Cataract with neovascularization, left eye

This code signifies a cataract in the left eye that is complicated by the presence of abnormal new blood vessel formation (neovascularization). This neovascularization can occur on the iris, in the anterior chamber angle, or on the lens capsule, and is often associated with underlying conditions like diabetic retinopathy or retinal vein occlusion.

Apply this code when documentation explicitly states a cataract in the left eye with accompanying neovascularization. This is typically observed during ophthalmological examinations, such as slit-lamp biomicroscopy, where the new vessel growth is identified in conjunction with lens opacification.

• Ensure the documentation specifies "left eye" and clearly identifies neovascularization as a complication of the cataract.
• Do not use this code for cataracts without documented neovascularization; instead, select a more appropriate H25 or H26 code.
• Always code the underlying systemic condition (e.g., diabetes mellitus with ophthalmic complications) that may be causing the neovascularization, if documented.
