6 segments
A change has been done at the alternate visit identifier level. That is, a PV1-50-alternate visit ID has been found to be incorrect and has been changed.
An A51 event is used to signal a change of an incorrectly assigned alternate visit ID value. The "incorrect source alternate visit ID" value is stored in the MRG segment (MRG-6-prior alternate visit ID) and is to be changed to the "correct target alternate visit ID" value stored in the PV1 segment (PV1-50-alternate visit ID).
