ICD-10 Code H16.441 – Deep Vascularization of Cornea, Right Eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H16.441 – Deep vascularization of cornea, right eye
What it is
This code identifies abnormal blood vessel growth into the deep layers of the cornea in the right eye. It indicates a localized corneal finding, not a general eye infection.
Clinical signs
Findings may include visible corneal vessels extending deeper than the superficial layers, often noted on slit-lamp examination. Clinical features vary; refer to documentation.
When to use this code
Use H16.441 when the provider documents deep vascularization of the cornea in the right eye as the diagnosis. It is appropriate when the record specifies laterality and does not describe a different corneal disorder as the primary finding. If the note only says corneal vascularization without eye laterality, check documentation.
Do not use for
Do not use this code for superficial corneal vascularization or for corneal neovascularization in the left eye or unspecified eye. Check documentation if the finding is part of another corneal condition.
Coding tip
Verify right-eye laterality in the provider note before assigning H16.441.
