Code Description

ICD-10 R46.81 is a billable code used to indicate a diagnosis of obsessive-compulsive behavior.

Key Diagnostic Point:

Obsessive-compulsive behavior (OCB) is characterized by persistent, unwanted thoughts (obsessions) and repetitive behaviors or mental acts (compulsions) that an individual feels driven to perform in response to the obsessions. These behaviors are often aimed at reducing anxiety or preventing a feared event or situation, but they are not connected in a realistic way to the feared event. Symptoms may include excessive hand washing, checking, counting, or organizing. Patients may recognize that their thoughts and behaviors are excessive or unreasonable, yet they feel unable to control them. OCB can significantly impair daily functioning and quality of life, leading to distress and avoidance of situations that trigger symptoms. It is important to differentiate OCB from other anxiety disorders and to assess the severity and impact on the patient's life. Clinical evaluation often involves structured interviews and standardized assessment tools to gauge the frequency and intensity of symptoms.
