Pneumonia due to Klebsiella pneumoniae

This diagnosis code identifies pneumonia specifically caused by the bacterium Klebsiella pneumoniae. It indicates an acute inflammatory condition of the lung parenchyma resulting from infection by this particular gram-negative bacillus. Patients typically present with symptoms such as fever, cough, dyspnea, and often a characteristic "currant jelly" sputum.

Apply this code when documentation clearly states pneumonia due to Klebsiella pneumoniae. This often follows positive sputum cultures, blood cultures, or other microbiological tests confirming the presence of Klebsiella pneumoniae as the causative agent of the pneumonia. Use this code when the organism is explicitly identified.

• Ensure the documentation explicitly links Klebsiella pneumoniae as the etiologic agent of the pneumonia; do not assume based on clinical presentation alone.
• Do not use this code for unspecified bacterial pneumonia or pneumonia where the specific organism is not identified.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter, followed by any associated complications.
