ICD-10 Code H11.419 – Vascular abnormalities of conjunctiva, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.419 – Vascular abnormalities of conjunctiva, unspecified eye
What it is
This code identifies an unspecified vascular abnormality affecting the conjunctiva, the thin membrane covering the white of the eye and inner eyelids. Use it when documentation confirms a conjunctival vascular lesion but does not name a more specific type.
Clinical signs
Findings may include visible abnormal conjunctival vessels, a localized vascular lesion, or a red, raised area on the conjunctiva. Clinical features vary; refer to documentation.
When to use this code
Use H11.419 when the provider documents a conjunctival vascular abnormality in one eye and does not specify the exact lesion type. It may apply when the note describes a vascular change, malformation, or lesion of the conjunctiva without further detail. Check documentation if laterality or lesion type is clearer.
Do not use for
Do not use this code for nonspecific conjunctival redness, inflammation, or trauma without a documented vascular abnormality. If the record names a different conjunctival disorder, code that condition instead.
Coding tip
Confirm the provider documented a vascular abnormality, not just eye redness, and verify laterality before assigning the code.
