Ophiasis
ICD-10 L63.2 is a billable code used to indicate a diagnosis of ophiasis.
Ophiasis is a specific variant of alopecia areata characterized by hair loss that occurs in a band-like pattern around the sides and back of the scalp. This condition primarily affects the hair follicles, leading to patchy hair loss that can progress to complete scalp baldness (alopecia totalis) or even total body hair loss (alopecia universalis). The clinical presentation typically includes well-defined, smooth patches of hair loss without inflammation or scarring. The underlying anatomy involved includes the hair follicles and the immune system, which plays a crucial role in the pathogenesis of this autoimmune disorder. Disease progression can vary significantly among individuals; some may experience spontaneous regrowth, while others may have recurrent episodes of hair loss. Diagnostic considerations for ophiasis include a thorough clinical examination, patient history, and, in some cases, a scalp biopsy to rule out other dermatological conditions. The diagnosis is often supported by the presence of exclamation mark hairs and the patient's history of other autoimmune diseases.

L63.2 specifically covers ophiasis, a variant of alopecia areata characterized by hair loss in a band-like pattern. It is important to differentiate this from other forms of alopecia, such as alopecia totalis or universalis.
L63.2 should be used when the clinical presentation aligns with ophiasis, particularly when hair loss is localized to the sides and back of the scalp. If the presentation is more generalized or involves complete scalp hair loss, other codes such as L63.0 or L63.1 may be more appropriate.
Documentation should include a detailed clinical examination noting the pattern of hair loss, any associated symptoms, and a history of autoimmune conditions. Photographic evidence may also be beneficial for accurate coding.
