Reference Tables: ICD-9-CM










The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify diseases and a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or disease. Every health condition can be assigned to a unique category and given a code, up to six characters long. Such categories can include a set of similar diseases.

The ICD-9 was published by the WHO in 1977. According to the World Health Organization Department of Knowledge Management and Sharing, the WHO no longer publishes or distributes the ICD-9 which is now public domain.

ICD-9-CM International Classification of Diseases, Clinical Modification (ICD-9-CM) is a classification used in assigning codes to diagnoses associated with inpatient, outpatient, and physician office utilization in the U.S. The ICD-9-CM is based on the ICD-9 but provides for additional morbidity detail and is annually updated. It was created by the U.S. National Center for Health Statistics as an extension of ICD-9 system so that it can be used to capture more morbidity data and a section of procedure codes was added. This extension was called "ICD-9-CM", with the CM standing for "Clinical Modification".

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).

In Belgium, this table is mainly used in hospital settings as compulsory classification for MHS (Minimum Hospital Summary). This use is defined by FPS Health, Food Chain Safety and Environment.

We only provide here a small extract for illustration purpose. The belgian reference of this table is available on the FPS Health portal.

The version of the table used is specified in the attribute 'SV' of the cd element. In this case, this version number is not the publication number of this site!
