HL7 V2 | CODE TABLES
HL7 v2 code tables
All 628 HL7 version 2 tables, with the codes and meanings for the 421 that have values: patient class, administrative sex, identifier types, event types and the rest.
HL7-defined tables have fixed values. User-defined tables list HL7's suggested values, and sites may use their own. Tables marked none have no HL7 values at all: every site defines its own.
Tip: use your browser's find (Ctrl+F or ⌘F) to search by number or name.
