How a case is assigned to DRG 234

The grouper first assigns the case to MDC 05 from the principal diagnosis, then matches a qualifying operating-room procedure from the ICD-10-PCS list below (this is a Surgical DRG), then applies the severity split from secondary diagnoses: with MCC → 233; without MCC → 234.

Frequently Asked Questions

What is MS-DRG 234?

MS-DRG 234 (Coronary Bypass with Cardiac Catheterization or Open Ablation without MCC) is a surgical DRG in MDC 05 (Diseases & Disorders of the Circulatory System). Its FY 2026 relative weight is 5.4627 with a geometric mean length of stay of 8.2 days.

What is the difference between DRG 233, 234?

All 2 share the same base category; the severity of secondary diagnoses separates them: 233 (with MCC), 234 (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 procedure codes group to DRG 234?

361 ICD-10-PCS operating-room procedure codes group to this DRG.

What is the relative weight of DRG 234?

The FY 2026 relative weight of this DRG is 5.4627, meaning reimbursement of roughly 5.46 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
