ICD-10 Code H11.30 – Conjunctival hemorrhage, unspecified eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.30 – Conjunctival hemorrhage, unspecified eye
What it is
This code identifies a bleed under the conjunctiva, the clear membrane covering the white of the eye, when the affected eye is not specified. It usually appears as a bright red patch and is often self-limited.
Clinical signs
Typical findings include a sharply demarcated red area on the sclera without purulent discharge or corneal involvement. Vision is usually unchanged, and clinical features vary; refer to documentation.
When to use this code
Use H11.30 when the record documents conjunctival hemorrhage but does not identify right or left eye. It fits isolated subconjunctival bleeding noted on exam, especially when the provider documents no other ocular diagnosis. If trauma, surgery, or another eye disorder is the stated cause, code the documented condition as well.
Do not use for
Do not use this code for subconjunctival hemorrhage with a specified eye, because laterality is required when documented. Avoid it if the redness is from conjunctivitis, trauma, or another ocular surface disorder. Check documentation.
Coding tip
Confirm whether the provider named the right or left eye before assigning this unspecified-eye code.
