Vitiligo of left lower eyelid and periocular area

This code describes the depigmentation disorder, vitiligo, specifically affecting the skin of the left lower eyelid and the surrounding periocular region. It indicates a localized loss of melanocytes, resulting in characteristic white patches in this particular anatomical area.

Use this code when documentation clearly specifies vitiligo impacting the left lower eyelid and the adjacent periocular skin. This typically occurs when a dermatologist or ophthalmologist diagnoses the condition and precisely identifies the affected anatomical site.

• Ensure documentation specifies "left" lower eyelid and "periocular area" to support this specific code.
• Do not use this code for vitiligo affecting other parts of the eyelid or eye region; specific codes exist for other sites.
• Consider any associated conditions or complications of vitiligo, such as autoimmune disorders, and code them separately if documented.
