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

This code describes inflammation of diverticula in the large intestine that is complicated by bleeding, but without evidence of a perforation or abscess. It indicates an acute or chronic inflammatory process within the colonic diverticula, presenting with gastrointestinal hemorrhage.

Apply this code when documentation specifies diverticulitis of the large intestine with associated bleeding, and explicitly states the absence of perforation or abscess. This is appropriate for patients presenting with lower GI bleeding attributed to diverticular disease, confirmed by endoscopy or imaging, where no other severe complications are noted.

• Ensure documentation clearly states "without perforation or abscess" to avoid miscoding to more severe forms.
• Distinguish from diverticulosis with bleeding (K57.5x) where inflammation is not present.
• Sequence this code as the primary diagnosis when the diverticulitis with bleeding is the reason for the encounter.
