ICD-10-CM code L64.8 designates 'Other androgenic alopecia,' an active diagnosis concept categorized under parent code L64. The code exists within a hierarchy including drug-induced and unspecified variants. Clinical literature describes androgenic alopecia as male pattern hair loss in men, for which finasteride is an FDA-approved pharmacologic treatment that slows hair loss. 1 2 4

Plain-language overview

Androgenic alopecia is a medical condition characterized as male pattern hair loss in men, for which finasteride is an FDA-approved pharmacologic treatment that slows hair loss but does not completely halt it. 2

Patients receiving finasteride treatment for androgenic alopecia experience a reversal of hair count within twelve months, and dermatologists prescribe this medication for managing this specific condition. 2

What the sources add

While terminology records establish L64.8 as an active diagnostic concept, clinical literature provides operational context by identifying finasteride as an FDA-approved treatment that reduces DHT but does not completely stop hair loss. 1 2
