About coding lung gangrene
The ICD-10-CM code for lung gangrene is J85.0 (Gangrene and necrosis of lung). The official index lists 1 more specific code, so check the documentation for details such as type, cause, site or severity before settling on J85.0.
Within J85 (abscess of lung and mediastinum), J85.0 is specifically for gangrene and necrosis of lung. Related codes cover abscess of lung with pneumonia (J85.1), abscess of lung without pneumonia (J85.2) and abscess of mediastinum (J85.3).
Use an additional code (B95-B97) to identify infectious agent.
As a secondary diagnosis it is an MCC (major complication or comorbidity), which can move an inpatient stay into the highest-paying "with MCC" MS-DRG of its family, unless the principal diagnosis excludes it.
