Localized vascularization of cornea, bilateral

This code indicates the presence of new blood vessel growth specifically within the cornea of both eyes. This vascularization is localized, meaning it does not extend beyond the corneal tissue itself. It often signifies a response to chronic inflammation, infection, or injury.

Use this code when documentation clearly states "localized corneal vascularization" affecting both eyes. This can be seen in conditions like chronic keratitis, contact lens-induced hypoxia, or following corneal transplantation. Supporting documentation should specify laterality and the localized nature of the vascularization.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Distinguish localized corneal vascularization from more extensive neovascularization that might involve other ocular structures.
• Always code the underlying cause of the corneal vascularization first, if known and documented.
