Monocular esotropia with V pattern, right eye

This code describes a type of strabismus where the right eye deviates inward (esotropia) when both eyes are open, and the deviation significantly increases on upward gaze and decreases on downward gaze, forming a "V" pattern. This condition indicates a vertical incomitance associated with the horizontal deviation.

Apply this code when documentation clearly specifies monocular esotropia of the right eye with a V pattern. This is typically diagnosed during an ophthalmological examination, often involving prism cover testing in different gaze positions. Supporting documentation should detail the specific eye affected and the presence of the V pattern.

• Ensure the documentation specifies "monocular" involvement and the "right eye" to differentiate from bilateral or left eye involvement.
• Confirm the presence of a "V pattern" as opposed to an "A pattern" or other incomitant strabismus types.
• Do not confuse with codes for intermittent esotropia or other forms of concomitant strabismus.
