Cntct w and expsr to intestnl infct dis d/t E coli (E. coli)

This code indicates that an individual has had contact with, or is suspected of having been exposed to, an intestinal infectious disease caused by Escherichia coli (E. coli). This is a prophylactic or surveillance code, used when the patient is not currently exhibiting symptoms of an active E. coli infection but has a known or suspected exposure event.

This code is appropriate for documenting exposure to E. coli, such as after consuming contaminated food or water, or close contact with an infected individual. It is used when the patient is asymptomatic but requires monitoring or prophylactic treatment due to the exposure.

• Do not use this code if the patient has a confirmed active E. coli infection; instead, code the specific E. coli infection.
• This code can be used as a primary or secondary diagnosis, depending on the reason for the encounter.
• Consider adding an additional code for the specific type of exposure (e.g., foodborne, waterborne) if known and supported by documentation.
