Pneumonia due to other specified bacteria

This code signifies pneumonia caused by a bacterial organism that is not otherwise specified or classified in more granular ICD-10-CM codes. It is used when the causative bacterium is identified and documented, but a more specific code for that particular bacterium's role in pneumonia does not exist.

Apply this code when documentation clearly states pneumonia due to a specific bacterium (e.g., Moraxella catarrhalis, Klebsiella pneumoniae, Pseudomonas aeruginosa) for which a dedicated ICD-10-CM code for pneumonia does not exist. This code requires definitive identification of the bacterial pathogen.

• Do not use this code for bacterial pneumonia where the specific bacterium is unknown or not documented; instead, consider J15.9 (Unspecified bacterial pneumonia).
• Ensure the medical record explicitly names the bacterial organism causing the pneumonia.
• Sequence this code as the primary diagnosis when pneumonia is the reason for the encounter, followed by codes for any associated conditions.
