Cataract with neovascularization, bilateral

This code signifies the presence of cataracts in both eyes that are complicated by neovascularization. Neovascularization refers to the abnormal growth of new blood vessels, which can occur on the iris or in the angle of the eye, often associated with conditions like diabetic retinopathy or ischemic retinal vascular disease. This complication can lead to severe vision loss and secondary glaucoma.

Use this code when documentation clearly indicates bilateral cataracts with evidence of neovascularization affecting both eyes. This typically occurs in patients with underlying systemic conditions that predispose them to ocular ischemia. Supporting documentation would include ophthalmologist notes detailing the presence of cataracts and the observation of new vessel formation.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Always code the underlying cause of the neovascularization (e.g., diabetic retinopathy, retinal vein occlusion) as a primary or secondary diagnosis.
• Differentiate from other cataract types; this code is specific to the presence of neovascularization.
