About B32G0ZZ
B32G0ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral vertebral arteries using a high osmolar 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 B3200ZZ (thoracic aorta), B3250ZZ (bilateral common carotid arteries), B3280ZZ (bilateral internal carotid arteries), B32R0ZZ (intracranial arteries), B32S0ZZ (right pulmonary artery) and B32T0ZZ (left pulmonary artery).
The same procedure with a different approach is coded B32G1ZZ (low osmolar), B32GYZZ (other contrast) and B32GZZZ (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.
