International Classification of Diseases 9th Revision Clinical Modification
The Minimal Clinical Data (MCD) in Belgium are based on the
International Classification of Diseases -
Version 9 - Clinical Modification, (ICD-9-CM), which is used to code and classify morbidity data.
ICD-9-CM volumes 1 and 2 are used for diagnostic codes, while volume 3 is a system of procedural codes.
The ICD codes were first developed in 1893 in France by the physician Jacques Bertillion (1851-1922).
They were first called the Bertillon Classification of Causes of Death. The first edition, known as the
International List of Causes of Death, was adopted by the International Statistical Institute in 1893.
The World Health Organization (WHO) took over the responsibility for the ICD at its creation in 1948
when the Sixth Revision, which included causes of morbidity for the first time, was published.
The International Classification of Diseases, Clinical Modification (ICD-9-CM) has the following structure:
- Volume 1 is a tabular listing of diagnosis codes, and volume 2 is a diagnosis code index.
- Volume 3 contains procedure codes.
The 2010 ICD-9-CM Volume 1 Diagnosis Codes are grouped into categories. For example ICD-9 code 250.0
means diabetes mellitus with no complications. For diabetes mellitus, a fifth (5th) digit classification is
used, where 250.00 means " diabetes mellitus without mention of complcations" (250.0) and the fifth digit 0 means "type II
or unspecified type, not stated as uncontrolled". The code 530.81 means gastro reflux disease (GERD), whic consists of
the code "other specified disorders of the esophagus" (530.8), further specified into "esophagal reflux" (530.81).
In the case of code 530.81, "reflux esophagitis" (530.11) is excluded.
A V code designates a patient who is accessing the healthcare system for some reason that does not require a diagnosis,
usually a preventive reason. For example V70.0 is the code for a general health check up. The E section, deals with
external causes of injury.The overview below is based on the 2009 editions of ICD-9-CM.
