Which MS-DRGs does K40.30 group to?
K40.30 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.
- 393Other Digestive System Diagnoses with MCCmedical
- 394Other Digestive System Diagnoses with CCmedical
- 395Other Digestive System Diagnoses without CC/MCCmedical
As a secondary diagnosis, K40.30 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
