Aspergillosis (B44)

The ICD-10 codes in the B44 section categorize different types of aspergillosis, a range of infections caused by Aspergillus fungi. These codes help specify the exact form of aspergillosis diagnosed, from lung infections to allergic or disseminated forms.

ICD-10 code B44 refers broadly to aspergillosis infections. More specifically, B44.0 covers invasive pulmonary aspergillosis, also known as invasive fungal infection or subacute invasive pulmonary aspergillosis, which affects the lungs seriously. B44.1 includes other pulmonary aspergillosis varieties such as chronic fibrosing and cavitary types, often linked to pneumonia or bronchial inflammation caused by Aspergillus. Tonsillar aspergillosis is identified by B44.2. Disseminated or systemic forms, where infection spreads beyond the lungs, are coded as B44.7. Allergic bronchopulmonary aspergillosis, an allergic reaction affecting bronchial tubes, is classified under B44.81. There are also codes for other rare or unspecified aspergillosis infections, like cutaneous or cerebral aspergillosis (B44.89), and cases where the type is not specified (B44.9), which include several named infections by different Aspergillus species. Using these precise ICD-10 codes for aspergillosis supports accurate documentation and treatment planning by clearly reflecting each patient's specific fungal infection.

Clinical Terms

The following clinical terms provide additional context, helping users better understand the clinical background and common associations for each diagnosis listed in this section. Including related terms alongside ICD-10-CM codes supports coders, billers, and healthcare professionals in improving accuracy, enhancing documentation, and facilitating research or patient education.

Aspergillosis

Infections with fungi of the genus ASPERGILLUS.

Aspergillosis, Allergic Bronchopulmonary

Hypersensitivity reaction (ALLERGIC REACTION) to fungus ASPERGILLUS in an individual with long-standing BRONCHIAL ASTHMA. It is characterized by pulmonary infiltrates, EOSINOPHILIA, elevated serum IMMUNOGLOBULIN E, and skin reactivity to Aspergillus antigen.

Aspergillus

A genus of mitosporic fungi containing about 100 species and eleven different teleomorphs in the family Trichocomaceae.

Invasive Pulmonary Aspergillosis

Lung infections with the invasive forms of ASPERGILLUS, usually after surgery, transplantation, prolonged NEUTROPENIA or treatment with high-doses of CORTICOSTEROIDS. Invasive pulmonary aspergillosis can progress to CHRONIC NECROTIZING PULMONARY ASPERGILLOSIS or hematogenous spread to other organs.

Neuroaspergillosis

Infections of the nervous system caused by fungi of the genus ASPERGILLUS, most commonly ASPERGILLUS FUMIGATUS. Aspergillus infections may occur in immunocompetent hosts, but are more prevalent in individuals with IMMUNOLOGIC DEFICIENCY SYNDROMES. The organism may spread to the nervous system from focal infections in the lung, mastoid region, sinuses, inner ear, bones, eyes, gastrointestinal tract, and heart. Sinus infections may be locally invasive and enter the intracranial compartment, producing MENINGITIS, FUNGAL; cranial neuropathies; and abscesses in the frontal lobes of the brain.

Pulmonary Aspergillosis

Infections of the respiratory tract with fungi of the genus ASPERGILLUS.
