Pneumonia due to Acinetobacter baumannii

This diagnosis code identifies pneumonia specifically caused by the bacterium Acinetobacter baumannii. This type of pneumonia is often severe, can be hospital-acquired, and is frequently associated with antibiotic resistance. It represents an infection of the lung parenchyma due to this particular bacterial pathogen.

Use this code when documentation clearly states a diagnosis of pneumonia and laboratory cultures or other diagnostic tests confirm Acinetobacter baumannii as the causative organism. This is commonly seen in critically ill patients, those on ventilators, or individuals with compromised immune systems.

• Always ensure the documentation explicitly links Acinetobacter baumannii as the etiology of the pneumonia.
• Do not use this code if the organism is identified as Acinetobacter species without further specification of baumannii.
• Consider co-morbid conditions and other infections that may be present and require additional coding.
