ICD-10 is an international statistical classification produced by the World Health Organization. It is used in health care and related industries in several countries around the world. Some have gone on to develop their own national enhancements, building off the international version of the classification.

The fifth chapter of ICD-10 contains the International Classification of Mental and Behavioural Disorders. It is actually the official mental health system for the US as well, but even many professionals do not realize this due to the dominance of the DSM.[1]

WHO have made Chapter V available as two separate publications.[2] The Clinical descriptions and diagnostic guidelines (or "Blue Book") is for clinical and general educational use. The Diagnostic criteria for research (or "Green Book") is intended for research purposes, and to be used in conjunction with the guidelines within it.
