F83

F83 is an ICD-10-CM diagnostic code used to denote mixed disorders of conduct and emotions. It is applied in pediatric and adolescent psychiatry when a clinician identifies a combination of behavioral problems and emotional disturbances that are not better explained by a single, more specific disorder.

Clinical features typically involve both conduct-related issues and emotional symptoms. Children and adolescents assigned F83 may exhibit rule-breaking behavior, aggression, or difficulties with social norms alongside anxiety, mood fluctuations, or sadness. The presentation can be heterogeneous and is often identified through clinical interviews, observations, and information from caregivers and teachers. There are no laboratory tests that define F83; diagnosis relies on clinical judgment and the exclusion of other distinct conditions.

Differential diagnosis includes ADHD, oppositional defiant disorder, conduct disorder, mood and anxiety disorders, learning or communication disorders, and autism spectrum disorder. Clinicians assess whether symptoms reflect a primary disorder or a true mix of problems across multiple domains. Comorbidity is common, which can complicate treatment planning.

Treatment for mixed disorders of conduct and emotions is typically multimodal. Psychosocial interventions such as cognitive-behavioral therapy, parent management training, and family therapy are common components, often complemented by educational supports. Pharmacotherapy may be considered to address specific comorbid symptoms (for example, mood symptoms or attention difficulties) when clinically indicated, rather than as a treatment for F83 itself.

Prognosis varies with the severity and persistence of symptoms, early intervention, and ongoing support. The code is primarily used for documentation, billing, and statistical purposes within health care systems.
