A04.72

What This Code Means

This code describes an infection of the colon and small intestine caused by Clostridium difficile bacteria, which typically occurs after antibiotic use. It is used when the infection is occurring for the first time or when it is not documented as a recurring episode.

Coding Tips

• •Verify documentation does not indicate recurrent C. difficile infection; if recurrent, use A04.71 instead
• •This code is commonly associated with recent antibiotic therapy—review clinical notes for context and consider documenting the triggering antibiotic if present
