Which MS-DRGs does B80 group to?
B80 sits in MDC 06 and helps define the logic of 2 MS-DRGs (version 44, FY2027). Which one a stay actually groups to also depends on procedures and secondary diagnoses.
- 391Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders with MCCmedical
- 392Esophagitis, Gastroenteritis and Miscellaneous Digestive Disorders without MCCmedical
As a secondary diagnosis, B80 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
