Code Description

ICD-10 B38.81 is a billable code used to indicate a diagnosis of prostatic coccidioidomycosis.

Key Diagnostic Point:

Prostatic coccidioidomycosis is a rare fungal infection caused by the Coccidioides species, primarily C. immitis and C. posadasii, which are endemic to certain regions, particularly the southwestern United States and parts of Central and South America. This condition occurs when the fungus enters the body, often through inhalation of spores, and can disseminate to various organs, including the prostate gland. Symptoms may include fever, chills, night sweats, weight loss, and localized pain in the pelvic region. In immunocompromised patients, such as those with HIV/AIDS, diabetes, or those on immunosuppressive therapy, the risk of developing disseminated coccidioidomycosis increases significantly. Diagnosis typically involves serological tests, culture, or histopathological examination of tissue samples. Treatment often includes antifungal medications such as fluconazole or itraconazole, with severe cases potentially requiring amphotericin B. Early diagnosis and appropriate antifungal therapy are crucial to prevent complications, including chronic infection or abscess formation in the prostate.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Limited awareness of coccidioidomycosis among healthcare providers.
  • Variability in clinical presentation, especially in immunocompromised patients.
  • Need for specific laboratory tests for accurate diagnosis.
  • Potential for misdiagnosis with other prostatic conditions.

Audit Risk Factors

  • Inadequate documentation of travel history to endemic areas.
  • Failure to document immunocompromised status.
  • Lack of specificity in clinical notes regarding symptoms.
  • Inconsistent use of antifungal treatment codes.
