031409N ICD-10-PCS Code: Bypass Left Subclavian Artery to Left Pulmonary Artery with Autologous Venous Tissue, Open Approach
Bypass L Subclav Art to L Pulm Art w Autol Vn, Open
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 Operation1 | Bypass Altering the route of passage of the contents of a tubular body part |
| 4 | Body Part4 | Subclavian Artery, Left |
| 5 | Approach0 | Open |
| 6 | Device9 | Autologous Venous Tissue |
| 7 | QualifierN | Pulmonary Artery, Left |
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.
