Code Description

ICD-10 B37 is a billable code used to indicate a diagnosis of candidiasis.

Key Diagnostic Point:

Candidiasis is a fungal infection caused by yeasts of the genus Candida, with Candida albicans being the most common species implicated in human infections. This condition can manifest in various forms, including oropharyngeal candidiasis (thrush), esophageal candidiasis, vulvovaginal candidiasis, and invasive candidiasis, which can affect the bloodstream and internal organs. The infection typically occurs in immunocompromised individuals, such as those with HIV/AIDS, cancer patients undergoing chemotherapy, organ transplant recipients, and patients on long-term corticosteroid therapy. Symptoms may vary depending on the site of infection but often include itching, irritation, and discomfort in localized areas, as well as systemic symptoms in cases of invasive candidiasis. Diagnosis is primarily based on clinical evaluation and laboratory tests, including culture and sensitivity testing. Treatment usually involves antifungal medications, such as fluconazole, itraconazole, or amphotericin B, depending on the severity and location of the infection. Prompt diagnosis and treatment are crucial to prevent complications, especially in immunocompromised patients.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variety of clinical presentations requiring specific documentation.
  • Differentiation between localized and systemic infections.
  • Potential for co-infections with other pathogens.
  • Need for accurate identification of immunocompromised status.

Audit Risk Factors

  • Inadequate documentation of immunocompromised status.
  • Failure to specify the type of candidiasis.
  • Incorrect coding of antifungal treatment regimens.
  • Lack of supporting lab results for diagnosis.
