P36.2 Sepsis of newborn due to Staphylococcus aureus

Name of the Condition

• Sepsis of newborn due to Staphylococcus aureus
• ICD-10-CM Code: P36.2

Summary

This condition refers to a systemic infection in a newborn caused by Staphylococcus aureus, a bacterial pathogen. It involves the presence of this organism in the bloodstream and can lead to significant clinical manifestations, requiring prompt medical attention.

Causes

Sepsis in newborns due to Staphylococcus aureus is caused by the invasion of this bacterium into the bloodstream. Infections may originate from maternal transmission, environmental exposure, or healthcare-associated sources, such as contaminated equipment or surfaces.

Risk Factors

• Premature birth or low birth weight
• Maternal infections during pregnancy or delivery
• Prolonged rupture of membranes
• Invasive procedures (e.g., umbilical catheterization)
• Lack of infection control measures in healthcare settings
• Neonatal intensive care unit (NICU) admission

Symptoms

• Fever or hypothermia
• Lethargy or poor feeding
• Respiratory distress or apnea
• Jaundice or skin discoloration
• Irritability or lethargy
• Abdominal distension or vomiting

Diagnosis

Diagnosis is based on clinical evaluation, laboratory tests (e.g., blood cultures, complete blood count), and imaging as needed. Blood cultures are critical to identify the causative organism, and additional tests may assess organ function or signs of infection.

Treatment Options

Treatment typically involves intravenous antibiotics targeted against Staphylococcus aureus, such as vancomycin or nafcillin, guided by susceptibility testing. Supportive care, including respiratory support and fluid management, may also be necessary.

Prognosis and Follow-Up

Prognosis depends on the timeliness of treatment, the newborn’s overall health, and the presence of complications. Follow-up care may include monitoring for recurrence, developmental assessments, and long-term management of any resulting conditions.

Complications

• Meningitis or brain abscess
• Pneumonia or respiratory failure
• Sepsis-induced organ dysfunction
• Long-term neurodevelopmental delays
• Skin and soft tissue infections

Lifestyle & Prevention

Preventive measures include proper hand hygiene, sterile techniques during delivery and NICU care, and maternal screening for Staphylococcus aureus colonization when appropriate. Avoiding unnecessary invasive procedures can reduce risk.

When to Seek Professional Help

Seek immediate medical attention if a newborn exhibits signs of infection, such as fever, lethargy, poor feeding, or respiratory distress, especially within the first 28 days of life.

Tips for Medical Coders

Document the specific organism (Staphylococcus aureus) and any relevant details about the infection’s origin or complications. Ensure the code P36.2 is used when the causative agent is confirmed as Staphylococcus aureus and no more specific code applies.
