Abscess of intestine

This code represents a localized collection of pus within the wall or lumen of any part of the intestine, excluding the appendix, anal, and rectal regions. This infection typically results from bacterial invasion and can lead to significant inflammation and systemic symptoms.

Use this code when documentation explicitly states "abscess of intestine" without further specification of an underlying inflammatory bowel disease or diverticular disease. This diagnosis is often supported by imaging studies (e.g., CT scan, MRI) confirming the presence of an intra-abdominal abscess originating from the bowel.

• Always review documentation for underlying conditions like Crohn's disease, ulcerative colitis, or diverticular disease, as these require different codes.
• Distinguish from perianal or rectal abscesses, which are classified under K61.-.
• Ensure the abscess is specifically intestinal and not appendiceal (K35.3-).
