About the L64 Code Range
ICD-10 code L64 covers androgenic alopecia, a condition characterized by hair loss influenced by hormones. These codes specifically distinguish between general androgenic alopecia, drug-induced cases, other types, and unspecified forms.
These codes are used to accurately document hair loss related to androgen hormones. For example, L64.0 is for drug-induced androgenic alopecia, also known as drug-related alopecia or endocrine alopecia, helping clinicians record when medication causes this hair loss. L64.8 includes female pattern alopecia, male pattern alopecia, and other specific forms such as those linked to polycystic ovaries or postmenopause. Finally, L64.9 covers cases where the androgenic alopecia is unspecified but might also be called alopecia hereditaria or diffuse alopecia. Using these codes ensures precise classification for conditions commonly known as male and female pattern baldness, aiding clear communication and accurate medical records.
