Paving stone degeneration of retina, left eye

This code describes a specific type of retinal degeneration characterized by sharply demarcated, round or oval areas of chorioretinal atrophy, often with visible choroidal vessels, located in the peripheral retina of the left eye. These lesions are typically asymptomatic and non-progressive.

Use this code when documentation explicitly states "paving stone degeneration" or "cobblestone degeneration" affecting the left eye. This diagnosis is typically made during a dilated fundus examination. Ensure the laterality is clearly specified in the physician's notes.

• Always confirm laterality (left eye) from the physician's documentation.
• Do not confuse with other types of peripheral retinal degeneration, such as lattice degeneration or retinoschisis.
• This is a diagnosis code; no procedure code is associated with the condition itself unless treatment for complications is performed.
