Crohn's disease of large intestine with abscess

This code identifies a specific manifestation of Crohn's disease, an inflammatory bowel condition, affecting the large intestine. The key feature is the presence of an abscess, a localized collection of pus, within or adjacent to the large bowel in a patient with Crohn's.

Apply this code when documentation clearly indicates Crohn's disease localized to the large intestine, along with a confirmed abscess. This typically requires imaging reports (e.g., CT, MRI) or surgical findings detailing the abscess, in addition to endoscopic or biopsy confirmation of Crohn's in the colon.

• Always confirm the specific anatomical site of Crohn's (large intestine) and the presence of an abscess.
• Do not use if the abscess is unrelated to the Crohn's disease or if the Crohn's affects other parts of the GI tract without large intestine involvement.
• Consider additional codes for complications related to the abscess (e.g., fistula, perforation) if documented.
