ICD-10-CM Code for Intermittent Explosive Disorder
The ICD-10-CM code for Intermittent Explosive Disorder (IED) is F63.81.
Key Coding Information
Intermittent Explosive Disorder is classified under the Mental, Behavioural or Neurodevelopmental Disorders chapter and is characterized by repeated brief episodes of verbal or physical aggression or destruction of property representing a failure to control aggressive impulses 1.
Important Context About IED Classification
- IED is a relatively new diagnostic category that was formally added to ICD-11 as a distinct disorder 1
- In ICD-10-CM (the U.S. clinical modification currently in use), IED is coded as F63.81 under "Other impulse disorders"
- The disorder is notably underdiagnosed, with only 0.03% of patients receiving this diagnosis despite an actual lifetime prevalence of approximately 5.1% 2, 3
Clinical Recognition
When documenting IED for coding purposes, ensure the medical record clearly describes:
- Recurrent episodes of impulsive aggression
- Disproportionate outbursts relative to provocation
- Failure to control aggressive impulses
- Episodes involving verbal aggression, physical aggression, or property destruction
Common Coding Pitfall
Be aware that IED has extensive psychiatric comorbidities - 95.7% of individuals with IED have another psychiatric diagnosis 2. Medical coders may inadvertently use only the comorbid condition codes (such as mood disorders, anxiety disorders, or substance use disorders) and miss the IED diagnosis entirely. Ensure documentation specifically mentions the episodic, impulsive nature of aggressive outbursts to facilitate accurate F63.81 coding.
