Elephantiasis of right eye, unspecified eyelid

This code describes a severe, chronic swelling of the right eyelid due to lymphatic obstruction, often caused by parasitic infection (filariasis). The eyelid tissue becomes thickened, indurated, and discolored, leading to significant disfigurement and potential vision impairment.

Use this code when documentation explicitly states "elephantiasis of the right eye" or "right eyelid elephantiasis" without further specification of the specific eyelid (e.g., upper or lower). This diagnosis is typically supported by physical examination findings detailing the characteristic chronic edema and thickening of the eyelid.

• Ensure the laterality is clearly documented as "right eye" or "right eyelid."
• If the specific eyelid (upper or lower) is documented, a more specific code from the H02.85- series should be used.
• Code any underlying parasitic infection (e.g., B74.- for filariasis) as an additional diagnosis.
