MS-DRG 871 – Septicemia or Severe Sepsis without MV >96 Hours with MCC
A Medical DRG in MDC 18 (Infectious & Parasitic Diseases, Systemic or Unspecified Sites). Inpatient cases group to DRG 871 when the ICD-10-CM principal diagnosis is one of the 40 codes listed below and a secondary diagnosis on the major complication or comorbidity (MCC) list is present. Its FY 2026 relative weight is 1.9425 with a geometric mean length of stay of 4.8 days.
Severity family
The grouper first assigns the case to MDC 18 from the principal diagnosis and finds no qualifying operating-room procedure (this is a Medical DRG; ICD-10-PCS codes do not drive assignment here), then applies the severity split from secondary diagnoses: with MCC → 871; without MCC → 872.

Frequently Asked Questions
What is MS-DRG 871?
MS-DRG 871 (Septicemia or Severe Sepsis without MV >96 Hours with MCC) is a medical DRG in MDC 18 (Infectious & Parasitic Diseases, Systemic or Unspecified Sites). Its FY 2026 relative weight is 1.9425 with a geometric mean length of stay of 4.8 days.
What is the difference between DRG 871, 872?
All 2 share the same base category; the severity of secondary diagnoses separates them: 871 (with MCC), 872 (without MCC). A major complication or comorbidity (MCC) places the case in the highest-weighted DRG of the family; a CC in the middle; neither in the lowest.
How many diagnosis codes group to DRG 871?
40 ICD-10-CM principal diagnosis codes group to this DRG, spanning 15 three-character categories.
What is the relative weight of DRG 871?
The FY 2026 relative weight of this DRG is 1.9425, meaning reimbursement of roughly 1.94 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
