ICD-10 Code L64.8 – Other androgenic alopecia (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L64.8 – Other androgenic alopecia
What it is
L64.8 identifies androgen-related hair loss that does not fit a more specific ICD-10 subtype. Use it for patterned alopecia when the record supports an androgenic cause but names no other category.
Clinical signs
Typical findings include gradual thinning of scalp hair, often in a patterned distribution. Clinical features vary; refer to documentation for the exact pattern, severity, and whether the diagnosis is confirmed.
When to use this code
Use L64.8 when the clinician documents other androgenic alopecia, androgen-related hair loss, or a similar nonspecific subtype. It also fits when the note clearly excludes a more specific androgenic alopecia code. If the record is vague, check documentation before assigning the code.
Do not use for
Do not use this code for hair loss from nonandrogen causes, such as scarring alopecia or alopecia areata. Also avoid it when the documentation supports a more specific androgenic alopecia code.
Coding tip
Match the code to the exact wording in the assessment and do not assume androgenic alopecia without clear provider documentation.
