About coding Postcholecystectomy syndrome
The ICD-10-CM code for Postcholecystectomy syndrome is K91.5 (Postcholecystectomy syndrome).
Within K91 (intraoperative and postprocedural complications and disorders of digestive system, not elsewhere classified), K91.5 is specifically for Postcholecystectomy syndrome. Related codes cover vomiting following gastrointestinal surgery (K91.0), Postgastric surgery syndromes (K91.1), postsurgical malabsorption, not elsewhere classified (K91.2), postprocedural intestinal obstruction (K91.3), 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).
It is not a CC or MCC, so as a secondary diagnosis it doesn't change the MS-DRG severity level.
In MS-DRG v44.0, it is part of the grouping logic for DRG 444 (Disorders of the Biliary Tract with MCC, relative weight 1.6665), DRG 445 (Disorders of the Biliary Tract with CC, relative weight 1.0872) and DRG 446 (Disorders of the Biliary Tract without CC/MCC, relative weight 0.8124), in MDC 07 (Diseases and Disorders of the Hepatobiliary System and Pancreas), as a principal or secondary diagnosis. The DRG a claim lands in depends on the principal diagnosis, procedures and any CC/MCC secondary diagnoses.
