ICD-10 Code L67.1 – Variations in hair color (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L67.1 – Variations in hair color
What it is
L67.1 identifies abnormal variation in hair color, such as uneven pigmentation or unusual lightening or darkening of the hair. Use it when the chart documents a hair-color change as the primary finding.
Clinical signs
Clinical features vary; refer to documentation. Findings may include patchy, diffuse, or otherwise atypical hair coloration noted on examination, without a more specific diagnosed cause.
When to use this code
Use this code when the provider documents variations in hair color as the condition being evaluated or recorded. It may fit office, dermatology, or general exam notes describing abnormal hair pigmentation. If the record identifies a specific underlying disorder, code that condition instead.
Do not use for
Do not use this code for normal hair color differences, cosmetic dyeing, or hair loss without color change. Check documentation if the color change is clearly secondary to another diagnosed disease.
Coding tip
Code the documented hair-color abnormality only when it is explicitly stated and not better explained by another diagnosis.
