4A01329 ICD-10-PCS Code: Measurement of Peripheral Nervous Conductivity, Sensory, Percutaneous Approach
Measurement of PNS Conductivity, Sensory, Perc 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 | Section4 | Measurement and Monitoring |
| 2 | Body SystemA | Physiological Systems |
| 3 | Root Operation0 | Measurement Determining the level of a physiological or physical function at a point in time |
| 4 | Body System1 | Peripheral Nervous |
| 5 | Approach3 | Percutaneous |
| 6 | Function / Device2 | Conductivity |
| 7 | Qualifier9 | Sensory |
