ICD-10 Code L68.3 – Polytrichia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L68.3 – Polytrichia
What it is
Polytrichia means excessive hair growth. Use this code when documentation describes abnormal hair growth that is more than expected for age, sex, or body area.
Clinical signs
Findings may include increased hair density, length, or distribution in localized or generalized areas. Clinical features vary; refer to documentation.
When to use this code
Use L68.3 when the provider documents polytrichia or excessive hair growth as the diagnosis. It may apply when the note describes the condition without identifying a more specific cause or subtype. Check documentation if the record instead supports hirsutism, hypertrichosis, or another hair disorder.
Do not use for
Do not use this code for normal hair variation, cosmetic hair concerns, or hair loss conditions. If the documentation names a different diagnosis, code that condition instead.
Coding tip
Code only when the provider clearly documents excessive hair growth, and query if the term is used loosely or without a diagnosis.
