Neovascular secondary angle closure glaucoma, bilateral

This code signifies a severe form of glaucoma characterized by the formation of new, abnormal blood vessels in the iris and/or angle of the eye, leading to the closure of the drainage angle and subsequent elevation of intraocular pressure. This specific code indicates that both eyes are affected by this neovascular process.

Apply this code when documentation clearly states a diagnosis of neovascular secondary angle closure glaucoma affecting both eyes. Supporting documentation should include findings of neovascularization of the iris or angle, elevated intraocular pressure, and evidence of angle closure. This diagnosis often arises in patients with underlying conditions such as diabetic retinopathy or central retinal vein occlusion.

• 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) first, as this is a secondary glaucoma.
• Distinguish from primary angle closure glaucoma, which lacks the neovascular component.
