Bronchiolitis obliterans and bronchiolitis obliterans syndrome
ICD-10 J44.81 is a billable code used to indicate a diagnosis of bronchiolitis obliterans and bronchiolitis obliterans syndrome.
Bronchiolitis obliterans (BO) and bronchiolitis obliterans syndrome (BOS) are serious respiratory conditions characterized by the obstruction of the small airways (bronchioles) due to inflammation and scarring. Clinically, patients may present with progressive dyspnea, cough, and wheezing, often following a viral infection, exposure to toxic substances, or as a complication of lung transplantation. The anatomy involved includes the bronchioles, which are the smallest air passages in the lungs, leading to the alveoli where gas exchange occurs. Disease progression can lead to significant respiratory compromise and may result in pulmonary fibrosis. Diagnostic considerations include pulmonary function tests (PFTs) that reveal obstructive patterns, high-resolution computed tomography (HRCT) scans showing airway changes, and sometimes lung biopsies. Early diagnosis is crucial for management, which may involve corticosteroids, immunosuppressive therapy, or lung transplantation in severe cases.

J44.81 encompasses bronchiolitis obliterans and bronchiolitis obliterans syndrome, which are characterized by the obstruction of the bronchioles due to inflammation and fibrosis. These conditions may arise from various etiologies, including post-infectious processes, exposure to environmental toxins, or as a complication of lung transplantation.
J44.81 should be used when the clinical presentation aligns specifically with bronchiolitis obliterans or bronchiolitis obliterans syndrome, particularly when there is evidence of airway obstruction and associated symptoms. It is important to differentiate it from other chronic obstructive pulmonary diseases that do not involve the same pathophysiological changes.
Documentation for J44.81 should include clinical notes detailing the patient's symptoms, diagnostic imaging results, pulmonary function test results, and any relevant history of lung transplantation or exposure to known risk factors. Comprehensive documentation of treatment plans and responses is also critical.
