Which MS-DRGs does G37.5 group to?

G37.5 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, G37.5 is a complication or comorbidity (CC), which can move a stay into a higher-paying DRG.

How is G37.5 listed in the Alphabetic Index?

Excludes2 — not included here — inherited from Chapter 6

The conditions below are not part of G37.5, but a patient may have both at the same time. When documentation supports it, G37.5 and the excluded code may both be reported.

  • certain conditions originating in the perinatal period (P04-P96)
  • certain infectious and parasitic diseases (A00-B99)
  • complications of pregnancy, childbirth and the puerperium (O00-O9A)
  • congenital malformations, deformations, and chromosomal abnormalities (Q00-Q99)
  • endocrine, nutritional and metabolic diseases (E00-E88)
  • injury, poisoning and certain other consequences of external causes (S00-T88)
  • neoplasms (C00-D49)
  • symptoms, signs and abnormal clinical and laboratory findings, not elsewhere classified (R00-R94)
