Ghost vessels (corneal), unspecified eye

This code signifies the presence of ghost vessels within the cornea, which are non-perfused, empty blood vessels that remain after a period of corneal neovascularization has regressed. These vessels appear as faint, thread-like structures and indicate a history of corneal inflammation or injury that led to new vessel formation.

Use this code when documentation explicitly states the presence of "ghost vessels" in the cornea, without specifying laterality. This typically occurs during an ophthalmological examination following resolution of active corneal neovascularization. The physician's notes should clearly identify these regressed vessels.

• Do not use this code for active corneal neovascularization; refer to codes in the H16.4- series for active vessel growth.
• If the laterality (right or left eye) is documented, use the more specific codes H16.411 or H16.412.
• Ensure the documentation differentiates ghost vessels from other corneal opacities or scars.
