ICD-10 Code H16.41 – Ghost vessels (corneal) (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.41 – Ghost vessels (corneal)
What it is
H16.41 identifies ghost vessels in the cornea, meaning old blood vessels that have become faint or empty-looking. You use it when the corneal finding is documented as inactive or residual vascularization.
Clinical signs
Typical documentation describes translucent, threadlike corneal vessels or vessel remnants with little or no active blood flow. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider specifically documents ghost vessels in the cornea, usually as a residual finding on exam. It is appropriate when the record distinguishes these vessels from active corneal neovascularization or other corneal disorders. Check documentation if the note only says corneal vascularization.
Do not use for
Do not use H16.41 for active corneal neovascularization, corneal ulcer, or nonspecific corneal opacity. If the chart does not clearly identify ghost vessels, check documentation.
Coding tip
Code only when the provider names ghost vessels or documents an inactive residual vessel finding in the cornea.
