4A133R1 ICD-10-PCS Code: Monitoring of Arterial Saturation, Peripheral, Percutaneous Approach
Monitoring of Arterial Saturation, Peripheral, 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 Operation1 | Monitoring Determining the level of a physiological or physical function repetitively over a period of time |
| 4 | Body System3 | Arterial |
| 5 | Approach3 | Percutaneous |
| 6 | Function / DeviceR | Saturation |
| 7 | Qualifier1 | Peripheral |
