2025 ICD-10-CM code F84.3
(Active) Effective Date: N/A Revision Date: N/A Deletion Date: N/A Neurodevelopmental disorders - Pervasive and specific developmental disorders Chapter V: Mental, Behavioral and Neurodevelopmental disorders (F00-F99) Feed
Other childhood disintegrative disorder; a rare neurodevelopmental disorder involving the loss of previously acquired skills in various areas.
Medical necessity is established through clinical evaluation demonstrating significant regression in multiple developmental areas, impacting the child's ability to function in daily life.Treatment interventions aimed at improving communication, social skills, adaptive behavior, and reducing disruptive behaviors are medically necessary to mitigate functional limitations.
Diagnosis is based on clinical evaluation, history, and comparison to diagnostic criteria. Management often involves a multidisciplinary approach including occupational therapy, speech therapy, and behavioral interventions.The cause is unknown, requiring a focus on managing symptoms and supporting the child's development.

- F84.3 falls under the broader category of pervasive developmental disorders (F84).
In simple words: This code describes a rare condition where a child loses skills they once had, like talking, playing with others, or moving normally. This happens after a period of normal development, usually before age 10. The child may lose these skills gradually or suddenly.Doctors use this code to describe this type of problem, which is different from autism or other similar disorders.
F84.3, Other childhood disintegrative disorder, is a rare neurodevelopmental disorder characterized by a significant loss of previously acquired skills across multiple domains.This typically manifests after a period of seemingly normal development, usually before the age of 10.Affected individuals experience regression in language, social interaction, motor skills, and adaptive behavior.The onset can be gradual or abrupt, often occurring over a period of six to nine months.Additional codes should be used to specify any co-occurring neurological conditions.Synonyms include dementia infantilis, disintegrative psychosis, Heller syndrome, and symbiotic psychosis.
Example 1: A 5-year-old child who previously had normal language development begins to lose speech skills, exhibits decreased social interaction, and shows regression in fine motor skills.The child's development plateaued at age 2 and experienced regression after that., An 8-year-old child with previously typical development experiences a sudden decline in social skills, adaptive behavior, and communication abilities. This regression is notable after a period of seemingly normal development, beginning at age 7., A 9-year-old child presents with a gradual loss of previously acquired language, motor and social skills, accompanied by repetitive behaviors. This regression began subtly at age 6, gradually worsening over several years.
Detailed developmental history, including milestones achieved and skills lost; comprehensive neurological examination; standardized assessments of language, social interaction, and adaptive behavior; documentation of behavioral observations; and any coexisting medical conditions.
** This is a rare disorder, and accurate diagnosis often requires a multidisciplinary approach involving specialists in neurology, psychiatry and developmental pediatrics.Careful differentiation from other pervasive developmental disorders is crucial.
