List of ICD-9 codes 390–459: diseases of the circulatory system
List of ICD-9 codes 390–459: Diseases of the Circulatory System encompasses a range of conditions related to the circulatory system, which includes the heart and blood vessels. These codes were part of the International Classification of Diseases, 9th Revision (ICD-9), a medical classification list by the World Health Organization (WHO). The ICD-9 codes were used to classify diseases and a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or disease until they were succeeded by ICD-10 in 2015. This list is crucial for healthcare professionals, researchers, policymakers, and insurance companies for documentation, reporting, and monitoring purposes.
