About B310YZZ
B310YZZ is the ICD-10-PCS code for a fluoroscopy procedure on the thoracic aorta 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 Aortography, the ICD-9-CM procedure title it maps to (88.42).
For a different body part, codes include B311YZZ (right brachiocephalic-subclavian artery), B312YZZ (left subclavian artery), B313YZZ (right common carotid artery), B314YZZ (left common carotid artery), B315YZZ (bilateral common carotid arteries), B316YZZ (right internal carotid artery) and 20 more.
The same procedure with a different approach is coded B3100ZZ (high osmolar), B3101ZZ (low osmolar) and B310ZZZ (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.
