ICD-10 Code H11.231 – Symblepharon, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.231 – Symblepharon, right eye
What it is
H11.231 identifies symblepharon in the right eye, meaning abnormal adhesion between the eyelid lining and the eyeball surface. It reflects a structural conjunctival problem that can limit normal eye movement.
Clinical signs
Typical findings include visible conjunctival scarring and tethering of the eyelid to the globe. Clinical features vary; refer to documentation for extent, location, and whether the right eye is specifically involved.
When to use this code
Use this code when the record clearly documents symblepharon affecting the right eye. It is appropriate when the provider identifies conjunctival adhesion, scar-related tethering, or a postoperative or inflammatory sequela limited to the right side.
Code only when laterality is documented. If the note describes bilateral disease, another code may apply; if the eye side is not stated, check documentation.
Do not use for
Do not use this code for nonspecific conjunctivitis, eyelid adhesions without conjunctival involvement, or unspecified eye laterality. Check documentation if the record uses only general scarring terms.
Coding tip
Confirm the right eye is explicitly stated, because laterality is built into H11.231.
