ICD codes, or International Classification of Diseases codes, are a standardized system used by healthcare providers to classify and code diagnoses, symptoms, and procedures. These codes help in documenting patient information, facilitating billing, and conducting research. Each code corresponds to a specific health condition, making it easier to track disease prevalence and treatment outcomes. The World Health Organization (WHO) oversees the development and updates of the ICD system. The latest version, ICD-11, was released in 2019 and includes new codes and categories to reflect advancements in medical knowledge and technology. This system is essential for maintaining consistent health records globally.
