Obsessive Compulsive Or Related Disorders – ICD 11 Codes

Definition of Obsessive-Compulsive Or Related Disorders: Obsessive-compulsive and related disorders is a group of disorders characterised by repetitive thoughts and behaviours that are believed to share similarities in aetiology and key diagnostic validators. Cognitive phenomena such as obsessions, intrusive thoughts and preoccupations are central to a subset of these conditions (i.e., obsessive-compulsive disorder, body dysmorphic disorder, hypochondriasis, and olfactory reference disorder) and are accompanied by related repetitive behaviours. Hoarding Disorder is not associated with intrusive unwanted thoughts but rather is characterised by a compulsive need to accumulate possessions and distress related to discarding them. Also included in the grouping are body-focused repetitive behaviour disorders, which are primarily characterised by recurrent and habitual actions directed at the integument (e.g., hair-pulling, skin-picking) and lack a prominent cognitive aspect. The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational, or other important areas of functioning.

Obsessive-Compulsive Disorder

Definition of Obsessive-Compulsive Disorder: Obsessive-Compulsive Disorder is characterised by the presence of persistent obsessions or compulsions, or most commonly both. Obsessions are repetitive and persistent thoughts, images, or impulses/urges that are intrusive, unwanted, and are commonly associated with anxiety. The individual attempts to ignore or suppress obsessions or to neutralize them by performing compulsions. Compulsions are repetitive behaviours including repetitive mental acts that the individual feels driven to perform in response to an obsession, according to rigid rules, or to achieve a sense of ‘completeness’. In order for obsessive-compulsive disorder to be diagnosed, obsessions and compulsions must be time consuming (e.g. taking more than an hour per day) or result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

6B20.0 Obsessive-compulsive disorder with fair to good insight

Definition of Obsessive-compulsive disorder with fair to good insight: All definitional requirements of obsessive-compulsive disorder are met. Much of the time, the individual is able to entertain the possibility that his or her disorder-specific beliefs may not be true and is willing to accept an alternative explanation for his or her experience. At circumscribed times (e.g., when highly anxious), the individual may demonstrate no insight.

6B20.1 Obsessive-compulsive disorder with poor to absent insight

Definition of Obsessive-compulsive disorder with poor to absent insight: All definitional requirements of obsessive-compulsive disorder are met. Most or all of the time, the individual is convinced that the disorder-specific beliefs are true and cannot accept an alternative explanation for their experience. The lack of insight exhibited by the individual does not vary markedly as a function of anxiety level.

6B20.Z Obsessive-compulsive disorder unspecified

Body dysmorphic disorder

Definition of Body dysmorphic disorder: Body Dysmorphic Disorder is characterised by persistent preoccupation with one or more perceived defects or flaws in appearance that are either unnoticeable or only slightly noticeable to others. Individuals experience excessive self-consciousness, often with ideas of reference (i.e., the conviction that people are taking notice, judging, or talking about the perceived defect or flaw). In response to their preoccupation, individuals engage in repetitive and excessive behaviours that include repeated examination of the appearance or severity of the perceived defect or flaw, excessive attempts to camouflage or alter the perceived defect, or marked avoidance of social situations or triggers that increase distress about the perceived defect or flaw. The symptoms are sufficiently severe to result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

Olfactory reference disorder

Definition of Olfactory reference disorder: Olfactory Reference Disorder is characterised by persistent preoccupation with the belief that one is emitting a perceived foul or offensive body odour or breath that is either unnoticeable or only slightly noticeable to others. Individuals experience excessive self-consciousness about the perceived odour, often with ideas of reference (i.e., the conviction that people are taking notice, judging, or talking about the odour). In response to their preoccupation, individuals engage in repetitive and excessive behaviours such as repeatedly checking for body odour or checking the perceived source of the smell, or repeatedly seeking reassurance, excessive attempts to camouflage, alter, or prevent the perceived odour, or marked avoidance of social situations or triggers that increase distress about the perceived foul or offensive odour. The symptoms are sufficiently severe to result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

Hypochondriasis

Definition of Hypochondriasis: Hypochondriasis is characterised by persistent preoccupation or fear about the possibility of having one or more serious, progressive or life-threatening illnesses. The preoccupation is accompanied by either: 1) repetitive and excessive health-related behaviours, such as repeatedly checking of the body for evidence of illness, spending inordinate amounts of time searching for information about the feared illness, repeatedly seeking reassurance (e.g. arranging multiple medical consultations); or 2) maladaptive avoidance behaviour related to health (e.g. avoids medical appointments). The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

Hoarding disorder

Definition of Hoarding disorder: Hoarding disorder is characterised by accumulation of possessions that results in living spaces becoming cluttered to the point that their use or safety is compromised. Accumulation occurs due to both repetitive urges or behaviours related to amassing items and difficulty discarding possessions due to a perceived need to save items and distress associated with discarding them. If living areas are uncluttered this is only due to the intervention of third parties (e.g., family members, cleaners, authorities). Amassment may be passive (e.g. accumulation of incoming flyers or mail) or active (e.g. excessive acquisition of free, purchased, or stolen items). The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.

  6B24  Hoarding disorder

6B24.0 Hoarding disorder with fair to good insight

Definition of Hoarding disorder with fair to good insight: All definitional requirements of hoarding disorder are met. The individual recognizes that hoarding-related beliefs and behaviours (pertaining to excessive acquisition, difficulty discarding, or clutter) are problematic. This qualifier level may still be applied if, at circumscribed times (e.g., when being forced to discard items), the individual demonstrates no insight.

Body-focused repetitive behaviour disorders

Definition of Body-focused repetitive behaviour disorders: Body focused repetitive behaviour disorders are characterised by recurrent and habitual actions directed at the integument (e.g. hair-pulling, skin-picking, lip-biting), typically accompanied by unsuccessful attempts to decrease or stop the behaviour involved, and which lead to dermatological sequelae (e.g., hair loss, skin lesions, lip abrasions). The behaviour may occur in brief episodes scattered throughout the day or in less frequent but more sustained periods. The symptoms result in significant distress or significant impairment in personal, family, social, educational, occupational or other important areas of functioning.
