03140Z4 ICD-10-PCS Code: Bypass Left Subclavian Artery to Left Lower Arm Artery, Open Approach

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 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.
