What This Code Means

Salmonella enteritis is a bacterial infection of the small intestine caused by Salmonella bacteria, typically resulting in diarrhea, abdominal cramps, and fever. This condition is usually acquired through contaminated food or water.

Coding Tips

• •Verify the documentation specifies Salmonella enteritis rather than other forms of salmonellosis (such as typhoid fever or septicemia), as each has a different ICD-10-CM code
• •Document the source of infection if known (food, water, animal contact) as this may support medical necessity and help with public health reporting
