Potential MS-DRG Relationships (FY2026)

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 11 MS-DRGs:

• MDC 08 — : DRG 485, DRG 486, DRG 487
• MDC 08 — Knee Procedures without Principal Diagnosis of Infection: DRG 488, DRG 489
• MDC 10 — Other Endocrine, Nutritional and Metabolic O.R. Procedures: DRG 628, DRG 629, DRG 630
• MDC 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909

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