Allergic bronchopulmonary aspergillosis

This code represents a hypersensitivity reaction to Aspergillus species, primarily A. fumigatus, occurring in the airways of individuals with asthma or cystic fibrosis. It is characterized by recurrent episodes of bronchial obstruction, inflammation, and bronchiectasis, often leading to progressive lung damage.

Use this code when documentation confirms a diagnosis of allergic bronchopulmonary aspergillosis, typically supported by clinical criteria such as asthma, eosinophilia, elevated IgE, Aspergillus precipitins, and central bronchiectasis. This diagnosis is often made by pulmonologists or allergists.

• Ensure documentation clearly distinguishes ABPA from other forms of aspergillosis, such as aspergilloma or invasive aspergillosis.
• Code any underlying conditions, such as asthma (e.g., 493.xx) or cystic fibrosis (e.g., 277.0x), as primary or secondary diagnoses as appropriate.
• Look for specific diagnostic criteria mentioned in the medical record to support the use of this code.
