Acute bronchiolitis due to human metapneumovirus
ICD-10 J21.1 is a billable code used to indicate a diagnosis of acute bronchiolitis due to human metapneumovirus.
Acute bronchiolitis due to human metapneumovirus (hMPV) is a viral infection primarily affecting infants and young children, characterized by inflammation of the bronchioles, the small air passages in the lungs. Clinically, it presents with symptoms such as wheezing, coughing, shortness of breath, and respiratory distress. The condition typically follows a viral upper respiratory infection, with hMPV being one of the common pathogens involved. The anatomy affected includes the bronchioles, which become obstructed due to inflammation and mucus production, leading to impaired airflow and gas exchange. Disease progression can vary, with some patients experiencing mild symptoms while others may develop severe respiratory distress requiring hospitalization. Diagnostic considerations include a thorough clinical evaluation, history of exposure to respiratory infections, and, in some cases, laboratory testing such as PCR to confirm hMPV infection. Understanding the clinical presentation and progression is crucial for timely intervention and management of this condition.

J21.1 specifically covers acute bronchiolitis caused by human metapneumovirus. It is characterized by acute inflammation of the bronchioles and is typically seen in infants and young children, often following a viral upper respiratory infection.
J21.1 should be used when the clinical presentation of acute bronchiolitis is confirmed to be due to human metapneumovirus, differentiating it from other viral causes such as respiratory syncytial virus (J21.0) or unspecified bronchiolitis (J21.9).
Documentation for J21.1 should include a detailed clinical history, physical examination findings, symptomatology, and any laboratory results confirming the presence of human metapneumovirus. Clear notes on the patient's respiratory status and treatment response are also essential.
