  • QUOTE: 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 was used to code and classify mortality data from death certificates until 1999, when use of ICD-10 for mortality coding started.

    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 Centers for Medicare and Medicaid Services are the U.S. governmental agencies responsible for overseeing all changes and modifications to the ICD-9-CM.

    Purpose

    ICD-9-CM was developed to code and classify morbidity data from the inpatient and outpatient records, physician offices, and most National Center for Health Statistics (NCHS) surveys.

    As of October 1, 2015, Department of Health and Human Services (HHS) mandated that all entities covered by the Health Insurance Portability and Accountability Act (HIPAA) must transition to a new set of codes for electronic health care transactions in the form of International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) and International Classification of Diseases, Tenth Revision, Procedure Coding System (ICD-10-PCS).

The ICD-9-CM is based on the ICD-9 but provides for additional morbidity detail. It is updated annually on October 1.

    It consists of two or three volumes:

  • Volumes 1 and 2 contain diagnosis codes. (Volume 1 is a tabular listing, and volume 2 is an index.) Extended for ICD-9-CM
  • Volume 3 contains procedure codes for surgical, diagnostic, and therapeutic procedures. ICD-9-CM only
