Friedl�nder's bacillus infection in conditions classified elsewhere and of unspecified site

This code indicates an infection caused by Klebsiella pneumoniae (Friedländer's bacillus) when the primary condition or site of infection is classified elsewhere or is not specified. It signifies the presence of this specific bacterial pathogen contributing to an underlying disease process.

Use this code when documentation confirms a Klebsiella pneumoniae infection, but the specific anatomical site of the infection is not clearly identified, or the infection is secondary to another condition coded elsewhere. This is often seen in cases of bacteremia or sepsis where the source is unknown, or when the infection is a complication of another primary diagnosis.

• Always sequence this code after the primary condition or manifestation of the infection, if known.
• Ensure documentation explicitly mentions "Friedländer's bacillus" or "Klebsiella pneumoniae" as the causative organism.
• Avoid using this code if a more specific site-specific Klebsiella infection code (e.g., pneumonia, UTI) is available and documented.
