ICD-10 Code H16.413 – Ghost vessels (corneal), bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.413 – Ghost vessels (corneal), bilateral
What it is
This code identifies ghost vessels in both corneas, meaning old, regressed blood vessels remain visible as faint, empty channels. Use it when the documentation specifically states bilateral corneal ghost vessels.
Clinical signs
Clinical features vary; refer to documentation. Findings may include faint, nonperfused corneal vascular remnants seen on slit-lamp exam, usually reflecting prior corneal neovascularization rather than active vessel growth.
When to use this code
Use H16.413 when the provider documents bilateral corneal ghost vessels as the diagnosis or a significant exam finding. It fits cases where the record distinguishes old, involuted vessels from active corneal neovascularization. Check documentation if laterality is unclear.
Do not use for
Do not use this code for active corneal neovascularization, corneal edema, or nonspecific corneal opacity unless ghost vessels are specifically documented. If only one eye is involved, use the appropriate unilateral code.
Coding tip
Code only when the chart states “ghost vessels” or an equivalent description of regressed corneal vessels, and confirm bilateral laterality before assigning H16.413.
