ICD-10 Code H11.243 – Scarring of Conjunctiva, Bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.243 – Scarring of conjunctiva, bilateral
What it is
H11.243 identifies scar tissue affecting the conjunctiva in both eyes. Use it when documentation states bilateral conjunctival scarring, fibrosis, or cicatricial change.
Clinical signs
Findings may include visible conjunctival scarring, symblepharon, or conjunctival shortening. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents scarring of the conjunctiva in both eyes as the diagnosed condition. It may appear after chronic inflammation, injury, or prior ocular disease, but you should code only what is explicitly documented.
If the record states bilateral involvement without naming a more specific underlying disorder, H11.243 is appropriate. If the scarring is described as unilateral or part of another coded condition, check documentation for the correct laterality and principal diagnosis.
Do not use for
Do not use H11.243 for conjunctival redness, irritation, or nonscarring conjunctivitis. Do not assign it when the chart does not clearly document bilateral scarring.
Coding tip
Confirm laterality in the ophthalmology note; bilateral scarring is required for H11.243.
