K91.3Postprocedural intestinal obstruction

K91.3 is the ICD-10-CM diagnosis code for postprocedural intestinal obstruction. It belongs to category K91 (intraoperative and postprocedural complications and disorders of digestive system, not elsewhere classified), block K90-K95 (other diseases of the digestive system) and chapter 11 (diseases of the digestive system). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

Within K91 (intraoperative and postprocedural complications and disorders of digestive system, not elsewhere classified), K91.3 is specifically for postprocedural intestinal obstruction. Related codes cover vomiting following gastrointestinal surgery (K91.0), Postgastric surgery syndromes (K91.1), postsurgical malabsorption, not elsewhere classified (K91.2), Postcholecystectomy syndrome (K91.5), intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating a procedure (K91.6), accidental puncture and laceration of a digestive system organ or structure during a procedure (K91.7) and other intraoperative and postprocedural complications and disorders of digestive system (K91.8).

To report this condition, pick the subcode that matches the documentation: K91.30 (unspecified as to partial versus complete), K91.31 (obstruction) and K91.32 (obstruction).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2018 (expanded into subcodes).
