About B42F0ZZ

B42F0ZZ is the ICD-10-PCS code for a computerized tomography (CT scan) procedure on the right lower extremity 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 B4200ZZ (abdominal aorta), B4210ZZ (celiac artery), B4240ZZ (superior mesenteric artery), B4280ZZ (bilateral renal arteries), B42C0ZZ (pelvic arteries), B42G0ZZ (left lower extremity arteries) and 2 more.

The same procedure with a different approach is coded B42F1ZZ (low osmolar), B42FYZZ (other contrast) and B42FZZZ (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.
