ICD-10 Code K57.93 – Diverticulitis of intestine, part unspecified, without perforation or abscess with bleeding (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K57.93 – Diverticulitis of intestine, part unspecified, without perforation or abscess with bleeding
What it is
This code identifies diverticulitis in an unspecified part of the intestine when bleeding is present, but there is no perforation or abscess. Use it when the record supports diverticulitis with hemorrhage and does not specify the bowel segment.
Clinical signs
Typical findings include abdominal pain with evidence of diverticular inflammation and gastrointestinal bleeding. Clinical features vary; refer to documentation for the affected site and confirmation that perforation or abscess is absent.
When to use this code
Use K57.93 when the provider documents diverticulitis with bleeding and does not identify the intestinal location. It also fits when imaging or assessment shows diverticulitis without perforation or abscess, but the note does not support a more specific site code.
Do not use for
Do not use this code if the record shows perforation, abscess, or a more specific intestinal location. Check documentation if the bleeding source is unclear or if diverticulosis is documented without diverticulitis.
Coding tip
Confirm both the bleeding and the absence of perforation or abscess before assigning K57.93.
