About coding pulmonary necrosis
The ICD-10-CM code for pulmonary necrosis is J85.0 (Gangrene and necrosis of lung).
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.
