Exophoria

This code represents a form of strabismus where one eye deviates outward when binocular fusion is disrupted, but the eyes are aligned when both are open and focusing. It is a latent deviation, meaning it is not always apparent and often only becomes manifest under specific testing conditions.

Use this code when documentation explicitly states "exophoria" as the patient's diagnosis. This condition is typically identified during an ophthalmological examination through cover/uncover tests or other specific strabismus evaluations.

• Differentiate from exotropia (H50.1-), which is a manifest outward deviation.
• Laterality is not specified for exophoria; use this code regardless of whether it affects one or both eyes.
• Ensure the documentation clearly distinguishes between latent (phoria) and manifest (tropia) deviations.
