ICD-10 Code F65.81 – Frotteurism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F65.81 – Frotteurism
What it is
Frotteurism is a sexual disorder involving recurrent, intense arousal from touching or rubbing against a nonconsenting person. Use this code when the behavior is documented as the diagnosis.
Clinical signs
Clinical features include repeated urges, fantasies, or acts involving nonconsensual rubbing or touching. Documentation may note distress, impairment, or legal involvement; clinical features vary, so refer to documentation.
When to use this code
Use F65.81 when the record clearly identifies frotteurism as the reason for the encounter or as an established diagnosis. It may appear in psychiatric, behavioral health, or forensic documentation. Code only what is explicitly documented.
Do not use for
Do not use this code for consensual sexual behavior, general sexual dysfunction, or unspecified inappropriate touching without a documented diagnosis. Check documentation if the record does not clearly support frotteurism.
Coding tip
Confirm the diagnosis is stated by the clinician; do not infer frotteurism from behavior alone.
