Gender identity disorder of childhood

This code represents a persistent and intense distress in a child regarding their assigned sex at birth, accompanied by a strong desire to be of the opposite gender. This incongruence causes significant impairment in social, academic, or other important areas of functioning.

Apply this code when a pediatrician or mental health professional diagnoses a child (typically pre-pubertal) with gender dysphoria. Documentation should clearly indicate the child's age, the duration and intensity of gender incongruence, and the associated distress or functional impairment.

• Differentiate from F64.0; this code is specifically for childhood presentation, prior to adolescence.
• Do not code with F66 (sexual maturation disorder), as these are distinct conditions.
• Ensure documentation explicitly states "childhood" or provides the patient's age to support this specific diagnosis.
