B221ZZZComputerized Tomography (CT Scan) of Multiple Coronary Arteries

B221ZZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the coronary arteries, multiple using a none approach with none (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 B223ZZZ (coronary artery bypass grafts, multiple) and B226ZZZ (heart, right and left).

The same procedure with a different approach is coded B2210ZZ (high osmolar), B2211ZZ (low osmolar) and B221YZZ (other contrast).

With a different device, use B221Z2Z (intravascular optical coherence).

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.
