Elephantiasis of right lower eyelid

This code signifies a chronic, severe swelling of the right lower eyelid due to lymphatic obstruction, often resulting in thickened, leathery skin. This condition is a form of lymphedema specifically affecting the ocular adnexa.

Assign this code when documentation explicitly states elephantiasis or severe chronic lymphedema affecting the right lower eyelid. Supporting documentation should detail the specific eyelid involved and the characteristic skin changes consistent with elephantiasis.

• Ensure laterality is accurately documented and coded; this code specifies the right lower eyelid.
• Distinguish from general edema or cellulitis of the eyelid, which are temporary and lack the chronic, hypertrophic changes of elephantiasis.
• Consider co-occurring conditions that may cause or contribute to lymphatic obstruction, such as parasitic infections (e.g., filariasis) or malignancy.
