ICD-10 Code F64.2 – Gender identity disorder of childhood (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F64.2 – Gender identity disorder of childhood
What it is
F64.2 identifies a childhood pattern of persistent cross-gender identification and distress about assigned sex. Use it only when the documentation specifically supports this diagnosis.
Clinical signs
Clinical features may include a strong, persistent preference for the other gender, discomfort with one’s sex characteristics, and distress about gender role expectations. Clinical features vary; refer to documentation.
When to use this code
Use F64.2 when the provider documents gender identity disorder of childhood or equivalent wording in a child. It may also apply when the record clearly describes persistent gender-related distress or incongruence in childhood. Check documentation if the note is vague or uses only general gender concerns.
Do not use for
Do not use this code for transgender identity without a documented disorder, or for adult gender dysphoria. Do not assign it when the chart only mentions gender exploration or social transition.
Coding tip
Code F64.2 only from explicit provider documentation; if the diagnosis is unclear, query for clarification.
