ICD-10 Code H02.855 – Elephantiasis of left lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.855 – Elephantiasis of left lower eyelid
What it is
H02.855 identifies elephantiasis affecting the left lower eyelid. Use it when documentation describes marked chronic thickening and enlargement of that eyelid, usually from longstanding lymphatic obstruction or similar tissue change.
Clinical signs
Typical findings include persistent swelling, thickened skin, and a heavy, enlarged eyelid contour. Clinical features vary; refer to documentation for laterality and whether the condition is isolated to the left lower eyelid.
When to use this code
Use this code when the provider specifically documents elephantiasis of the left lower eyelid. It is appropriate for confirmed unilateral lower eyelid involvement in the record, even if the underlying cause is not fully described. Check documentation if the note only says eyelid edema or swelling.
Do not use for
Do not use H02.855 for nonspecific eyelid swelling, ptosis, or edema without elephantiasis. Also avoid it when the condition involves a different eyelid or side; choose the code that matches the documented laterality.
Coding tip
Verify the exact eyelid and side in the ophthalmology note before assigning H02.855.
