About F63.8

F63.8 is the ICD-10-CM diagnosis code for other impulse disorders. It belongs to category F63 (impulse disorders), block F60-F69 (disorders of adult personality and behavior) and chapter 5 (mental, Behavioral and Neurodevelopmental disorders). It is a header code, so it can't be reported by itself; one of its 2 subcodes must be used instead.

Within F63, choose F63.8 (Other impulse disorders) only when documentation doesn't support a more specific option: pathological gambling (F63.0), Pyromania (F63.1), Kleptomania (F63.2), Trichotillomania (F63.3) and impulse disorder, unspecified (F63.9).

To report this condition, pick the subcode that matches the documentation: F63.81 (disorder) and F63.89 (disorders).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
