Alopecia (capitis) totalis
ICD-10 L63.0 is a billable code used to indicate a diagnosis of alopecia (capitis) totalis.
Alopecia totalis is a severe form of alopecia areata characterized by the complete loss of hair on the scalp. This autoimmune condition occurs when the immune system mistakenly attacks hair follicles, leading to hair loss. Clinically, patients may present with sudden, patchy hair loss that can progress to total scalp hair loss. The condition can affect individuals of any age but is most commonly seen in young adults and adolescents. The pathophysiology involves a complex interplay of genetic predisposition and environmental triggers, which can include stress or viral infections. Disease progression can vary; some patients may experience spontaneous regrowth, while others may have persistent hair loss. Diagnostic considerations include a thorough clinical examination, patient history, and sometimes a scalp biopsy to rule out other conditions. The diagnosis of alopecia totalis is primarily clinical, based on the characteristic presentation of complete scalp hair loss without scarring.

L63.0 specifically covers alopecia totalis, which is the complete loss of hair on the scalp. It is distinct from other forms of alopecia, such as alopecia areata (L63.1), which may involve patchy hair loss.
L63.0 should be used when there is a confirmed diagnosis of total hair loss on the scalp. It is important to differentiate it from other alopecia codes based on the extent of hair loss and clinical presentation.
Documentation should include a detailed patient history, clinical examination findings, and any relevant laboratory or biopsy results that confirm the diagnosis of alopecia totalis.
