Abstract

Hl7 v2 is the most widely used healthcare interchange format. Messages are sent in response to trigger events. Messages comprise a set of segments, defined using an abstract message syntax table. Segments contain fields and fields contain components; components may contain sub-components, which are separated by delimiters. Segments are specified in segment definition tables. Z-segments are locally defined. Data types are the basic building blocks in each element. Some are simple, others are complex. Codes are defined using tables.
