P36.0 Sepsis of newborn due to streptococcus, group B

Name of the Condition

• Sepsis of newborn due to streptococcus, group B
• ICD-10-CM Code: P36.0

Summary

This condition refers to sepsis in a newborn caused by group B streptococcus (GBS), a bacterial infection that can occur shortly after birth. It is a serious neonatal infection that requires prompt medical attention.

Causes

Group B streptococcus, a type of bacteria commonly found in the maternal genital or gastrointestinal tract, is the primary cause. The infection can be transmitted to the newborn during delivery or shortly after birth. Early-onset sepsis typically occurs within the first week of life, often due to exposure during labor.

Risk Factors

• Maternal colonization with group B streptococcus
• Prolonged rupture of membranes (≥18 hours)
• Preterm labor or delivery
• Maternal fever during labor
• Previous infant with invasive GBS disease

Symptoms

Symptoms may include respiratory distress, lethargy, poor feeding, irritability, grunting, or apnea. Newborns may also exhibit signs of infection such as temperature instability, hypotension, or skin discoloration.

Diagnosis

Diagnosis involves clinical evaluation of the newborn, including physical examination and laboratory tests. Blood cultures, complete blood counts, and inflammatory markers (e.g., C-reactive protein) are typically used to confirm infection. Maternal GBS screening results may also be considered.

Treatment Options

Treatment includes intravenous antibiotics, usually ampicillin and gentamicin, to target the infection. Supportive care, such as respiratory support or fluid management, may be necessary depending on the severity of the condition.

Prognosis and Follow-Up

With early and appropriate treatment, outcomes can be favorable. However, severe cases may lead to complications. Follow-up care includes monitoring for signs of recurrence or long-term effects, such as developmental delays or hearing loss.

Complications

Potential complications include meningitis, pneumonia, septic shock, or organ damage. Long-term sequelae may involve neurological impairment or chronic health issues.

Lifestyle & Prevention

Preventive measures include maternal GBS screening during pregnancy and antibiotic prophylaxis if colonization is detected. Proper hygiene and prompt medical care for maternal infections can reduce risk.

When to Seek Professional Help

Seek immediate medical attention if a newborn shows signs of infection, such as fever, poor feeding, or respiratory distress. Early intervention is critical to improve outcomes.

Tips for Medical Coders

Document the presence of group B streptococcus infection and its role in the newborn's sepsis. Ensure clinical documentation supports the diagnosis, including laboratory confirmation or maternal GBS status. Code P36.0 is specific to group B streptococcus; do not use for other bacterial causes.
