Laceration of duodenum, initial encounter

This diagnosis code signifies a tear or cut in the duodenum, the first part of the small intestine, that occurred recently and is being treated for the first time. Such an injury can range from a superficial tear to a full-thickness perforation, often resulting from trauma or iatrogenic causes.

Apply this code for patients presenting with a newly diagnosed laceration of the duodenum, such as those sustained from blunt or penetrating abdominal trauma, or as a complication during an endoscopic procedure. This code is appropriate for the initial visit or encounter where the injury is evaluated and definitive treatment is initiated.

• Ensure documentation clearly specifies a laceration of the duodenum, not just a general duodenal injury.
• Verify that the encounter is indeed the "initial encounter" for this specific injury. Subsequent care would require a different seventh character.
• Look for associated codes for the cause of the injury (e.g., external cause codes) to provide a complete clinical picture.
