ICD-11 represents major shift in the classification of gender identity-related health

The World Health Organization’s International classification of diseases 11th revision (ICD-11) came into effect in February 2022 and includes significant updates to the classification of gender identity-related health compared with ICD 10th revision (ICD-10).

These include:

  • Gender identity disorder" and "transsexualism" have been replaced with "gender incongruence".

  • New diagnostic categories have been moved out of the "Mental and behavioral disorders" chapter and into the new "Conditions related to sexual health" chapter.

Minor changes have also been made to terminology used in the Diagnostic and Statistical Manual of Mental Disorders, 5th Edition, Text Revision (DSM-5-TR), published in March 2022.

These include:

  • Use of "experienced gender" rather than "desired gender".

  • Use of "gender-affirming" rather than "cross-sex" in relation to treatment and medical procedures.

It is hoped that the updates to language used in ICD-11 and DSM-5-TR will help remove stigma associated with gender diversity.
