ICD-10 Code F65.9 – Paraphilia, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F65.9 – Paraphilia, unspecified
What it is
F65.9 identifies a paraphilia when the specific type is not documented. Use it for a persistent atypical sexual interest that does not fit a more specific coded diagnosis.
Clinical signs
Clinical features vary; refer to documentation. Records may describe recurrent atypical sexual urges, fantasies, or behaviors, with possible distress, impairment, or concern about risk to others.
When to use this code
Use F65.9 when the provider documents paraphilia but does not name the subtype. It is also appropriate when the chart notes an unspecified atypical sexual interest and no more specific diagnosis is available. Check documentation before coding.
Do not use for
Do not use this code if the record identifies a specific paraphilic disorder that has its own code. Do not assign it for ordinary sexual behavior or for concerns that are not diagnosed as paraphilia.
Coding tip
Query for the exact paraphilic disorder when the documentation is vague, because a more specific code may be available.
