Acute bronchitis due to Mycoplasma pneumoniae

This code signifies an acute inflammation of the bronchial tubes specifically caused by an infection with Mycoplasma pneumoniae. It represents a transient, self-limiting respiratory infection characterized by cough, fever, and sometimes wheezing, distinct from chronic bronchitis or other forms of pneumonia.

Apply this code when documentation clearly states a diagnosis of acute bronchitis and laboratory or clinical evidence confirms Mycoplasma pneumoniae as the causative agent. This is appropriate when the infection is primarily confined to the bronchi, without evidence of significant lung parenchymal involvement.

• Ensure the documentation explicitly links Mycoplasma pneumoniae as the etiology of the acute bronchitis.
• Do not use this code if the infection has progressed to pneumonia; instead, refer to codes in the J13-J18 range.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter.
