Code Description

ICD-10 P37.2 is a billable code used to indicate a diagnosis of neonatal (disseminated) listeriosis.

Key Diagnostic Point:

Neonatal disseminated listeriosis is a severe infection caused by the bacterium Listeria monocytogenes, which can be transmitted from the mother to the fetus during pregnancy or through contaminated food. This condition is characterized by systemic infection in the newborn, often presenting with symptoms such as fever, irritability, poor feeding, respiratory distress, and signs of sepsis. The infection can lead to serious complications, including meningitis, septicemia, and even death if not promptly treated. Diagnosis typically involves blood cultures and clinical evaluation, with treatment requiring immediate initiation of appropriate antibiotics. The risk factors for listeriosis include maternal immunosuppression, advanced maternal age, and consumption of unpasteurized dairy products or undercooked meats. Early recognition and intervention are crucial in managing this condition effectively to reduce morbidity and mortality in affected neonates.

Code Complexity Analysis

Complexity Rating: High

High Complexity

Complexity Factors

  • Differentiating between listeriosis and other congenital infections
  • Need for comprehensive maternal history and dietary assessment
  • Potential for severe complications requiring intensive care
  • Variability in clinical presentation among neonates

Audit Risk Factors

  • Inadequate documentation of maternal history and risk factors
  • Failure to document clinical signs and symptoms accurately
  • Misclassification of the infection type (e.g., sepsis vs. listeriosis)
  • Lack of follow-up documentation on treatment outcomes

Specialty Focus

Medical Specialties

Neonatology

Documentation Requirements

Detailed clinical notes on the neonate's condition, including vital signs, laboratory results, and treatment plans.

Common Clinical Scenarios

Neonates presenting with sepsis-like symptoms in the NICU, requiring differential diagnosis for infectious etiologies.

Billing Considerations

Ensure accurate coding of associated conditions such as meningitis or septic shock, which may arise from listeriosis.

Pediatrics

Documentation Requirements

Comprehensive pediatric assessments, including developmental milestones and follow-up care plans.

Common Clinical Scenarios

Pediatric follow-up for neonates discharged after treatment for listeriosis, monitoring for long-term effects.

Billing Considerations

Consider the implications of maternal health on neonatal outcomes and document any relevant maternal infections.

Coding Guidelines

Inclusion Criteria

Use P37.2 When
  • Follow the official ICD
  • CM guidelines for coding infectious diseases, ensuring that all relevant clinical information is documented
  • Specific criteria for neonatal infections should be adhered to, including the need for laboratory confirmation and clinical correlation
