Pneumonia due to Klebsiella pneumoniae

This code represents an acute inflammatory condition of the lung parenchyma specifically caused by the bacterium Klebsiella pneumoniae. It involves infection and inflammation of the alveoli and bronchioles, leading to impaired gas exchange. Patients typically present with symptoms such as fever, cough, dyspnea, and chest pain.

Assign this code when documentation clearly identifies pneumonia and specifies Klebsiella pneumoniae as the causative organism. This often requires laboratory confirmation, such as a positive sputum culture or blood culture. It is appropriate for both community-acquired and healthcare-associated Klebsiella pneumonia.

• Ensure the documentation explicitly states "pneumonia" and "Klebsiella pneumoniae" as the etiology.
• Do not use this code for unspecified bacterial pneumonia; a more specific code should be sought if the organism is known.
• Consider sequencing this code as the principal diagnosis if it is the primary reason for the encounter, followed by any associated complications.
