Diagnosis Codes in MS-DRG 870 - Septicemia Or Severe Sepsis With MV >96 Hours

The Medicare Severity Diagnosis-Related Group (MS-DRG) is a patient classification system used to categorize hospital cases based on clinical similarity and expected resource use. MS-DRGs organize all possible principal diagnoses into mutually exclusive groups known as Major Diagnostic Categories (MDCs), which help determine reimbursement under the Medicare Inpatient Prospective Payment System.

This section lists the diagnosis codes included in MS-DRG V42.0: Septicemia or Severe Sepsis with MV >96 Hours from October 1, 2024, through September 30, 2025.

MS-DRG: 870

MS-DRG Title: Septicemia or Severe Sepsis with MV >96 Hours

MCD: 18

Relative Weight: 6.9565 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.

Geometric LOS: 6.96 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.

Arithmetic LOS: 12.80 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.
