B421ZZZComputerized Tomography (CT Scan) of Celiac Artery

B421ZZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the celiac artery using a none 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 B420ZZZ (abdominal aorta), B424ZZZ (superior mesenteric artery), B428ZZZ (bilateral renal arteries), B42CZZZ (pelvic arteries), B42FZZZ (right lower extremity arteries), B42GZZZ (left lower extremity arteries) and 2 more.

The same procedure with a different approach is coded B4210ZZ (high osmolar), B4211ZZ (low osmolar) and B421YZZ (other contrast).

With a different device, use B421Z2Z (intravascular optical coherence).

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.
