ICD-10 Code H02.852 – Elephantiasis of right lower eyelid (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code H02.852 – Elephantiasis of right lower eyelid
What it is
This code identifies elephantiasis affecting the right lower eyelid. It refers to marked chronic thickening and enlargement of that eyelid, usually from longstanding lymphatic obstruction or other persistent tissue change.
Clinical signs
Typical findings include a visibly enlarged, thickened, and heavy right lower eyelid with possible distortion of the lid margin. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents elephantiasis specifically involving the right lower eyelid. It is appropriate when the laterality and eyelid location are clearly stated in the record. If the note only says eyelid swelling or edema, check documentation before assigning this code.
Do not use for
Do not use this code for nonspecific eyelid edema, infection, or mass without documentation of elephantiasis. If the side or lower-lid location is missing, check documentation.
Coding tip
Verify both laterality and the exact eyelid site, because ICD-10-CM provides separate codes for each side and lid.
