MS-DRG 52 – Spinal Disorders and Injuries with CC/MCC

A Medical DRG in MDC 01 (Diseases & Disorders of the Nervous System). Inpatient cases group to DRG 52 when the ICD-10-CM principal diagnosis is one of the 223 codes listed below and a secondary diagnosis on the CC or MCC lists is present. Its FY 2026 relative weight is 1.7808 with a geometric mean length of stay of 4.1 days.

How a case is assigned to DRG 52

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 CC/MCC → 52; without CC/MCC → 53.

Frequently Asked Questions

What is MS-DRG 52?

MS-DRG 52 (Spinal Disorders and Injuries with CC/MCC) is a medical DRG in MDC 01 (Diseases & Disorders of the Nervous System). Its FY 2026 relative weight is 1.7808 with a geometric mean length of stay of 4.1 days.

What is the difference between DRG 52, 53?

All 2 share the same base category; the severity of secondary diagnoses separates them: 52 (with CC/MCC), 53 (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 52?

223 ICD-10-CM principal diagnosis codes group to this DRG, spanning 8 three-character categories.

What is the relative weight of DRG 52?

The FY 2026 relative weight of this DRG is 1.7808, meaning reimbursement of roughly 1.78 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
