ICD-10 Code H11.3 – Conjunctival Hemorrhage (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.3 – Conjunctival hemorrhage
What it is
H11.3 identifies bleeding beneath the conjunctiva, the clear membrane covering the white of the eye. It usually appears as a sharply demarcated red patch and is often self-limited.
Clinical signs
Typical findings include a bright red or dark red area on the sclera without discharge or significant vision change. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents conjunctival hemorrhage, subconjunctival bleeding, or a similar diagnosis affecting the conjunctiva. Code it when the record clearly supports an isolated ocular bleed and no different primary eye disorder is documented. If the cause is specified, document it as directed.
Do not use for
Do not use H11.3 for conjunctivitis, trauma without hemorrhage, or bleeding from another eye structure. Check documentation if the note describes a different ocular surface lesion.
Coding tip
Confirm the provider’s exact wording, because “red eye” alone does not support H11.3.
