Bronchiectasis with acute exacerbation

This code signifies a chronic, irreversible dilation of the bronchi and bronchioles, which has recently worsened. The patient is experiencing an acute flare-up of their underlying bronchiectasis, characterized by increased symptoms such as cough, sputum production, and shortness of breath.

Apply this code when documentation clearly indicates a pre-existing diagnosis of bronchiectasis and a current episode of acute exacerbation. This is typically supported by physician notes detailing a change in baseline respiratory symptoms requiring intervention.

• Ensure documentation explicitly states "acute exacerbation" or similar phrasing indicating a worsening of the chronic condition.
• Do not use this code for uncomplicated bronchiectasis; a separate code exists for that.
• Consider co-reporting with codes for infectious agents if identified as the cause of the exacerbation.
