International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM)

The International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM) is based on and is compatible with the World Health Organization's International Classification of Diseases, Ninth Revision (ICD-9). The United States currently uses ICD-9-CM to code morbidity diagnoses and inpatient procedures. ICD-9-CM consists of three volumes. Volumes 1 and 2 contain the diagnosis tabular list and index. Volume 3 contains the procedure classification (tabular and index combined).

ICD-9-CM is divided into 17 chapters and 2 supplemental classifications. The chapters are arranged primarily by body system. In addition there are chapters for infectious and parasitic diseases; neoplasms; endocrine, nutritional, and metabolic diseases; mental disorders; complications of pregnancy, childbirth and puerperium; certain conditions originating in the perinatal period; congenital anomalies; and symptoms, signs and ill-defined conditions. The two supplemental classifications are for factors influencing health status and contact with health service and external causes of injury and poisoning.
