Aspergillosis of lung

BILLABLE STATUSYes
IMPLEMENTATION DATEOctober 1, 2015

Code Description

ICD-10 B48.3 is a billable code used to indicate a diagnosis of aspergillosis of lung.

Key Diagnostic Point:

Aspergillosis of the lung is a fungal infection caused by the Aspergillus species, primarily Aspergillus fumigatus. This condition can manifest in various forms, including allergic bronchopulmonary aspergillosis (ABPA), chronic pulmonary aspergillosis (CPA), and invasive aspergillosis. Patients with compromised immune systems, such as those with HIV/AIDS, cancer, or those undergoing immunosuppressive therapy, are at a higher risk for developing this infection. Symptoms may include cough, hemoptysis, fever, and chest pain. Diagnosis typically involves imaging studies such as chest X-rays or CT scans, along with microbiological cultures or serological tests. Treatment often includes antifungal medications such as voriconazole or amphotericin B, depending on the severity and type of aspergillosis. Early diagnosis and appropriate antifungal therapy are crucial for improving patient outcomes, especially in immunocompromised individuals.

Code Complexity Analysis

Complexity Rating: Medium

Medium Complexity

Complexity Factors

  • Differentiating between types of aspergillosis (e.g., ABPA vs. invasive aspergillosis)
  • Need for detailed patient history regarding immunocompromised status
  • Variability in clinical presentation and diagnostic criteria
  • Potential for co-infection with other pathogens

Audit Risk Factors

  • Inadequate documentation of immunocompromised status
  • Failure to specify the type of aspergillosis
  • Lack of supporting diagnostic tests
  • Inconsistent treatment documentation

Diagnostic & Documentation Impact

Enhanced Specificity

ICD-10 Improvements

The transition to ICD-10 has allowed for more specific coding of aspergillosis, improving the ability to track and manage cases effectively. This specificity aids in better treatment planning and resource allocation.

ICD-9 vs ICD-10

The transition to ICD-10 has allowed for more specific coding of aspergillosis, improving the ability to track and manage cases effectively. This specificity aids in better treatment planning and resource allocation.

Reimbursement & Billing Impact

The transition to ICD-10 has allowed for more specific coding of aspergillosis, improving the ability to track and manage cases effectively. This specificity aids in better treatment planning and resource allocation.
