Code Description

ICD-10 B39.1 is a billable code used to indicate a diagnosis of pulmonary coccidioidomycosis.

Key Diagnostic Point:

Pulmonary coccidioidomycosis is a fungal infection caused by the inhalation of spores from the Coccidioides species, primarily C. immitis and C. posadasii. This condition is endemic to certain regions, particularly the southwestern United States, parts of Mexico, and Central and South America. The infection can manifest as a mild respiratory illness or progress to more severe pulmonary disease, particularly in immunocompromised individuals. Symptoms may include cough, chest pain, fever, and fatigue. In some cases, it can lead to chronic pulmonary conditions or disseminated disease affecting other organs. Diagnosis is typically confirmed through serological tests, culture, or histopathological examination. Treatment often involves antifungal medications such as fluconazole or itraconazole, especially in cases of severe or disseminated disease. The management of pulmonary coccidioidomycosis requires careful consideration of the patient's immune status, as those who are immunocompromised are at a higher risk for severe disease and complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between acute and chronic forms of the disease.
  • Identifying immunocompromised patients who may present differently.
  • Understanding the geographic prevalence and exposure history.
  • Navigating the various antifungal treatment options and their indications.

Audit Risk Factors

  • Inadequate documentation of exposure history.
  • Failure to specify the severity of the disease.
  • Misclassification of the condition as a non-pulmonary form.
  • Lack of clarity regarding the patient's immunocompromised status.
