Other intestinal Escherichia coli infections

This diagnosis code signifies an infection of the intestines caused by Escherichia coli strains other than those specifically classified elsewhere (e.g., enterohemorrhagic, enterotoxigenic, enteroinvasive, or enteropathogenic). It encompasses various less common pathogenic E. coli types that can lead to gastrointestinal symptoms.

Apply this code when documentation confirms an intestinal infection due to E. coli that is not specified as one of the more common pathogenic types. This typically requires laboratory confirmation identifying E. coli as the causative agent in a stool culture or other relevant specimen, without further strain-specific identification.

• Do not use this code if the E. coli strain is identified as enterohemorrhagic (EHEC), enterotoxigenic (ETEC), enteroinvasive (EIEC), or enteropathogenic (EPEC); specific codes exist for these.
• Ensure the documentation clearly states an intestinal infection and E. coli as the pathogen, without further specific classification.
• Always sequence this code after any underlying condition if the E. coli infection is a complication of another primary diagnosis.
