F98
Other behavioural and emotional disorders with onset usually
occurring in childhood and adolescence
A heterogeneous group of disorders that share the characteristic of an onset in
childhood but otherwise differ in many respects. Some of the conditions represent
well-defined syndromes but others are no more than symptom complexes that need
inclusion because of their frequency and association with psychosocial problems,
and because they cannot be incorporated into other syndromes.
Excludes: breath-holding spells ( R06.8 )
gender identity disorder of childhood ( F64.2 )
Kleine-Levin syndrome ( G47.8 )
obsessive-compulsive disorder ( F42.- )
sleep disorders due to emotional causes ( F51.- )
F98.0 Nonorganic enuresis
A disorder characterized by involuntary voiding of urine, by day and by night,
which is abnormal in relation to the individual's mental age, and which is not a
consequence of a lack of bladder control due to any neurological disorder, to
epileptic attacks, or to any structural abnormality of the urinary tract. The enuresis
may have been present from birth or it may have arisen following a period of
acquired bladder control. The enuresis may or may not be associated with a more
widespread emotional or behavioural disorder.
Enuresis (primary)(secondary) of nonorganic origin
Functional enuresis
Psychogenic enuresis
Urinary incontinence of nonorganic origin
Excludes: enuresis NOS ( R32 )
F98.1 Nonorganic encopresis
Repeated, voluntary or involuntary passage of faeces, usually of normal or nearnormal
consistency, in places not appropriate for that purpose in the individual's
own sociocultural setting. The condition may represent an abnormal continuation of
normal infantile incontinence, it may involve a loss of continence following the
acquisition of bowel control, or it may involve the deliberate deposition of faeces in
inappropriate places in spite of normal physiological bowel control. The condition
may occur as a monosymptomatic disorder, or it may form part of a wider disorder,
especially an emotional disorder (F93.-) or a conduct disorder (F91.-).
Functional encopresis
Incontinence of faeces of nonorganic origin
Psychogenic encopresis
Use additional code, if desired, to identify the cause of any coexisting constipation.
Excludes: encopresis NOS ( R15 )
F98.2 Feeding disorder of infancy and childhood
A feeding disorder of varying manifestations usually specific to infancy and early
childhood. It generally involves food refusal and extreme faddiness in the presence
of an adequate food supply, a reasonably competent caregiver, and the absence of
organic disease. There may or may not be associated rumination (repeated
regurgitation without nausea or gastrointestinal illness).
