Bronchiectasis with (acute) exacerbation

This code signifies a chronic, irreversible dilation of the bronchi and bronchioles, characterized by episodes of worsening respiratory symptoms such as increased cough, sputum production, and dyspnea. These exacerbations often involve bacterial infections and lead to further lung damage.

Apply this code when documentation clearly indicates a patient with pre-existing bronchiectasis is experiencing an acute worsening of their condition. Supporting documentation includes physician notes detailing increased respiratory symptoms, changes in sputum, and/or evidence of infection requiring intervention.

• Ensure the documentation explicitly states "with exacerbation" or describes an acute worsening of symptoms in a patient with known bronchiectasis.
• Do not use this code for stable, non-exacerbated bronchiectasis; use J47.9 in such cases.
• Sequence this code as the primary diagnosis when the exacerbation is the reason for the encounter, followed by codes for any identified infectious agents.
