Intermittent monocular esotropia, left eye

This code describes a type of strabismus where the left eye intermittently turns inward (esotropia) while the right eye maintains proper alignment. This inward turning is not constant but occurs periodically, leading to misaligned vision in the affected eye.

Use this code when documentation clearly indicates intermittent esotropia specifically affecting the left eye. This diagnosis is typically made during an ophthalmological examination, often supported by findings from cover/uncover tests or prism measurements.

• Ensure the documentation specifies "intermittent" and "monocular" for the left eye.
• Distinguish from constant esotropia (H50.0-) or alternating esotropia (H50.32-).
• Laterality is crucial; do not use for right eye (H50.311) or bilateral (H50.313) involvement.
