ICD-10 Code H16.412 – Ghost vessels (corneal), left eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.412 – Ghost vessels (corneal), left eye
What it is
H16.412 identifies ghost vessels in the cornea of the left eye. These are old, usually inactive corneal vessels that remain visible after prior neovascularization.
Clinical signs
Findings typically include faint, empty-appearing corneal vessels on examination of the left eye. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents ghost vessels specifically in the left cornea. It may be appropriate when describing a residual, inactive finding rather than active corneal neovascularization. Check documentation if laterality or activity is unclear.
Do not use for
Do not use this code for active corneal vascularization, unspecified corneal vessel disorders, or findings in the right eye. If the record does not clearly state ghost vessels, check documentation.
Coding tip
Confirm both laterality and the exact term “ghost vessels” before assigning H16.412.
