About B300YZZ
B300YZZ is the ICD-10-PCS code for a plain radiography procedure on the thoracic aorta 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 Aortography, the ICD-9-CM procedure title it maps to (88.42).
For a different body part, codes include B301YZZ (right brachiocephalic-subclavian artery), B302YZZ (left subclavian artery), B303YZZ (right common carotid artery), B304YZZ (left common carotid artery), B305YZZ (bilateral common carotid arteries), B306YZZ (right internal carotid artery) and 19 more.
The same procedure with a different approach is coded B3000ZZ (high osmolar), B3001ZZ (low osmolar) and B300ZZZ (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.
