About B31U0ZZ

B31U0ZZ is the ICD-10-PCS code for a fluoroscopy procedure on the pulmonary trunk 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 pulmonary arteries, the ICD-9-CM procedure title it maps to (88.43).

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 B31U1ZZ (low osmolar), B31UYZZ (other contrast) and B31UZZZ (none).

It doesn't appear in the MS-DRG procedure index, so on its own it doesn't change the DRG assignment.

It was added in FY2018, effective October 1, 2017.
