Dvtrcli of both small and lg int w perf and abscs w/o bleed

This code signifies inflammation of diverticula affecting both the small and large intestines, complicated by a perforation and localized collection of pus (abscess). Importantly, there is no evidence of gastrointestinal bleeding associated with this condition.

Apply this code when documentation explicitly states diverticulitis involving both the small and large bowel, accompanied by both perforation and abscess formation. The absence of active bleeding must also be clearly indicated in the patient's record.

• Ensure documentation specifies involvement of both small and large intestines.
• Verify the presence of both perforation and abscess; if only one is present, a different code is required.
• Confirm the absence of bleeding; if bleeding is present, a different code from the K57.4 series would be appropriate.
