The ICD, or International Classification of Diseases, is a global standard for diagnosing and classifying health conditions. Developed by the World Health Organization (WHO), it provides a common language for health professionals to communicate about diseases, injuries, and other health-related issues. The ICD is regularly updated to reflect new medical knowledge and practices. The current version, ICD-11, was released in 2018 and includes more than 55,000 codes for various health conditions. This classification system helps in tracking health statistics, managing healthcare resources, and conducting research. It is used by hospitals, researchers, and policymakers worldwide to improve health outcomes.
