Excision of Left Internal Mammary Artery, Perc Endo 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 System3 | Upper Arteries |
| 3 | Root OperationB | Excision Cutting out or off, without replacement, a portion of a body part |
| 4 | Body Part1 | Internal Mammary Artery, Left |
| 5 | Approach4 | Percutaneous Endoscopic |
| 6 | DeviceZ | No Device |
| 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 6 MS-DRGs:
- MDC 04 — Major Chest Procedures: DRG 163, DRG 164, DRG 165
- MDC 05 — Other Major Cardiovascular Procedures: DRG 270, DRG 271, DRG 272
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
