Other non-diabetic proliferative retinopathy, left eye

This code signifies the presence of abnormal new blood vessel growth (neovascularization) in the retina of the left eye, which is not caused by diabetes. This proliferation can lead to complications such as vitreous hemorrhage, retinal detachment, and vision loss.

Use this code when documentation specifies proliferative retinopathy in the left eye, and explicitly states that diabetes is not the underlying cause. This may be seen in conditions like sickle cell retinopathy, retinopathy of prematurity (in adults), or following retinal vein occlusion, when the proliferative stage is reached.

• Ensure documentation clearly specifies "non-diabetic" and the affected eye (left).
• Do not confuse with non-proliferative retinopathy codes; look for terms like "neovascularization" or "proliferative changes."
• If laterality is not specified, an unspecified eye code (H35.20) would be more appropriate.
