MS-DRG - 816 RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITHOUT CC/MCC

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 - 816 RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITHOUT Complication Comorbidity/Major Complication or Comorbidity diseases in version MS-DRG V40.0 applicable from 10/01/2022 through 09/30/2023.

MS-DRG MS-DRG Title MCD Relative Weight Geometric LOS Arithmetic LOS
816 RETICULOENDOTHELIAL AND IMMUNITY DISORDERS WITHOUT CC/MCC 16 0.7290 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.		 2.20 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.		 2.70 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.
