Unspecified corneal neovascularization, bilateral

This code describes the abnormal growth of new blood vessels into the cornea, affecting both eyes, where the specific type or cause of the neovascularization is not documented. Corneal neovascularization can impair vision by causing corneal opacification and can be a sign of underlying ocular disease or injury.

Use this code when documentation indicates corneal neovascularization in both eyes, but the provider has not specified the type (e.g., superficial, deep, pannus) or the underlying etiology. This code is appropriate when the medical record clearly states "bilateral corneal neovascularization" without further detail.

• Avoid using this code if the laterality is specified as unilateral (right or left eye); instead, use the appropriate unilateral code.
• Always query the provider for more specificity regarding the type and etiology of corneal neovascularization if possible, as more specific codes exist.
• Do not use this code if the documentation specifies a cause, such as chemical burns or other corneal disorders, as more specific codes linking to the etiology would be more appropriate.
