HL7 NK1 Segment

The NK1 segment contains information about the patient’s other related parties, and any associated parties.  If necessary, multiple NK1 segments can be sent to patient accounts using the NK1-1-set ID field. If a person or organization fulfills multiple contact roles, for example, a person is an emergency contact and a next of kin, it is recommended to send a NK1 segment for each contact role (field 7).
