Intestinal infection due to arizona group of paracolon bacilli

This code represents an intestinal infection specifically caused by bacteria from the Arizona group of paracolon bacilli. It indicates a bacterial gastroenteritis or enterocolitis where the causative organism has been identified as belonging to this particular serogroup.

Use this code when documentation clearly specifies an intestinal infection due to "Arizona group of paracolon bacilli" or similar terminology. This typically follows laboratory confirmation of the causative agent from stool cultures or other relevant specimens.

• Ensure the documentation explicitly names "Arizona group of paracolon bacilli" as the etiology; do not assume based on general symptoms.
• Distinguish from other specified or unspecified bacterial intestinal infections if the specific organism is not documented as Arizona group.
• Sequence as the primary diagnosis when this infection is the reason for the encounter.
