Prurigo nodularis
ICD-10 L28.1 is a billable code used to indicate a diagnosis of prurigo nodularis.
Prurigo nodularis is a chronic skin condition characterized by the presence of multiple, itchy nodules that typically develop on the extremities, particularly the arms and legs. These nodules are often the result of repeated scratching or rubbing of the skin, leading to lichenification and thickening of the skin. The condition is associated with underlying pruritus, which can be severe and debilitating, significantly impacting the patient's quality of life. The pathophysiology of prurigo nodularis involves a complex interplay of neurogenic inflammation, immune response, and skin barrier dysfunction. Diagnosis is primarily clinical, based on the appearance of the nodules and the patient's history of itching. In some cases, a skin biopsy may be performed to rule out other conditions. Disease progression can lead to secondary infections due to skin breakdown from scratching. Management typically involves addressing the underlying itch, which may include topical corticosteroids, antihistamines, and in some cases, systemic therapies. Patients may also benefit from behavioral interventions aimed at reducing scratching.

L28.1 specifically covers prurigo nodularis, which is characterized by itchy nodules on the skin. It is important to differentiate it from other pruritic conditions such as eczema or psoriasis.
L28.1 should be used when the clinical presentation is consistent with prurigo nodularis, particularly when there is a history of chronic itching and nodular lesions. It is essential to differentiate it from other similar conditions based on clinical findings.
Documentation should include a detailed history of the patient's symptoms, physical examination findings, and any treatments attempted. A skin biopsy may be included if performed to confirm the diagnosis.
