Folliculitis decalvans
ICD-10 L66.2 is a billable code used to indicate a diagnosis of folliculitis decalvans.
Folliculitis decalvans is a chronic inflammatory condition characterized by the progressive loss of hair due to inflammation of hair follicles. It primarily affects the scalp and is marked by the presence of pustules, crusting, and scarring. The condition can lead to permanent hair loss if not treated effectively. The pathophysiology involves an autoimmune response that targets the hair follicles, resulting in follicular destruction and subsequent cicatricial alopecia. Diagnosis is typically made through clinical examination, supported by a biopsy that reveals follicular inflammation and destruction. Differential diagnoses include other forms of alopecia, such as alopecia areata and lichen planopilaris. Treatment options may include topical and systemic corticosteroids, antibiotics, and immunosuppressive agents, but the condition often requires a multidisciplinary approach for optimal management.

L66.2 specifically covers folliculitis decalvans, which is characterized by follicular inflammation leading to hair loss. It is distinct from other conditions like folliculitis or alopecia areata.
L66.2 should be used when there is clear evidence of folliculitis decalvans, particularly when there is scarring and chronic inflammation of hair follicles, differentiating it from non-scarring alopecias.
Documentation should include clinical findings such as pustules, scarring, and hair loss patterns, along with treatment history and any biopsy results that confirm the diagnosis.
