About B3201ZZ
B3201ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the thoracic aorta using a low 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 B3251ZZ (bilateral common carotid arteries), B3281ZZ (bilateral internal carotid arteries), B32G1ZZ (bilateral vertebral arteries), B32R1ZZ (intracranial arteries), B32S1ZZ (right pulmonary artery) and B32T1ZZ (left pulmonary artery).
The same procedure with a different approach is coded B3200ZZ (high osmolar), B320YZZ (other contrast) and B320ZZZ (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.
