Pseudomonas (mallei) causing diseases classd elswhr

This code identifies Pseudomonas species, specifically P. aeruginosa, P. mallei, or P. pseudomallei, as the infectious agent responsible for a disease process. It is used when the primary condition caused by the Pseudomonas infection is classified under a different ICD-10-CM code. This indicates a secondary diagnosis, specifying the bacterial etiology.

Use this code as a secondary diagnosis when documentation clearly links a Pseudomonas infection to a primary condition, such as pneumonia, urinary tract infection, or sepsis, that has its own specific code. The medical record must explicitly state Pseudomonas as the causative organism for the primary disease.

• Always sequence this code after the primary diagnosis code that describes the manifestation of the Pseudomonas infection.
• Ensure the documentation specifies Pseudomonas as the causative agent, not just a positive culture without clinical significance.
• Do not use this code if the Pseudomonas infection is the primary diagnosis and there is a specific code for that condition (e.g., certain types of pneumonia directly linked to Pseudomonas).
