Hypertrophic lichen planus
ICD-10 L43.0 is a billable code used to indicate a diagnosis of hypertrophic lichen planus.
Hypertrophic lichen planus is a variant of lichen planus characterized by thickened, hypertrophic plaques that typically appear on the lower extremities, particularly the shins. Clinically, these lesions are often pruritic, presenting as violaceous, shiny papules that can coalesce into larger plaques. The condition primarily affects the skin but can also involve mucosal surfaces, leading to discomfort and potential complications. The pathophysiology of hypertrophic lichen planus is believed to involve an autoimmune response, where T-lymphocytes attack the basal layer of the epidermis. Disease progression can vary, with some patients experiencing spontaneous resolution while others may have chronic, relapsing forms. Diagnostic considerations include a thorough clinical examination, patient history, and sometimes a skin biopsy to confirm the diagnosis and rule out other dermatological conditions such as psoriasis or eczema. Laboratory tests are generally not required unless secondary infections or other comorbidities are suspected.

L43.0 specifically covers hypertrophic lichen planus, which is characterized by thickened, hypertrophic plaques on the skin. It is important to differentiate this from other forms of lichen planus, such as erosive lichen planus or lichen planus of the mucosa.
L43.0 should be used when the clinical presentation is consistent with hypertrophic lichen planus, particularly when lesions are hypertrophic and located on the lower extremities. It is crucial to differentiate it from other lichen planus types based on clinical features and histological findings.
Documentation for L43.0 should include a detailed clinical examination, description of the lesions, patient history, and any relevant diagnostic tests, such as a skin biopsy if performed. Clear documentation of the treatment plan and response to therapy is also essential.
