Paving stone degeneration of retina, bilateral

This code describes a degenerative retinal condition affecting both eyes, characterized by sharply demarcated, often depigmented, chorioretinal atrophy. These lesions, resembling paving stones, are typically found in the peripheral retina and are generally benign, rarely progressing to more severe vision loss.

Use this code when documentation explicitly states "paving stone degeneration" or "cobblestone degeneration" and specifies involvement of both eyes. This diagnosis is typically made during a dilated fundus examination. Supporting documentation should include ophthalmologist notes detailing the presence and bilateral nature of these peripheral retinal lesions.

• Ensure the documentation clearly specifies "bilateral" involvement; otherwise, use the appropriate unilateral or unspecified eye code.
• Do not confuse paving stone degeneration with other peripheral retinal degenerations like lattice degeneration, which has different clinical implications and coding.
• This is a diagnosis code; it will often be accompanied by codes for other ocular conditions if present.
