Abscess of intestine

This code signifies a localized collection of pus within the intestinal wall or adjacent to it, resulting from an infection. It represents an inflammatory process leading to tissue necrosis and purulent exudate formation within the bowel.

Apply this code when documentation explicitly states an "abscess of the intestine," "intestinal abscess," or "bowel abscess." This diagnosis is typically supported by imaging studies (e.g., CT scan, ultrasound) confirming a contained purulent collection within or immediately surrounding the intestinal tract.

• Differentiate from peritonitis or other generalized intra-abdominal infections; this code specifies a localized abscess.
• Look for documentation specifying the exact anatomical location within the intestine if available, though this code is general.
• Consider sequencing this code after the underlying cause of the abscess, if known and documented (e.g., diverticulitis with abscess).
