Data Types
243 data types in HL7 v2.4
§2A.3 Data Types:Data types define the format and structure of values within message fields. They range from simple primitives (ST, NM, DT) to complex composite types (XPN, XAD, CX) that contain multiple components. Understanding data types is essential for correctly parsing and constructing HL7 messages.
