How a case is assigned to DRG 487

The grouper first assigns the case to MDC 08 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 → 485; with CC → 486; without CC/MCC → 487.

Frequently Asked Questions

What is MS-DRG 487?

MS-DRG 487 (Knee Procedures with Principal Diagnosis of Infection without CC/MCC) is a surgical DRG in MDC 08 (Diseases & Disorders of the Musculoskeletal System & Connective Tissue). Its FY 2026 relative weight is 1.5662 with a geometric mean length of stay of 3.5 days.
