309.3
ICD-9-CMThis diagnosis code signifies an emotional or behavioral reaction to an identifiable psychosocial stressor that develops within three months of the stressor's onset. The disturbance is characterized by a pattern of behavior that violates the rights of others or major age-appropriate societal norms and rules. This reaction is clinically significant, causing marked distress or significant impairment in social or occupational functioning.
Apply this code when a patient presents with maladaptive behavioral symptoms, such as truancy, vandalism, fighting, or defiance, directly following a stressful life event (e.g., parental divorce, school problems, relocation). Documentation should clearly link the onset of these conduct disturbances to a specific stressor and indicate that the symptoms are not merely an exacerbation of a pre-existing mental disorder.
