| Position | Value | Meaning |
|---|---|---|
| 1 | Section0 | Medical and Surgical |
| 2 | Body System3 | Upper Arteries |
| 3 | Root OperationU | Supplement Putting in or on biological or synthetic material that physically reinforces and/or augments the function of a portion of a body part |
| 4 | Body Part1 | Internal Mammary Artery, Left |
| 5 | Approach0 | Open |

Potential MS-DRG Relationships (FY2026)
The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 9 MS-DRGs:
- MDC 05 — Other Vascular Procedures: DRG 252, DRG 253, DRG 254
- MDC 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909
- MDC 24 — Other O.R. Procedures for Multiple Significant Trauma: DRG 957, DRG 958, DRG 959
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
