2025 ICD-10-CM code P83.1
Neonatal erythema toxicum is a benign, self-limiting skin rash common in newborns.
No modifiers are typically applicable to ICD-10 codes.
Medical necessity for coding P83.1 is established when a newborn presents with a characteristic clinical picture of NET. No specific treatment is required, but documentation should support the diagnosis and rule out other underlying conditions.
The clinical responsibility for diagnosing and managing NET falls to the pediatrician or neonatologist.Documentation should include a thorough skin examination and description of the rash.No treatment is usually necessary, but observation and reassurance to parents are important.
In simple words: Neonatal erythema toxicum is a harmless rash that appears on many babies in their first few days of life. It looks like small red bumps and pimples, and it goes away on its own without any treatment.
Neonatal erythema toxicum (NET), also known as erythema toxicum neonatorum, is a common, self-limiting rash affecting newborns.It typically presents within the first 24-72 hours of life and usually resolves within 5-7 days without intervention.The rash is characterized by small, erythematous papules and pustules, often distributed over the body except for the palms and soles. The pustules contain eosinophils. The etiology is unknown, but it is not considered to be infectious.NET is usually asymptomatic and requires no specific treatment.
Example 1: A full-term infant is born and develops a generalized rash characterized by small, erythematous papules and pustules 48 hours after birth. The rash is present on the trunk and extremities, sparing the palms and soles.The infant is otherwise well and feeding well.Diagnosis: Neonatal erythema toxicum (P83.1)., A preterm infant, born at 32 weeks gestation, develops a rash similar to NET at 72 hours of life. The rash is milder than in the previous case.The infant is stable and receiving appropriate care. Diagnosis: Neonatal erythema toxicum (P83.1).Additional observation is warranted due to prematurity., A newborn is presenting with a rash that resembles NET, but the infant also shows signs of irritability and poor feeding.Further investigation is needed to rule out other conditions such as infection.P83.1 may be coded pending further diagnostic work-up.
Complete history and physical examination documenting the timing of rash onset (within first 72 hours), description of the rash (small, erythematous papules and pustules), distribution (generally sparing palms and soles), and absence of systemic symptoms.Consider noting any associated conditions such as prematurity.Photographs of the rash may also be helpful.
** This code is exclusively for newborns and should not be applied to maternal records.The rash is benign and self-limiting.Differential diagnosis should rule out other skin conditions.
