About MS-DRG 081
MS-DRG 081, Nontraumatic Stupor and Coma without 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 0.806, so Medicare's base payment for this DRG is about 0.81 times the average inpatient case (below average), before hospital-specific adjustments. The geometric mean length of stay is 2.8 days and the arithmetic mean is 3.5 days.
It belongs to a 2-level severity family: DRG 080 (with MCC, weight 1.7472) and DRG 081 (without MCC, weight 0.806). The highest-severity level carries 2.2 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
44 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
