ICD-10 Code F64.1 – Dual role transvestism (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F64.1 – Dual role transvestism
What it is
F64.1 identifies dual role transvestism, a condition where a person wears clothing associated with the opposite sex for emotional comfort or identity expression. It is not the same as gender dysphoria; check documentation.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the record describes recurrent cross-dressing without evidence of sexual arousal as the primary purpose, and without a persistent desire for surgical sex reassignment.
When to use this code
Use F64.1 when the clinician documents dual role transvestism or an equivalent diagnosis. Code it when the note clearly distinguishes this condition from fetishistic transvestism, gender incongruence, or other gender-related diagnoses. If the wording is unclear, check documentation.
Do not use for
Do not use this code for cross-dressing done mainly for sexual excitement, or for gender dysphoria/gender incongruence. Avoid it when the chart only mentions dressing in another gender’s clothing without a documented diagnosis.
Coding tip
Assign F64.1 only when the provider explicitly documents dual role transvestism; otherwise, query for clarification.
