Transsexualism

This diagnosis code signifies a persistent and profound incongruence between an individual's assigned sex at birth and their experienced gender identity. Individuals with this condition experience significant distress or impairment due to this discrepancy, often leading to a desire for medical and/or surgical transition to align their physical characteristics with their gender identity.

Use this code when documentation clearly indicates a diagnosis of transsexualism, characterized by a strong and persistent cross-gender identification and discomfort with one's assigned sex. Supporting documentation should include a psychiatric or psychological evaluation confirming the diagnosis based on established diagnostic criteria.

• Do not confuse with F64.2 (gender identity disorder of childhood), as these conditions are mutually exclusive.
• Ensure documentation specifies adult presentation of gender incongruence.
• Consider sequencing with codes for related mental health conditions or physical health issues arising from gender dysphoria or transition.
