International Classification of Diseases

The International Statistical Classification of Diseases and Related Health Problems (most commonly known by the abbreviation ICD) provides codes to classify diseases and a wide variety of signs, symptoms, abnormal findings, complaints, social circumstances, and external causes of injury or disease. Under this system, every health condition can be assigned to a unique category and given a code, up to six characters long. Such categories can include a set of similar diseases.

The International Classification of Diseases is published by the World Health Organization (WHO) and 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. The ICD is a core classification of the WHO Family of International Classifications (WHO-FIC).

Of special interest is Chapter V, Blocks F00–F99, "Mental and behavioural disorders". The diseases enumerated here correspond to those in the Diagnostic and Statistical Manual of Mental Disorders. Specifically, ICD-10 F64.0, "Transsexualism" corresponds to DSM-IV 302.85, "Gender identity disorder in adolescents and adults".

ICD version 11

Version 11 will be released in 2015. Work started on the revision some time in 2012. Diagnoses related to gender identity have been changed to Gender incongruence. While the diagnosis has been removed from the mental health disorders category, its placement in the category of "Conditions related to sexual health" may not be much better in increasing access to care. The other problem is that the term "incongruence," while accurate, may not translate as intended to non-English speaking countries that use ICD diagnosis criteria.
