Vitiligo of unsp eye, unspecified eyelid and periocular area

This code describes the presence of vitiligo affecting the skin of the eyelid and/or the surrounding periocular region, when the specific eye involved is not documented. Vitiligo is a chronic autoimmune condition characterized by depigmentation, resulting in white patches on the skin. This diagnosis indicates the depigmentation is localized to the eye area.

Use this code when the medical record clearly documents vitiligo affecting the eyelid or periocular skin, but does not specify whether it's the right, left, or bilateral eye. Documentation should confirm the diagnosis of vitiligo and its anatomical location around the eye. This code is appropriate when laterality cannot be determined from the available clinical notes.

• Avoid using this code if laterality (right, left, or bilateral) is specified in the documentation; instead, use the more specific codes (H02.731, H02.732, H02.733).
• Ensure the documentation explicitly states "vitiligo" and its involvement of the eyelid or periocular area, not just general depigmentation.
• Do not confuse with other eyelid pigmentary disorders or inflammatory conditions; this code is specific to vitiligo.
