This block contains a wide variety of disorders that differ in severity (from uncomplicated intoxication and harmful use to obvious psychotic disorders and dementia), but that are all attributable to the use of one or more psychoactive substances (which may or may not have been medically prescribed). The substance involved is indicated by means o...
Identification of the psychoactive substance used may be made on the basis of self-report data, objective analysis of specimens of urine, blood, etc, or other evidence (presence of drug samples in the patient’s possession, clinical signs and symptoms, or reports from informed third parties). It is always advisable to seek corroboration from more th...
Acute intoxication is usually closely related to dose levels (see ICD-10, Chapter XX). Exceptions to this may occur in individuals with certain underlying organic conditions (e.g. renal or hepatic insufficiency) in whom small doses of a substance may produce a disproportionately severe intoxicating effect. Disinhibition due to social context sh...
Applies only to alcohol. Sudden onset of aggression and often violent behaviour that is not typical of the individual when sober, very soon after drinking amounts of alcohol that would not produce intoxication in most people.
A pattern of psychoactive substance use that is causing damage to health. The damage may be physical (as in cases of hepatitis from the self-administration of injected drugs) or mental (e.g. episodes of depressive disorder secondary to heavy consumption of alcohol).
cluster of physiological, behavioural, and cognitive phenomena in which the use of substance or a class of substances takes on a much higher priority for a given individual than other behaviours that once had greater value. A central descriptive characteristic of the dependence syndrome is the desire (often strong, sometimes overpowering) to take p...
definite diagnosis of dependence should usually be made only if three or more of the following have been present together at some time during the previous year: a strong desire or sense of compulsion to take the substance; difficulties in controlling substance-taking behaviour in terms of its onset, termination, or levels of use; a physiological wi...
(e.g. in hospital, in a therapeutic community, in prison, etc.)
(e.g. with methadone; nicotine gum or nicotine patch)
A group of symptoms of variable clustering and severity occurring on absolute or relative withdrawal of a substance after repeated, and usually prolonged and/or high-dose, use of that substance. Onset and course of the withdrawal state are time-limited and are related to the type of substance and the dose being used immediately before abstinence. T...
Withdrawal state is one of the indicators of dependence syndrome (see F1x.2) and this latter diagnosis should also be considered. Withdrawal state should be coded as the main diagnosis if it is the reason for referral and sufficiently severe to require medical attention in its own right. Physical symptoms vary according to the substance being...
A cluster of psychotic phenomena that occur during or immediately after psychoactive substance use and are characterized by vivid hallucinations (typically auditory, but often in more than one sensory modality), misidentifications, delusions and/or ideas of reference (often of a paranoid or persecutory nature), psychomotor disturbances (excitement ...
A syndrome associated with chronic prominent impairment of recent memory; remote memory is sometimes impaired, while immediate recall is preserved. Disturbances of time sense and ordering of events are usually evident, as are difficulties in learning new material. Confabulation may be marked but is not invariably present. Other cognitive functions ...
Amnesic syndrome induced by alcohol or other psychoactive substances coded here should meet the general criteria for organic amnesic syndrome (see F04). The primary requirements for this diagnosis are: memory impairment as shown in impairment of recent memory (learning of new material); disturbances of time sense (rearrangements of chronological ...
A disorder in which alcohol- or psychoactive substance-induced changes of cognition, affect, personality, or behaviour persist beyond the period during which a direct psychoactive substance-related effect might reasonably be assumed to be operating.
May be distinguished from psychotic disorders partly by their episodic nature, frequently of very short duration (seconds or minutes) and by their duplication (sometimes exact) of previous drug-related experiences.
A glossary defining each category of mental disorder in ICD-8 was also developed. The programme activities also resulted in the establishment of a network of individuals and centres who
Most disorders in medicine are classified using the ICD (initiated in Paris in 1900). Mental and behavioural disorders are classified using the DSM (DSM-I was published in the USA in 1952), but it was not until DSM-III in 1980 that it became a major player.

Browse all the diagnosis codes used for mental and behavioural disorders (f01–f99). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range.
F99-F99 Unspecified mental disorder. This block comprises a range of mental disorders grouped together on the basis of their having in common a demonstrable etiology in cerebral disease, brain injury, or other insult leading to cerebral dysfunction.
