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 System4 | Lower Arteries |
| 3 | Root OperationN | Release Freeing a body part from an abnormal physical constraint by cutting or by the use of force |
| 4 | Body PartJ | External Iliac Artery, Left |
| 5 | Approach0 | Open |
| 6 | DeviceZ | No Device |
| 7 | QualifierZ | No Qualifier |
Potential MS-DRG Relationships (FY2026)
The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 6 MS-DRGs:
- MDC 05 — Other Vascular Procedures: DRG 252, DRG 253, DRG 254
- MDC 06 — Other Digestive System O.R. Procedures: DRG 356, DRG 357, DRG 358
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
