Lattice degeneration of retina, unspecified eye

This code represents lattice degeneration, a peripheral retinal thinning disorder characterized by sharply demarcated, spindle-shaped areas of retinal atrophy. These areas often have overlying vitreous liquefaction and adhesion, increasing the risk of retinal tears and detachment.

Use this code when documentation confirms the diagnosis of lattice degeneration of the retina without specifying laterality. This diagnosis is typically made during a dilated fundus examination. It is appropriate when the medical record does not indicate whether the condition affects the right or left eye, or if it is bilateral.

• Do not use this code if laterality is specified; instead, use H35.411 (right eye) or H35.412 (left eye).
• Ensure the documentation clearly states "lattice degeneration" to support this code.
• Code any associated retinal tears or detachments separately and sequence them according to coding guidelines.
