Convergence excess

Convergence excess is a form of esophoria or esotropia where the eyes over-converge, particularly at near vision, leading to symptoms like eye strain, double vision (diplopia), and headaches. This condition results from an overactive convergence reflex, causing the visual axes to cross inward more than necessary for the target distance.

This code is appropriate when documentation clearly indicates a diagnosis of convergence excess, often identified during an ophthalmic examination. Supporting documentation typically includes findings from cover-uncover tests, prism neutralization, and measurements of fusional vergence amplitudes, especially at near.

• Differentiate from other forms of esophoria or esotropia; this code specifically denotes the "excess" component.
• Ensure the documentation specifies the convergence anomaly is indeed an "excess" and not simply a basic esodeviation.
• Consider co-reporting with codes for associated symptoms like diplopia (H53.2) or asthenopia (H53.10) if documented.
