About MS-DRG 059
MS-DRG 059, Multiple Sclerosis and Cerebellar Ataxia with CC, is a medical DRG in MDC 01 (Diseases and Disorders of the Nervous System) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.
Its FY2027 relative weight is 1.2002, so Medicare's base payment for this DRG is about 1.20 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 3.6 days and the arithmetic mean is 4.6 days.
It belongs to a 3-level severity family: DRG 058 (with MCC, weight 1.8438), DRG 059 (with CC, weight 1.2002) and DRG 060 (without CC/MCC, weight 0.9247). The highest-severity level carries 2.0 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
31 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
