About B328YZZ
B328YZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral internal carotid arteries using an other contrast 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 B320YZZ (thoracic aorta), B325YZZ (bilateral common carotid arteries), B32GYZZ (bilateral vertebral arteries), B32RYZZ (intracranial arteries), B32SYZZ (right pulmonary artery) and B32TYZZ (left pulmonary artery).
The same procedure with a different approach is coded B3280ZZ (high osmolar), B3281ZZ (low osmolar) and B328ZZZ (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.
