Intestinal infection due to aerobacter aerogenes

This code describes an intestinal infection specifically caused by Aerobacter aerogenes, a gram-negative bacterium. It indicates a bacterial enteritis or gastroenteritis where the causative organism has been identified through laboratory testing.

Apply this code when documentation clearly specifies an intestinal infection and microbiological culture results confirm Aerobacter aerogenes as the etiologic agent. This is typically seen in cases of acute gastroenteritis with identified bacterial pathogens.

• Ensure the physician documentation explicitly names Aerobacter aerogenes as the pathogen.
• Do not use for unspecified bacterial intestinal infections; a more general code would be appropriate if the specific organism is not documented.
• Sequence as the primary diagnosis when the intestinal infection is the reason for the encounter.
