Dvtrcli of lg int w perforation and abscess w/o bleeding

This code represents an acute or chronic inflammation of diverticula in the large intestine that has progressed to include both a perforation (a hole or tear) in the bowel wall and the formation of an abscess (a localized collection of pus). Importantly, this specific diagnosis indicates the absence of any associated gastrointestinal bleeding.

Use this code when documentation clearly states diverticulitis of the large intestine with evidence of both perforation and abscess formation. This typically occurs in patients presenting with severe abdominal pain, fever, and signs of peritonitis or a palpable mass. Supporting documentation would include imaging reports (e.g., CT scan) confirming perforation and abscess, and operative reports if surgical intervention occurred.

• Ensure documentation explicitly states both perforation and abscess; if only one is present, a different code is required.
• Verify the absence of bleeding; if bleeding is present, a different subcategory of K57.2 would be appropriate.
• Always sequence this code as the primary diagnosis when it is the reason for the encounter, unless another condition is clearly identified as the principal diagnosis requiring treatment.
