ICD-10 Code K57.92 – Diverticulitis of intestine, part unspecified, without perforation or abscess without bleeding (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code K57.92 – Diverticulitis of intestine, part unspecified, without perforation or abscess without bleeding
What it is
K57.92 identifies diverticulitis when the affected intestinal segment is not specified and there is no documented perforation, abscess, or bleeding. Use it for uncomplicated diverticular inflammation when the record does not name a more exact site.
Clinical signs
Typical findings include localized abdominal pain, tenderness, and signs of intestinal inflammation. Clinical features vary; refer to documentation, and confirm that perforation, abscess, or bleeding are not present.
When to use this code
Use this code when the provider documents diverticulitis of the intestine but does not specify the part involved. It also fits cases described as uncomplicated, without perforation, abscess, or bleeding. If the note names a specific bowel segment, code that more precise option instead.
Do not use for
Do not use K57.92 if the record documents perforation, abscess, or bleeding, because those require different codes. Also avoid it when the provider identifies a specific intestinal location and a more detailed code is available.
Coding tip
Check the documentation for site and complication status before assigning K57.92.
