Documentation considerations

Diagnostic evaluation for intermittent exotropia relies on detailed clinical assessment using both objective and subjective methods to support accurate recognition and individualized treatment strategies. 2

Clinical documentation for intermittent exotropia may reflect a dynamic disease course ranging from intermittent episodes with preserved fusion to progression toward constant exotropia with associated sensory adaptations. 2

What the sources add

While the terminology record establishes the official code definition and hierarchy for H50.112, the clinical literature provides operational context regarding the dynamic progression and evidence-based management of intermittent exotropia. 1 2

The clinical reference indicates that in adults, intermittent exotropia may represent decompensation of a previously controlled exophoria or, less commonly, a sequela of trauma or neurologic disease. 2
