Impulse disorders (F63)
The ICD-10 code section F63 covers impulse disorders, conditions characterized by difficulty resisting urges that can lead to harmful behaviors. These codes are specifically used to classify various impulse control issues such as pathological gambling, pyromania, kleptomania, and trichotillomania.
This section includes codes like F63.0 for pathological gambling; also known as compulsive gambling or gambling disorder whether offline or online. F63.1 identifies pyromania, which involves repeated firesetting or destructive behavior toward property. F63.2 is for kleptomania, the uncontrollable urge to steal, and F63.3 covers trichotillomania, habitual hair-pulling. Other impulse disorders are grouped under F63.8 and its subcodes, including intermittent explosive disorder (F63.81) marked by sudden aggressive outbursts. The code F63.89 captures less common behaviors such as compulsive knuckle-biting or gaming disorder. When the specific impulse disorder is unclear, F63.9 is used as an unspecified category. These codes help medical professionals and coders pinpoint and document distinct impulse control problems accurately, facilitating better diagnosis and treatment planning.
