About MS-DRG 673
MS-DRG 673, Other Kidney and Urinary Tract Procedures with MCC, is a surgical DRG in MDC 11 (Diseases and Disorders of the Kidney and Urinary Tract) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.
Its FY2027 relative weight is 4.2525, so Medicare's base payment for this DRG is about 4.25 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 10 days and the arithmetic mean is 13 days.
It belongs to a 3-level severity family: DRG 673 (with MCC, weight 4.2525), DRG 674 (with CC, weight 2.2504) and DRG 675 (without CC/MCC, weight 1.5887). The highest-severity level carries 2.7 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
