Cysts of left lower eyelid

This code signifies the presence of a fluid-filled sac or abnormal pocket of tissue located on the lower eyelid of the patient's left eye. These cysts are typically benign and can vary in size and presentation, potentially causing irritation or cosmetic concerns.

Apply this code when documentation explicitly states a diagnosis of a cyst affecting the left lower eyelid. This includes conditions like sebaceous cysts, inclusion cysts, or other benign cystic formations in this specific anatomical location. Supporting documentation should clearly identify the laterality and location of the cyst.

• Ensure documentation specifies "left" and "lower" eyelid; otherwise, an unspecified or different laterality/location code may be more appropriate.
• Distinguish from chalazion (H00.0x-) or hordeolum (H00.0x-), which are inflammatory conditions, not simple cysts.
• If the cyst is excised, this diagnosis code would be linked to the appropriate CPT surgical code.
