About MS-DRG 094
MS-DRG 094, Bacterial and Tuberculous Infections of Nervous System with MCC, 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 3.4124, so Medicare's base payment for this DRG is about 3.41 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 7.7 days and the arithmetic mean is 10.2 days.
It belongs to a 3-level severity family: DRG 094 (with MCC, weight 3.4124), DRG 095 (with CC, weight 2.3492) and DRG 096 (without CC/MCC, weight 2.3213). The highest-severity level carries 1.5 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
