How a case is assigned to DRG 142

The grouper first assigns the case to MDC 03 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 → 140; with CC → 141; without CC/MCC → 142.

Frequently Asked Questions

What is MS-DRG 142?

MS-DRG 142 (Major Head and Neck Procedures without CC/MCC) is a surgical DRG in MDC 03 (Diseases & Disorders of the Ear, Nose, Mouth & Throat). Its FY 2026 relative weight is 1.5964 with a geometric mean length of stay of 1.9 days.

What is the difference between DRG 140, 141, 142?

All 3 share the same base category; the severity of secondary diagnoses separates them: 140 (with MCC), 141 (with CC), 142 (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 procedure codes group to DRG 142?

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

What is the relative weight of DRG 142?

The FY 2026 relative weight of this DRG is 1.5964, meaning reimbursement of roughly 1.60 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
