ICD-10 Code H11.31 – Conjunctival hemorrhage, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.31 – Conjunctival hemorrhage, right eye
What it is
This code identifies a localized bleed under the conjunctiva in the right eye. It usually appears as a bright red patch on the white of the eye.
Clinical signs
Typical findings include a sharply defined, painless red area on the sclera with no discharge or vision loss. Clinical features vary; refer to documentation.
When to use this code
Use H11.31 when the provider documents conjunctival hemorrhage limited to the right eye. It is appropriate when the record specifies the laterality and does not describe a more general eye hemorrhage. Code it from exam findings or a confirmed diagnosis, not from patient concern alone.
Do not use for
Do not use this code if the hemorrhage is documented in the left eye, both eyes, or an unspecified eye. Check documentation if the note describes another ocular bleed or a different conjunctival disorder.
Coding tip
Always verify laterality in the assessment, because this code is specific to the right eye.
