Vitiligo of right eye, unsp eyelid and periocular area

This code signifies the presence of vitiligo affecting the skin of the right eyelid and/or the surrounding periocular region. Vitiligo is a chronic autoimmune condition characterized by depigmentation, resulting in white patches due to the loss of melanocytes. In this specific instance, the affected area is limited to the right eye.

Apply this code when documentation explicitly states vitiligo of the right eye, without further specification of which eyelid (upper or lower) is involved. This code is appropriate when the physician's notes confirm the diagnosis of vitiligo localized to the right periocular area.

• Ensure the documentation specifies the right eye; laterality is crucial for accurate coding.
• Do not use this code if a specific eyelid (e.g., right upper eyelid) is documented; more specific codes exist.
• Confirm the diagnosis of vitiligo is clearly stated, not just "depigmentation" or "white patches" without a definitive diagnosis.
