Allergic bronchopulmonary aspergillosis

This code represents a severe hypersensitivity reaction to Aspergillus species, primarily Aspergillus fumigatus, occurring in the lungs. It is characterized by asthma, recurrent pulmonary infiltrates, and bronchiectasis, often seen in patients with pre-existing asthma or cystic fibrosis.

Use this code when documentation confirms a diagnosis of allergic bronchopulmonary aspergillosis (ABPA). This diagnosis is typically supported by clinical criteria such as asthma, eosinophilia, elevated IgE levels, positive Aspergillus skin test, and central bronchiectasis on imaging.

• Ensure documentation clearly distinguishes ABPA from other forms of aspergillosis, such as aspergilloma or invasive aspergillosis.
• Code any underlying conditions, such as asthma (J45.-) or cystic fibrosis (E84.-), as primary or secondary diagnoses as appropriate.
• Look for specific mention of "allergic bronchopulmonary" to differentiate from other Aspergillus infections of the lung.
