MS-DRG 441: DISORDERS OF LIVER EXCEPT MALIGNANCY, CIRRHOSIS OR ALCOHOLIC HEPATITIS WITH MCC
MS-DRG 441 is disorders of liver except malignancy, cirrhosis or alcoholic hepatitis with mcc, in MDC 07 (a medical DRG), at the with-MCC (major complication or comorbidity) level. Its FY2027 relative weight is 1.8219, so a case here pays more than the average Medicare inpatient stay (weight 1.0), with a geometric mean length of stay of 4.60 days. 120 ICD-10-CM principal diagnoses group into MS-DRGs 441–443 under the CMS definitions manual; the most-searched are listed below.
