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 6 MS-DRGs:

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