Classifications
The International Statistical Classification of Diseases and Related Health Problems (ICD) is a code list published by the World Health Organization. The ICD is a classification center in the Family of International Classifications of the WHO (in English, WHO-FIC). Under review, the currently used ICD is the tenth edition (ICD-10), developed in 1992 to track mortality statistics.
The ICD provides codes to classify diseases and a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances and external causes of injury or illness. Every health condition can be assigned to a category and give a code of up to five characters in length (format X00.00). Such categories include groups of similar diseases.
It was initially designed as a tool to describe diseases from a public health perspective. It is used worldwide for morbidity and mortality statistics, reimbursement systems and automated decision support in medicine. This system is designed to promote international comparability in the collection, processing, classification and presentation of these statistics.
Classification of mental disorders
An important alternative to the coding of ICD is the diagnostic and Statistical Manual of Mental Disorders (DSM, the English Diagnostic and Statistical Manual of Mental Disorders) by American Psychiatric Association (APA). The DSM system is the primary diagnosis for psychiatric and psychological disorders within the United States, and is used as an adjunct to other diagnostic systems in many countries. Since 1990, the APA and WHO have worked together to combine criteria and make the DSM with certain sections of the ICE, but there are still some differences.
