International Classification of Diseases, ICD-10, chapter V
The classification UK and European services worked to for thirty years, and the one much of the record is still coded in.
ICD-10 chapter V classifies mental and behavioural disorders for the World Health Organization, assigning each condition an alphanumeric F-code: the letter F followed by two digits at the three-character level, with further digits after a decimal point for finer distinctions. The ten blocks run from F00 to F09 for organic disorders through F90 to F98 for disorders of childhood, closing at F99. It exists in two companion forms. The blue book sets out clinical descriptions and diagnostic guidelines, written to keep judgement with the clinician; a separate volume gives tighter diagnostic criteria for research.
WHO endorsed the tenth revision in 1990 and published the mental disorders volume in 1992, after field trials across roughly forty countries. Across the UK and much of Europe, F-codes carry the diagnosis through referral letters, discharge summaries and the case record. The structure and terminology differ from the American DSM, so a code read in one frame does not map cleanly onto the other.
