ICDkoodin

ICDkoodin refers to the International Classification of Diseases (ICD) coding system, specifically the numerical codes used to classify and track diseases, injuries, and other health conditions. The ICD is a medical classification system developed by the World Health Organization (WHO) to promote international comparability in the collection, processing, interpretation, and use of health data. It serves as a standard diagnostic tool for epidemiology, health management, and clinical purposes.

The most recent version, ICD-11, was adopted by the WHO in 2019, replacing the previous edition, ICD-10, which had been in use since 1994. ICD codes are alphanumeric sequences that categorize medical conditions, symptoms, and external causes of injury or disease. For example, "A02.0" represents cholera caused by *Vibrio cholerae* serogroup O1, biovar cholerae, while "S92.411" indicates a specific type of fracture.

ICD codes are widely used in healthcare systems worldwide, including billing, insurance claims, and public health surveillance. They help standardize the recording of medical diagnoses, enabling better data analysis and resource allocation. Hospitals, clinics, and governments rely on these codes to track disease trends, assess healthcare needs, and inform policy decisions.

The system is periodically updated to reflect advances in medical knowledge and changes in disease classification. While ICD-11 introduced significant improvements, such as a more structured format and expanded coverage of mental health and social determinants of health, some countries continue to use earlier versions due to transitional periods or regional adaptations. Proper coding ensures accurate representation of patient conditions, supporting evidence-based healthcare practices.
