HL7 v2 chapters
The standard is one long document, split into fifteen chapters that each cover a different part of hospital work.
Segments, trigger events and code tables each belong to a chapter. Admissions are chapter 3, orders are chapter 4, results are chapter 7, and knowing that is most of the work of looking something up. Start with the subject you are working on.
