B31N0ZZFluoroscopy of Other Upper Arteries using High Osmolar Contrast

B31N0ZZ is the ICD-10-PCS code for a fluoroscopy procedure on the upper arteries, other using a high osmolar 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 intrathoracic vessels and arteriography of other specified sites, the ICD-9-CM procedure titles it maps to (88.44 and 88.49).

For a different body part, codes include B3100ZZ (thoracic aorta), B3110ZZ (right brachiocephalic-subclavian artery), B3120ZZ (left subclavian artery), B3130ZZ (right common carotid artery), B3140ZZ (left common carotid artery), B3150ZZ (bilateral common carotid arteries) and 20 more.

The same procedure with a different approach is coded B31N1ZZ (low osmolar), B31NYZZ (other contrast) and B31NZZZ (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.
