MS-DRG 83 – Traumatic Stupor and Coma >1 Hour with CC

A Medical DRG in MDC 01 (Diseases & Disorders of the Nervous System). Inpatient cases group to DRG 83 when the ICD-10-CM principal diagnosis is one of the 266 codes listed below and a secondary diagnosis on the complication or comorbidity (CC) list is present. Its FY 2026 relative weight is 1.3958 with a geometric mean length of stay of 3.2 days.

How a case is assigned to DRG 83

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 → 82; with CC → 83; without CC/MCC → 84.

Frequently Asked Questions

What is MS-DRG 83?

MS-DRG 83 (Traumatic Stupor and Coma >1 Hour with CC) is a medical DRG in MDC 01 (Diseases & Disorders of the Nervous System). Its FY 2026 relative weight is 1.3958 with a geometric mean length of stay of 3.2 days.

What is the difference between DRG 82, 83, 84?

All 3 share the same base category; the severity of secondary diagnoses separates them: 82 (with MCC), 83 (with CC), 84 (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 83?

266 ICD-10-CM principal diagnosis codes group to this DRG, spanning 2 three-character categories.

What is the relative weight of DRG 83?

The FY 2026 relative weight of this DRG is 1.3958, meaning reimbursement of roughly 1.40 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
