H35.412

What This Code Means

Lattice degeneration is a thinning of the retina (the light-sensitive tissue at the back of the eye) that creates a lattice-like pattern, occurring in the left eye. This condition increases the risk of retinal tears or detachment but may not cause symptoms in early stages.

Coding Tips

• •Verify laterality is documented as left eye (H35.412) versus right eye (H35.411) or bilateral (H35.413) to ensure accurate code selection
• •Lattice degeneration is often an incidental finding during eye exams; confirm it is being actively managed or monitored before coding, and look for any associated retinal complications that may require additional codes
