Code Description

ICD-10 F66 is a billable code used to indicate a diagnosis of other sexual disorders.

Key Diagnostic Point:

F66 encompasses a range of sexual disorders that do not fit neatly into other specific categories. This includes disorders related to sexual identity, impulse control, and maladaptive behaviors that affect sexual functioning and relationships. Individuals may experience difficulties stemming from personality disorders, such as borderline or narcissistic traits, which can complicate their sexual relationships. Impulse control disorders may manifest as compulsive sexual behavior or paraphilias, leading to distress or impairment in social, occupational, or other important areas of functioning. Gender identity issues, including gender dysphoria, may also fall under this category, where individuals experience significant discomfort with their assigned gender at birth, impacting their sexual health and relationships. The complexity of these disorders often requires a nuanced understanding of the interplay between psychological, social, and biological factors, making diagnosis and treatment challenging. Clinicians must consider the individual's history, presenting symptoms, and the impact of these disorders on their overall well-being.
