ICD-10 Code L68 – Hypertrichosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L68 – Hypertrichosis
What it is
Hypertrichosis means excessive hair growth beyond what is expected for age, sex, or body area. Use this code when the chart documents generalized or localized abnormal hair growth, not simply normal variation.
Clinical signs
Findings may include increased fine or coarse hair on the face, trunk, or limbs. Clinical features vary; refer to documentation for the pattern, extent, and whether the condition is congenital or acquired.
When to use this code
Use L68 when the provider diagnoses hypertrichosis and the record supports abnormal hair growth as the condition being addressed. It is appropriate when the note clearly distinguishes this from hirsutism or other hair disorders. If the documentation is unclear, check documentation.
Do not use for
Do not use this code for normal body hair, temporary hair changes, or hair growth better described as hirsutism. If the chart names a different hair or skin disorder, code that condition instead.
Coding tip
Code to the documented diagnosis and verify whether the provider specified congenital, acquired, generalized, or localized hypertrichosis.
