Other injury of duodenum, sequela

This code signifies a long-term complication or late effect resulting from a previous injury to the duodenum, which is the first part of the small intestine. These sequelae can manifest months or even years after the initial trauma has healed, impacting the duodenum's structure or function.

This code is appropriate when documenting conditions such as chronic strictures, adhesions, fistulas, or malabsorption syndromes that are directly attributable to a past duodenal injury. It should be used when the acute phase of the original injury has resolved, and the patient is presenting with persistent or new problems stemming from that prior event.

• Always sequence this sequela code after the code for the specific manifestation of the sequela (e.g., K31.5 for duodenal obstruction).
• Ensure documentation clearly links the current condition to a previous duodenal injury, specifying the nature of the original trauma if possible.
• Do not use this code for acute or current duodenal injuries; those require codes from the S36.4 category without the "S" seventh character.
