About K91.8
K91.8 is the ICD-10-CM diagnosis code for other intraoperative and postprocedural complications and disorders of digestive system. 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 8 subcodes must be used instead.
Within K91, choose K91.8 (Other intraoperative and postprocedural complications and disorders of digestive system) only when documentation doesn't support a more specific option: vomiting following gastrointestinal surgery (K91.0), Postgastric surgery syndromes (K91.1), postsurgical malabsorption, not elsewhere classified (K91.2), postprocedural intestinal obstruction (K91.3), Postcholecystectomy syndrome (K91.5), intraoperative hemorrhage and hematoma of a digestive system organ or structure complicating a procedure (K91.6) and accidental puncture and laceration of a digestive system organ or structure during a procedure (K91.7).
To report this condition, pick the subcode that matches the documentation: K91.81 (system), K91.82 (failure), K91.83 (syndrome), K91.84 (procedure), K91.85 (pouch), K91.86 (cholecystectomy), K91.87 (procedure) and K91.89 (system).
It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
