05W00MZ ICD-10-PCS Code: Revision of Neurostimulator Lead in Azygos Vein, Open Approach
Revision of Neuro Lead in Azygos Vein, 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 |
|---|---|---|
| 1 | Section0 | Medical and Surgical |
| 2 | Body System5 | Upper Veins |
| 3 | Root OperationW | Revision Correcting, to the extent possible, a portion of a malfunctioning device or the position of a displaced device |
| 4 | Body Part0 | Azygos Vein |
| 5 | Approach0 | Open |
| 6 | DeviceM | Neurostimulator Lead |
| 7 | QualifierZ | No Qualifier |
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.
