The International Statistical Classification of Diseases and Related Health Problems, 10th revision (ICD-10 of WHO) is an official classification of diagnoses. The German version is a direct translation in German language of the English version of ICD-10 of WHO; its main use in Germany is the encoding of causes of death. The currently valid version in Germany is ICD-10-WHO version 2019.
ICD-10-GM is to be used for encoding in the outpatient and inpatient sectors.
DIMDI publishes the ICD-10-WHO on behalf of the Federal Ministry of Health; it is in the public domain. From 1 January 1998, it has been used in Germany for the encoding of causes of death, thus forming a basis for internationally comparable official statistics of causes of death.
The abbreviation ICD stands for "International Statistical Classification of Diseases and Related Health Problems", the number 10 refers to the 10th revision of the classification. ICD-10 is the follow-up version to ICD-9 and part of the family of international health-related classifications of WHO. It is updated at regular intervals and undergoes fundamental revisions at greater intervals. ICD-10 of WHO is the internationally most frequently used diagnostic classification (mainly for the encoding of mortality).
As a WHO collaboration centre for the system of international classifications, DIMDI works closely with WHO on the further development of ICD-10 and is represented in numerous WHO working groups and committees.
In Germany, ICD-10 is mainly used in two official areas:
For the encoding of causes of death, the unmodified translation in German language of ICD-10 of WHO, known as ICD-10-WHO, is used for the purpose of an internationally comparable statistic of the causes of death. By contrast, in inpatient and outpatient care, the modified version ICD-10-GM is used which is adapted to the requirements of the German healthcare system. Both are official versions.
In addition to ICD-10-GM, there are numerous unofficial special editions of ICD-10 for specialist medical fields for the purpose of documentation.
A very common adaptation of ICD-10 is the "ICD-10 Classification of Mental and Behavioural Disorders - Clinical Descriptions and Diagnostic Guidelines" by WHO.
This special edition for the encoding of diseases (morbidity) in psychosomatics, psychiatry and neurology is based on Chapter V "Mental and Behavioural Disorders" of the official ICD-10 by WHO. In addition, it also contains clinical-diagnostic guidelines. It corresponds with ICD-10 regarding three- and four-character codes. However, for many categories, it contains five-character subcodes not included in the official ICD-10.
This special edition is available from bookshops in a German translation entitled "Internationale Klassifikation psychischer Störungen" (International classification of mental disorders). Its main purpose is the encoding of diagnoses in psychotherapeutic, psychosomatic and psychiatric hospitals as part of medical documentation and reporting.
ICD-10 is the international standard diagnostic classification and permits the systematic recording, analysis, interpretation and comparison of mortality and morbitity data collected in different countries and at different times. One result of such comparison are the reports of the "World Health Statistics" of WHO.
