ICD-10 Code H11.233 – Symblepharon, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.233 – Symblepharon, bilateral
What it is
H11.233 identifies symblepharon affecting both eyes. This means the eyelid lining is abnormally attached to the conjunctiva of the eye.
Clinical signs
Findings may include restricted eye movement, visible adhesions between the eyelid and globe, and irritation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly documents bilateral symblepharon. It is appropriate for confirmed conjunctival adhesions involving both eyes, whether noted on exam or in specialist documentation. If the laterality is not stated, check documentation before coding.
Do not use for
Do not use this code for unilateral symblepharon or for nonspecific conjunctival scarring without adhesion. Check documentation if the note only describes ocular irritation or prior eye surgery.
Coding tip
Confirm both laterality and the presence of true conjunctival adhesion before assigning H11.233.
