About MS-DRG 538
MS-DRG 538, Sprains, Strains, and Dislocations of Hip, Pelvis and Thigh without CC/MCC, is a medical DRG in MDC 08 (Diseases and Disorders of the Musculoskeletal System and Connective Tissue) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.
Its FY2027 relative weight is 0.7109, so Medicare's base payment for this DRG is about 0.71 times the average inpatient case (below average), before hospital-specific adjustments. The geometric mean length of stay is 2.4 days and the arithmetic mean is 2.8 days.
It belongs to a 2-level severity family: DRG 537 (with CC/MCC, weight 0.9152) and DRG 538 (without CC/MCC, weight 0.7109). The highest-severity level carries 1.3 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
61 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
