Code Description

ICD-10 P61.1 is a billable code used to indicate a diagnosis of polycythemia neonatorum.

Key Diagnostic Point:

Polycythemia neonatorum is a hematological condition characterized by an elevated red blood cell mass in newborns, typically defined as a hematocrit greater than 65%. This condition can arise from various factors, including intrauterine hypoxia, maternal diabetes, and delayed cord clamping. Newborns with polycythemia may present with symptoms such as lethargy, poor feeding, and respiratory distress. The condition can lead to complications such as hyperbilirubinemia, thrombosis, and organ dysfunction if not managed appropriately. Diagnosis is primarily based on laboratory findings, including complete blood count and blood gas analysis. Treatment may involve hydration, phototherapy for jaundice, and in severe cases, partial exchange transfusion. Understanding the etiology and management of polycythemia neonatorum is crucial for neonatal care providers to prevent adverse outcomes.
