Medicine:ICD-10 Chapter V: Mental and behavioural disorders

From HandWiki

This is a shortened version of fifth chapter of the ICD-10: Mental and behavioural disorders. It covers ICD codes F00 to F99. All versions of the ICD-10, including the most recent one (2019), can be browsed freely on the website of the World Health Organisation (WHO). The ICD-10 can also be downloaded in PDF-form.

The WHO has made its classification of mental disorders available in three publications. The first is Chapter V of the ICD-10, which features short summaries of mental disorders, and is intended as a quick reference point. The second is the Clinical descriptions and diagnostic guidelines (CDDG), or the "Blue Book", which is for clinical and educational use. It features longer definitions of mental disorders, along with diagnostic criteria and guidelines. The third is the Diagnostic criteria for research (DCR or DCR-10), or the "Green Book", which is intended for research purposes, and to be used in conjunction with the Blue Book. As with the rest of the ICD-10, both books can be downloaded for free from the website of the WHO.

The codes of this chapter are used by the fifth, most recent version of the Diagnostic and Statistical Manual of Mental Disorders, or DSM-5, which is the primary system for diagnosing mental disorders in the world. The ICD-10 system is used to code these disorders, and strictly seen, the ICD has always been the official system of diagnosing mental diseases in the United States. Due to the dominance of the DSM, however, not even many professionals within psychiatry realize this.[1] The DSM and the ICD form a "dual-system": the DSM is used for diagnostic criteria while the ICD-codes are used for reimbursement claims towards the health insurance companies. The CDDG (Blue Book) also contains diagnostic criteria but for the most part therapists use those in the DSM. This structure has been criticized, with people wondering why there should be two separate systems for the classification of mental disorders. It has been proposed that the ICD supersede the DSM.[2]
