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 System2 | Heart and Great Vessels |
| 3 | Root Operation1 | Bypass Altering the route of passage of the contents of a tubular body part |
| 4 | Body PartW | Thoracic Aorta, Descending |
| 5 | Approach4 | Percutaneous Endoscopic |
| 6 | Device8 | Zooplastic Tissue |
| 7 | QualifierA | Innominate Artery |
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 12 MS-DRGs:
- MDC 01 — Extracranial Procedures: DRG 037, DRG 038, DRG 039
- MDC 05 — Other Major Cardiovascular Procedures: DRG 270, DRG 271, DRG 272
- 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.
