ICD-10 Code L68.8 – Other hypertrichosis (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L68.8 – Other hypertrichosis
What it is
Use this code for excessive hair growth that does not fit a more specific hypertrichosis category. It covers unusual hair growth patterns documented as “other” by the clinician.
Clinical signs
Clinical features vary; refer to documentation. Typical notes describe increased hair growth beyond what is expected for age, sex, or body site, without a more specific diagnosis.
When to use this code
Use L68.8 when the record clearly identifies hypertrichosis but does not specify a different type. It is appropriate when the provider documents an atypical or unspecified pattern of excess hair growth.
If the chart names a more specific cause or subtype, code that condition instead. Check documentation when the etiology, distribution, or associated disorder is unclear.
Do not use for
Do not use this code for hirsutism, congenital generalized hypertrichosis, or hair growth explained by another documented disorder. Check documentation if the note suggests a different diagnosis.
Coding tip
Query the provider when the term “hypertrichosis” appears without detail, so you can confirm whether L68.8 is the best available code.
