Code Description

ICD-10 P39.3 is a billable code used to indicate a diagnosis of neonatal urinary tract infection.

Key Diagnostic Point:

Neonatal urinary tract infections (UTIs) are significant clinical concerns in the perinatal period, affecting newborns within the first 28 days of life. UTIs in neonates can arise from various factors, including anatomical abnormalities, urinary retention, and the presence of catheters. Symptoms may be subtle, often presenting as nonspecific signs such as irritability, poor feeding, or temperature instability. Diagnosis typically involves urinalysis and urine culture, with treatment necessitating appropriate antibiotics based on sensitivity patterns. Early recognition and management are crucial to prevent complications such as renal damage or sepsis. The incidence of UTIs in neonates is relatively low but can be higher in those with risk factors such as prematurity or congenital anomalies. Clinicians must remain vigilant for signs of infection, as the clinical presentation can differ significantly from older children and adults.
