About B22100Z

B22100Z is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the coronary arteries, multiple using a high osmolar approach with unenhanced and enhanced (qualifier: none). In ICD-10-PCS, computerized tomography (CT scan) means computer reformatted digital display of multiplanar images developed from the capture of multiple exposures of external ionizing radiation.

In plain terms, this corresponds to other computerized axial tomography, the ICD-9-CM procedure title it maps to (88.38).

For a different body part, codes include B22300Z (coronary artery bypass grafts, multiple) and B22600Z (heart, right and left).

The same procedure with a different approach is coded B22110Z (low osmolar) and B221Y0Z (other contrast).

With a different device, use B2210ZZ (none).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It has been valid since ICD-10-PCS took effect on October 1, 2015.
