Which MS-DRGs does K68.2 group to?
K68.2 sits in MDC 06 and helps define the logic of 3 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 371Major Gastrointestinal Disorders and Peritoneal Infections with MCCmedical
- 372Major Gastrointestinal Disorders and Peritoneal Infections with CCmedical
- 373Major Gastrointestinal Disorders and Peritoneal Infections without CC/MCCmedical
As a secondary diagnosis, K68.2 is a major complication or comorbidity (MCC), which can move a stay into a higher-paying DRG.
