About B30BYZZ

B30BYZZ is the ICD-10-PCS code for a plain radiography procedure on the left external carotid artery using an other contrast 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 specified sites, the ICD-9-CM procedure title it maps to (88.49).

For a different body part, codes include B300YZZ (thoracic aorta), B301YZZ (right brachiocephalic-subclavian artery), B302YZZ (left subclavian artery), B303YZZ (right common carotid artery), B304YZZ (left common carotid artery), B305YZZ (bilateral common carotid arteries) and 19 more.

The same procedure with a different approach is coded B30B0ZZ (high osmolar), B30B1ZZ (low osmolar) and B30BZZZ (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.
