Potential MS-DRG Relationships (FY2026)

The MS-DRG grouper treats this as a non-operating-room procedure. It appears in the surgical logic of 3 MS-DRGs:

• MDC 09 — Other Skin, Subcutaneous Tissue and Breast Procedures: DRG 579, DRG 580, DRG 581

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