Paving stone degeneration of retina, unspecified eye

This code represents a degenerative retinal condition characterized by sharply demarcated, often circular or oval, areas of retinal thinning and atrophy, typically found in the peripheral retina. These lesions expose the underlying choroid and sclera, resembling cobblestones or paving stones. It is generally considered a benign condition and rarely progresses to retinal detachment.

Use this code when documentation specifies "paving stone degeneration" or "cobblestone degeneration" of the retina without further specification of the affected eye. This diagnosis is typically made during a dilated fundus examination. Documentation should clearly indicate the presence of this specific retinal finding.

• Do not use this code if the laterality (right or left eye) is documented; instead, choose the more specific H35.431 or H35.432.
• This code describes a degenerative change, not an active inflammatory or infectious process.
• Paving stone degeneration is distinct from other peripheral retinal degenerations like lattice degeneration, which carries a higher risk of retinal detachment.
