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 OperationH | Insertion Putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part |
| 4 | Body Part4 | Coronary Vein |
| 5 | Approach4 | Percutaneous Endoscopic |
| 6 | DeviceM | Cardiac Lead |
| 7 | QualifierZ | No Qualifier |
Potential MS-DRG Relationships (FY2026)
The MS-DRG grouper treats this as a non-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.
