ICD-10-CM F64: Gender Identity Disorders Overview

The ICD-10-CM F64 code group represents conditions related to gender incongruence and other gender identity diagnoses affecting psychological and social functioning. These diagnoses pertain to the mental and behavioral health domain and may influence treatment planning, mental health services, and gender-affirming care coordination. Accurate coding is important for complete clinical documentation and appropriate reimbursement for covered behavioral health and specialty services.

When to Use

Use a code from this group when clinical documentation indicates a diagnosed gender identity disorder or gender dysphoria that impacts care planning, mental health treatment, or services related to gender transition. Select the code that best matches the documented diagnosis, specificity, and any related clinical details such as childhood onset or unspecified status.

Typical Clinical Scenarios

A young adult assigned male at birth presents to a primary care clinic requesting referral for hormone therapy and documentation of persistent identification as female that began in adolescence; evaluation confirms a consistent, insistent, and persistent cross-gender identification without other psychotic or neurological disorders, and the clinician assigns a diagnosis to support gender-affirming care and record the gender incongruence. Typical codes: F64.0
An adolescent assigned female at birth is brought to an urgent behavioral health assessment after self-harm and severe distress related to incongruence between her experienced gender and her natal sex; the acute presentation requires safety planning and psychiatric stabilization, and a gender identity diagnosis is recorded as a contributing mental health condition. Typical codes: F64.1, F64.9
An adult with long-standing incongruence between experienced gender and natal sex seeks documentation of previous surgical and social transition history for legal and preoperative planning; the patient has no current acute psychiatric crisis but requires clear diagnostic coding to reflect ongoing gender-related identity concerns and prior treatments. Typical codes: F64.2, F64.9
