0KJX4ZZ ICD-10-PCS Code: Inspection of Upper Muscle, Percutaneous Endoscopic 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 SystemK | Muscles |
| 3 | Root OperationJ | Inspection Visually and/or manually exploring a body part |

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.
