Abscess of lung with pneumonia

This code signifies a bacterial infection of the lung that has progressed to form a pus-filled cavity (abscess) within the lung tissue, occurring concurrently with inflammation of the lung (pneumonia). It represents a severe form of lung infection where both conditions are present.

Use this code when documentation clearly indicates the presence of both a lung abscess and pneumonia. This typically applies to patients presenting with symptoms such as fever, cough with purulent sputum, chest pain, and imaging (e.g., chest X-ray, CT scan) confirming both conditions.

• Ensure documentation explicitly states both "abscess" and "pneumonia" of the lung.
• Do not use this code if only a lung abscess or only pneumonia is documented; separate codes would apply.
• Consider sequencing this code as the primary diagnosis if it is the main reason for the encounter and treatment.
