MS-DRG Grouper Relationships (FY2026)

Potential MS-DRG participation — not a DRG assignment.

The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 2 MS-DRGs:

  • MDC 09 — Breast Biopsy, Local Excision and Other Breast Procedures: DRG 584, DRG 585

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