Code Description

ICD-10 B43.0 is a billable code used to indicate a diagnosis of icd-10 title: pulmonary blastomycosis.

Key Diagnostic Point:

Pulmonary blastomycosis is a fungal infection caused by the organism Blastomyces dermatitidis, which primarily affects the lungs but can disseminate to other parts of the body. The infection is typically acquired through inhalation of airborne spores found in soil and decaying organic matter. Patients may present with a range of respiratory symptoms, including cough, chest pain, fever, and difficulty breathing. In immunocompromised individuals, such as those with HIV/AIDS, cancer, or those on immunosuppressive therapy, the risk of severe disease and dissemination is significantly increased. Diagnosis is often confirmed through culture, serology, or histopathological examination of tissue samples. Treatment typically involves antifungal medications, with itraconazole and amphotericin B being the most commonly used agents. Early diagnosis and appropriate antifungal therapy are crucial to prevent complications and improve patient outcomes.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between pulmonary and extrapulmonary forms of blastomycosis.
  • Identifying immunocompromised patients who may present atypically.
  • Understanding the need for culture confirmation versus clinical diagnosis.
  • Navigating treatment options and their documentation requirements.

Audit Risk Factors

  • Inadequate documentation of immunocompromised status.
  • Failure to document the specific type of antifungal treatment administered.
  • Lack of culture or serology results in the medical record.
  • Misclassification of pulmonary blastomycosis as a different fungal infection.
