Indirect Exposure Mechanism
1999-04-14
Definition: The patient identified in the PID segment, who experienced the event, might have been exposed to the potential causal product via an intermediary, e.g., a child might be exposed to a product through the placenta or in breast milk, or a transfusion recipient might be exposed via a blood product. If this is the case, the mechanism of product transmission is identified in this field, using the valid values in HL7 table 0253 - Indirect exposure mechanism. If this field is populated, the identity of the person through whom the product was transmitted is contained in NK1 and RXE segments which follow.
