ICD-10 Code H11.821 – Conjunctivochalasis, right eye (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.821 – Conjunctivochalasis, right eye
What it is
H11.821 identifies conjunctivochalasis affecting the right eye. It means the conjunctiva is loose or redundant, creating folds that may interfere with normal tear flow or eyelid movement.
Clinical signs
Findings may include redundant conjunctival folds, especially along the lower lid margin, with irritation or a foreign-body sensation. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents conjunctivochalasis in the right eye specifically. It is appropriate when the condition is diagnosed on exam and laterality is clearly stated in the record. If both eyes are involved, check documentation for the correct bilateral or unspecified code.
Do not use for
Do not use H11.821 for nonspecific conjunctival irritation, conjunctivitis, or other eyelid disorders. If the record does not confirm right-eye involvement, check documentation.
Coding tip
Always verify laterality before assigning H11.821, because conjunctivochalasis codes are eye-specific.
