Central retinal vein occlusion, right eye, w rtnl neovas

This code signifies a blockage of the central retinal vein in the right eye, leading to impaired blood flow and subsequent development of abnormal new blood vessels on the retina. This neovascularization can cause further vision loss due to hemorrhage or retinal detachment.

Apply this code when documentation confirms a diagnosis of central retinal vein occlusion affecting the right eye, specifically noting the presence of retinal neovascularization. This typically occurs in patients presenting with sudden, painless vision loss and funduscopic findings consistent with CRVO and new vessel formation.

• Ensure documentation clearly specifies "right eye" and the presence of "retinal neovascularization."
• Distinguish from non-ischemic CRVO or CRVO without neovascularization, which have different codes.
• Consider sequencing with codes for underlying systemic conditions contributing to CRVO, such as hypertension or diabetes.
