Enterocolitis due to Clostridium difficile, recurrent

This code signifies an inflammation of both the small and large intestines caused by the bacterium Clostridioides difficile (formerly Clostridium difficile), which has re-emerged after a period of resolution. It indicates a subsequent episode of C. difficile infection following successful treatment of a prior infection.

Use this code when documentation explicitly states a diagnosis of recurrent C. difficile enterocolitis. This typically applies to patients who have experienced a previous episode of C. difficile infection, were treated, and are now presenting with new symptoms and a positive test for C. difficile or its toxins.

• Ensure documentation clearly specifies "recurrent" to differentiate from an initial episode.
• Do not use this code for a new C. difficile infection in a patient with no prior history.
• Consider sequencing this code as the primary diagnosis if it is the reason for the encounter.
