K26.0
ICD-10-CMThis code signifies an acutely developing ulceration in the duodenum, the first part of the small intestine, which is actively bleeding. The hemorrhage can manifest as hematemesis, melena, or hematochezia, indicating significant gastrointestinal blood loss originating from the ulcer site.
Apply this code when documentation clearly states an acute duodenal ulcer with evidence of active or recent hemorrhage. This includes findings from endoscopy (e.g., active oozing, visible vessel, adherent clot) or clinical signs of bleeding such such as a significant drop in hemoglobin/hematocrit alongside a confirmed duodenal ulcer.
