Monocular esotropia with other noncomitancies, left eye

This code signifies a type of strabismus where the left eye deviates inward (esotropia) and the misalignment varies depending on the direction of gaze (noncomitant). This condition is specifically monocular, meaning only the left eye is affected by the esotropia.

Use this code when documentation clearly indicates a left monocular esotropia that is noncomitant. This typically occurs in cases of paralytic strabismus or restrictive ophthalmopathy affecting the left eye. Supporting documentation should detail the inward deviation of the left eye and its variability with eye movements.

• Ensure the documentation specifies "monocular" and "left eye" to differentiate from bilateral or right eye involvement.
• Verify that the esotropia is explicitly described as "noncomitant" or "incomitant" to distinguish it from comitant forms.
• Do not confuse with codes for intermittent esotropia or other forms of strabismus without the specified noncomitant characteristic.
