About F63

F63 is the ICD-10-CM diagnosis code for impulse disorders. It belongs to 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 6 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: F63.0 (gambling), F63.1 (Pyromania), F63.2 (Kleptomania), F63.3 (Trichotillomania), F63.8 (disorders) and F63.9 (unspecified).

The conditions in its Excludes2 note aren't part of F63, but may be coded alongside it if the patient has both: habitual excessive use of alcohol or psychoactive substances (F10-F19) and impulse disorders involving sexual behavior (F65.-).

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