ICD-10 Code L44.4 – Infantile papular acrodermatitis [Gianotti-Crosti] (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code L44.4 – Infantile papular acrodermatitis [Gianotti-Crosti]
What it is
L44.4 identifies infantile papular acrodermatitis, also called Gianotti-Crosti syndrome. It is a self-limited inflammatory skin condition that causes a distinctive papular rash in children.
Clinical signs
Typical findings include symmetric papules on the face, buttocks, and extensor surfaces of the limbs. Clinical features vary; refer to documentation if the rash pattern or associated findings are unclear.
When to use this code
Use L44.4 when the clinician documents Gianotti-Crosti syndrome or infantile papular acrodermatitis as the diagnosis. Code it when the record describes the characteristic papular eruption and no more specific alternate diagnosis is documented. If the note only says “rash,” check documentation.
Do not use for
Do not use this code for nonspecific dermatitis, urticaria, or viral exanthems without documentation of Gianotti-Crosti syndrome. Also avoid it when another confirmed skin disorder better explains the eruption.
Coding tip
Look for the exact diagnosis name in the assessment, not just a description of a pediatric rash.
