B22310Z ICD-10-PCS Code: Computerized Tomography (CT Scan) of Multiple Coronary Artery Bypass Grafts using Low Osmolar Contrast, Unenhanced and Enhanced
CT Scan Mult Cor A Graft w L Osm Contrast, Unenh, Enhance
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 | SectionB | Imaging |
| 2 | Body System2 | Heart |
| 3 | Root Type2 | Computerized Tomography (CT Scan) Computer reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation |
| 4 | Body Part3 | Coronary Artery Bypass Grafts, Multiple |
| 5 | Contrast1 | Low Osmolar |
| 6 | Qualifier0 | Unenhanced and Enhanced |
| 7 | QualifierZ | None |
