ICD-10 Code H11.33 – Conjunctival hemorrhage, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.33 – Conjunctival hemorrhage, bilateral
What it is
H11.33 identifies bleeding under the conjunctiva in both eyes. It describes a visible red patch on the white part of each eye, usually from small surface vessels.
Clinical signs
Typical findings include sharply demarcated, painless redness on the conjunctiva of both eyes. Vision is usually unaffected, and clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents conjunctival hemorrhage affecting both eyes. It fits cases described as bilateral subconjunctival or conjunctival bleeding without a more specific cause. If the record names an underlying injury or disease, code that condition as documented.
Do not use for
Do not use H11.33 for a unilateral conjunctival hemorrhage or for nonspecific eye redness without bleeding. Check documentation if the note describes trauma, infection, or another ocular disorder instead.
Coding tip
Confirm laterality in the chart; “bilateral” must be explicit before assigning H11.33.
