ICD-9-CM Medical Diagnosis Codes
The International Statistical Classification of Diseases and Related Health Problems (commonly known as the ICD) provides alpha-numeric codes to classify diseases and a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances and external causes of injury or disease. Nearly every health condition can be assigned to a unique category and given a code, up to six characters long. Such categories usually include a set of similar diseases.
