Monocular exotropia with V pattern, left eye

This code signifies a specific type of strabismus where the left eye deviates outward (exotropia) and the deviation is more pronounced in upgaze compared to downgaze, forming a "V" shape. This condition is a form of incomitant strabismus affecting only one eye.

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

• Ensure the documentation specifies "monocular" and "left eye" to differentiate from binocular or right eye involvement.
• Verify the presence of a "V pattern" as opposed to an "A pattern" or other forms of incomitant strabismus.
• Do not confuse with H50.131 (right eye) or H50.133 (bilateral).
