MS-DRG 374 is digestive malignancy with mcc, in MDC 06 (a medical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 2.1109, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 5.40 days. 93 ICD-10-CM principal diagnoses group into MS-DRGs 374–376 under the CMS definitions manual; the most-searched are listed below.
