Other hair color and hair shaft abnormalities

This code represents various hair color and hair shaft abnormalities not classified elsewhere. It encompasses conditions such as premature graying (canities), poliosis (localized patches of white hair), and structural defects of the hair shaft like pili annulati (ringed hair) or trichorrhexis nodosa (nodular swellings on the hair shaft) when not due to a specific underlying disease.

Use this code when documentation specifies a hair color or hair shaft anomaly that is not congenital, acquired due to a specific disease, or otherwise classified. This includes idiopathic premature graying, poliosis without an identified systemic cause, or structural hair shaft defects not linked to a named syndrome or nutritional deficiency. Documentation should clearly describe the specific hair color or shaft abnormality.

• Do not use this code for congenital hair anomalies; refer to Q84.1 for those.
• Ensure the documentation specifies the hair color or shaft abnormality is not secondary to another condition, such as a nutritional deficiency or systemic disease.
• Consider codes for specific hair disorders (e.g., L63.- for alopecia) if the primary issue is hair loss rather than a color or shaft anomaly.
