/ACK - change alternate patient ID (event A48)
5 segments
A change has been done at the alternate patient identifier level. That is, a PID-4-alternate patient ID has been found to be incorrect and has been changed.
An A48 event is used to signal a change of an incorrectly assigned alternate patient identifier value. The "incorrect source alternate patient ID" value is stored in the MRG segment (MRG-2-prior alternate patient ID) and is to be changed to the "correct target alternate patient ID" value stored in the PID segment (PID-4-alternate patient ID-PID).
