Potential MS-DRG Relationships (FY2026)

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 10 MS-DRGs:

• MDC 08 — Bilateral or Multiple Major Joint Procedures of Lower Extremity: DRG 461, DRG 462
• MDC 08 — Major Hip and Knee Joint Replacement or Reattachment of Lower Extremity or Total Ankle Replacement: DRG 469, DRG 470
• MDC 08 — Hip Replacement with Principal Diagnosis of Hip Fracture: DRG 521, DRG 522
• MDC 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909
• MDC 24 — Limb Reattachment, Hip and Femur Procedures for Multiple Significant Trauma: DRG 956

From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
