The Medicare Severity Diagnosis-Related Group or MS-DRG is a patient classification scheme which provides a means of relating the type of patients a hospital treats. The DRGs divides all possible principal diagnoses into mutually exclusive principal diagnosis areas referred to as Major Diagnostic Categories (MDC). This is the group for MS-DRG - 437 MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITHOUT Complication Comorbidity/Major Complication or Comorbidity diseases in version MS-DRG V38.0 applicable from 10/01/2020 through 09/30/2021.
|MS-DRG||MS-DRG Title||MCD||Relative Weight||Geometric LOS||Arithmetic LOS|
|437||MALIGNANCY OF HEPATOBILIARY SYSTEM OR PANCREAS WITHOUT CC/MCC||07||0.8945 Relative Weight
The relative weight of a diagnostic related group determines the reimbursement rate based on the severity of a patient's illness and the associated cost of care during hospitalization.
|2.40 Geometric Length of Stay
The geometric mean length of stay (GMLOS) is used by Medicare to calculate the reimbursement for patients whose medical treatment takes a much longer or shorter time than average.
|3.00 Arithmetic Length of Stay
The average length of stay (ALOS) reflects the average number of days a patient spends in a hospital for each admission.
