Disruptive mood dysregulation disorder

This code represents a chronic, severe irritability in children and adolescents characterized by persistent negative mood between episodes of severe temper outbursts. These outbursts are disproportionate to the situation and occur frequently, typically three or more times per week, for at least 12 months. The mood between outbursts is persistently irritable or angry most of the day, nearly every day.

Use this code for patients aged 6-18 years who meet the diagnostic criteria for Disruptive Mood Dysregulation Disorder (DMDD) as outlined in the DSM-5. Documentation should clearly describe the frequency and severity of temper outbursts, the persistent irritable or angry mood between outbursts, and the duration of these symptoms. This diagnosis is typically made by a psychiatrist or other qualified mental health professional.

• Ensure the patient's age is within the 6-18 year range for this diagnosis.
• Do not code this in conjunction with Bipolar Disorder, as DMDD is considered a distinct diagnosis.
• Differentiate from Oppositional Defiant Disorder (ODD) by the severity and pervasiveness of the irritability and anger, which are more pronounced in DMDD.
