What are the ICD‑11 criteria (code HA60) for diagnosing Gender Incongruence in adolescents and adults?

ICD-11 Gender Incongruence Criteria (Code HA60)

Gender Incongruence in ICD-11 is characterized by a marked and persistent incongruence between an individual's experienced gender and the assigned sex, which often leads to a desire to transition, in order to live and be accepted as a person of the experienced gender. 1

Core Diagnostic Features

The ICD-11 represents a fundamental shift from previous classifications by moving Gender Incongruence out of the mental disorders chapter into a new chapter on "Conditions Related to Sexual Health." 2, 3 This reflects the current understanding that gender diversity is not a mental illness but rather a health condition requiring medical support.

Key Diagnostic Elements

For adolescents and adults (HA60), the diagnosis requires:

• Marked incongruence between experienced/expressed gender and assigned sex
• Persistent pattern - the incongruence must be present for several months (though the exact duration remains debated in clinical practice) 4
• Desire to transition - typically includes wanting to live and be accepted as a person of the experienced gender
• May involve desire for medical interventions (hormones, surgery) to align physical characteristics with experienced gender

Critical Distinction from Previous Classifications

The distress criterion has been removed. 5 Unlike ICD-10's "Transsexualism" or DSM-5's "Gender Dysphoria," ICD-11 does not require psychological distress for diagnosis. This is crucial because:

• Gender incongruence itself is the condition, not the distress it may cause
• Distress (gender dysphoria) is not universally present in transgender individuals 1
• Access to gender-affirming care should not depend on demonstrating suffering

What ICD-11 Does NOT Require

• No minimum 2-year duration (unlike ICD-10 Transsexualism criteria) 6
• No requirement for clinically significant distress or functional impairment
• No exclusion for intersex conditions (this has been removed)
• No specification of sexual orientation (completely eliminated from classification)

Clinical Application

The diagnosis should be straightforward when an individual presents with:

1. Clear statement of gender identity differing from assigned sex
2. Consistent pattern over time (several months minimum)
3. Desire for social and/or medical transition

Common pitfall: Do not conflate gender expression with gender identity. An individual may have gender incongruence without conforming to stereotypical gender expressions. 7

Important consideration: The ICD-11 criteria are intentionally less restrictive than previous versions to reduce barriers to care while maintaining diagnostic validity. 4, 5 Studies show interrater reliability of 65-79% for adolescent/adult diagnoses, comparable to or better than previous classification systems.

Practical Implications

The reclassification aims to:

• Reduce stigma associated with psychiatric diagnosis
• Maintain access to healthcare and insurance coverage
• Facilitate gender-affirming treatments that improve quality of life and reduce depression and suicidality 1

Healthcare providers should use this diagnosis to enable access to gender-affirming care, not as a gatekeeping mechanism. The focus is on supporting the individual's gender identity journey rather than pathologizing their experience. 8, 3
