ICD-10 Code H11.24 – Scarring of conjunctiva (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.24 – Scarring of conjunctiva
What it is
H11.24 identifies scarring of the conjunctiva, the thin membrane covering the white of the eye and inner eyelids. Use it when documentation describes conjunctival fibrosis, cicatrix, or scar tissue affecting this surface.
Clinical signs
Findings may include visible conjunctival scar tissue, adhesions, or surface irregularity on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents conjunctival scarring as the diagnosis, whether localized or more extensive. It may apply after prior inflammation, surgery, injury, or other documented causes if the record specifically states scarring of the conjunctiva. Code the condition only when it is clinically noted and relevant to the encounter.
Do not use for
Do not use H11.24 for active conjunctivitis, conjunctival hemorrhage, or nonspecific eye irritation without scarring. Check documentation if the record mentions adhesions or other conjunctival disorders instead.
Coding tip
Look for the exact term “scarring” or “cicatrix” in the ophthalmology note before assigning H11.24.
