Which MS-DRGs does G93.45 group to?
G93.45 sits in MDC 01 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.
- 070Other Cerebrovascular Disorders with MCCmedical
- 071Other Cerebrovascular Disorders with CCmedical
- 072Other Cerebrovascular Disorders without CC/MCCmedical
As a secondary diagnosis, G93.45 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
