Conjunctival cysts, bilateral

This code signifies the presence of benign, fluid-filled sacs or lesions located on the conjunctiva of both eyes. These cysts typically arise from obstructed ducts of accessory lacrimal glands or goblet cells, or from epithelial inclusions. They are generally asymptomatic but can cause irritation or foreign body sensation.

Apply this code when documentation explicitly states the diagnosis of conjunctival cysts affecting both the right and left eyes. This diagnosis is typically made during an ophthalmological examination. Ensure the medical record clearly indicates the bilateral nature of the condition.

• Do not use this code if the cysts are unilateral; instead, select the appropriate code for the affected eye (e.g., H11.441 for right, H11.442 for left).
• Distinguish conjunctival cysts from other conjunctival lesions like pterygium or pinguecula, which have distinct ICD-10-CM codes.
• Ensure the provider's documentation specifies "bilateral" or clearly indicates involvement of both eyes to support this code.
