Variations in hair color

This code signifies a departure from a person's typical or expected hair color, encompassing conditions like premature graying, poliosis (localized patches of white hair), or other congenital or acquired alterations in hair pigmentation. It describes the phenotypic presentation of hair color abnormalities rather than the underlying cause.

Apply this code when documentation explicitly states variations in hair color, such as "premature graying," "poliosis," or "heterochromia of hair." It is appropriate for reporting a cosmetic concern or a symptom that may be associated with other conditions, but not for the underlying condition itself.

• Do not use this code for normal age-related graying unless specifically documented as "premature."
• Code any underlying systemic conditions causing the hair color variation (e.g., vitiligo, Waardenburg syndrome) in addition to this code.
• This code is for the variation itself, not for hair dye or artificial color changes.
