Diverticulitis of large intestine with perforation and abscess with bleeding
ICD-10 K57.21 is a billable code used to indicate a diagnosis of diverticulitis of large intestine with perforation and abscess with bleeding.
Diverticulitis of the large intestine with perforation and abscess with bleeding is a severe complication of diverticular disease, characterized by inflammation and infection of diverticula, which are small pouches that can form in the walls of the colon. Clinically, patients may present with acute abdominal pain, fever, and changes in bowel habits, often accompanied by gastrointestinal bleeding. The anatomy involved primarily includes the sigmoid colon, where diverticula are most commonly located. Disease progression can lead to perforation of the diverticulum, resulting in peritonitis and the formation of abscesses, which may further complicate the clinical picture. Diagnostic considerations include imaging studies such as CT scans to confirm the presence of diverticulitis, abscess formation, and any associated complications. Laboratory tests may reveal leukocytosis and signs of infection. Early diagnosis and intervention are critical to prevent serious complications, including sepsis and significant morbidity.

K57.21 covers diverticulitis of the large intestine that is complicated by perforation, abscess formation, and associated bleeding. It is important to document the presence of these complications to justify the use of this specific code.
K57.21 should be used when there is clear evidence of diverticulitis with perforation and abscess formation, along with bleeding. If these complications are not present, other codes such as K57.20 should be considered.
Documentation should include clinical findings, imaging results (such as CT scans), laboratory tests indicating infection, and a clear treatment plan that addresses the complications of diverticulitis.
