03NR0ZZ ICD-10-PCS Code: Release Face Artery, Open Approach
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 |
|---|---|---|

| 2 | Body System3 | Upper Arteries |
| 3 | Root OperationN | Release Freeing a body part from an abnormal physical constraint by cutting or by the use of force |
| 4 | Body PartR | Face 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 3 MS-DRGs:
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
