About B4281ZZ

B4281ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the bilateral renal arteries 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 B4201ZZ (abdominal aorta), B4211ZZ (celiac artery), B4241ZZ (superior mesenteric artery), B42C1ZZ (pelvic arteries), B42F1ZZ (right lower extremity arteries), B42G1ZZ (left lower extremity arteries) and 2 more.

The same procedure with a different approach is coded B4280ZZ (high osmolar), B428YZZ (other contrast) and B428ZZZ (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.
