About B32S1ZZ

B32S1ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the right pulmonary artery 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 computerized axial tomography of thorax, the ICD-9-CM procedure title it maps to (87.41).

For a different body part, codes include B3201ZZ (thoracic aorta), B3251ZZ (bilateral common carotid arteries), B3281ZZ (bilateral internal carotid arteries), B32G1ZZ (bilateral vertebral arteries), B32R1ZZ (intracranial arteries) and B32T1ZZ (left pulmonary artery).

The same procedure with a different approach is coded B32S0ZZ (high osmolar), B32SYZZ (other contrast) and B32SZZZ (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.
