Disorders Due To Use Of MDMA Or Related Drugs – ICD 11 Codes

Definition of Disorders due to use of MDMA or related drugs including MDA: Disorders due to use of MDMA or related drugs, including MDA are characterised by the pattern and consequences of MDMA or related drug use. MDMA is methylene-dioxymethamphetamine and is a common drug of abuse in many countries especially among young people. It is predominantly available in tablet form known as ‘ecstasy’. Pharmacologically, MDMA has stimulant and empathogenic properties and these encourage its use among young people for social and other interactions. Considering its wide prevalence in many countries and among many sub-groups of young people, MDMA and Related Drug Dependence and MDMA and Related Drug Withdrawal are comparatively uncommon. Substance-Induced Mental Disorders may arise from its use. Several analogues of MDMA exist, including MDA (methylene-dioxyamphetamine).

6C4C.2 MDMA or related drug dependence including MDA

Definition of MDMA or related drug dependence including MDA: MDMA or related drug dependence, including MDA is a disorder of regulation of MDMA or related drug use arising from repeated or continuous use of MDMA or related drugs. The characteristic feature is a strong internal drive to use MDMA or related drugs, which is manifested by impaired ability to control use, increasing priority given to use over other activities and persistence of use despite harm or negative consequences. These experiences are often accompanied by a subjective sensation of urge or craving to use MDMA or related drugs. Physiological features of dependence may also be present, including tolerance to the effects of MDMA or related drugs, withdrawal symptoms following cessation or reduction in use of MDMA or related drugs, or repeated use of MDMA or pharmacologically similar substances to prevent or alleviate withdrawal symptoms. The features of dependence are usually evident over a period of at least 12 months but the diagnosis may be made if MDMA or related drug use is continuous (daily or almost daily) for at least 3 months.

6C4C.3 MDMA or related drug intoxication including MDA

Definition of MDMA or related drug intoxication including MDA: MDMA or related drug intoxication, including MDA is a clinically significant transient condition that develops during or shortly after the consumption of MDMA or related drugs that is characterised by disturbances in consciousness, cognition, perception, affect, behaviour, or coordination. These disturbances are caused by the known pharmacological effects of MDMA or related drugs and their intensity is closely related to the amount of MDMA or a related drug consumed. They are time-limited and abate as MDMA or a related drug is cleared from the body. Presenting features may include increased or inappropriate sexual interest and activity, anxiety, restlessness, agitation, and sweating. In rare instances, usually in severe intoxication, use of MDMA or related drugs, including MDA can result in dystonia and seizures. Sudden death is a rare but recognised complication.

The intensity or duration of the symptoms is substantially in excess of psychotic-like disturbances of perception, cognition, or behaviour that are characteristic of MDMA or related drug intoxication. The amount and duration of MDMA or related drug use must be capable of producing psychotic symptoms. The symptoms are not better explained by a primary mental disorder (e.g., Schizophrenia, a Mood disorder with psychotic symptoms), as might be the case if the psychotic symptoms preceded the onset of the MDMA or related drug use, if the symptoms persist for a substantial period of time after cessation of the MDMA or related drug use, or if there is other evidence of a pre-existing primary mental disorder with psychotic symptoms (e.g., a history of prior episodes not associated with MDMA or related drug use, including MDA).

The intensity or duration of the symptoms is substantially in excess of mood disturbances that are characteristic of MDMA or related drug intoxication, including MDA. The amount and duration of MDMA or related drug use must be capable of producing mood symptoms. The symptoms are not better explained by a primary mental disorder (e.g., a Depressive disorder, a Bipolar disorder, Schizoaffective disorder), as might be the case if the mood symptoms preceded the onset of the MDMA or related drug use, if the symptoms persist for a substantial period of time after cessation of the MDMA or related drug use, or if there is other evidence of a pre-existing primary mental disorder with mood symptoms (e.g., a history of prior episodes not associated with MDMA or related drug use).

Definition of MDMA or related drug-induced anxiety disorder: MDMA or related drug-induced anxiety disorder, including MDA is characterised by anxiety symptoms (e.g., apprehension or worry, fear, physiological symptoms of excessive autonomic arousal, avoidance behaviour) that develop during or soon after intoxication with MDMA or related drugs. The intensity or duration of the symptoms is substantially in excess of anxiety symptoms that are characteristic of MDMA or related drug intoxication, including MDA. The amount and duration of MDMA or related drug use must be capable of producing anxiety symptoms. The symptoms are not better explained by a primary mental disorder (e.g., an Anxiety and fear-related disorder, a Depressive disorder with prominent anxiety symptoms), as might be the case if the anxiety symptoms preceded the onset of the MDMA or related drug use, if the symptoms persist for a substantial period of time after cessation of the MDMA or related drug use, or if there is other evidence of a pre-existing primary mental disorder with anxiety symptoms (e.g., a history of prior episodes not associated with MDMA or related drug use).
