About B4021ZZ

B4021ZZ is the ICD-10-PCS code for a plain radiography procedure on the hepatic artery using a low osmolar approach with none (qualifier: none). In ICD-10-PCS, plain radiography means planar display of an image developed from the capture of external ionizing radiation on photographic or photoconductive plate.

In plain terms, this corresponds to arteriography of other intra-abdominal arteries, the ICD-9-CM procedure title it maps to (88.47).

For a different body part, codes include B4001ZZ (abdominal aorta), B4031ZZ (splenic arteries), B4041ZZ (superior mesenteric artery), B4051ZZ (inferior mesenteric artery), B4061ZZ (right renal artery), B4071ZZ (left renal artery) and 9 more.

The same procedure with a different approach is coded B4020ZZ (high osmolar) and B402YZZ (other contrast).

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.
