Elephantiasis of left lower eyelid

This code describes a chronic, severe lymphedema affecting the left lower eyelid, characterized by significant thickening and hardening of the skin and subcutaneous tissues. This condition results in gross enlargement and disfigurement of the eyelid, often impairing vision and eyelid function.

Use this code when documentation explicitly states elephantiasis or severe chronic lymphedema specifically affecting the left lower eyelid. This typically arises from parasitic infections (e.g., filariasis), recurrent inflammation, or severe lymphatic obstruction. Supporting documentation should detail the chronicity and significant tissue changes.

• Ensure the laterality (left) and specific eyelid (lower) are clearly documented to support this precise code.
• Distinguish from general edema or less severe forms of lymphedema; "elephantiasis" implies extreme, chronic changes.
• Code any underlying cause of the elephantiasis, such as filariasis (B74.-), as a primary diagnosis if applicable and documented.
