04WY37Z

Potential MS-DRG Relationships (FY2026)

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

• MDC 05 — Other Vascular Procedures: DRG 252, DRG 253, DRG 254

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