871 — Septicemia or Severe Sepsis without MV >96 Hours with MCC

MS-DRG 871, Septicemia or Severe Sepsis without MV >96 Hours with MCC, 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 1.932, so Medicare's base payment for this DRG is about 1.93 times the average inpatient case, before hospital-specific adjustments. The geometric mean length of stay is 4.8 days and the arithmetic mean is 6.3 days.

It belongs to a 2-level severity family: DRG 871 (with MCC, weight 1.932) and DRG 872 (without MCC, weight 1.0066). The highest-severity level carries 1.9 times the weight of the lowest, which is why documenting CC and MCC conditions matters.

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.
