Acute bronchitis due to echovirus

This code signifies an acute inflammation of the bronchial tubes caused specifically by an echovirus infection. Patients typically present with symptoms such as cough, wheezing, and shortness of breath, which are characteristic of acute bronchitis, with the underlying etiology confirmed as echovirus.

Assign this code when medical record documentation clearly states a diagnosis of acute bronchitis and explicitly identifies echovirus as the causative agent. This typically requires laboratory confirmation of echovirus or a physician's definitive clinical diagnosis based on epidemiological factors and symptom presentation.

• Ensure documentation specifies "acute" bronchitis; chronic bronchitis due to echovirus would be coded differently.
• Confirm the viral etiology is explicitly stated as echovirus, not just "viral bronchitis" or "other specified virus."
• Do not use this code if the bronchitis is due to a different specified virus or if the viral agent is unspecified.
