ICD-10 Code H02.856 – Elephantiasis of left eye, unspecified eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.856 – Elephantiasis of left eye, unspecified eyelid
What it is
This code identifies elephantiasis affecting the left eye region with the eyelid not otherwise specified. Use it when documentation describes marked chronic thickening or swelling of the left eyelid area.
Clinical signs
Typical findings include persistent enlargement, thickened skin, and a heavy or distorted eyelid appearance. Clinical features vary; refer to documentation for the exact laterality and eyelid detail.
When to use this code
Use H02.856 when the provider documents elephantiasis of the left eye area and does not specify the eyelid further. It is appropriate for chronic lymphatic-type swelling or tissue overgrowth noted on the left eyelid region. If the record names a different eyelid or a different eye, code that documented site instead.
Do not use for
Do not use this code for general eyelid edema, infection, or trauma without elephantiasis. Check documentation if the note describes bilateral involvement or a more specific eyelid diagnosis.
Coding tip
Verify both laterality and eyelid specificity before assigning H02.856.
