ICD Code K57.80

ICD code K57.80 is diverticulitis of the intestine, where the specific part of the intestine is not specified, and it is complicated by both a perforation (a hole or tear) and an abscess (a collection of pus), but there is no associated bleeding.

1. Patient presents with clinical signs and symptoms consistent with diverticulitis, such as lower abdominal pain, fever, and leukocytosis.

2. Imaging studies (e.g., CT scan, ultrasound) confirm the presence of diverticulitis in the intestine, but the specific part of the intestine is not identified.

3. Evidence of perforation of the intestinal wall is present, as indicated by free air, localized or generalized peritonitis, or extraluminal contrast on imaging.

4. Abscess formation is identified, either clinically or radiologically, in association with the diverticulitis.

5. There is no evidence of gastrointestinal bleeding associated with the diverticulitis episode.
