3.2.43 ADT/ACK - move patient information - internal ID (event A43)
3 segments
A move has been done at the internal identifier level. That is, a PID-3-patient ID (internal ID) associated with one external identifier (PID-2-patient ID-external ID) has been moved to another external identifier.
An A43 event is used to signal a move of records identified by the MRG-1-prior patient ID-Internal from the "incorrect source external identifier" identified in the MRG segment (MRG-4-prior patient ID-external) to the "correct target external identifier" identified in the PID segment (PID-2-patient ID-external ID).
