2026 ICD-10-CM Diagnosis Code L67.9 – Hair color and hair shaft abnormality, unspecified
What it is
This code identifies an unspecified disorder of hair color or the hair shaft. Use it when the record notes an abnormality of hair appearance or structure, but does not define the exact type.
Clinical signs
Clinical features vary; refer to documentation. Findings may include unusual hair color, brittle or fragile hair, or other visible shaft changes noted on exam.
When to use this code
Use L67.9 when the provider documents a hair color or hair shaft abnormality without naming a specific diagnosis. It fits cases where the chart describes the problem, but details are incomplete. Check documentation if the abnormality is linked to a known inherited or acquired disorder.
Do not use for
Do not use this code when the record identifies a specific hair disorder, such as a named congenital or acquired condition. Also avoid it if the issue is only hair loss or scalp disease without hair shaft or color abnormality.
Coding tip
Code the most specific hair disorder documented; use L67.9 only when the exact abnormality is not stated.
