Which MS-DRGs does G11.11 group to?
G11.11 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.
- 058Multiple Sclerosis and Cerebellar Ataxia with MCCmedical
- 059Multiple Sclerosis and Cerebellar Ataxia with CCmedical
- 060Multiple Sclerosis and Cerebellar Ataxia without CC/MCCmedical
As a secondary diagnosis, G11.11 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
