About the F90–F98 Code Range
ICD-10 codes F90-F98 cover a range of behavioral and emotional disorders that usually start in childhood or adolescence. These codes include conditions such as attention-deficit hyperactivity disorder (ADHD), conduct disorders, emotional disorders, disorders of social functioning, tic disorders, and other specified behavioral issues.
This range provides detailed coding options for various childhood and adolescent disorders. For example, F90 codes specify types of ADHD, including predominantly inattentive (inattentive presentation), predominantly hyperactive, combined types, and unspecified forms. The F91 series encompasses conduct disorders, including those confined to family context, childhood- or adolescent-onset, oppositional defiant disorder, and unspecified conduct issues. Emotional disorders specific to childhood, like separation anxiety (F93.0), and social functioning disorders such as selective mutism (F94.0) and reactive attachment disorders (F94.1-F94.2) are included. Tic disorders are captured under F95, with distinctions between transient tics, chronic tic disorders, and Tourette’s disorder. Lastly, F98 codes address other behavioral or emotional disorders such as enuresis (bedwetting), encopresis, feeding disorders, pica, stereotyped movements, and adult onset fluency disorder. The synonyms provided clarify terms often used interchangeably, guiding coders and clinicians toward precise diagnosis coding for accurate health records and treatment planning.
