About MS-DRG 870
MS-DRG 870, Septicemia or Severe Sepsis with MV >96 Hours, is a medical DRG in MDC 18 (Infectious and Parasitic Diseases, Systemic or Unspecified Sites) under MS-DRG version 44.0, which applies to inpatient discharges from October 1, 2026 through September 30, 2027.
Its FY2027 relative weight is 6.9408, so Medicare's base payment for this DRG is about 6.94 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 12.5 days and the arithmetic mean is 14.9 days.
It is subject to Medicare's post-acute care transfer policy, so payment can be reduced when a patient with a shorter-than-average stay is discharged to a skilled nursing facility, home health or another post-acute setting.
40 ICD-10-CM diagnosis codes are part of this DRG's grouping logic; they are listed below.
