MS-DRG 94 – Bacterial and Tuberculous Infections of Nervous System with MCC
A Medical DRG in MDC 01 (Diseases & Disorders of the Nervous System). Inpatient cases group to DRG 94 when the ICD-10-CM principal diagnosis is one of the 23 codes listed below and a secondary diagnosis on the major complication or comorbidity (MCC) list is present. Its FY 2026 relative weight is 3.5194 with a geometric mean length of stay of 7.9 days.
Severity family
The grouper first assigns the case to MDC 01 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 → 94; with CC → 95; without CC/MCC → 96.

What is the difference between DRG 94, 95, 96?
All 3 share the same base category; the severity of secondary diagnoses separates them: 94 (with MCC), 95 (with CC), 96 (without CC/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 94?
23 ICD-10-CM principal diagnosis codes group to this DRG, spanning 10 three-character categories.
What is the relative weight of DRG 94?
