5 segments

A change has been done at the account identifier level. That is, a PID-18-patient account number has been found to be incorrect and has been changed.

An A49 event is used to signal a change of an incorrectly assigned account number value. The "incorrect source account number" value is stored in the MRG segment (MRG-3-prior patient account number) and is to be changed to the "correct target account number" value stored in the PID segment (PID-18-patient account number).
