Intestinal infection due to proteus (mirabilis) (morganii)

This code signifies an intestinal infection specifically caused by Proteus species, such as P. mirabilis or P. morganii. It describes a bacterial enteritis or colitis where the causative organism has been identified as Proteus.

Apply this code when documentation explicitly states an intestinal infection due to Proteus, confirmed by laboratory findings (e.g., stool culture). This is appropriate for cases of gastroenteritis or colitis where Proteus is identified as the pathogen.

• Ensure the documentation specifies an intestinal infection, not a urinary tract or other site infection.
• Verify that Proteus is the identified causative organism; do not use for unspecified bacterial enteritis.
• Consider an additional code for dehydration if present and documented.
