ICD-10 Code H11.23 – Symblepharon (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.23 – Symblepharon
What it is
Symblepharon is an abnormal adhesion between the palpebral and bulbar conjunctiva, causing the eyelid lining to stick to the eyeball. It may limit normal eye movement and affect the ocular surface.
Clinical signs
Typical findings include visible conjunctival scarring, shortened fornix, and tethering of the eyelid to the globe. Clinical features vary; refer to documentation if the extent or cause is not clearly stated.
When to use this code
Use H11.23 when the provider documents symblepharon or adhesion of the conjunctiva between the eyelid and eye. Code it when the diagnosis is confirmed on exam, operative note, or specialist assessment. If the record only mentions scarring without adhesion, check documentation.
Do not use for
Do not use this code for nonspecific conjunctivitis, eyelid adhesions not involving the conjunctiva, or general ocular scarring without symblepharon. Check documentation when the anatomy is unclear.
Coding tip
Confirm that the note identifies conjunctival adhesion specifically, not just scarring or inflammation, before assigning H11.23.
