3.2.18 Merge Patient Information (Event Code A18)

5 segments · 1 events

Used to merge current and previous patient ids. This is required, for example, when a patient has previously been registered under a new id because of an error or because there was insufficient time to determine the actual patient id. The merge event occurs when the decision is made to combine the information under either the new or old id.

The PID segment contains the surviving patient id information. The MRG segment contains the non-surviving information.
