Which MS-DRGs does G11.0 group to?

G11.0 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, G11.0 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.
