Conjunctival cysts, unspecified eye

This code signifies the presence of a fluid-filled sac or lesion on the conjunctiva, the mucous membrane lining the eyelids and covering the front of the eye, when the specific eye affected is not documented. These cysts are typically benign and can arise from various causes, including blocked ducts or inflammatory processes.

Use this code when the medical record clearly indicates a conjunctival cyst but does not specify whether it is in the right, left, or bilateral eye. Documentation should describe the presence of a cyst on the conjunctiva without further laterality detail.

• Avoid using this code if laterality (right, left, bilateral) is documented; instead, select the more specific H11.441, H11.442, or H11.443.
• Ensure the documentation specifies "conjunctival cyst" and not another type of conjunctival lesion, such as a nevus or tumor.
• This code is for the diagnosis of the cyst itself, not for any associated symptoms like irritation or foreign body sensation, which would be coded separately.
