K91.85Complications of intestinal pouch

K91.85 is the ICD-10-CM diagnosis code for complications of intestinal pouch. 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 2 subcodes must be used instead.

Within K91.8 (other intraoperative and postprocedural complications and disorders of digestive system), K91.85 is specifically for complications of intestinal pouch. Related codes cover other intraoperative complications of digestive system (K91.81), postprocedural hepatic failure (K91.82), postprocedural hepatorenal syndrome (K91.83), postprocedural hemorrhage of a digestive system organ or structure following a procedure (K91.84), retained cholelithiasis following cholecystectomy (K91.86), postprocedural hematoma and seroma of a digestive system organ or structure following a procedure (K91.87) and other postprocedural complications and disorders of digestive system (K91.89).

To report this condition, pick the subcode that matches the documentation: K91.850 (Pouchitis) and K91.858 (pouch).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
