Details
This document is the JSON representation specification for the 'Data Types (2.4 - 1.0.0)' CodeSystem provided by HL7. It is specifically used to define the format of observation values within segments such as OBX, OM1, OM3, and OMC in HL7 Version 2.x messaging. The data types defined here are not merely conceptual; they include definitions for various complex structures and identifiers that compose specific medical data, such as Address (AD), Composite (CM), and Date/time range (DR). Other examples include CD, CE, CF, CK. By utilizing this code system, it becomes possible to standardize the type and format of data during data exchange between different electronic health record systems, thereby enhancing interoperability. This specification serves as a technical reference for developers building implementations. In the field of healthcare IT, such standardized code systems are fundamental for achieving seamless data linkage across products from different vendors.
