How a case is assigned to DRG 336

The grouper first assigns the case to MDC 06 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 → 335; with CC → 336; without CC/MCC → 337.

Frequently Asked Questions

What is MS-DRG 336?

MS-DRG 336 (Peritoneal Adhesiolysis with CC) is a surgical DRG in MDC 06 (Diseases & Disorders of the Digestive System). Its FY 2026 relative weight is 2.1087 with a geometric mean length of stay of 5.1 days.

What is the difference between DRG 335, 336, 337?

All 3 share the same base category; the severity of secondary diagnoses separates them: 335 (with MCC), 336 (with CC), 337 (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 336?

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

What is the relative weight of DRG 336?

The FY 2026 relative weight of this DRG is 2.1087, meaning reimbursement of roughly 2.11 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
