ICD-10 Code H02.851 – Elephantiasis of right upper eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.851 – Elephantiasis of right upper eyelid
What it is
H02.851 identifies elephantiasis affecting the right upper eyelid. It refers to marked, chronic thickening and enlargement of that eyelid; check documentation for the exact cause.
Clinical signs
Typical findings include persistent swelling, skin thickening, and enlargement of the right upper eyelid. Clinical features vary; refer to documentation for whether the condition is inflammatory, obstructive, or due to another cause.
When to use this code
Use this code when the provider documents elephantiasis specifically limited to the right upper eyelid. It is appropriate for chronic, localized eyelid enlargement that is not better described by a more specific underlying diagnosis. If the record only says eyelid edema or swelling, check documentation before coding H02.851.
Do not use for
Do not use it for nonspecific eyelid swelling, edema, or mass without documentation of elephantiasis. Avoid this code if the condition is on the left side, both sides, or another eyelid location.
Coding tip
Confirm laterality and the exact eyelid location in the provider note before assigning H02.851.
