CodeSystem: Coding System Definition and List of Major Code Systems (v2+)
CodeSystem: Coding System (2.4 - 1.0.0) (Experimental)
Summary
The 'Coding System' provided by HL7 defines a system for specifying coding concepts. This specification outlines the overview and usage of various standard code systems used in healthcare, such as local general codes, ICD-10, and CPT.
Details
This document is a technical specification defining the concept of a 'Coding System' itself, established by HL7. It defines properties like version information and status, and subsequently provides a list of specific coding systems. The major code systems included are numerous, including those essential in clinical settings such as ICD-10 (International Classification of Diseases, 10th Revision) and CPT (Current Procedural Terminology). It also covers analysis codes and method codes defined by specific organizations like ACR (American College of Radiology) and CDC (Centers for Disease Control and Prevention). This specification is noted to be used in the CWE segment within HL7 Version 2.x messaging, serving as a foundation for standardizing concepts and ensuring interoperability in healthcare information exchange. Developers can use this definition to centrally manage code systems from diverse fields.
