MS-DRG 85 – Traumatic Stupor and Coma <1 Hour with MCC
A Medical DRG in MDC 01 (Diseases & Disorders of the Nervous System). Inpatient cases group to DRG 85 when the ICD-10-CM principal diagnosis is one of the 119 codes listed below and a secondary diagnosis on the major complication or comorbidity (MCC) list is present. Its FY 2026 relative weight is 2.2719 with a geometric mean length of stay of 4.6 days.

How a case is assigned to DRG 85
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 → 85; with CC → 86; without CC/MCC → 87.

Frequently Asked Questions
What is MS-DRG 85?
MS-DRG 85 (Traumatic Stupor and Coma <1 Hour with MCC) is a medical DRG in MDC 01 (Diseases & Disorders of the Nervous System). Its FY 2026 relative weight is 2.2719 with a geometric mean length of stay of 4.6 days.
What is the difference between DRG 85, 86, 87?
All 3 share the same base category; the severity of secondary diagnoses separates them: 85 (with MCC), 86 (with CC), 87 (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 85?
119 ICD-10-CM principal diagnosis codes group to this DRG, spanning 2 three-character categories.
What is the relative weight of DRG 85?
The FY 2026 relative weight of this DRG is 2.2719, meaning reimbursement of roughly 2.27 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
