0.000What This Code Means
A condition marked by recurrent episodes of aggressive outbursts that are disproportionate to the triggering stressor, with inability to control anger.
Coding Tips
- •Differentiate from aggression secondary to other conditions like bipolar disorder, ADHD, or substance use
- •Document specific episodes showing loss of control and disproportionate response
Clinical Significance
Intermittent explosive disorder (IED) is characterized by recurrent behavioral outbursts representing a failure to control aggressive impulses, manifesting as verbal aggression or physical aggression toward property, animals, or people. The aggression is grossly disproportionate to the provocation. IED is associated with increased emergency department utilization, legal problems, and comorbid depression, anxiety, and substance use disorders.
Documentation Requirements
- ✓Provider documentation of recurrent behavioral outbursts with failure to control aggressive impulses
- ✓Evidence that aggressive outbursts are grossly out of proportion to the provocation or stressor
- ✓Documentation that episodes are not premeditated and are not committed to achieve a tangible objective
- ✓Exclusion of aggression better explained by another mental disorder (bipolar mania, conduct disorder, antisocial PD, psychosis, substance intoxication)
- ✓Minimum age of 6 years; assessment of chronicity (recurrent episodes over at least 3 months)
