  • K91.0 Vomiting following gastrointestinal surgery
  • K91.1 Postgastric surgery syndromes
  • K91.2 Postsurgical malabsorption, not elsewhere classified
  • K91.3 Postprocedural intestinal obstruction (also a header)

  • K91.8 Other intraoperative and postprocedural complications and disorders of digestive system (also a header)
