ICD-10 Code L68.9 – Hypertrichosis, unspecified (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L68.9 – Hypertrichosis, unspecified
What it is
L68.9 identifies hypertrichosis when excessive hair growth is documented but the type or cause is not specified. Use it for generalized or localized hair overgrowth when no more precise diagnosis is recorded.
Clinical signs
Clinical features vary; refer to documentation. Typical notes describe increased terminal or fine hair growth beyond expected for age, sex, or body area, without enough detail to classify a specific subtype.
When to use this code
Use L68.9 when the provider documents hypertrichosis and does not name a cause, pattern, or associated condition. It is appropriate when the chart only states excessive hair growth or abnormal hair distribution. If the record later identifies a specific disorder, code that diagnosis instead.
Do not use for
Do not use this code for hirsutism, androgen-related hair growth, or hair changes clearly linked to another condition. Check documentation when the note describes a known congenital syndrome, medication effect, or endocrine disorder.
Coding tip
Query for laterality, distribution, and cause if the record only says “excess hair,” because a more specific code may be available.
