Other lichen planus
ICD-10 L43.8 is a billable code used to indicate a diagnosis of other lichen planus.
Lichen planus is a chronic inflammatory condition affecting the skin and mucous membranes, characterized by pruritic, polygonal, flat-topped papules that can vary in color from purple to brown. Other lichen planus (L43.8) encompasses forms of lichen planus that do not fit the classic presentation or involve atypical sites. The condition primarily affects the skin, but can also involve the oral cavity, nails, and genital areas. The pathophysiology involves an immune-mediated response, leading to a band-like infiltrate of lymphocytes at the dermal-epidermal junction. Disease progression can vary; while some patients experience spontaneous resolution, others may have chronic or recurrent episodes. Diagnostic considerations include a thorough clinical examination, patient history, and, in some cases, skin biopsy to confirm the diagnosis and rule out other conditions. Differential diagnoses may include psoriasis, eczema, and other papulosquamous disorders. Management typically involves topical corticosteroids, systemic therapies for severe cases, and patient education regarding potential triggers.

L43.8 covers atypical presentations of lichen planus that do not conform to the classic form, including variants such as lichen planus pigmentosus and lichen planus of the mucous membranes.
L43.8 should be used when the lichen planus presentation is atypical or when the condition affects areas not typically covered by other specific lichen planus codes.
Documentation should include a detailed clinical examination, patient history, treatment plans, and any biopsy results that confirm the diagnosis of atypical lichen planus.
