01HY41Z ICD-10-PCS Code: Insertion of Radioactive Element into Peripheral Nerve, Percutaneous Endoscopic Approach
Insert of Radioact Elem into Periph Nrv, Perc Endo 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 System1 | Peripheral Nervous System |
| 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 PartY | Peripheral Nerve |
| 5 | Approach4 | Percutaneous Endoscopic |
| 6 | Device1 | Radioactive Element |
| 7 | QualifierZ | No Qualifier |
MS-DRG Grouper Relationships (FY2027)
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.
