Code Description

ICD-10 F65.9 is a billable code used to indicate a diagnosis of paraphilia, unspecified.

Key Diagnostic Point:

Paraphilia, unspecified, refers to a condition characterized by atypical sexual interests that may cause distress or impairment in social, occupational, or other important areas of functioning. This diagnosis is used when the specific type of paraphilia is not clearly defined or when the clinician chooses not to specify the nature of the paraphilia. Paraphilias can include a wide range of behaviors, such as fetishism, exhibitionism, voyeurism, and sadomasochism, among others. The condition is often associated with maladaptive behaviors that may lead to legal issues or interpersonal conflicts. Individuals with paraphilias may struggle with impulse control and may exhibit personality disorders, particularly if their behaviors lead to significant distress or dysfunction. The diagnosis of unspecified paraphilia is often a preliminary step in treatment, allowing for further assessment and clarification of the individual's specific interests and behaviors. Clinicians must carefully evaluate the impact of these behaviors on the individual's life and consider co-occurring mental health issues, such as anxiety or depression, which may complicate the clinical picture.

  • Potential overlap with personality disorders and impulse control issues
  • Subjectivity in determining distress or impairment caused by behaviors

Audit Risk Factors

  • Inadequate documentation of the patient's history and behaviors
  • Failure to specify the nature of the paraphilia when possible
  • Lack of evidence for distress or impairment in functioning
  • Inconsistent coding practices among providers
