Its FY2027 relative weight is 1.5842, so Medicare's base payment for this DRG is about 1.58 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 1.5 days and the arithmetic mean is 1.8 days.
It belongs to a 3-level severity family: DRG 619 (with MCC, weight 2.5987), DRG 620 (with CC, weight 1.5842) and DRG 621 (without CC/MCC, weight 1.5622). The highest-severity level carries 1.7 times the weight of the lowest, which is why documenting CC and MCC conditions matters.
