**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 the World Health Organization's      Ninth    Revision, International Classification of Diseases (ICD-9). ICD-9-CM is the official    system of assigning codes to diagnoses and procedures associated with hospital utilization    in the United States. The **ICD-9**    is used to code and classify mortality data from death certificates.

The ICD-9-CM consists of:     a tabular    list containing a numerical list of the disease code numbers in tabular form;     an    alphabetical index to the disease entries; and     a    classification system for surgical, diagnostic, and therapeutic procedures (alphabetic    index and tabular list).

The National Center for Health Statistics    (NCHS) and the **Health Care Financing Administration** are    the U.S. governmental agencies responsible for overseeing all changes and modifications to    the ICD-9-CM.
