Lichen simplex chronicus
ICD-10 L28.0 is a billable code used to indicate a diagnosis of lichen simplex chronicus.
Lichen simplex chronicus is a skin condition characterized by thickened, leathery patches of skin resulting from chronic scratching or rubbing. It commonly occurs in areas prone to friction, such as the neck, scalp, and extremities. The condition is often associated with underlying dermatological issues like eczema or psoriasis, but it can also arise independently due to stress or anxiety. Clinically, patients present with pruritus (itching), which leads to a cycle of scratching and further skin irritation. The affected skin may appear hyperpigmented, and the texture is typically rough and thickened. Diagnosis is primarily clinical, based on the characteristic appearance and history of itching and scratching. A skin biopsy may be performed to rule out other conditions. Disease progression can lead to significant discomfort and secondary infections if not managed appropriately. Treatment focuses on breaking the itch-scratch cycle, often involving topical corticosteroids, antihistamines, and behavioral modifications to reduce scratching.

L28.0 specifically covers lichen simplex chronicus, which may occur as a result of other skin conditions like eczema or psoriasis but is characterized by its own distinct presentation of thickened, itchy skin.
L28.0 should be used when the primary issue is chronic itching and scratching leading to skin thickening, differentiating it from other dermatitis codes that may not involve the same chronic behavior.
Documentation should include a detailed patient history of itching and scratching, clinical examination findings, and any previous treatments attempted, as well as responses to those treatments.
