F66 — Psychological and behavioural disorders associated with sexual development and orientation

Concept, in one sentence

F66, as ICD-10 frames it, requires distress intrinsic to one's own orientation, not distress caused by discrimination or rejection — which often correctly resolves to 'not a disorder.'

Decisive boundary cues

• Distress genuinely intrinsic to uncertainty or discomfort about one's own orientation, orientation itself not in doubt for F66.1 -> as ICD-10 frames it, may meet this category's threshold.
• Distress clearly attributable to discrimination, rejection, or stigma -> does not meet this category's threshold; often correctly 'not a disorder.'
• Confusion or distress about gender identity rather than orientation -> see F64 instead.

Duration/course cue

Not specifically defined beyond the presence of the described distress or relationship difficulty.

Common mistake

Treating distress caused by discrimination or family rejection as evidence that a person's orientation itself needs addressing.
