03LA4CZICD-10-PCS Code: Occlusion of Left Ulnar Artery with Extraluminal Device, Percutaneous Endoscopic Approach
Occlusion L Ulnar Art w Extralum Dev, Perc Endo
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 OperationL | Occlusion Completely closing an orifice or the lumen of a tubular body part |
| 4 | Body PartA | Ulnar Artery, Left |
| 5 | Approach4 | Percutaneous Endoscopic |
| 6 | DeviceC | Extraluminal Device |
| 7 | QualifierZ | No Qualifier |
Potential MS-DRG Relationships (FY2026)
The MS-DRG grouper treats this as an operating room procedure. It appears in the surgical logic of 12 MS-DRGs:
- MDC 05 — Other Vascular Procedures: DRG 252, DRG 253, DRG 254
- MDC 10 — Other Endocrine, Nutritional and Metabolic O.R. Procedures: DRG 628, DRG 629, DRG 630
- MDC 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909
- MDC 24 — Other O.R. Procedures for Multiple Significant Trauma: DRG 957, DRG 958, DRG 959
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
