Oppositional defiant disorder

This diagnosis code represents a behavioral disorder in children and adolescents characterized by a persistent pattern of angry/irritable mood, argumentative/defiant behavior, or vindictiveness. These behaviors are beyond the normal range for the individual's age and developmental level, and they cause significant impairment in social, academic, or occupational functioning. It is distinct from conduct disorder, though it can sometimes precede it.

Use this code when documentation clearly indicates a diagnosis of oppositional defiant disorder based on established diagnostic criteria (e.g., DSM-5). This applies to patients exhibiting a consistent pattern of negativistic, hostile, and defiant behavior towards authority figures for at least six months. Supporting documentation should detail the specific symptoms, their duration, and the resulting functional impairment.

• Differentiate carefully from Conduct Disorder (F91.1, F91.2), as ODD does not involve aggression towards people/animals, destruction of property, or theft/deceit.
• Ensure the documentation specifies the duration and severity of symptoms to support the diagnosis.
• This code is typically a primary diagnosis for mental health encounters but may be secondary if another condition is the focus of the visit.
