Impulsiveness

Code Description

ICD-10 R45.87 is a billable code used to indicate a diagnosis of impulsiveness.

Key Diagnostic Point:

Impulsiveness is characterized by a tendency to act on whims without considering the consequences, often leading to risky behaviors or decisions. This symptom can manifest in various ways, including sudden urges to engage in activities such as spending sprees, substance use, or reckless driving. Impulsiveness may be observed in various psychiatric conditions, including attention-deficit/hyperactivity disorder (ADHD), borderline personality disorder, and certain mood disorders. Clinically, it can present as difficulty in delaying gratification, a lack of foresight, and an inability to control urges. The underlying mechanisms may involve dysregulation of neurotransmitters such as dopamine and serotonin, which play crucial roles in reward processing and impulse control. Assessment typically involves a thorough clinical interview, standardized questionnaires, and possibly neuropsychological testing to evaluate the extent and impact of impulsive behaviors on daily functioning.
