About MS-DRG 305
MS-DRG 305, Hypertension without MCC, is a medical DRG in MDC 05 (Diseases and Disorders of the Circulatory 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 0.7581, so Medicare's base payment for this DRG is about 0.76 times the average inpatient case (below average), before hospital-specific adjustments. The geometric mean length of stay is 2.1 days and the arithmetic mean is 2.6 days.
It belongs to a 2-level severity family: DRG 304 (with MCC, weight 1.2011) and DRG 305 (without MCC, weight 0.7581). The highest-severity level carries 1.6 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
