Enterotoxigenic Escherichia coli infection

This code does not map to an HCC category in any model (V28, V24, ESRD, RxHCC).

What This Code Means

This is a bacterial infection caused by a specific type of E. coli bacteria that produces toxins affecting the intestines, typically causing diarrhea and abdominal discomfort. It is commonly acquired through contaminated food or water.

Coding Tips

  • Verify documentation specifies enterotoxigenic E. coli (ETEC) rather than other pathogenic E. coli strains, as different codes apply to different types
  • Document the site of infection (intestinal) and any associated symptoms like diarrhea to support medical necessity and severity assessment
