Context: how MS-DRGs work
MS-DRGs bundle hospital inpatient payment into a single amount per admission. Each DRG has a relative weight that multiplies the hospital's base rate to determine payment. 100 has relative weight 1.2842. Major Complication or Comorbidity (MCC) and Complication or Comorbidity (CC) secondary diagnoses can move a case to a higher-paying DRG within the same family.
