ICD-10 Code H11.443 – Conjunctival cysts, bilateral (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H11.443 – Conjunctival cysts, bilateral
What it is
H11.443 identifies cysts involving the conjunctiva in both eyes. Use it when documentation clearly states bilateral conjunctival cysts, meaning fluid-filled sacs on the eye’s surface lining.
Clinical signs
Clinical features may include visible, translucent conjunctival lesions, mild irritation, foreign-body sensation, or a small painless bump. Clinical features vary; refer to documentation.
When to use this code
Use H11.443 when the provider documents conjunctival cysts in both eyes, or bilateral conjunctival cysts without a more specific alternative diagnosis. It is appropriate for office, ophthalmology, or problem-list documentation that confirms both sides. Check documentation if laterality is unclear.
Do not use for
Do not use this code for a cyst limited to one eye, which requires a unilateral code. Do not assign it when the finding is another conjunctival lesion or when documentation does not specify cysts.
Coding tip
Verify laterality in the assessment or impression before reporting H11.443.
