ICD-10 Code L68.2 – Localized hypertrichosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L68.2 – Localized hypertrichosis
What it is
Localized hypertrichosis means excess hair growth limited to a specific area of the body. It is a descriptive diagnosis, so you should code it when the record documents focal, unusual hair growth without a broader hair-growth disorder.
Clinical signs
Typical findings include visibly increased terminal or fine hair over a confined patch of skin. Clinical features vary; refer to documentation for the exact site, pattern, and whether the finding is congenital or acquired.
When to use this code
Use L68.2 when the provider documents localized hypertrichosis as the diagnosis, such as hair excess on one limb, patch, or other limited area. It may also fit when the note describes focal abnormal hair growth and does not identify a different underlying condition. Check documentation if the hair growth is part of a syndrome, medication effect, or another coded disorder.
Do not use for
Do not use this code for generalized hypertrichosis, hirsutism, or normal body-hair variation. If the chart points to another cause or a more specific diagnosis, code that condition instead.
Coding tip
Look for the word “localized” or an anatomic site in the note before assigning L68.2.
