Intermittent monocular exotropia, left eye

This code describes a condition where the left eye intermittently deviates outward (exotropia) while the other eye remains fixed on the target. This deviation is not constant and can be controlled by the patient at times.

Use this code when documentation specifies intermittent outward deviation of the left eye. This diagnosis is typically made during an ophthalmological examination, often supported by cover/uncover testing or observation of ocular alignment.

• Ensure laterality is clearly documented as "left eye" to support this specific code.
• Distinguish from constant exotropia (H50.1-) and intermittent exotropia of the right eye (H50.331) or bilateral (H50.333).
• Look for terms like "intermittent," "occasional," or "controlled exotropia" in the left eye.
