3.2.30 ADT/ACK - merge person information (event A30)
3 segments
Event A30 is being retained for backward compatibility. An A30 event can be used to merge person information on an MPI. The A34 (merge patient information-patient ID only), A35 (merge patient information-account number only), A36 (merge patient information-patient ID & account number), A40 (merge patient-patient identifier list), A41 (merge account-patient account number) and A42 (merge visit-visit number) events should be used to merge patient information for a current episode. The "incorrect MRN" identified on the MRG segment (MRG-1-prior patient identifier list) is to be merged with the "correct MRN" identified on the PID segment (PID-3-patient identifier list). The "incorrect MRN" then no longer exists. All PID data associated with the "correct MRN" are treated as updated information.
The MRNs involved may or may not have active or inactive cases associated with them. Any episode of care that was previously associated with the "incorrect MRN" is now associated with the "correct MRN." A list of these cases is not provided.
