Alopecia universalis
ICD-10 L63.1 is a billable code used to indicate a diagnosis of alopecia universalis.
Alopecia universalis is a severe form of alopecia areata characterized by the complete loss of hair on the scalp and body. Clinically, patients present with sudden onset of hair loss, often accompanied by a smooth, hairless scalp and loss of body hair, including eyebrows and eyelashes. The condition is thought to be an autoimmune disorder where the immune system mistakenly attacks hair follicles, leading to hair loss. The pathophysiology involves a complex interplay of genetic predisposition and environmental triggers, although the exact cause remains unclear. Disease progression can vary; some patients may experience spontaneous regrowth, while others may have persistent or recurrent hair loss. Diagnostic considerations include a thorough clinical examination, patient history, and sometimes a scalp biopsy to rule out other conditions. Differential diagnoses include other forms of alopecia, such as androgenetic alopecia and telogen effluvium, which can present similarly but have distinct underlying mechanisms.

L63.1 specifically covers alopecia universalis, which is characterized by total hair loss on the scalp and body. It is distinct from other forms of alopecia, such as alopecia areata (L63.0) and androgenetic alopecia (L65).
L63.1 should be used when a patient presents with complete hair loss on the scalp and body, differentiating it from other alopecia types that may not involve total hair loss.
Documentation should include a detailed patient history, clinical examination findings, and any relevant laboratory or biopsy results that confirm the diagnosis of alopecia universalis.
