Code Description

ICD-10 P37.5 is a billable code used to indicate a diagnosis of neonatal candidiasis.

Key Diagnostic Point:

Neonatal candidiasis is a fungal infection caused by Candida species, primarily Candida albicans, that can occur in newborns, particularly those who are premature or have low birth weight. This condition is characterized by the presence of white patches in the oral cavity (thrush), diaper rash, and in severe cases, systemic infection. The risk factors include maternal diabetes, prolonged antibiotic use during labor, and immunosuppression. Diagnosis is typically made through clinical examination and, if necessary, culture of the organism. Treatment often involves antifungal medications, such as nystatin or fluconazole, and supportive care. Early recognition and management are crucial to prevent complications, including systemic candidiasis, which can lead to significant morbidity in neonates. The condition is part of a broader category of congenital infections that may also include congenital tuberculosis and toxoplasmosis, which can have overlapping clinical presentations and require careful differential diagnosis.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between localized and systemic candidiasis.
  • Identifying risk factors and comorbid conditions.
  • Understanding the implications of maternal health on neonatal outcomes.
  • Navigating the coding for associated conditions like thrush and diaper dermatitis.

Audit Risk Factors

  • Inadequate documentation of maternal health history.
  • Failure to specify the type of candidiasis (oral vs. systemic).
  • Misclassification of candidiasis severity.
  • Lack of follow-up documentation on treatment response.
