How a case is assigned to DRG 602

The grouper first assigns the case to MDC 09 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 → 602; without MCC → 603.

Frequently Asked Questions

What is MS-DRG 602?

MS-DRG 602 (Cellulitis with MCC) is a medical DRG in MDC 09 (Diseases & Disorders of the Skin, Subcutaneous Tissue & Breast). Its FY 2026 relative weight is 1.4213 with a geometric mean length of stay of 4.5 days.

What is the difference between DRG 602, 603?

All 2 share the same base category; the severity of secondary diagnoses separates them: 602 (with MCC), 603 (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 diagnosis codes group to DRG 602?

158 ICD-10-CM principal diagnosis codes group to this DRG, spanning 12 three-character categories.

What is the relative weight of DRG 602?

The FY 2026 relative weight of this DRG is 1.4213, meaning reimbursement of roughly 1.42 times the average Medicare inpatient case. Multiply by a hospital's blended base rate for the approximate payment.
