Impulse disorders (F63) ICD-10-CM
The F63 code range covers impulse disorders with 9 ICD-10-CM diagnosis codes. 7 of them are billable and valid for claim submission in fiscal year 2027, and the category headers group them but cannot themselves be billed.
Type 2 Excludes
A type 2 excludes note represents "Not included here". An excludes2 note indicates that the condition excluded is not part of the condition represented by the code, but a patient may have both conditions at the same time. When an Excludes2 note appears under a code, it is acceptable to use both the code and the excluded code together, when appropriate.

Clinical Terms in This Code Range
Definitions from the National Library of Medicine for conditions coded in the F63 range.
Firesetting Behavior
A compulsion to set fires.
Intermittent Explosive Disorder
A disorder characterized by recurrent episodes of serious assaultive acts or destruction of property due to a failure to resist aggressive impulses; the degree of aggression during these episodes is grossly out of proportion to any psychosocial provocation. The aggressive episodes are not etiologically linked to another mental disorder, a general medical condition, or substance use.
Kleptomania
A disorder characterized by the recurrent failure to resist the impulse to steal items of little intrinsic value; the individual experiences a rising subjective sense of tension before the theft and a sense of gratification or relief during the theft.
Pathological Gambling
A disorder characterized by a preoccupation with gambling and the excitement that gambling with increasing risk provides. Pathological gamblers are unable to cut back on their gambling, despite the fact that it may lead them to lie, steal, or lose a significant relationship, job, or educational opportunity.
Trichotillomania
Compulsion to pull out one's hair.
