MS-DRG 656: KIDNEY AND URETER PROCEDURES FOR NEOPLASM WITH MCC
MS-DRG 656 is kidney and ureter procedures for neoplasm with mcc, in MDC 11 (a surgical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 3.2786, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 4.90 days. 67 ICD-10-CM principal diagnoses group into MS-DRGs 656–658 under the CMS definitions manual; the most-searched are listed below.
