Abscess of lung and mediastinum (J85)

The ICD-10 code section J85 is used to classify different types of abscesses occurring in the lung and mediastinum. These codes help specify whether the abscess is associated with pneumonia, necrosis, or isolated to lung or mediastinal tissues.

This section includes codes like J85.0 for cases involving lung gangrene and necrosis, which are also known as gangrenous pneumonia or pulmonary gangrene. The code J85.1 applies when a lung abscess occurs alongside pneumonia, sometimes referred to as confluent bronchopneumonia with abscess formation. For abscesses in the lung occurring without pneumonia, often called single or multiple lung abscesses or tuberculous abscesses, the appropriate code is J85.2. Additionally, J85.3 covers abscesses located specifically in the mediastinum, including those described as abscess of the wall of truncus arteriosus. These detailed codes enable accurate documentation and coding of complex infections affecting the respiratory and mediastinal regions, important for clinical, billing, and epidemiological purposes.
