Axis Breakdown
Every ICD-10-PCS code is exactly seven characters, one per axis. Each character's meaning is defined by its position in the code.
| Position | Value | Meaning |
|---|---|---|
| 1 | Section0 | Medical and Surgical |
| 2 | Body System3 | Upper Arteries |
| 3 | Root Operation1 | Bypass Altering the route of passage of the contents of a tubular body part |
| 4 | Body PartL | Internal Carotid Artery, Left |
| 5 | Approach0 | Open |
| 6 | DeviceA | Autologous Arterial Tissue |
| 7 | QualifierJ | Extracranial Artery, Right |
MS-DRG Grouper Relationships (FY2027)
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 12 MS-DRGs:
- MDC 01 — Extracranial Procedures: DRG 037, DRG 038, DRG 039
- 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.
