Androgenic alopecia
Chapter 12:Diseases of the skin and subcutaneous tissue
ICD-10 L64 is a used to indicate a diagnosis of androgenic alopecia.
Androgenic alopecia, commonly known as male or female pattern baldness, is a hereditary condition characterized by progressive hair thinning and loss. It primarily affects the scalp, where hair follicles shrink over time due to the influence of androgens, particularly dihydrotestosterone (DHT). Clinically, it presents as a receding hairline in men and diffuse thinning over the crown in women. The condition typically begins in adulthood, with varying degrees of severity and onset age. The progression can be gradual, leading to significant psychological distress and social implications for affected individuals. Diagnosis is primarily clinical, based on patient history and physical examination, although dermatoscopy can assist in confirming the diagnosis by revealing miniaturized hair follicles. In some cases, a scalp biopsy may be warranted to rule out other causes of hair loss. Understanding the anatomy of hair follicles and the hormonal pathways involved is crucial for effective management and treatment planning.

L64 specifically covers androgenic alopecia, which includes male pattern baldness (L64.0) and female pattern hair loss (L64.1). It is characterized by a progressive thinning of hair due to genetic predisposition and hormonal influences.
L64 should be used when the diagnosis is specifically androgenic alopecia. If the hair loss is due to other causes, such as alopecia areata or telogen effluvium, different codes should be selected.
Documentation should include a thorough patient history detailing the onset and pattern of hair loss, physical examination findings, and any treatments attempted. Photographic evidence may also be beneficial.
