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 SystemW | Anatomical Regions, General |
| 3 | Root OperationH | Insertion Putting in a nonbiological appliance that monitors, assists, performs, or prevents a physiological function but does not physically take the place of a body part |
| 4 | Body Part5 | Lower Jaw |
| 5 | Approach0 | Open |
| 6 | Device1 | Radioactive Element |
| 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 6 MS-DRGs:
- MDC 03 — Other Ear, Nose, Mouth and Throat O.R. Procedures: DRG 143, DRG 144, DRG 145
- MDC 21 — Other O.R. Procedures for Injuries: DRG 907, DRG 908, DRG 909
From the CMS MS-DRG Definitions Manual, Appendix E. Actual DRG assignment depends on the complete claim.
