ICD-9 CM Diagnosis Codes

The International Classification of Diseases, Clinical Modification, 9th Edition (ICD-9-CM), Volumes 1 & 2, is used in assigning codes to diagnoses associated with inpatient, outpatient, and physician office utilization in the USA. The US-based ICD-9-CM is based on the international ICD but provides for additional morbidity detail. ICD-9 is no longer updated since it has been deprecated by ICD-10.

The International Classification of Diseases (ICD) is designed to promote international comparability in the collection, processing, classification, and presentation of mortality statistics.
This includes providing a format for reporting causes of death on the death certificate. The reported conditions are then translated into medical codes through use of the classification structure and the selection and modification rules contained in the applicable revision of the ICD, published by the World Health Organization. These coding rules improve the usefulness of mortality statistics by giving preference to certain categories, by consolidating conditions, and by systematically selecting a single cause of death from a reported sequence of conditions. The single selected cause for tabulation is called the underlying cause of death, and the other reported causes are the non-underlying causes of death. The combination of underlying and non-underlying causes is the multiple causes of death.
