Elephantiasis of unspecified eye, unspecified eyelid

This code describes a chronic, severe swelling and thickening of the eyelid tissue due to lymphatic obstruction, specifically when the affected eye and eyelid are not specified in the medical record. It represents a late-stage manifestation of lymphedema affecting the ocular adnexa, leading to disfigurement and potential functional impairment.

Apply this code when documentation clearly indicates elephantiasis of an eyelid, but the laterality of the eye (right, left, or bilateral) and the specific eyelid (upper or lower) are not precisely documented. This code is appropriate when the physician's notes confirm the diagnosis of elephantiasis affecting the eyelid without further anatomical specificity.

• Avoid using this code if the medical record specifies the affected eye (e.g., right eye, left eye) or the specific eyelid (e.g., upper eyelid, lower eyelid); more specific codes are available.
• Ensure documentation supports the diagnosis of elephantiasis, not just general eyelid edema, which would be coded differently.
• Consider sequencing this code after any underlying cause of the lymphatic obstruction, if known and documented.
