Subcorneal pustular dermatitis
ICD-10 L13.1 is a billable code used to indicate a diagnosis of subcorneal pustular dermatitis.
Subcorneal pustular dermatitis, also known as Sneddon-Wilkinson disease, is a rare skin condition characterized by the presence of pustules located beneath the stratum corneum. Clinically, it presents as multiple, sterile pustules that can coalesce, primarily affecting the trunk and intertriginous areas. The condition is often associated with a history of inflammatory skin diseases, such as psoriasis or dermatitis. The pustules are typically asymptomatic but may be accompanied by erythema and scaling. The exact etiology remains unclear, but it is believed to involve an abnormal immune response. Disease progression can vary, with some patients experiencing recurrent episodes. Diagnosis is primarily clinical, supported by histopathological examination showing subcorneal pustules and a neutrophilic infiltrate. Differential diagnoses include other pustular dermatoses, such as pustular psoriasis and impetigo. Accurate diagnosis is crucial to avoid mismanagement and ensure appropriate treatment.

L13.1 specifically covers subcorneal pustular dermatitis, which is characterized by sterile pustules beneath the skin surface. It is important to differentiate it from other pustular conditions like pustular psoriasis and bacterial infections.
L13.1 should be used when the clinical presentation aligns with subcorneal pustular dermatitis, particularly when pustules are present without systemic symptoms or infection, distinguishing it from other pustular dermatoses.
Documentation should include clinical findings of pustules, any associated symptoms, and results from skin biopsies if performed. Detailed notes on the patient's history of skin conditions can also support the diagnosis.
