Ghost vessels (corneal), bilateral

This code signifies the presence of ghost vessels in the cornea of both eyes. Ghost vessels are non-perfused, empty blood vessels that remain in the corneal stroma after a period of inflammation and neovascularization has resolved. They appear as faint, thread-like structures and do not carry blood flow.

Use this code when documentation explicitly states the presence of ghost vessels affecting both corneas. This condition is often a sequela of previous corneal inflammation, infection, or trauma that led to corneal neovascularization. Documentation should clearly indicate the bilateral nature of these vessels.

• Ensure the documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Do not confuse ghost vessels with active corneal neovascularization, which indicates ongoing blood flow.
• Consider coding any underlying or associated corneal conditions that led to the development of these ghost vessels, if still present and clinically relevant.
