About B31BYZZ

B31BYZZ is the ICD-10-PCS code for a fluoroscopy procedure on the left external carotid artery using an other contrast approach with none (qualifier: none). In ICD-10-PCS, fluoroscopy means single plane or bi-plane real time display of an image developed from the capture of external ionizing radiation on a fluorescent screen. The image may also be stored by either digital or analog means.

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 B310YZZ (thoracic aorta), B311YZZ (right brachiocephalic-subclavian artery), B312YZZ (left subclavian artery), B313YZZ (right common carotid artery), B314YZZ (left common carotid artery), B315YZZ (bilateral common carotid arteries) and 20 more.

The same procedure with a different approach is coded B31B0ZZ (high osmolar), B31B1ZZ (low osmolar) and B31BZZZ (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.
