0PSK05Z ICD-10-PCS Code: Reposition Right Ulna with External Fixation Device, Open Approach
Reposition Right Ulna with Ext Fix, Open 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 SystemP | Upper Bones |
| 3 | Root OperationS | Reposition Moving to its normal location, or other suitable location, all or a portion of a body part |
| 4 | Body PartK | Ulna, Right |
| 5 | Approach0 | Open |
| 6 | Device5 | External Fixation 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 9 MS-DRGs:
- MDC 08 — Shoulder, Elbow or Forearm Procedures, Except Major Joint Procedures: DRG 510, DRG 511, DRG 512
- 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.
