Abscess of lung

This code signifies a localized collection of pus within the lung parenchyma, typically resulting from bacterial infection. It represents a destructive process forming a cavity in the lung tissue.

This code is appropriate for documented cases of pulmonary abscess, often identified through imaging studies like chest X-ray or CT scan, and confirmed by clinical signs of infection and sometimes sputum culture. Documentation should clearly state "lung abscess" or "pulmonary abscess."

• Differentiate from empyema (pus in the pleural space), which is coded separately.
• Specify the underlying cause if known and documented (e.g., aspiration pneumonia, bacterial infection) by coding it as a secondary diagnosis.
• Ensure documentation distinguishes between acute and chronic lung abscess if applicable, as this code does not differentiate.
