Monocular esotropia with V pattern, left eye

This code signifies a type of strabismus where the left eye is turned inward (esotropia) and the misalignment is more pronounced in upward gaze and less in downward gaze, forming a "V" pattern. This condition affects only the left eye, with the right eye maintaining proper alignment.

Use this code when documentation clearly indicates monocular esotropia of the left eye with a V pattern. This diagnosis is typically made during an ophthalmological examination, often involving prism cover tests and assessment of ocular motility in different gaze positions.

• Ensure the documentation specifies "monocular" and "left eye" to differentiate from bilateral or right eye involvement.
• Verify the presence of a "V pattern" as opposed to an "A pattern" or other types of incomitant strabismus.
• Do not confuse with H50.012 (Monocular esotropia, left eye) if the V pattern is not explicitly documented.
