In an HL7 message, each segment of the message contains one specific category of health information, such as patient information or patient visit data.

The name of each segment in the message is specified by the first field of the segment, which is always three characters long. The following example message contains four HL7 segments:
- MSH
- PID
- NK1
- PV1

It is important to note that different types of HL7 messages contain different HL7 segments. For more information how to determine the HL7 message type, read the following article: [ Ссылка ]
