Variations in hair color

This code describes congenital or acquired abnormalities in the pigmentation of hair, leading to unusual or inconsistent hair coloration. It encompasses conditions where the hair color deviates from the expected norm for the individual, without necessarily indicating a systemic disease.

Use this code when documentation specifies a variation in hair color, such as poliosis (localized patches of white hair), premature graying, or other dyschromias of the hair. This code is appropriate when the hair color variation is the primary reason for the encounter or a significant finding.

• Do not use for normal variations in hair color that are not considered abnormal or a clinical concern.
• Consider if an underlying systemic condition is causing the hair color change; if so, code the underlying condition first.
• Differentiate from hair loss (alopecia) or other structural hair abnormalities, which have distinct codes.
