Code Classification

B44 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of aspergillosis. The code is not specific and is NOT valid for the year 2024 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding Applicable to Aspergillosis

Non-specific codes like B44 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10-CM codes with a higher level of specificity when coding for aspergillosis:

  • Use B44.0 for Invasive pulmonary aspergillosis - BILLABLE CODE

  • Use B44.1 for Other pulmonary aspergillosis - BILLABLE CODE

  • Use B44.2 for Tonsillar aspergillosis - BILLABLE CODE

  • Use B44.7 for Disseminated aspergillosis - BILLABLE CODE

  • B44.8 for Other forms of aspergillosis - NON-BILLABLE CODE

  • Use B44.81 for Allergic bronchopulmonary aspergillosis - BILLABLE CODE

  • Use B44.89 for Other forms of aspergillosis - BILLABLE CODE

  • Use B44.9 for Aspergillosis, unspecified - BILLABLE CODE

Clinical Information

  • 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.
  • 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. (from joynt, clinical neurology, 1998, ch 27, pp62-3)
  • Pulmonary Aspergillosis - infections of the respiratory tract with fungi of the genus aspergillus.
  • Aspergillus - a genus of mitosporic fungi containing about 100 species and eleven different teleomorphs in the family trichocomaceae.

Patient Education


Aspergillosis

Aspergillosis is a disease caused by a fungus (or mold) called Aspergillus. The fungus is very common in both indoors and outdoors. Most people breathe in the spores of the fungus every day without being affected. But some people get the disease. It usually occurs in people with lung diseases or weakened immune systems.

There are different kinds of aspergillosis. One kind is allergic bronchopulmonary aspergillosis (also called ABPA). Symptoms of ABPA include wheezing and coughing. ABPA can affect healthy people but it is most common in people with asthma or cystic fibrosis.

Another kind is invasive aspergillosis, which damages tissues in the body. It usually affects the lungs. Sometimes it can also cause infection in other organs and spread throughout the body. It affects people who have immune system problems, such as people who have had a transplant, are taking high doses of steroids, or getting chemotherapy for some cancers.

Your doctor might do a variety of tests to make the diagnosis, including a chest x-ray, CT scan of the lungs, and an examination of tissues for signs of the fungus. Treatment is with antifungal drugs. If you have ABPA, you may also take steroids.
