Code Description

ICD-10 B41 is a billable code used to indicate a diagnosis of other forms of sporotrichosis.

Key Diagnostic Point:

Sporotrichosis is a fungal infection caused by the dimorphic fungus Sporothrix schenckii, which is commonly found in soil, plants, and decaying organic matter. The infection typically manifests as cutaneous lesions, but can also disseminate to other systems, particularly in immunocompromised patients. Other forms of sporotrichosis may include lymphocutaneous sporotrichosis, which presents with nodular lesions along lymphatic channels, and disseminated sporotrichosis, which can affect internal organs. The clinical presentation can vary significantly based on the host's immune status, with immunocompromised individuals experiencing more severe and systemic forms of the disease. Diagnosis is primarily through clinical evaluation and culture of the organism from affected tissues. Treatment often involves antifungal medications such as itraconazole or potassium iodide, with the choice of therapy influenced by the severity of the infection and the patient's immune status. In immunocompromised patients, aggressive treatment and monitoring are essential to prevent complications.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Variability in clinical presentation based on immune status
  • Differentiation from other fungal infections
  • Need for accurate documentation of symptoms and treatment response
  • Potential for systemic involvement in immunocompromised patients

Audit Risk Factors

  • Inadequate documentation of immunocompromised status
  • Failure to document treatment response
  • Misclassification of sporotrichosis as another fungal infection
  • Lack of follow-up documentation
