Acute bronchiolitis due to other specified organisms

This code signifies an acute inflammation of the small airways (bronchioles) of the lungs, specifically when the causative agent is an organism other than Respiratory Syncytial Virus (RSV) or metapneumovirus. It represents a severe lower respiratory tract infection primarily affecting infants and young children, leading to wheezing, coughing, and difficulty breathing.

Apply this code when documentation clearly indicates acute bronchiolitis and specifies a non-RSV, non-metapneumovirus infectious etiology, such as adenovirus, influenza virus, or parainfluenza virus. This code is appropriate when the specific organism is identified and falls outside the scope of other specified bronchiolitis codes.

• Ensure the documentation explicitly states "acute bronchiolitis" and identifies a specific organism that is not RSV or metapneumovirus.
• Do not use this code if the organism is unspecified; instead, consider codes for acute bronchiolitis due to unspecified organism.
• Sequence this code as the primary diagnosis when it is the reason for the encounter, followed by codes for any associated symptoms or complications.
