Enteropathogenic Escherichia coli infection

This code identifies an intestinal infection caused by specific strains of Escherichia coli that adhere to the intestinal lining, leading to diarrheal illness. It is characterized by the colonization of the small intestine by enteropathogenic E. coli (EPEC) without toxin production or invasion.

Assign this code when documentation explicitly states a diagnosis of enteropathogenic E. coli infection. This typically applies to cases of acute gastroenteritis where laboratory confirmation identifies EPEC as the causative agent.

• Ensure documentation specifies "enteropathogenic" E. coli to differentiate from other E. coli infections.
• Do not confuse with other E. coli infections like enterohemorrhagic (EHEC), enterotoxigenic (ETEC), or enteroinvasive (EIEC).
• Code any associated symptoms, such as dehydration or abdominal pain, as secondary diagnoses.
