Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the F84 range.
Asperger Syndrome
A disorder beginning in childhood whose essential features are persistent impairment in reciprocal social communication and social interaction, and restricted, repetitive patterns of behavior, interests, or activities. These symptoms may limit or impair everyday functioning. (From DSM-5)
Autism Spectrum Disorder
A spectrum of developmental disorders that includes autism, Asperger syndrome, and Rett syndrome. Signs and symptoms include poor communication skills, defective social interactions, and repetitive behaviors.
Autistic Disorder
A disorder beginning in childhood. It is marked by the presence of markedly abnormal or impaired development in social interaction and communication and a markedly restricted repertoire of activity and interest. Manifestations of the disorder vary greatly depending on the developmental level and chronological age of the individual. (DSM-V)
Pervasive Developmental Disorder
A category of developmental disorders characterized by impaired communication and socialization skills. The impairments are incongruent with the individual's developmental level or mental age. These disorders can be associated with general medical or genetic conditions.
Rett Syndrome
An inherited neurological developmental disorder that is associated with X-LINKED INHERITANCE and may be lethal in utero to hemizygous males. The affected female is normal until the age of 6-25 months when progressive loss of voluntary control of hand movements and communication skills; ATAXIA; SEIZURES; autistic behavior; intermittent HYPERVENTILATION; and HYPERAMMONEMIA appear. (From Menkes, Textbook of Child Neurology, 5th ed, p199)
About the F84 Code Range
These developmental disorders include autism, Asperger syndrome, Rett syndrome, and childhood disintegrative disorder. Autism spectrum disorder includes the first three and can involve communication and social difficulties and repetitive behaviors.
The subdivisions distinguish autistic disorder (F84.0), Rett's syndrome (F84.2), other childhood disintegrative disorder (F84.3), and Asperger's syndrome (F84.5). Separate subdivisions identify other pervasive developmental disorders (F84.8) and an unspecified pervasive developmental disorder (F84.9).
