Z20.01

Billable

Contact with and (suspected) exposure to intestinal infectious diseases due to Escherichia coli (E. coli)

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

What This Code Means

A person has been exposed to or had contact with someone who has an E. coli intestinal infection.

Coding Tips

  • This is a contact/exposure code, not a diagnosis of active infection; use when the patient is asymptomatic but exposed
  • Specify the source of exposure (family member, workplace, etc.) in documentation to support public health tracking
