Monocular exotropia, left eye

This code signifies a divergent strabismus affecting only the left eye, where the eye turns outward. This misalignment prevents the eyes from focusing on the same point simultaneously, leading to potential visual disturbances.

Apply this code when documentation explicitly states monocular exotropia of the left eye. This diagnosis is typically made during an ophthalmological examination, often noted as "left exotropia" or "exotropia OS."

• Differentiate from intermittent exotropia (H50.13-) or other forms of strabismus.
• Ensure laterality is clearly documented as "left eye" (OS).
• Do not use if the exotropia affects both eyes or is unspecified.
