Elephantiasis of left upper eyelid

This code signifies a chronic, severe swelling and thickening of the skin and subcutaneous tissue of the left upper eyelid, characteristic of elephantiasis. This condition results from lymphatic obstruction, leading to persistent lymphedema and fibrotic changes.

Apply this code when documentation clearly indicates elephantiasis affecting the left upper eyelid. This typically involves a diagnosis of chronic lymphedema with significant tissue hypertrophy and induration of the specified eyelid. Supporting documentation would include physician notes detailing the location, severity, and chronicity of the eyelid swelling.

• Ensure laterality is precisely documented and matches the code (left upper eyelid).
• Distinguish from acute or less severe forms of eyelid edema; elephantiasis implies chronic, severe lymphatic obstruction.
• Consider coding an underlying cause of lymphatic obstruction if known and documented, such as filariasis or surgical trauma.
