18.8.87 NK1 - Next of Kin / Associated Parties Segment (3.4.5)

The NK1 segment contains information about the patient's other related parties. Any associated parties may be identified. Utilizing NK1-1 - set ID, multiple NK1 segments can be sent to patient accounts.

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).

18.8.87.2 NK1-1 Set ID - NK1- (SI) 00190 (3.4.5.1)

Definition: This field contains the number that identifies this transaction. For the first occurrence of the segment, the sequence number shall be one, for the second occurrence, the sequence number shall be two, etc.

In addition to allowing repetition of this field for transmitting multiple names with different Name Type Codes, repetition also allows for representing the same name in different character sets based on the value in XPN.8 Name Representation Code.

18.8.87.4 NK1-3 Relationship (CWE) 00192 (3.4.5.3)

Definition: This field contains the actual personal relationship that the next of kin/associated party has to the patient. Refer to User-defined Table 0063 - Relationship in Chapter 2C, Code Tables, for suggested values.
