Intermittent monocular esotropia, right eye

This code describes a form of strabismus where the right eye intermittently turns inward (esotropia) while the left eye maintains fixation. This inward deviation is not constant but occurs at various times, impacting binocular vision.

Apply this code when documentation clearly indicates an intermittent esotropia affecting only the right eye. This diagnosis is typically made during an ophthalmological examination, often noting the deviation during specific tasks or states of fatigue.

• Differentiate from constant esotropia (H50.0-) and intermittent esotropia of the left eye (H50.312) or bilateral involvement (H50.32).
• Ensure the laterality (right eye) is explicitly documented to support this specific code.
• Consider additional codes for associated conditions such as amblyopia if present.
