Infantile papular acrodermatitis [Gianotti-Crosti]
ICD-10 L44.4 is a billable code used to indicate a diagnosis of infantile papular acrodermatitis [gianotti-crosti].
Infantile papular acrodermatitis, also known as Gianotti-Crosti syndrome, is a benign viral exanthem primarily affecting infants and young children. Clinically, it presents as a distinctive rash characterized by papular lesions that are typically symmetrically distributed on the extremities, buttocks, and face. The lesions are often erythematous and can be pruritic, with a tendency to resolve spontaneously within weeks. The condition is frequently associated with viral infections, particularly those caused by hepatitis A, Epstein-Barr virus, and cytomegalovirus. The pathophysiology involves an immune-mediated response to viral antigens, leading to the characteristic skin manifestations. Diagnosis is primarily clinical, supported by patient history and physical examination, as laboratory tests are not routinely required. Differential diagnoses include other viral exanthems and allergic reactions. Understanding the disease progression is crucial, as the condition is self-limiting, and treatment is generally symptomatic, focusing on itch relief and skin care.

L44.4 specifically covers infantile papular acrodermatitis, which is characterized by papular lesions in children, often following viral infections. It is important to differentiate it from other viral exanthems and allergic reactions.
L44.4 should be used when the clinical presentation aligns with Gianotti-Crosti syndrome, particularly when there is a history of recent viral infection. It is distinct from other codes that may describe similar rashes without the viral association.
Documentation should include a detailed clinical description of the rash, patient history of recent viral infections, and any associated symptoms. Photographic evidence may also support the diagnosis.
